The LCD panel 211 is composed of a color filter for outputting red, green and blue, a liquid crystal and a thin film transistor (TFT), and outputs various images by applying a signal to the color filter.

The touch panel 212 has a structure in which a film (ITO film) including a transparent electrode pattern made of a transparent material is located at a portion corresponding to the display portion, As shown in FIG. The touch panel can be in the form of film or sheet.

The touch panel 212 may be integrated with the front window layer 220 by stacking the transparent electrode pattern of the touch panel 212 on the window layer 220 as shown in FIG. In addition, the touch panel 212 and the LCD panel 211 may be coupled using a transparent adhesive so as not to separate them.

That is, a hybrid type member in which the window layer 220, the touch panel 212, and the LCD panel 211 are integrally formed can be used.

As another example of the touch screen 210, an in-cell type touch screen 210 implemented in the LCD panel 211 may be used as the touch panel 212. The touch screen of the in-cell type does not need to laminate a separate touch panel 2) on the LCD panel 211 because the transparent electrode pattern of the touch panel is added to the LCD panel for image output.

The total thickness of the LCD panel 211 and the touch panel 212 is reduced by using the touch panel of the in-cell type and the contrast ratio generated by the touch panel 212, which is further stacked on the LCD panel 211, And the increase of the luminance reduction surface reflection are solved, and the original characteristics of the LCD panel can be maintained.

In any case, since the LCD panel has a touch function, an opaque data pattern formed around the touch panel 212 formed separately from the LCD panel 211 becomes unnecessary.

And a back light unit 215 coupled to the rear surface of the LCD panel 211 to supply light to the LCD panel 211. [ The rear dimming device 215 is a device for producing a flat light having uniform brightness from a fluorescent lamp serving as a light source. The rear dimming device 215 has a light source for supplying light to the side surface, and uses light guide plates, diffusion sheets, And supplies light to the LCD panel 211.

The screen holder 235 is coupled at the side of the LCD panel 211 and the rear dimming device 215 to fasten the LCD panel 211 and the rear dimming device 215 so as not to separate them, And shields light emitted from the LCD panel 211 from being emitted to a portion other than the LCD panel 211.

The screen holder 235 can be manufactured by injection molding with plastic or the like and can be made of a material that is strong against impacts as compared with the touch screen 210 or the window layer 220.

The screen holder 235 may completely cover the side surface of the LCD panel 211, but may cover only partly as shown in FIG. 6, or may be coupled around the bottom surface of the LCD panel 211. The screen holder 235 includes an outer holder portion that extends outwardly from the LCD panel 211.

Further, it may further include a shielding film between the screen holder 235 and the LCD panel 211 to prevent light from leaking out from the rear light control device 215.

The window layer 220 is coupled to the front surface of the touch screen 210 and includes a light emitting unit corresponding to an area for displaying and touching the touch screen 210 And a bezel 223 printed with an opaque material covering its periphery.

The bezel 223 covers the display area 221 of the touch screen 210 on the front side and the touch panel 212 is provided with a data pattern and a case 101 such as a camera module 121 and a sound module 152 ) Is made of an opaque material so that the electronic parts mounted inside the electronic parts can not be seen by the user.

However, the larger the bezel 223, the smaller the size of the bezel 223 because the display area 221 is reduced in the same size mobile terminal.

The structure of the conventional mobile terminal shown in FIG. 7 is a structure in which the window layer 30, the touch panel 20, and the LCD panel 10 are laminated. In this structure, the window layer 30 is formed larger than the touch panel 20 and the LCD panel 10 and is joined at the front face of the case 1, and the periphery of the window layer 30 and the through- And the front surface of the window is joined by the adhesive tape 40. Fig.

In this structure, the bezel 35 of the window layer 30 needs to be wide enough to cover the data pattern of the touch panel 20 and the adhesive tape 40. The width of the adhesive tape 40 is about 0.8 to 1 mm, and the width of the data pattern of the touch panel is about 1.3 to 1.5 mm. Accordingly, in the structure in which the window layer 30 is coupled to the front surface of the case 1 as in the conventional art, the left and right bezel 35 occupies about 2.1 to 2.5 mm.

However, in the present invention, the window layer 220 is inserted into the opening rather than the front surface of the case 101, and the inner circumference of the through-hole 101a is formed in the outer periphery of the screen holder 235 And is in contact with the upper surface of the holder portion.

At this time, the window layer 220 is bonded to the touch screen 210 with a transparent adhesive so that the window layer 220 and the touch screen 210 can be integrated. The window layer 220 can be lifted or removed even if it is not attached to the case 101 with adhesive tape on the left and right sides of the window layer 220 because the structure is such that the screen holder 235 is caught around the through- And is not separated from the case 101.

The window layer 220 and the touch screen 210 are made of fragile components and may be damaged if an external impact is applied to the mobile terminal, It is preferable to be coupled to the holder 235.

However, since the screen holder 235 can be separated by the impact, the elastic portion 101b is formed at the inner circumference of the through-hole 101a of the case 101, that is, at the portion in contact with the screen holder 235, ). The elastic portion 101b absorbs an external impact and can prevent the screen holder 235 from being broken or the screen holder 235 from being separated from the touch screen 210 or the rear light control device 215. [

Since the adhesive tape 40 is not required in the conventional structure, the left and right bezels 223 only cover the data lines of the touch panel 220, so that the width B thereof is in the range of about 1.3 to 1.5 mm . The size of the left and right bezels 223 can be reduced by about 1 mm compared to the conventional case.

 The frame 210 may further include a frame 250 for supporting the touch screen 210 and the rear light control device 215 on the rear surface so that the touch screen 210 and the rear light control device 215 can closely contact with the front through- .

The frame 250 is coupled with the case 101 to securely fix the touch screen 210 on the front surface of the case 101. As the material of the frame 250, various materials such as a metal material and a reinforced plastic can be used.

An adhesive or an adhesive tape 237 may be used between the frame 250 and the screen holder 235 to fix the screen holder 235 to the frame 250.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Accordingly, the above description should not be construed in a limiting sense in all respects 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.
