Reflecting type electrochromic liquid crystal display (LCD)

Abstract

The invention discloses a reflecting type electrochromic liquid crystal display (LCD) which comprises a first base plate, a second base plate, a first electrochromic liquid crystal mixture layer, a first electrode layer and a second electrode layer, wherein the second base plate is parallel to the first base plate, and the first electrochromic liquid crystal mixture layer is configured between the first base plate and the second base plate and comprises a plurality of liquid crystal molecules, an optical rotating agent and a macromolecule mixture; the liquid crystal molecules and the optical rotating agent are distributed in a curing structure of the macromolecule mixture; the first electrode layer is configured between the first base plate and the first electrochromic liquid crystal mixture layer, and the second electrode layer is configured between the second base plate and the first electrochromic liquid crystal mixture layer; the first electrochromic liquid crystal mixture layer reflects first reflecting light, and the wavelength of the first reflecting light is changed along with a first electric field between the first electrode layer and the second electrode layer.

Description

technical field [0001] The present invention relates to a liquid crystal display, and in particular to a reflective electrochromic liquid crystal display. Background technique [0002] Most cholesteric liquid crystal displays are reflective liquid crystal displays, which mainly use cholesteric liquid crystal materials as their reflective layers. In addition, full-color cholesteric liquid crystal display technology has been revealed. At present, the common full-color cholesteric liquid crystal display uses layers of liquid crystal material in three primary colors of red, green and blue to achieve the purpose of full color. Alternatively, the liquid crystal material layers of red, green and blue primary colors are respectively arranged in different pixel packaging structures to achieve a full-color display effect. [0003] If a full-color display effect is achieved by laminating layers of liquid crystal material in three primary colors of red, green, and blue, the thickness ...

AI Technical Summary

Problems solved by technology

[0003] If the full-color display effect is achieved by stacking liquid crystal material layers of the three primary colors of red, green and blue, the thickness of the cholesteric liquid crystal display cannot be reduced.

On the other hand, if the red, green, and blue primary color liquid crystal material layers are separately packaged in different pixels, the reflection efficiency and display contrast of the cholesteric liquid crystal display will be significantly reduced.

Therefore, there are still many unsolved problems in the full-color display technology of this type of reflective liquid crystal display.
