Electrochromic photosensitive display screen

Abstract

The invention relates to an electrochromic photosensitive display screen. At present, an LCD (liquid crystal display) screen reaches the large-scale commercialized production level, however, the disadvantages of higher manufacturing cost, smaller visual angle, lower response speed, liquid crystal dead pixels, low brightness and contrast ratio and the like are urgent to be improved in the current LCD technology. The electrochromic photosensitive display screen comprises a display screen, wherein integral development is realized in the display screen by the aid of multiple pixel points; the electrochromic photosensitive display screen is characterized in that the pixel points are made of red, green and blue electrochromic materials, and the depth of the three colors is regulated according to different driving voltage. The integral display performance of the electrochromic display screen can be improved, the electrochromic screen can have the self-photosensitive effect, then photoluminescence of an outer light source or the electrochromic materials is driven to be stronger, and the purpose of screen brightness change is achieved.

Description

technical field [0001] The invention relates to an electrochromic photosensitive display screen. Background technique [0002] Today, LCD display screens have reached the level of large-scale commercial production, and LCD display technology is relatively mature. However, the shortcomings of high cost, small viewing angle, slow response speed, dead pixels of liquid crystal, low brightness and contrast are also the current LCD display technology that needs to be improved and improved urgently. At the same time, since Deb discovered amorphous WO in 1969 3 Since (tungsten trioxide) has electrochromic properties, the discovery and development of various organic and inorganic color-changing materials have been extensively studied by researchers. The manufacturing process of the electrochromic device (ECD) made of it is also becoming more and more mature, and its main application fields include: display screens, smart windows, anti-glare mirrors, color-changing goggles, etc. Ho...

AI Technical Summary

Problems solved by technology

However, defects such as slow response speed, frequent discoloration, high power consumption, and low display life are also the main problems of electrochromic devices.

[0003] Due to the shortcomings of electrochromic materials such as slow response speed, frequent discoloration, high power consumption, and low display life, it is difficult to develop in the field of display that requires a high number of frames (such as: mobile phone screens, computer and TV monitors, etc.)

On the other hand, because the electrochromic material does not rely on the backlight to provide light, the improvement of screen brightness is often a problem that needs to be solved.
