1 to 5 are views showing the configuration of a display device related to the present invention.

Referring to FIG. 1, a display device 10 according to the present invention may include a module unit 100, a first housing 150, and a second housing 190.

The module unit 100 may constitute the body of the display device 10. [ The module section 100 may have a rectangular shape. However, the present invention is not limited thereto, and the module unit 100 may have a shape having a predetermined curvature at an edge. The module unit 100 may include a back cover 130 on the rear surface of the display panel 110. The back cover 130 may be the same size as the display panel 110 or larger than the display panel 110. The back cover 130 can support the rear surface of the display panel 100.

The detailed configuration of the module unit 100 and the function of each configuration will be described later.

The first housing 150 may be located at least a part of the rear surface of the module unit 100. The first housing 150 supports the lower portion of the module unit 100 to prevent the first housing 150 from moving in one direction. The first housing 150 may shield the components that drive the display device 10. [ For example, the first housing 150 may shield at least one printed circuit board (PCB). A detailed coupling structure and a coupling method of at least one printed circuit board will be described later.

The second housing 190 may be positioned on the lower surface of the module unit 100 and the first housing 150. The second housing 190 may extend in a direction perpendicular to a direction in which the module unit 100 and the first housing 150 extend.

The second housing 190 can support the module unit 100 and the first housing 150 so as not to collapse. The second housing 190 is connected to the first housing 150 and may not contact the module unit 100. That is, the module unit 100 is spaced apart from the first housing 150 by a predetermined distance. Accordingly, when the display device 10 is placed on the floor, the impact can be less transmitted to the module unit 100. As a result, the module section 100 can be less cracked.

The second housing 190 can mount at least one printed circuit board (PCB) therein. The at least one PCB may be located at a portion of the second housing 190 that extends to the rear surface of the module unit 100. Accordingly, the width of the second housing 190 may be smaller than the area of the second housing 190 extending to the front surface of the module unit 100 and extending to the rear surface of the module unit 100. Accordingly, the user can see only a small area of the second housing 190, so that the user can be prevented from viewing the screen. The detailed bonding structure and method of at least one PCB will be described later.

The display device 10 according to the present invention can mount at least one PCB occupying a large space in the first and second housings 150 and 190 in a divided manner. Accordingly, the user can feel that the display device 100 is very thin.

Referring to FIG. 2, the module unit 100 may include a display panel 110, a thermal diffusion plate 120, and a back cover 130.

The display panel 110 is provided on the front surface of the module unit 100 and images can be displayed. The display panel 110 may divide the image into a plurality of pixels and output an image by controlling color, brightness, and saturation for each pixel to emit light.

The display panel 110 may be an OLED that emits light by itself to display an image. When the display panel 110 is configured as an OLED, the display device 10 can be configured relatively thinly and lightly. Consumers tend to prefer thin and light display devices 100, and demand for display panels using OLEDs is increasing. Detailed configuration of the display panel 110 will be described later.

The back cover 130 may be positioned on the rear surface of the display panel 110. The back cover 130 may be coupled to the rear surface of the display panel 110 to protect the rear surface of the display panel 110. The back cover 130 can be engaged with the display panel 110 by screws. The back cover 130 may be equal to or larger than the width of the display panel 110 to protect the entire display panel 110.

The back cover 130 may include a transparent material. For example, the back cover 130 may comprise glass or tempered glass. Accordingly, the user can concentrate on the display screen of the thin module section 100 without being conscious of the back cover 130.

The thermal diffusion plate 120 may be positioned between the display panel 110 and the back cover 130. The thermal diffusion plate 120 may be attached to the module section 110 and / or the back cover 130. For example, an adhesive pad and / or a magnet may be attached to one or both surfaces of the thermal diffusion plate 120. The width of the thermal diffusion plate 120 may be smaller than the width of the module unit 110 and the back cover 130 so as not to be exposed to the outside.

The thermal diffusion plate 120 may serve to disperse heat generated in the module unit 110. In other words, it means that a specific region can be prevented from having too high thermal distribution than other regions. For example, the thermal diffusion plate 120 may include a material having good thermal conductivity such as aluminum.

A source PCB 135 and a source COF (Chip on Film) 123 may be positioned on the lower rear side of the display panel 110. The source PCB 135 can be located with signal wires for transmitting timing control signals and digital video data transmitted from the timing controller board. The source PCB 135 can be connected to the display panel 110 by the source COF 123.

The back cover 130 may have at least one hole 142 on the lower surface thereof so that the source PCB 135 can be attached to the rear surface of the display panel 110. At least one hole 142 may correspond to the location of the source PCB 135 when the back cover 130 is coupled to the module portion 110. The back cover 130 may spread heat emitted from the source PCB 135 by the at least one hole 142.

A source PCB cover 145 may be positioned on the backside of at least one hole 142 of the back cover 130 to cover at least one hole 142. [ The source PCB cover 145 can prevent the source PCB 135 from being exposed to the outside. The source PCB cover 145 may include a material having high thermal conductivity such as aluminum. Accordingly, the source PCB cover 145 can diffuse the heat emitted from the source PCB 135. [ The source PCB cover 145 may cover only the hole 142 located on both sides without covering the hole 142 located at the center. That is, the source PCB cover 145 may be located on both sides of the first housing 150, which will be described later. This is because the hole 142 located at the center can be covered by the first housing 150.

The first housing 150 may include a rigid plate 152 and first and second teacone covers 157 and 159. After the rigid plate 152 is coupled to the back surface of the back cover 130, the first and second teacon covers 157 and 159 may be sequentially engaged.

The rigid plate 152 may be a portion on which at least one PCB is mounted. At least the groove may be formed in an area of the rigid plate 152 excluding at least a region where the PCB is mounted. At least one of the grooves may have a shape in which the corresponding region protrudes toward the rear surface of the rigid plate 152. At least one groove can enhance the rigidity of the display device 10. [ That is, it means that the resistance of the back cover 130 against torsional stress applied to the display device 10 can be increased.

At least one PCB may be mounted at the center of the rigid plate 152. For example, at least one PCB may be a timing controller board 155. The timing controller board 155 can transmit an input signal to the module unit 100. That is, the timing controller board 155 means that the timing signals (CLK, LOAD, SPi) controlling the source PCB 135 and the video signals R, G, B can be transmitted to the source PCB 135 do. Also, the timing controller board 155 can control the image. The timing controller board 155 may be connected to the source PCB 135 via a flat flexible cable (FFC). The FFC may include a plurality of signal connection terminal pins and at least one ground terminal pin for connecting the source PCB 135 and the timing controller board 155. [ FFC has the advantage of lower cost than other cables.

The first and second teacon covers 157 and 159 may be positioned on the rear surface of the rigid plate 152. The first and second teacon covers 157 and 159 may cover the rigid plate 152 and the timing controller board 155. That is, the first and second teacon covers 157 and 159 mean that the rigid plate 152 and the timing controller board 155 can be prevented from being exposed to the outside.

The first teacon cover 157 can protect the timing controller board 155 from an external impact. The first teacon cover 157 may be made of a metal material. Accordingly, the first teacon cover 157 can block electromagnetic waves emitted from the timing controller board 155. [ The first teacon cover 157 may have an opening at least in part. The opening may allow heat generated from the timing controller board 155 to be discharged to the outside.

And the second teacon cover 159 may be positioned on the rear surface of the first teacon cover 157. [ The second teacon cover 159 may include the same or similar material as the material of the back cover 130. Accordingly, the user may not feel a sense of heterogeneity between the back cover 130 and the first housing 150 when the user views the display device 10 on the rear surface.

3, the module unit 110 may include a transparent substrate 112, an upper electrode 114, an organic light emitting layer 116, and a lower electrode 118. Referring to FIG. The transparent substrate 112, the upper electrode 114, the organic light emitting layer 116, and the lower electrode 118 may be sequentially formed.

The transparent substrate 112 and the upper electrode 114 may comprise a transparent material. The lower electrode 118 may comprise a non-transparent material. And the lower electrode 118 may include a transparent material (for example, ITO or the like). In this case, light may be emitted to one surface of the lower electrode 118.

When a voltage is applied to the upper and lower electrodes 114 and 118, light emitted from the organic light emitting layer 116 can be transmitted through the upper electrode 114 and the transparent substrate 112 and then externally emitted. At this time, a light shielding plate may be further formed behind the lower electrode 118 to emit light emitted to the lower electrode 118 to the front surface.

The display device according to the present invention may be an OLED display device. Accordingly, a separate light source is not required, and the volume and weight of the display device can be reduced. In addition, the OLED display device has a response speed that is 1000 times faster than that of the liquid crystal display device, so that no afterimage may remain when displaying an image.

Referring to FIG. 4, the display unit 10 according to the present invention may include a transparent material of the module unit 100. That is, the back cover includes a transparent material. For example, the back cover may comprise glass or tempered glass.

The user can enjoy an image or a screen displayed by the module unit 100 when the display device 10 is driven. That is, the module unit 100 means that a screen displayed by the display panel can be displayed.

Alternatively, when the driving of the display device 10 is terminated, backgrounds located behind the module unit 100 can be observed. That is, it means that the background located outside can be observed through the module unit 100.

In the display device 10 according to the present invention, the display portion 250 may be transparent. As a result, the user may feel that the user is apparently neat

Referring to FIG. 5A, the second housing 190 may include a mounting portion MP, a coupling portion CP, and a front portion FP.

The mounting portion MP may be a portion where at least one PCB is mounted. The mounting portion MP may be larger than the engaging portion CP and the front portion FP. That is, in the second housing 190, the mounting portion MP occupies a wider area than the coupling portion CP and the front portion FP. At least one PCB may be spaced apart from one another. The at least one PCB may be connected to each other via the wiring electrode 231.

Each printed circuit board can function differently. In one example, the at least one PCB may be the main board 215. The main board 215 may provide an interface for the display device to operate. In addition, the main board 215 can check and manage the operation state of each component of the display device to make an optimal state. For example, at least one of the main board 215 may be mounted on at least one side of the mounting portion MP, and at least one other may be mounted on the center portion of the mounting portion MP.

In another example, the at least one printed circuit board may be a power supply 107. The power supply 107 may supply power to the display device. The power supply 107 can change the AC frequency to a DC frequency. That is, the power supply 107 changes the low frequency to the high frequency, which means that the electric efficiency can be increased.

The power supply 107 may be spaced apart from the main board 103 by a predetermined distance. For example, the power supply 107 may be located on the opposite side in the first direction with the main board 215 located on one side of the mounting portion MP.

The front portion FP may be a portion located on the front surface of the module portion when the second housing 190 is coupled with the module portion. The front portion FP may be a portion where at least one speaker 164 is mounted. The speaker 164 may be located on both sides of the front part FP. The speaker 164 can output and transmit sound to the user. Accordingly, it is effective that the speaker 164 is located on the front portion FP. At least one speaker 164 may be spaced apart from one another. Accordingly, the user can feel a three-dimensional feeling in the sound transmitted.

The engaging portion CP may be located at the center of the mounting portion MP and the front portion FP. The coupling portion CP may be a portion where the second housing 190 and the first housing are coupled. The coupling portion CP may transfer the electronic signal of the electronic device mounted on the second housing 190 to the first housing. The connecting portion CP can be mounted with the connecting bar 174. The connecting bar 174 may be located in a region corresponding to the first housing when the second housing 190 is coupled to the display device. The connection bar 174 may be provided with a mechanism for connecting the second housing 190 to the first housing. In addition, the electric wiring 231 may penetrate the inside of the second housing 190 to transmit an electric signal from the second housing 190 to the first housing. That is, the connecting bar 174 functions to physically and electrically connect the second housing 190 and the first housing.

The connecting bar 174 may extend in a first direction. Accordingly, the mechanism in which the second housing 190 and the first housing are connected can be dispersed on both sides. In this case, the force to be connected to each of the connected mechanisms may be reduced so that the coupling force between the second housing 190 and the first housing may be stronger.

Referring to FIG. 5 (b), only one main board 215 may be mounted inside the second housing 190. That is, the main board 215 may be positioned on one side of the second housing 190 and the power supply 213 may be positioned opposite to the main board 215 in the first direction. In this case, the overall size of the second housing 190 may be reduced and the appearance may be improved.

6 to 27 are views showing a display device according to an embodiment of the present invention.

Referring to FIG. 6, at least a part of the upper surface of the second housing 190 may be coupled to or separated from the rear surface of the first housing 150 according to the present invention. That is, the display device 10 is configured such that at least a part of the upper surface of the second housing 190 is separated from the rear surface of the first housing 150, Or in a second state coupled with the rear surface of the housing 150. [

The second housing 150 may be coupled to the rear surface of the first housing 190 by rotating in a first direction R1. Also, the second housing 150 may be separated from the rear surface of the first housing 190 by rotating in the second direction R2. For example, the first direction Rl may be a counterclockwise direction and the second direction R2 may be a clockwise direction.

In the first state, the second housing 190 can support the module unit 100 and the first housing 150. That is, in the first state, the user can view the display screen by positioning the second housing 190 at a desired position. In the first state, since the second housing 190 has a large area of the lower surface, the module unit 100 and the first housing 150 can be stably supported.

In the second state, the second housing 190 can be engaged with the attached surface. In the second state, the upper surface of the second housing 190 is coupled to the first housing 150, and the lower surface of the second housing 190 can engage with the attached surface. Since the second housing 190 has a large area on the lower surface, the second housing 190 can stably engage with the surface to be attached. The user can stand the display device 10 or attach it to the wall without using other equipment. The process of changing the second housing 190 from the first state to the second state and its structure will be described later.

Referring to FIG. 7, in a second state, the wall mount assembly 170 may be positioned on the lower surface of the second housing 190 so that the display device 10 can easily engage the attached surface. The wall assembly 170 may be located at the center of the second housing 190.

The width BW of the wall assembly 170 in the second direction may be greater than the width HW of the second housing 190. [ Accordingly, both the upper side and the lower side of the wall-mounted assembly 170 can not be coupled with the second housing 190. In addition, when at least one of the upper side and the lower side of the wall mount assembly 170 is coupled to the back cover 130, a hole may be formed in the back cover 130 to easily form a crack.

Accordingly, the first housing 150 may be provided with a locking bracket 163 protruding upward from the inside in order to maintain the rigidity of the wall mount assembly 170 and the display device 10. The wall assembly 170 may be coupled with the second housing 190 via the at least one screw. The wall assembly 170 may be coupled to the locking bracket 163 via the at least one screw. The locking bracket 163 is positioned inside the first housing 150 in the first state and can protrude outward in the second state. The detailed structure and operation method of the lock bracket 163 will be described later. Since the wall assembly 170 has a larger area than the second housing 190, the wall mount assembly 170 can more stably engage the attachment surface.

Referring to FIG. 8, the second housing 190 and the first housing 150 can be coupled through the hinge 166. The hinge 166 may include a first hinge 166a and a second hinge 166b located on opposite sides of the connecting bar 174. [ The hinge 174 is positioned on both sides of the connecting bar 174 so that the force received by the hinge 166 can be dispersed. Accordingly, the first housing 150 and the second housing 190 are strongly coupled and can not be easily separated.

The hinge 166 may include a protrusion 225 on the opposite side of the side coupled with the connecting bar 174. [ The protrusion 225 can be inserted into the groove 159 formed in the rigid plate 152. Since the groove 159 formed in the rigid plate 152 protrudes toward the rear surface of the rigid plate 152, a space for inserting the protruded portion 225 can be formed. The groove 159 can guide the position where the protrusion 225 is engaged with the rigid plate 152.

The hinge 166 may be shaped such that at least a portion thereof has a convexo-concave part. The concavity and convexity formed on the hinge 166 can improve the rigidity of the hinge 166. Thus, it is possible to increase the resistance of the hinge 166 with respect to the torsional stress that may be applied to the display device 10 when the state changes from the first state to the second state.

And at least one hole 241 for coupling the hinge 166 and the rigid plate 152 to a concave part of the concave and convex portion formed on the hinge 166. [ At least one hole 241 may be located in the recess of the thinner hinge 166. Thus, the rigid plate 152 and the hinge 166 can be joined more strongly. The rigid plate 152 and the hinge 166 can be coupled through at least one hole 241 using at least one screw 243.

The projection device 225 of the hinge 166 can be inserted into and engaged with the groove 159 of the rigid plate 152 in the display device 10 according to the present invention. Accordingly, the coupling position of the hinge 166 is guided so that the first housing 150 and the second housing 190 can be coupled at the correct positions.

9, the hinge 166 may include a body portion 168, a securing portion 172, and an adjuster portion 176. As shown in FIG. Although the first hinge 166a is shown in the figure, the second hinge 166b may also have the same or similar shape.

The body portion 168 may include a protrusion 225, a concave part 253, a convex part 251, a support plate 255, and a hinge bar 312.

The recess 253 may be a recessed portion compared to other portions of the body portion 168. [ Accordingly, the recess 253 may have a short distance for engagement when the hinge 166 engages other materials. That is, the concave portion 253 means that it can engage with other materials with stronger force. The recess 253 may engage other materials through at least one hole 241. [ At least one hole 241 may be symmetrical about at least one other hole 241 and body portion 168. So that the force can be well dispersed when the hinge 166 engages other materials.

The convex portion 251 may be a protruded portion as compared with other portions of the body portion 168. [ That is, the convex portion 251 may protrude in a direction opposite to the depression direction of the concave portion 253. The rigidity of the hinge 166 can be improved due to the recessed portion formed by the recessed portion 253 and the convex portion 251.

The support plate 255 can engage the fixing portion 172 and the adjusting portion 176 with the body portion 168. The support plate 255 may protrude to the opposite side of the portion where the protrusion 225 is formed. The support plate 255 may be coupled to the hinge bar 312 through the at least one screw 243 to which the fixing portion 172 and the adjusting portion 176 are coupled.

One side of the hinge bar 312 is coupled to the support plate 255 and the other side can be directly coupled to the side surface of the body 169. The hinge bar 312 may have a cylindrical shape connecting both sides of the body portion 169. The hinge bar 312 may function as a rotary shaft so that the fixing portion 172 and the adjusting portion 176 can change from the first state to the second state.

The fixing portion 172 can be coupled to the hinge bar 312. That is, the fixing portion 172 means that one side of the hinge bar 312 can wrap around the cylindrical shape. The fixing portion 172 may include a connection portion 268, a housing coupling portion 266, and an adjustment coupling portion 257. [

The connecting portion 268 may be the body of the fixing portion 172. The connection portion 268 may be connected to other components of the fixing portion 172.

The housing coupling portion 266 may extend in a direction orthogonal to the connecting portion 268. The housing coupling portion 266 can couple the hinge 166 with the second housing. The hinge 166 may engage the second housing through at least one hole 241. [ The housing engagement portion 266 extends in the same direction as the interior of the second housing and can be more strongly coupled with the second housing. The second housing can be supported only by the coupling force between the housing coupling portion 266 and the second housing in the second state. Accordingly, the housing engagement portion 266 may include a material having high strength.

The adjustment coupling portion 257 may be configured to surround the adjustment portion 176. [ The adjustment coupling portion 257 may be configured to surround the cylindrical columnar portion 323. Accordingly, the portion where the adjustment coupling portion 257 is located may be larger in diameter than the column portion 323 of the adjustment portion 176. The spring 339 can be caught by the adjustment coupling portion 257 due to the difference in diameter of the portion where the adjustment coupling portion 257 is located. The adjusting portion 257 can be used to fix the adjusting portion 176 to the hinge bar 312 by using the elastic force of the spring 339. [

The adjustment portion 176 can fix the hinge 166 in the first state or the second state using the elastic force of the spring 339. [ That is, the adjustment portion 176 is fixed to extend in the same direction as the body portion 168 in the first state and can be fixed to extend in the direction perpendicular to the body portion 168 in the second state.

The adjustment portion 176 may include a spring 339, a column 323, an insertion portion 317, and a thumb screw 341. [

The spring 339 can be inserted into the column 323. More specifically, when the adjustment portion 176 and the fixing portion 172 are engaged, they can be positioned between the adjustment coupling portion 257 and the end of the column 323. [ The spring 339 may be in a relaxed state by being stretched by an elastic force in the first state. In this case, the insertion portion 344 can be inserted into the insertion hole 317 of the hinge bar 312 by the elastic force of the spring 339. Thus, the hinge 166 can be fixed without being moved by an external force.

The insertion portion 344 may protrude from one end of the adjustment portion 176. [ The insertion portion 344 is inserted into the insertion hole 317 of the hinge bar 312 in the first state and can be separated from the insertion hole 317 when the state changes to the second state.

The thumbscrew 341 may be located at the other end of the adjustment portion 176. The thumbscrew 341 may have an annular shape so that the user can easily grasp and adjust it. The thumbscrews 341 are provided on the side of the main body so as not to protrude the annular shape. Can be. On the other hand, when the user adjusts the thumbscrew 341, the ring shape can be set to be sideways and easily pulled. The thumbscrew 341 can help the user apply an external force to the adjuster 176.

Referring to FIG. 10, the insertion portion 344 can be separated from the insertion hole 317 so as to change from the first state to the second state. The user can pull the thumbscrew 344 to retract the spring 339. [ That is, the user can apply the external force F1 to the column portion 323 to cause the spring 339 to contract. The external force F1 may be equal to or greater than the elastic force of the spring 339. [ The spring 339 is retracted and the insertion portion 344 can be pulled like the column portion 323. [

After the insertion portion 344 is separated from the insertion hole 317, the fixing portion 172 can be rotated. The user can rotate the fixing portion 172 such that the second housing coupled with the fixing portion 172 changes to the second state. In order not to be disturbed by the elastic force of the spring 339, the user can rotate the fixing portion 172 while pulling the thumbscrew 344 pulled. However, the present invention is not limited thereto, and the fixing portion 172 may be rotated without pulling the thumbscrew 344 at a portion not corresponding to the insertion hole 317.

Since the second housing 190 coupled with the fixing portion 172 also rotates when the fixing portion 172 is rotated, much force may be required for rotation. Accordingly, it is more preferable to rotate the thumbscrew 344 in a pulled state because there is no frictional force between the hinge bar 312 and the insertion portion 344.

Referring to FIG. 11, in the second state, the body portion 168, the adjusting portion 176, and the engaging portion 172 may be orthogonal. The insertion portion 344 may not correspond to the insertion hole of the hinge bar 312 in the second state. Accordingly, the insertion portion 344 may not be inserted into the hinge bar 312 but may be in contact with the outside. The insertion portion 344 can be pushed toward the hinge bar 312 due to the elastic force of the spring 339. [

In the second state, the engaging portion 172 can support the entire second housing. Accordingly, in the second state, the adjustment portion 176 can be fixed to the hinge bar 312. [ Otherwise, the force to support the second housing may be insufficient to return from the second state to the first state. A method in which the adjusting portion 176 is fixed to the hinge bar 312 in the second state will be described later.

12, a rail portion 196 protruding to the side surface of the fixing portion 172 can be inserted into the guide groove 199 so that the fixing portion 172 can move only within the first state and the second state . The portion where the guide groove 199 is located may be smaller in diameter than other portions. The rail portion 196 can be limited by the hinge bar 312 when it is attempted to move beyond the portion where the guide groove 199 is located. Thereby, when the second housing is changed to the first state or the second state, there is an unexpected movement and the risk of cracking or breaking is low.

As shown in Fig. 12 (a), the rail portion 196 may be positioned between a state of facing the front surface corresponding to the first state and a state facing the lower surface corresponding to the second state. For this purpose, the guide groove 199 may be positioned between 0 and 90 degrees counterclockwise with respect to the front direction of the hinge bar 312. In this case, in the first state, the rail portion 196 may not rotate the fixing portion 172 at an angle of 0 degrees or less in the counterclockwise direction. And may not rotate at an angle of 90 degrees or more in the counterclockwise direction in the second state.

Alternatively, as shown in FIG. 12 (b), the guide groove 199 may be positioned in the counterclockwise direction from 0 ° to 90 ° with respect to the front direction of the hinge bar 312. In addition, the guide groove 199 may be further formed in a straight line at an angle of 90 degrees in the counterclockwise direction of the hinge bar 312. In this case, the rail portion 196 may not rotate by more than 90 degrees in the counterclockwise direction due to the hinge bar 312 in the second state.

The guide groove 199 according to the present embodiment can be prevented from directly blocking the rail portion 196 in the second state as compared with the guide groove 199 shown in Figure 12 (a). Accordingly, the manufacturing process is simple and the cost can be low.

Referring to FIG. 13, the first and second hinges 166a and 166b may be coupled to the connecting bar 174. The hinge bar 312 can be inserted into the opening 375 located on both sides of the connecting bar 174 and can be engaged. The hinge bar 312 may be inserted into the connecting bar 174 and then engage with the second housing through the engaging portion 172.

The connecting bar 174 may include an opening 375, at least one hole 241, and a through hole 278. The connection bar 174 has a central portion protruded to facilitate insertion of the hinge 166 or the electric wiring therein.

The through hole 278 may be located at the center of the connecting bar 174. The through-hole 278 can penetrate the side surface of the projection of the connecting bar 174. The through hole 278 may be a passage through which electrical wiring is inserted to electrically connect the first housing and the second housing.

At least one hole 241 may be formed in the protruding portion of the connecting bar 174. At least one hole 241 may pass through the connection bar 174 from the top to the bottom. At least one hole 241 may be provided to couple the connecting bar 174 to the interior of the second housing.

Referring to FIG. 14, in the display device 10 according to the present invention, the through bolt 351 penetrates through the second housing 190 in the first state and can be coupled with the first housing 150. In the first state, the through bolt 351 can engage with the lower surface of the first housing 150 through at least one hole 241 passing through the second housing 190.

At least one hole 241 may be located on either side of the hinge hole 194 into which the wing bolt of the hinge is inserted. Since the hinge holes 194 are located on both sides of the second housing 190, at least one hole 241 located on both sides of the hinge hole 194 is provided on each side of the second housing 190, Four can be located. In this case, since the penetrating bolt 351 joins the first housing 150 and the second housing 190 on both sides, the force can be easily dispersed. Accordingly, the first housing 150 and the second housing can be more easily coupled.

Referring to FIG. 15, the through bolt 351 may include a first screw region 393 and a second screw region 395. The first threaded region 393 may have a first diameter SD1 and the second thread 395 may have a second diameter SD2. The first diameter SD1 may be greater than the second diameter SD2.

At least one hole of the second housing may engage the first diameter SD1 and at least one hole of the first housing may engage the second diameter SD2. The second diameter SD2 of the second threaded region 395 can easily pass through the hole because it is smaller than the first diameter SD1 of at least one hole of the second housing. Accordingly, the through bolt 351 can engage with the second housing when the first screw region 393 is tightened. The second threaded region 395, which easily escapes through the second housing, can engage the first housing. Accordingly, when changing from the first state to the second state, the through bolts 351 can be coupled with the first and second housings 150 and 190 more quickly than when the diameters of all the parts are the same.

16, the display device 10 according to the present invention may further include a hinge cover 413 for shielding the hinge 166 exposed between the connecting bars 174. [

The hinge 166 may be exposed between the connecting bars 174 when the first housing 150 and the second housing 190 are engaged. In this case, since the hinge 166 is comprised of a material other than the connecting bar 174 (e.g., the hinge 166 includes metal and the connecting bar 174 includes plastic) It can be recognized that it is not clean.

Accordingly, the hinge cover 413 can be positioned to surround the side surface of the connecting bar 174. The attachment member 421 may be positioned at a position corresponding to the exposed hinge 166, as shown in FIG. 16 (b). The attachment member 421 may include a magnetic substance. The hinge 166 can be coupled to the attachment member 421 more strongly because it includes a metal.

The hinge cover 413 may be attached to the connecting bar 174 of the display device 100 according to the present invention. Accordingly, the user can recognize that the appearance is clean.

Referring to FIG. 17, the position of the lock bracket 163 may be different in the first and second states of the display device 10 according to the present invention. 17 (a), in the first state, the lock bracket 163 may protrude from the lower side of the first housing 150 on one side. The user can adjust the handle 442 located at the center of the lock bracket 163 to position the lock bracket 163 downward.

17 (b), in the second state, the lock bracket 163 may protrude to the upper portion of the first housing 150 at the other side. The user can adjust the knob 442 located at the center of the lock bracket 163 to position the lock bracket 163 upward.

The handle 442 can be exposed to the outside through the guide bracket 437 of the first housing 150. The handle 442 can protrude from the locking bracket 163 to the rear surface of the display device 10. [

The guide bracket 437 can guide a position at which the lock bracket 163 moves up and down. The width of the guide bracket 437 in the first direction may be smaller than the diameter of the handle 442. Accordingly, the handle 442 may not be inserted into the guide bracket 437.

Referring to FIG. 18, in the display device 10 according to the present invention, the locking bracket 163 protruding from the lower portion of the first housing 150 in the first state can be coupled to the second housing 190.

The protruding portion of the lock bracket 163 can be inserted into the groove located in the second housing 190. The groove can be engaged with the protruding portion of the lock bracket 163. A method of joining the lock bracket 163 and the second housing 190 will be described later. Accordingly, in the first state, the module section 100 can be fixed without rocking back and forth. The user can fix the module unit 100 and concentrate more on the display screen.

19, the protruding portion of the lock bracket 163 can be inserted into the groove 466 located in the second housing 190. [ The groove 466 may have a width HMW3 in the third direction equal to or similar to the thickness BW of the lock bracket 163. Accordingly, the locking bracket 163 can be fixed in the groove 466 without shaking back and forth.

The length of the locking bracket 163 protruding to the lower side may be shorter than the thickness of the second housing 190. Accordingly, even if the handle 442 is moved to the lowermost end of the guide bracket 437, the protruded portion of the lock bracket 163 may not exceed the thickness of the second housing 190.

 Referring to FIG. 20, the locking bracket 163 can be coupled through the rear surface of the first housing 150 using at least one screw 243. In this case, at least one screw 243 may be coupled to the rigid plate of the first housing 150 through the locking bracket 163. At least one screw 243 may be coupled with the back cover 130 through the lock bracket 163.

The second housing 190 may be coupled with the lower surface of the locking bracket 163 through the through bolt 351 to couple the locking bracket 163 and the second housing 190 together. The detailed structure of the lock bracket 163 will be described later.

The display device 10 according to the present invention can be fastened at the rear surface and the bottom surface so that the locking bracket 163 does not move in the first state. Accordingly, since the module unit 100 does not move, the user can concentrate on the display screen.

Referring to FIG. 21, the locking bracket 163 includes a stopper 441 and a wall-fixing groove 482 in the front portion thereof, and a second housing locking groove 192 may be located in the lower surface thereof.

The stopper 441 may have a shape recessed into the lock bracket 163. The stopper 441 may function to guide the movement end point when the lock bracket 163 moves up and down. The stopper 441 may include at least one hole 241. [ The at least one hole 241 may function to fix the lock bracket 163 through the screw when the first state or the second state. The stopper 441 can be inserted with a sliding member 411 to be described later. The thickness HMT of the stopper 441 may be smaller than the thickness HIT of the lock bracket 163. Accordingly, the stopper 441 may not penetrate the lock bracket 163.

The walled groove 482 may be a portion that engages with the wall bracket assembly when in the second state. As shown in Fig. 7, in the second state, the upper part of the wall-mounting assembly and the wall-fixing groove 482 can be coupled through a screw. Since the wall-like groove 482 is a portion to be coupled with the wall-hanging groove 482 having a gap, the diameter can be larger than the other holes.

The second housing coupling groove 192 can fasten the locking bracket 163 and the second housing through the through bolts. The second housing coupling groove 192 may also be larger than the holes of different diameters.

The sliding member 411 may be located inside the stopper 441 of the lock bracket 163. The sliding member 411 can guide the moving position of the locking bracket 411. The sliding member 411 may include a material having a low frictional force so that the locking bracket 163 can easily flow. For example, the sliding member may comprise a POM material. The sliding member 441 includes a locking part 436 on the upper side and a lower side and may include a plate fastening part 452 in the center part.

The locking portion 436 can be fastened to the first housing together with the locking bracket 163 in the first or second state. The distance HD between the at least one hole 241 of the stopper 441 may be equal to the spacing SPD between the locking portions 436. [ The locking portion 436 may have a protruding shape so as to be easily fastened even if the length of the screw is short.

The plate fastening portion 452 can fix the sliding member 411. More specifically, the plate fastening portion 452 can fasten the sliding member 411 to the rigid plate 152 using a screw. The plate fastening portion 452 may be surrounded by the side wall 474 so that the screw does not contact the stopper 441. [

22, in the first state, at least one hole 241 and a locking portion 436 located on the upper side of the stopper 441 are screwed into the screw 243, as shown in FIG. 22 (a) Lt; / RTI > In this case, the lower portion of the lock bracket 163 may be exposed to the outside of the first housing 150.

22 (b), in the second state, at least one hole 241 and a locking portion 436 located below the stopper 441 are coupled through the screw 243, can do. In this case, the upper portion of the lock bracket 163 may be exposed to the outside of the first housing 150.

The sliding member 411 located inside may not move when the state changes from the first state to the second state. When the stopper 441 abuts on the upper side or the lower side of the sliding member 411, the user can easily recognize whether the first state or the second state is reached. Also, in the first state or the second state, since the locking part 436 and the at least one hole 241 overlap, the screw 243 can be easily engaged only in the two states described above.

23 and 24, the sliding member 411 may include a side guide 513 and a guide protrusion 524 which can guide the locking bracket more accurately at the bottom.

The side guides 513 can extend from both sides of the sliding member 411. The width extending to both sides may be greater than the width of the locking bracket 163. On both sides of the side guide 513, a guide protrusion 524 can be positioned. The guide protrusion 524 may protrude in the same direction as the protruding direction of the locking portion 436 of the sliding member 411. [ The guide protrusion 524 may protrude less than the locking portion 436. [ However, the present invention is not limited thereto, and the guide protrusion 524 may protrude higher than the locking portion 436.

The distance GD between the guide protrusions 524 may be equal to or larger than the width of the lock bracket 163. [ Accordingly, the lock bracket 163 can be placed between the guide protrusions 524.

The guide protrusion 524 can guide the locking bracket 163 not to be tilted to both sides when the locking bracket 163 is moved to a state of either the first state or the second state.

Referring to FIG. 25, the display device 10 according to the present invention may include a fixing bracket 534 for connecting the first housing 150 and the second housing 190 in a second state.

The fixing bracket 534 may be positioned on both sides of the first and second housings 150 and 190. The fixing bracket 534 may be fixed in a second state such that the rear surface of the first housing 150 and the second housing 190 are in contact with each other without the wall-mounted assembly. One end of the fixing bracket 534 is coupled with the first housing 150 and the other end is coupled with the second housing 190. The first housing 150 and the second housing 190 may not be fixed when the gap between the one end and the other end of the fixing bracket 534 becomes wide. Accordingly, the fixing bracket 534 may include a material having high strength. For example, the fixing bracket 534 may comprise a metal material.

The display device 10 according to the present invention can fix the fixing bracket 534 so that the first housing 150 and the second housing 190 maintain the second state. Accordingly, in the second state, the first housing 150 and the second housing 190 are separated from each other, so that the risk of cracking or breakage can be reduced.

Referring to FIGS. 26 and 27, the fixing bracket 534 may include first and second protrusions 539 and 547 and a hanger 521.

The first projecting portion 547 can constitute one end of the fixing bracket 534. The first projection 547 may be bent in a direction orthogonal to the body of the fixing bracket 534. For example, when the body extends in the horizontal direction, the first projection 547 may be bent in the upper vertical direction.

The first projection 547 may be bent in a direction opposite to the direction in which one end of the first projection 547 extends. That is, one end of the first projection 547 may be bent in the lower vertical direction. Since the first protrusion 547 is bent at one end, the first protrusion 547 can be easily inserted into the first housing 150.

The first projection 547 can be inserted into the fixing groove 507, which has one end on both sides of the upper end of the first housing 150. In order to engage the first housing 150 and the second housing 190 in the second state, the first protrusion 547 may require only vertical force. Accordingly, the first protrusion 547 can fix the first housing 150 and the second housing 190 without being coupled to the first housing 150 through a screw.

The second projection 539 can constitute the other end of the fixing bracket 534. The second projection 539 may extend in a direction orthogonal to the body of the fixing bracket 534. For example, when the body extends in the horizontal direction, the second projection 539 may extend in the lower vertical direction.

In the second state, the second projection 539 can contact at least one side of the second housing 190. In the second state, the second projection 539 can engage with the second housing 190 through the screw 243. The first housing 150 and the second housing 190 can be more strongly fixed because the second projection 539 and the second housing 190 are coupled through the screw 243. [

The hook 521 may extend in the same direction as the body on the upper side of the body. The hanging part 521 may be a part where electric wiring or the like is stuck. When placing electrical wiring in the hanging 521, the user may feel that the wiring is easier to clean and the appearance is cleaner. However, the present invention is not limited thereto, and as shown in FIG. 27 (b), the fixing bracket 534 may not include the hook 521. In this case, the manufacturing process of the fixing bracket 534 is simplified and the cost can be saved.

The foregoing detailed description should not be construed in all aspects as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
