The mobile terminal 100 is provided with a touch sensor to provide a simpler appearance and a convenient user interface. Hereinafter, the structure and manufacturing method of the display module 110 including the touch sensor will be described in more detail.

3 is an exploded perspective view of the mobile terminal 100 of FIG. 1 and shows a configuration of the display module 110.

Referring to FIG. 3, a circuit board 180 is disposed in the terminal body. The circuit board 180 may be mounted on the rear case 102 as shown, or may be mounted on a separate internal structure. The circuit board 180 may be configured as an example of a controller for operating various functions of the mobile terminal 100.

The display module 110 electrically connected to the circuit board 180 is disposed on one surface of the circuit board 180. The display module 110 includes a window 111 and a display 112 disposed on a rear surface of the window 151 to output visual information. In this figure, the window 111 and the display 112 are shown separately for convenience of understanding.

The front case 101 is provided with a seating portion 101a recessed from one surface so that a part of the window portion 111 may be seated. Unlike the present example, the seating portion 101a may be provided separately from the front case 101.

The seating portion 101a is provided with a hole 121a corresponding to the first camera portion 121 and an acoustic hole 151a corresponding to the first sound output unit 151. The sound hole 151a may be disposed adjacent to the sidewall of the front case 101. A through hole 181a through which the flexible circuit board 181 can pass is formed in the seating portion 101a. The through hole 181a may be formed on the bottom surface or the side surface of the seating portion 101a.

4 is a cross-sectional view of the display module 110 shown in FIG. 3 taken along the line IV-IV.

Referring to FIG. 4 together with FIG. 3, the display module 110 includes a window 111 and a display 112 disposed on a rear surface of the window 111 to output visual information. The window 111 includes first and second windows 111a and 111b.

The first window 111a is formed of a material through which light can pass, for example, a transparent synthetic resin, tempered glass, or the like. As shown in FIG. 3, the first window 111a may occupy most of the front surface of the terminal body.

The first window 111a may be divided into a central region C corresponding to the display 111 (specifically, the region where visual information is actually output) and an edge region S surrounding the central region C. FIG. have. The central area C is preferably colorless and transparent so that visual information output from the display 112 can be recognized from the outside, and the edge area S is colored so that the mechanism structure inside the terminal body is not exposed to the outside. And / or opaque.

The edge area S is formed except for portions corresponding to the holes 121a and the first manipulation unit 131, and forms specific symbols representing the transmissive image window 121b and the first manipulation unit 131, respectively. can do.

In addition, a groove 151b may be formed on a side surface of the first window 111a disposed to face the sidewall of the front case 101 to form an assembly gap. According to the above structure, the sound generated from the first sound output unit 151 is discharged along the assembly gap between the front case 101 and the groove 151b, and moves independently because the holes formed independently for the sound output are not visible. The appearance of the terminal 100 may be simpler.

A touch pattern part 113 forming a sensing channel of a touch input with respect to the center area C is formed on the rear surface of the first window 111a. The touch pattern unit 113 may be implemented in a form in which a transparent electrode such as indium tin oxide (ITO), carbon nanotubes (CNT), graphene, or the like is deposited on a window.

The touch pattern unit 113 may include first and second pattern layers formed of a predetermined pattern in the central area C. FIG. In this figure, the first and second pattern layers are conceptually illustrated as one pattern layer in order to easily explain the connection relationship between the touch pattern unit 113 and the signal transmission unit 114.

The first pattern layer is formed to extend in a first direction (eg, the width direction of the window 111), and the second pattern layer is formed in a second direction perpendicular to the first direction (eg, the window portion). It is formed to extend along the longitudinal direction of the (111) may form a sensing channel with the first pattern layer.

The predetermined pattern may be implemented in various forms such as a diamond shape, a circle, and a zigzag pattern. An insulating part may be disposed between the first pattern layer and the second pattern layer to electrically insulate the first pattern layer from the second pattern layer. For example, the insulating part may be formed in the form of a bridge crossing the first pattern layer, and the second pattern layer may be disposed to cover the insulating part.

The touch pattern unit 113 detects a change in the amount of charge in the first and second directions through the first and second pattern layers. The touch pattern unit 113 is electrically connected to the circuit board 180 having a detector (not shown) through a connection structure that is connected to the signal transmission unit 114, the conductive unit 118, and the flexible circuit board 181. do. The detector detects a touch input by using a change in the amount of charge detected in each of the first and second pattern layers.

For example, when a conductor such as a finger or a touch pen touches the first window 111a, electrons in the first window 111a move to the conductor, and the detector detects the touch pattern 113. The coordinates are measured using the change in the amount of charge. The detector may be configured to detect not only a position and an area touched by the first window 111a but also a pressure at the touch.

A signal transmission unit 114 is formed at a portion corresponding to the edge region S of the first window 111a to be electrically connected to the touch pattern unit 113 to form a signal transmission path. The signal transfer unit 114 may be understood as a routing electrode that electrically connects the touch pattern unit 113 and the flexible circuit board 181. The signal transmission unit 114 may be implemented in a form in which electrodes of a metal material (eg, Mo / Al / Mo, Mo / Ag / Mo, etc.) are deposited on a window. In this case, the signal transmission unit 114 may be formed to cover at least a portion of the touch pattern unit 113 to form an electrical connection with the touch pattern unit 113.

The second window 111b is coupled to the first window 111a so as to cover the signal transmission unit 114 and protects the signal transmission unit 114. The second window 111b is formed of a material through which light can pass, such as the first window 111a, for example, a transparent synthetic resin, tempered glass, and the like. In this case, it is preferable that the first and second windows 111a and 111b are formed of the same refractive index material so as not to reduce visibility. For example, when the first and second windows 111a and 111b are formed of the same tempered glass, the visual information output from the display 112 may be displayed to the user with a minimized distortion due to the refractive index difference. .

The second window 111b may be formed to have a thickness thinner than that of the first window 111a through post-processing. For example, the second window 111b may be coupled to the first window 111a and then processed into a thinner plate shape through NC (Numerical Control) cutting or chemical etching.

An adhesive layer 115 is disposed between the first and second windows 111a and 111b therebetween. The adhesive layer 115 may be a film type OCA (Optically Clear Adhesive) or a liquid type OCR (Optically Clear Resin). The first and second windows 111a and 111b are integrally coupled by the adhesive layer 115 to form the window 111.

The adhesive layer 115 is formed of a light-transmissive material, and is preferably disposed to cover the central region C to improve visibility of visual information output from the display 112. That is, by filling the adhesive layer 115, not the air layer, between the first window 111a and the second window 111b, deterioration of sharpness due to scattering of light and loss of transmittance may be prevented.

The display 112 may be coupled to the rear surface of the second window 111b to form the display module 110. To this end, a bonding layer 116 is disposed between the display 112 and the second window 111b. The bonding layer 116 has the same or similar structure and function as the adhesive layer 115 described above. In other words, the bonding layer 116 is formed of a light-transmissive material, and is preferably disposed to cover a portion corresponding to the center area C to improve visibility of visual information output from the display 112.

According to the above structure, since the first window 111a, the second window 111b, and the display 112 are integrally combined and there is no air layer therebetween, the visibility can be improved and the thickness thereof is reduced. Due to this, a slimmer mobile terminal 100 may be implemented.

The second window 111b is supported by the seating portion 101a. Specifically, the seating portion 101a accommodates the display 112 and forms a space such that at least a portion of the second window 111b corresponding to the edge area S is seated. In this case, at least a part of the signal transmission unit 114 may be disposed to overlap the seating portion 101a in the thickness direction of the first window 111a.

According to the above structure, when an impact is applied from the outside, the second window 111b serves to buffer the shock transmitted from the front case 101 to the signal transmission unit 114, thereby preventing the transmission of the signal transmission unit 114. Prevent damage. In addition, since the signal transmission unit 114 is disposed to overlap the seating unit 101a, the width of the edge area S, that is, the bezel may be reduced.

FIG. 5 is a rear view of the display module 110 of FIG. 4, and FIG. 6 is an enlarged conceptual view of a portion A shown in FIG. 5.

The second window 111b may be formed to have a smaller size than the first window 111a in consideration of assembly tolerances. For example, as shown in FIG. 5, the first window 111a may be formed to protrude beyond the edge of the second window 111b. Of course, after the second window 111b is coupled to the first window 111a and undergoes post-processing to remove the edge portion, the first and second windows 111a and 111b may be formed in the same size.

The signal transmission unit 114 is electrically connected to a control unit (specifically, the detection unit described above) through the flexible circuit board 181. Referring to FIG. 6, a cutout 111b ′ is formed in the second window 111b to avoid interference with a portion to which the flexible circuit board 181 is connected.

The terminal 114a of the signal transfer unit 114 exposed through the cutout 111b 'is electrically connected to the flexible circuit board 181 through the conductive unit 118. The conductive part 118 may be implemented in the form of an anisotropic conductive film (ACF) or an anisotropic conductive paste (ACP). The anisotropic conductive film and the anisotropic conductive paste include conductive particles in an adhesive component, and electrically connect the signal transmission unit 114 and the flexible circuit board 181.

7 and 8 are conceptual views illustrating modified examples of the display modules 210 and 310.

Referring to FIG. 7, a recess 211b ′ is formed at a portion of the second window 211b that faces the signal transfer unit 214. The recess 211b ′ is an empty space in a design for avoiding direct contact between the second window 211b and the signal transmission unit 214. The recess 211b ′ may be formed to extend along the signal transfer unit 214 and may form a loop shape as a whole.

The space between the signal transmission part 214 and the recess part 211b 'may be left empty or filled by the adhesive layer 215. In particular, in the latter case, since the adhesive layer 215 has a larger modulus of elasticity than the second window 211b, when the shock is transmitted to the second window 211b, the adhesive layer 215 absorbs the shock and is transmitted to the signal transmission unit 214. Reduce the impact

Referring to FIG. 8, a hole 311b ′ is formed in the second window 311b to expose the terminal 314a of the signal transmission unit 314, and the conductive portion 318 is formed in the hole 311b ′. Is charged. The conductive portion 318 may be the anisotropic conductive paste described above. The flexible circuit board 381 is attached to the rear surface of the second window 311b so as to cover the hole 311b ', and is configured to detect a touch input by using a change in the amount of charge detected by the touch pattern unit 313 (specifically). To be electrically connected to the detector described above.

9 is a process diagram showing an example of a manufacturing method of a mobile terminal 100 according to the present invention.

Referring to FIG. 9, first, the edge region S of the first window 111a is opaquely partitioned into a central region C that transmits light, and an edge region S surrounding the light transmissive region. For example, an opaque material may be printed or deposited on the rear surface of the first window 111a except for the central region C to form the central region C and the edge region S. FIG.

Thereafter, an electrode forming a signal transmission path for the touch input is formed. For example, after the touch pattern portion 113 is deposited in a specific pattern in the center region C, the signal transmission unit 114 forming the wiring of the touch pattern portion 113 is deposited in the edge region S. Referring to FIG. In this case, the signal transmission unit 114 may be formed to cover at least a portion of the touch pattern unit 113 to form an electrical connection with the touch pattern unit 113.

Next, the second window 111b is laminated on the rear surface of the first window 111a to cover and protect the electrode. For example, after applying the liquid adhesive layer 115 to the front of the second window (111b) facing the first window (111a), attaching the second window (111b) to the back of the first window (111a). And press to integrate them. At this time, the adhesive layer 115 is preferably applied only to the central region (C) so that the adhesive layer 115 does not leak when pressed.

Referring to FIG. 6 together, the cutout 111b 'may be formed in advance in the second window 111b in consideration of the time when the second window 111b is coupled to the first window 111a. That is, a portion of the second window 111b corresponding to the terminal 114a of the signal transmission unit 114 is cut out so that the terminal 114a is coupled when the second window 111b is coupled to the first window 111a. It is made to be exposed through the cutout (111b ').

When the second window 111b is coupled to the first window 111a, the thickness of the window 111 is reduced by polishing the second window 111b. Specifically, the second window 111b may be processed into a thin plate shape (for example, about 0.2 mm) by removing the rear surface through NC cutting or chemical etching.

After the second window 111b is processed to an appropriate thickness, an anisotropic conductive film is attached or anisotropic conductive paste is applied on the terminal 114a exposed through the cutout 111b ', and the flexible circuit board 181 is disposed. Attach. In this case, the cutout 111b ′ is formed to accommodate the flexible circuit board 181 and surround at least a portion thereof.

Thereafter, the display 112 is laminated on the rear surface of the second window 111b to form the display module 110 in which the window 111 and the display 112 are coupled. For example, after the light-transmissive bonding layer 116 is applied to the front surface of the display 112, the display 112 is attached and pressed to correspond to the central region C to be integrated.

When the display module 110 is completed, the display module 110 is coupled to the front case 101. A liquid or film adhesive material 117 is coated or disposed on the seating portion 101a on which the second window 111b is seated so that the second window 111b can be firmly coupled to the seating portion 101a. . The adhesive material 117 is preferably formed to allow a predetermined elastic deformation so as to reduce the shock transmitted to the second window 111b.
