As shown in Figure 1-Figure 3, the utility model embodiment provides a kind of touch controlled type liquid crystal display die set, for mobile phone,
The electronic equipments such as IPAD, notebook, the touch controlled type liquid crystal display die set include the touch-control lid of the setting of stacking fitting from top to bottom
Plate 100, liquid crystal display 200 and backlight 300 wherein pass through OCA optics between touch cover 100 and liquid crystal display 200
Glue 400 is adhesively fixed.The touch cover 100 is that touch screen is integrated with cover sheet, and one side is played to liquid crystal
The protective effect of display screen 200, on the one hand makes display module have touch function, and backlight 300 is used to mention for liquid crystal display 200
For backlight light, liquid crystal display 200 is enable to show required pattern when needing to show.
In the utility model, the liquid crystal display 200 includes the lower sheet glass 210 and upper sheet glass of opposite fitting setting
220.The relatively upper sheet glass 220 in the side of the lower sheet glass 210 extends outward an extension 211, the extension 211
Upper surface binding has driving IC500 and flexible circuit board 600, the bent master extended to display module of flexible circuit board 600
Plate connection, for realizing crystal display.
Since driving IC500 and flexible circuit board 600 only take up the partial region of extension 211, lower sheet glass 210 is prominent
Extension 211 it is very fragile in the region of not set driving IC500 and flexible circuit board 600, the especially side of extension 211
Angle Position easily causes the fragmentation of extension 211 when display module is fallen and causes display abnormal, therefore the utility model
It proposes that resilient mat layer is arranged in the upper surface of the extension 211, which avoids driving IC500 and soft route
