Abstract

The invention relates to a total-reflection liquid crystal display, comprising a first substrate and a second substrate of which cassettes are mutually opposite to each other, wherein liquid crystal molecules are clamped between the first substrate and the second substrate; the first substrate comprises a light adsorbing layer for adsorbing ray; the second substrate comprises a transparent electrode and a reflecting layer, wherein the transparent electrode is formed on the second substrate for forming voltage difference between the transparent electrode and the pixel electrode to control liquid crystal inversion, the reflecting layer is arranged between the transparent electrode and the liquid crystal, and the refractive index of the reflecting layer is between the ordinary light refractive index and the abnormal light refractive index of the liquid crystal. The total-reflection liquid crystal display of the invention has high illumination and contrast ratio. Compared with the liquid crystal display adopting the electronic ink technology in the prior art, the invention improves incidental images caused by electrostatic adhesion.

Description

Technical field [0001] The invention relates to liquid crystal display technology, in particular to a total reflection type liquid crystal display. Background technique [0002] In the semi-reflective and semi-transmissive type in the prior art, a reflective layer is added to the lower substrate of the liquid crystal display, so that the light in the environment is incident on the reflective layer and then reflected, and then transmitted from the pixel area, thereby achieving the purpose of display. The problem with this liquid crystal display technology is that due to the principle of polarized light, the luminous efficiency is low, and the brightness and contrast are low. The prior art also provides liquid crystal displays, using electronic ink technology represented by E-ink. The main principle is to use the principle of electrostatic adsorption to control the upper and lower positions of black and white particles with opposite electrical properties in the pixel area to achiev...
