Problems solved by technology

In the prior art, the upper polarizers of liquid crystal displays and OLED displays need to be pasted separately, and special high-precision laminating equipment and skilled operators need to be invested; and after the upper polarizers of liquid crystal displays and OLED displays are bonded to the touch screen Due to the different expansion and contraction coefficients, it is easy to cause the phenomenon of moiré (mura)
In addition, the angle between the absorption axes of the upper and lower polarizers of the liquid crystal display is difficult to guarantee due to the problem of alignment accuracy; and the light transmission loss between the multi-layer films is relatively large, which is not conducive to the improvement of the brightness of the display module

Abstract

The invention provides a touch screen with a polarization function. The touch screen comprises a transparent cover plate, a first transparent conducting layer and a first polarization layer which are sequentially stacked from top to bottom, wherein the first transparent conducting layer is formed on the first polarization layer in a coating or transfer printing mode, and the transparent cover plate is formed on the first transparent conducting layer with a binding agent in a binding mode. The invention further provides a display device. According to the display device and the touch screen thereof, the touch screen has the function of generating polarized light, after the touch screen is used, it is not needed to extra arrange an upper polarization sheet on an existing liquid crystal display and an OLED displayer, and therefore the display device can be thinned; meanwhile, the structure of the display device can be simplified, cost of the display device is reduced, and performance of the display device is improved.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a touch screen thereof. Background technique [0002] Common displays currently on the market include liquid crystal displays (LCD) and organic light emitting diode (OLED) displays. A liquid crystal display (LCD) includes a touch screen, an upper polarizer, an LCD, a lower polarizer, and a backlight module; an OLED display includes a touch screen, an upper polarizer and an OLED. In the prior art, the upper polarizers of the liquid crystal display and the OLED display need to be attached separately, and special high-precision laminating equipment and skilled operators are required; and the polarizers of the liquid crystal display and the OLED display are bonded with the touch screen. Due to the different coefficients of expansion and contraction, it is easy to cause the phenomenon of mura. In addition, the included angle of the absorption axis after the ...
