Abstract
The utility model relates to a touch-sensitive LCD device, which comprises a superposition-set LCD panel and a touch-sensitive screen. The touch-sensitive screen is composed of a support layer and an electrode layer superposition-set, wherein the support layer is close to the LCD panel, and the surface of the support layer close to the LCD panel is provided with a light scattering structure. The light scattering structure scatters the light emitted from the LCD panel to the support layer, which avoids the light interference phenomenon and then improves and enhances the picture display quality of the LCD device.

Technical field
The utility model is about a kind of touch control type LCD device.
Background technology
In recent years, touch-screen is widely used in the various electronic products such as mobile phone, computer as a kind of information input tool of electronic product, and becomes the widely used information input tool of people after mouse and keyboard gradually.
Seeing also Fig. 1, is a kind of side view of prior art touch control type LCD device.This touch control type LCD device 1 comprises a touch-screen 11, a display panels 13 and the group 14 of touching backlight of stacked setting.This group 14 of touching backlight provides uniform in-plane light for this display panels 13.
This touch-screen 11 comprises a transparent resin layer 113, a top electrode 114, a bottom electrode 115 and a supporting layer 116 of stacked setting from top to bottom.The lower surface edge of this supporting layer 116 is provided with colloid 117.This supporting layer 114 is a glass plate.
This display panels 13 comprise stacked setting from top to bottom one on polaroid 131, a upper glass plates 132, a liquid crystal layer 133, a lower glass plate 134 and polaroid 135 once.This touch-screen 11 is attached at last polaroid 131 1 sides of this display panels 13 by this colloid 117.
Yet, paste by this colloid 117 between the supporting layer 116 of this touch-screen 11 and this display panels 13 and is connected, there is an air layer (sign) between the two.This taping process still is that the board operation all is difficult to guarantee this display panels 13 and these touch-screen 11 absolute parallel by manually-operated.Because glass is optically denser medium, air is an optically thinner medium, organize 14 light that send via the air (optically thinner medium) between this display panels 13 (optically denser medium) directive itself and this supporting layer 116 by this backlight touching, this supporting layer 116 (optically denser medium) of directive again, the reflection and the refraction of several times can take place at this display panels 13 and these supporting layer 116 the two adjacently situated surfaces in light, form interference fringe.This interference fringe has a strong impact on the picture display quality of this touch control type LCD device 1.
The utility model content
Interference fringe influences the problem that picture shows in the prior art touch control type LCD device in order to solve, and is necessary to provide a kind of display quality touch control type LCD device preferably.
A kind of touch control type LCD device, it comprises a display panels and a touch-screen of stacked setting.This touch-screen comprises a supporting layer and an electrode layer of stacked setting, contiguous this display panels of this supporting layer, and the surface of its contiguous this display panels is provided with light scattering structure.
Compared with prior art, the surface of the contiguous display panel of the supporting layer of the touch-screen of the utility model touch control type LCD device is provided with light scattering structure, this light scattering structure can will be broken up by the light of display panels directive supporting layer, prevent that it from producing the interference of light phenomenon, improves and improve the picture display quality of this touch control type LCD device.
