3 is an exploded perspective view of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 3, mounting holes 103 and 104 are formed in the front case 101, and a display module 151a and a first operation unit 131 are mounted in the mounting holes 103 and 104.

In the front case 101, a window 200 covering the display module 151a is mounted. The upper surface of the front case 101 forms an attachment surface for attaching the window 200 and the window 200 can be attached to the attachment surface by an adhesive or an adhesive film.

At least part of the window 200 is formed of a light-transmitting material so that the visual information output from the display module 151a can be seen. According to this embodiment, the transmissive region 201 and the opaque region 202 are formed in the window 200.

To this end, the window 200 includes a touch sensor for sensing a touch. The following description will be made based on the configuration of a 'touch window' capable of sensing a touch, but the present invention is also applicable to a window without a touch sensor.

FIG. 4 is an exploded perspective view of the window shown in FIG. 3, and FIG. 5 is a sectional view of the mobile terminal according to the line V-V in FIG.

The window 200 related to the present invention includes an upper layer 210 and a lower layer 220.

The upper layer 210 is formed of a transparent glass material. The upper layer 210 is preferably made of tempered glass reinforced to enhance rigidity. By forming the outer surface of the window 200 from the tempered glass, the appearance of the window 200 can be improved and the strength of the window 200 can be improved. In addition, it is possible to prevent deformation of the window 200 due to repeated touch operations, thereby improving the reliability of the touch operation.

The lower layer 220 is attached to the lower surface of the upper layer 210 and has a shape in which the upper layer 210 extends from the periphery. The lower layer 220 is configured to be hung on a terminal body, specifically, a part of the front case 101.

The upper layer 210 and the lower layer 220 may each have a rectangular sheet shape as shown in FIG. 4. In this case, the lower layer 220 has a larger area than the upper layer 210.

The upper layer and the lower layer 220 are attached to each other to form a stepped shape at the outer portion of the window 200 as shown in FIG. The upper layer 210 and the lower layer 220 may be attached to each other by a transparent adhesive or an adhesive film.

The lower layer 220 may be formed of glass or a tempered glass such as the upper layer 210. In addition, the lower layer 220 may be formed of a material other than the upper layer 210, for example, a transparent synthetic resin material. The manufacturing cost of the window 200 can be reduced by using a synthetic resin which is relatively inexpensive as the lower layer 220.

The touch sensor provided in the window 200 may be implemented as a transparent touch film 230 as shown in FIG. A transparent conductive pattern is formed on the touch film 230, and a conductive pattern generates an electrical signal when a touch is applied to the window 200. According to this embodiment, the touch film 230 is attached to the lower surface of the lower layer 220, but it is also possible that the touch film 230 is attached between the upper layer 210 and the lower layer 220 . The touch film 230 may also be attached to the lower layer 220 by a transparent adhesive film or adhesive. The touch film 230 may be provided with a connector for connection with the printed circuit board 105 (see FIG. 5) inside the terminal body.

Mounting holes 231a to 231c for mounting the first operation unit 131 may be formed on the upper and lower layers 210 and 220 and the touch film 230.

5 shows a state where a window is mounted on a terminal body.

5, a printed circuit board 105 and a display module 151a are disposed between the front case 101 and the rear case 102, and a window 200 is disposed on the upper part of the display, .

The lower surface of the lower layer 220 is attached to the mounting surface S formed on the front case 101 by the adhesive film 240. [ However, since the lower layer 220 of the window 200 is fixed to a part of the front case 101, the adhesive film 240 may be omitted.

On the other hand, a cover 107 may be coupled to the front case 101 to form a part of the front case 101. The cover 107 may have a shape corresponding to the outline of the window 200 and a through hole 108 corresponding to the area of the upper layer 210 of the window 200 may be formed at the center of the cover 107 .

The lower layer 220 is caught by the cover 107 when the cover 107 is engaged with the front case 101. [ That is, the upper surface of the lower layer 220 extending around the upper layer 210 is caught by the lower surface of the cover 107. The upper razor 210 is located in the through hole 108 of the cover 107 and coplanar with the cover 107.

The cover 107 is integrally formed with the front case 101 so that a part of the front case 101 is connected to the front case 101 It is also possible to achieve.

The adhesive film 240 is first attached to the mounting surface S of the front case 101 and the adhesive film 240 is attached to the front surface of the window 200. [ The lower layer 220 is attached. When the cover 107 is coupled to the front case 101 so that the lower layer 220 is caught by the cover 107, the assembling process of the window 200 and the front case 101 is completed.

However, when the mounting surface S is not formed on the front case 101, it is also possible to assemble the window 200 in the direction of the back surface of the cover 107 to catch the lower layer 220 on the cover 107 I will do it.

As described above, the structure in which the stepped structure of the window 200 is hung on a part of the terminal body can prevent the window 200 from being detached or lifted to the outside of the terminal body. In addition, the stepped structure of the window 200 also prevents moisture from flowing into the inside of the terminal body. In addition, it is possible to increase the area of the window 200 attached to the mounting surface S, and consequently to reduce the width W of the rim of the terminal body.

However, when the window 200 is formed of glass or tempered glass, step formation through CNC machining is required to form the stepped structure of the window 200. [ Since the glass has a strong brittleness property, a minute crack is generated in the window 200 when the glass window 200 is stepped, thereby causing the rigidity of the window 200 to deteriorate.

The present invention implements a step structure of the window 200 as two layers 210 and 220 to prevent the rigidity deterioration of the window 200 described above.

When both the upper layer 210 and the lower layer 220 are made of tempered glass, stable quality can be achieved without decreasing the rigidity of the window 200. In addition, when the upper layer 210 is used as a tempered glass and the lower layer 220 is used as a synthetic resin material, it is possible to realize an inexpensive window 200 while taking advantage of tempered glass.

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
