Description
Technical field
The present invention relates to display technology field, more particularly to a kind of LCDs, display device and its improvement display are not
Good method.
Background technology
People are not strange for touching technique, and bank is designed with the cash dispenser of touch function, hospital, library etc. mostly
Hall have the computer of touch function.In addition, supporting that mobile phone, MP3, the digital camera of touch-screen also more come much at present.Fig. 1
Be the structural representation of existing display device, as shown in figure 1, it is seen that display device including upper strata touch-screen 1, under
The liquid crystal display of layer（LCD, Liquid Crystal Display）Screen 2；Wherein, the touch-screen 1 plays sensor, is
One transparent glass substrate with touch-responsive surface, the touch-screen 1 is generally placed above the LCD screen 2, makes
The touch area of the panel of the touch-screen 1 can cover the viewing area of the LCD screen 2；LCD screen 2 includes upper substrate 21, lower base
Plate 22, upper substrate 21, infrabasal plate 22 pass through supporter（PS）23 connections, the height that supporter 23 separates upper substrate, infrabasal plate
As box is thick（Cell Gap）；Liquid crystal and vertical and level is provided between upper substrate 21, the infrabasal plate 22 of LCD screen 2
Tiny electric wire, change direction come liquid crystal molecule by whether being powered, and light is reflected into generation picture.
Fig. 2 is a kind of composition structural representation of LCD screen in the prior art, as shown in Fig. 2 LCD screen include upper substrate, under
The supporter of substrate and support upper substrate and infrabasal plate（PS）23, be for the height that upper substrate, infrabasal plate separate by supporter 23
Box is thick；Wherein, the upper substrate includes upper polarizer 201, top glass substrate 202, black matrix 203, colored pixels 204, public
