The display module structure of current display devices is generally shown in Figure 1, and single-sided packaging is usually used to achieve extremely narrow borders and thin and light design requirements. The specific packaging method is to flip the cable back and place the drive circuit or edge glass behind the display panel to achieve an extremely narrow border design for the entire product. However, for display modules connected to multiple drive circuits or edge glasses, the back-flip installation design will cause multiple drive cables or edge glasses to occupy space with each other, making them difficult to fix, which brings difficulties to the multi-sided packaging of the display device.

In view of the defects of the prior art, the embodiment of the utility model provides a display device, as shown in Figures 2-16, the display device includes a packaging structure and a display module 3 packaged in the packaging structure. Specifically, the packaging structure includes a housing and a mounting frame, and the display module 3 is accommodated in the housing 1 through the mounting frame 2.

The housing 1 includes an upper frame 11 and a bottom shell 12. When the display module 3 is installed on the mounting frame 2, the mounting frame 2 with the display module 3 is accommodated in the bottom shell 12, and then the upper frame 11 is covered on the light-emitting side of the display module 3 to complete the packaging of the display device.

The structure of the display module 3 is shown in FIG2 , and includes a display panel 31 and a first drive circuit, a second drive circuit, a third drive circuit and a fourth drive circuit which are arranged on the four edges of the display panel 31 through a flat cable 36 . The flat cable 36 is used as a connecting wire to connect the first drive circuit, the second drive circuit, the third drive circuit and the fourth drive circuit to the display panel 31 so as to light up the screen.

In a specific embodiment, the flat cable 36 is a COF (Chip on film) connection line, which mainly includes an organic layer, an inorganic layer, a metal layer, etc., has certain metal properties, can be bent, can rebound, and is not easy to deform. The display panel 31 and the first drive circuit, the second drive circuit, the third drive circuit and the fourth drive circuit are connected through the flat cable 36, so that the drive circuit and the display panel 31 can be effectively connected, so that the display panel 31 can be controlled by the drive circuit to display. In addition, the metal property of the flat cable 36 allows it to be bent during installation, so that the first drive circuit, the second drive circuit, the third drive circuit and the fourth drive circuit can be installed in corresponding positions as needed, and will not affect the effective connection between the drive circuit and the display panel 31.

In this embodiment, the first drive circuit, the second drive circuit and the third drive circuit are shown as drive circuit layers arranged on the glass substrate. Specifically, the first drive circuit, the second drive circuit and the third drive circuit are respectively arranged on the first side glass 32, the second side glass 33 and the third side glass 34 of the rectangular structure. The first side glass 32, the second side glass 33 and the third side glass 34 are respectively coupled to the display panel through the wiring 36 to achieve effective connection between the first drive circuit, the second drive circuit and the third drive circuit and the display panel 31. In this embodiment, in combination with FIG. 2, the orientation relationship in the figure is described, the first side glass 32 is installed on the upper side of the display panel 31 through two sets of wiring 36, and the second side glass 33 and the third side glass 34 are installed on the left and right sides of the display panel 31 through two sets of wiring 36. The fourth drive circuit is shown as a PCB drive circuit board (not shown in the figure), which is installed on the lower side of the display panel 31 through the wiring 36. This wiring 36 is only limited and not fixed during packaging. For the convenience of distinction, this wiring is called an active wiring 35 in this embodiment.

In a specific embodiment, as shown in FIGS. 4-6 , the mounting frame 2 includes a first mounting surface 211 and a second mounting surface 221 that are disposed opposite to each other, and a receiving cavity 23 is included between the first mounting surface 211 and the second mounting surface 222, and the receiving cavity 23 runs through the first side surface (the front side surface in FIG. 4 ) and the second side surface (the rear side surface in FIG. 4 ) of the mounting frame 2, wherein the first side surface and the second side surface are disposed opposite to each other, and the first side surface and the second side surface are disposed perpendicular to the first mounting surface 211. The mounting frame 2 as a whole presents a double-layer structure, so as to facilitate the layered installation of the first side glass 32, the second side glass 33 and the third side glass 34, avoid the first side glass 32, the second side glass 33 and the third side glass 34 from occupying space with each other, and facilitate the installation and fixing of the first side glass 32, the second side glass 33 and the third side glass 34. The opposite arrangement mentioned in this embodiment can be understood as the second mounting surface 222 being located on the side of the mounting frame 2 away from the first mounting surface 211.

In this embodiment, as shown in FIG. 10 and FIG. 13 , the display panel 31 is mounted on the first mounting surface 211. The first edge glass 32 is mounted on the upper side of the display panel 31 through the wiring 36 and is coupled to the display panel 31. After the display panel 31 is mounted on the first mounting surface 211, the wiring 36 of the first edge glass 32 is bent toward the back side of the display panel 31, and the first edge glass 32 is accommodated in the accommodating cavity 23. The second edge glass 33 and the third edge glass 34 are respectively mounted on the left and right sides of the display panel 31 through the wiring 36 and are coupled to the display panel 31. As shown in FIGS. 11-12 , after the first side glass 32 and the active cable 35 are installed, the cables 36 of the second side glass 33 and the third side glass 34 are bent toward the back side of the display panel 31, respectively, so that the second side glass 33 and the third side glass 34 cover the left and right parts of the second installation surface 221, respectively, and the second side glass 33 and the third side glass 34 are pressed tightly by the pressing sheet 4 to limit the second side glass 33 and the third side glass 34. With such a design, the first side glass 32, the second side glass 33, and the third side glass 34 can be fixed in layers, avoiding the problem of being unable to be fixed due to insufficient installation space.

Further, as shown in FIG4 , the installation frame 2 further includes a wiring opening 24 that penetrates the installation frame, and the extension direction of the wiring opening 24 is perpendicular to the extension direction of the accommodating cavity 23, and penetrates from the first installation surface 211 to the second installation surface 221, and the wiring opening 24 is used to limit the position of the movable cable 35. Specifically, as shown in FIG10 , after the display panel 31 is placed on the first installation surface 211, the movable cable 35 is bent toward the back side and inserted into the wiring opening 24, so that the movable cable 35 extends from the first installation surface 211 to the second installation surface 221, and the movable cable 35 is confined in the wiring opening 24, and the position of the movable cable 35 is limited but not fixed, so that it remains in a free bending state, and a narrow frame design on the ground side is realized.

In a specific embodiment, as shown in FIG. 4 and FIG. 13 , the mounting frame 2 is a double-layer structure with a hollow interior, specifically including a first structural layer 21 and a second structural layer 22 that are arranged in parallel and connected to each other, and a receiving cavity 23 is formed between the first structural layer 21 and the second structural layer 22 to form a hollow structure of the mounting frame 2. In this embodiment, the first mounting surface 211 is located on the side of the first structural layer 21 away from the second structural layer 22, and is used to carry the display panel 31; the second mounting surface 221 is located on the side of the second structural layer 22 away from the first structural layer 21, and is used to carry the second edge glass 33 and the third edge glass 34. The receiving cavity 23 is formed between the first structural layer 21 and the second structural layer 22, and is used to accommodate the first edge glass 32 and confine the first edge glass 32 between the first structural layer 21 and the second structural layer 22.

In a preferred example, the second structural layer 22 includes a first edge portion (not shown in the figure) and a second edge portion 222 protruding from the edge of the first structural layer 21 on both sides corresponding to the first driving circuit and the fourth driving circuit, and the first edge glass 32 is accommodated in the accommodating cavity 23 through an opening located between the first structural layer 21 and the first edge portion (not shown in the figure).

In this embodiment, the wiring opening 24 is opened at the second edge portion 222 and passes through the two side surfaces of the second structure layer 22. The active cable 35 is led out from the ground side of the display panel 31, freely bends and passes through the wiring opening 24, and is led out to the side where the second mounting surface 221 is located.

In a specific embodiment, as shown in FIG. 5 and FIG. 6 , the second mounting surface 221 is an I-shaped structure, including a vertical beam portion 2211 extending along the center line in the length direction of the second structural layer 22, and a first groove portion 2212 and a second groove portion 2213 respectively located at two opposite sides of the vertical beam portion 2211. The first groove portion 2212 and the second groove portion 2213 are recessed structures, and the second side glass 33 and the third side glass 34 are respectively accommodated in the first groove portion 2212 and the second groove portion 2213.

After the second side glass 33 and the third side glass 34 are installed in the first groove portion 2212 and the second groove portion 2213, the second side glass 33 and the third side glass 34 need to be limited by the pressing plate 4. Specifically, the pressing plate 4 is installed on the vertical beam portion 2211 through a fastener 41, and the fastener 41 can be a fastener such as a screw, a bolt or a stud. There is a locking and anti-loosening structure between the pressing plate 4 and the fastener 41, that is, the fastener 41 can be screwed in and out of the vertical beam portion 2211 as the pressing plate 4 rotates, and the pressing plate 4 and the fastener 41 are always in a fixed connection state.

The pressing plate 4 includes a locked state and an unlocked state relative to the second side glass 33 and the third side glass 34. The pressing plate 4 can be transformed between the locked state and the unlocked state by screwing the locking member 41 in and out on the vertical beam 2211. As shown in Figures 6-7, in the unlocked state, the pressing plate 4 overlaps with the vertical beam 2211, which facilitates the installation and removal of the second side glass 33 and the third side glass 34; as shown in Figures 5 and 8, in the locked state, the pressing plate 4 and the vertical beam 2211 form a cross structure, and the pressing plate 4 presses the second side glass 33 and the third side glass 34, so that the second side glass 33 and the third side glass 34 are respectively in contact with the second mounting surface 221 and the pressing plate 4, thereby realizing the position limitation of the second side glass 33 and the third side glass 34.

In this embodiment, the vertical beam 2211 includes at least one pressing plate 4, and each pressing plate 4 is installed on the vertical beam 2211 through a fastener 41. As shown in Figure 9, the pressing plate 4 is rectangular, and a countersunk hole corresponding to the fastener 41 is opened in the center. The fastener 41 is connected and fixed to the pressing plate 4 through the first silicone gasket 42 and the second silicone gasket 43 to achieve a locking connection between the fastener 41 and the pressing plate 4. Specifically, the first silicone gasket 42 and the second silicone gasket 43 are both sleeved on the fastener 41, respectively located on both sides of the pressing plate 4, and abutting against the upper and lower surfaces of the pressing plate 4. Further, the first silicone gasket 42 is located on the side of the pressing plate 4 away from the vertical beam 2211, and the second silicone gasket 43 is located on the side of the pressing plate 4 close to the vertical beam 2211. A metal gasket 44 is also included between the first silicone gasket 42 and the screw head. The metal gasket 44 is sleeved on the screw of the fastener 41 and abuts against the screw head and the first silicone gasket 42 respectively.

In one embodiment, as shown in FIG4 , the four corners of the mounting frame 2 include fixing posts 25, and the center of the fixing posts 25 is provided with a mounting hole 250 for connecting and fixing the mounting frame 2 to the housing 1. Specifically, the mounting frame 2 is installed in the bottom housing 12 through the mounting hole 250.

The display panel 31 is installed between the four fixing columns 25. The four fixing columns 25 corresponding to the corners of the display panel 31 include a limiting structure to limit the displacement of the display module 3 on the first mounting surface 211 to ensure the installation accuracy. As shown in FIG. 15, one of the fixing columns 25 is used for illustration. The top of the fixing column 25 includes a surrounding portion 251 formed on the periphery of the mounting hole 250. The surrounding portion 251 forms a receiving space to accommodate the mounting hole 250. The surrounding portion 251 includes an opening 252 near the corner of the display panel 31. The presence of the opening 252 allows the corner of the display panel 31 to enter the receiving space when it is installed, avoiding collision with the fixing column 25 and causing damage to the corner, thereby improving the yield rate of the product.

When packaging the display device, the display module 3 and the mounting frame 2 are first assembled, the display panel 31 is mounted on the first mounting surface 211, the first side glass 32 is inserted into the accommodating cavity 23, the active cable 35 is inserted into the wiring opening 24, the second side glass 33 and the third side glass 34 are turned over to the first groove portion 2212 and the second groove portion 2213, and fixed by the pressing sheet 4. Then the mounting frame 2 is installed in the bottom shell 12, and the front frame 11 is covered on the light-emitting surface of the display module 3.

Since the cable 36 has a rebound force, when the mounting frame 2 is installed in the housing 1, the second side glass 33 and the third side glass 34 are squeezed and displaced along the length direction of the mounting frame 2, which cannot avoid the second side glass 33 and the third side glass 34 from colliding and being damaged. Therefore, the first groove portion 2212 and the second groove portion 2213 reserve a reserved gap L in the length direction of the mounting frame 2 for the second side glass 33 and the third side glass 34 to adjust their positions. Because the cable 36 is a COF connecting wire with a metal layer, the bending rebound force of the cable 36 is related to its bending radius, and the reserved gap L is designed to fine-tune the bending radius. In this embodiment, the value of the reserved gap L is designed to be 3.5-5mm. In a preferred example, the design value of the reserved gap L is 5mm; in an optional example, the value of the reserved gap L is 3.5mm.

When the front frame 11 is covered, the downward pressure causes the display module 3 to be displaced, and the flat cable 36 is squeezed and deformed. To prevent the flat cable 36 from contacting the inner wall of the housing 1, it is necessary to consider the gap value M between the left and right sides of the installation frame 2 and the inner wall of the bottom housing 12, as well as the gap value m between the flat cable 36 and the inner wall of the bottom housing 12 after being installed in the housing 1. Specifically, in an optional embodiment, the value of M is 5 mm, and the value of m should be greater than 1 mm.

Since the flat cable 36 has the ability to rebound, when the second side glass 33 and the third side glass 34 are not fixed by the pressing piece 4 (unlocked state), due to the influence of gravity, the display panel 31 and the first mounting surface 211 are in contact state, as shown in FIG7 ; when the pressing piece 4 fixes the second side glass 33 and the third side glass 34 (locked state), the rebound force of the flat cable 36 will lift the display panel 31, so that there is a gap between the display panel 31 and the first mounting surface 211, as shown in FIG8 and FIG9 ; when the mounting frame 2 is installed in the bottom shell 12 and the front frame 11 is modified, the squeezed and lifted display panel 31 will be pressed down, so that the display panel 31 is tightly attached to the front frame 11 by relying on the rebound force of the flat cable 36 to achieve the purpose of optimal display.

The display device provided by the embodiment of the utility model is designed with a double-layer installation frame, so that the side glasses of the display module can be installed in layers without interfering with each other, thereby avoiding the problem of being unable to be fixed due to the unified back-mounted devices occupying each other's space, achieving a smaller installation space while satisfying the lightweight design, and can be easily and quickly disassembled and assembled to achieve a quick screen change effect, greatly improving convenience; in addition, combined with the characteristics of the COF cable, the installation gap is reasonably designed to achieve the best display effect.

Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
