AI Technical Summary

Problems solved by technology

by figure 1 The touch display device shown is taken as an example. In practical applications, the sum of light reflectance of such a display device is about 10%, and the display brightness of the display device itself is usually 200-400 nit. When the ambient brightness is about 20000nit, the brightness of the reflected light of the display device will reach 2000nit. It can be seen that the intensity of the reflected light is much higher than the intensity of the display light of the display device itself, which will cause the touch-sensitive display device to Poor display in light environments
[0004] At present, the commonly used method is to attach a layer of high-transmittance anti-reflection film on the upper surface of the touch panel. This film can reduce the surface reflectance of the display device to a certain extent, but it is still difficult to improve the overall high light emission of the display device. reflection

Abstract

The embodiment of the invention provides a display device and a manufacturing method thereof, relating to the field of display techniques. The display device can reduce surface reflection of a medium layer and improve display effects of the display device. The display device comprises a display panel and a function screen located at a visual side of the display panel, wherein the medium layer is arranged between the display panel and the function screen; an oblong light polarizing sheet or a round light polarizing sheet is arranged on the surface of the function screen; and the oblong light polarizing sheet or the round light polarizing sheet includes a wave plate and a light polarization film layer. The embodiment of the invention is used for producing the display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] With the continuous development of display technology, display devices with functional screens, such as display devices with touch functions, have been favored by more and more people due to their easy operation and intuitive features, and have gradually become the market mainstream. [0003] The structure of the currently common touch display device can be as follows: figure 1 As shown, the touch display device 10 mainly includes a display panel 11 for display and a touch screen 13 for realizing the touch function. In the existing manufacturing process, the display panel 11 and the An air medium layer 12 inevitably appears between the touch screens 13 . When the user uses such a touch-sensitive display device outdoors, since the interface between the air dielectric layer 12 and the display panel 11 and the touch screen ...
