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 liquid crystal display. Background technique [0002] In the semi-reflective and transflective type in the prior art, a reflective layer is added on 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, so as to achieve the purpose of display. The problem with this liquid crystal display technology is that due to the use of the principle of polarized light, the luminous efficiency is low, and the brightness and contrast are low. In the prior art, there is also a liquid crystal display, which adopts the electronic ink technology represented by E-ink. Reflection or absorption of light. This kind of liquid crystal display has high contrast, and the display effect is similar to that of paper display, that is, it can display black ...
