Liquid crystal display

Abstract

The invention discloses a liquid crystal display. The liquid crystal display is characterized in that quantum dot materials are doped in a color resisting layer so that quantum dots are motivated by back lights to form lights with definite spectrum, and lights with different polarization states selectively penetrate through an anisotropic polarization layer prepared by organic dye molecules to obtain linear polarization lights. According to the liquid crystal display, the light-leaking problem caused by changing the light polarization states under the quantum dot materials can be effectively solved, the contrast ratio is increased, and the upper or lower polarizer can be replaced by the polarization layer; thus one polarization pasting process is omitted, the manufacturing process is simplified, the cost is saved, and the polarization effect can be better realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or laptop screen, etc. Generally, a liquid crystal display device includes a housing, a liquid crystal display panel disposed in the housing, and a backlight module disposed in the housing. Among them, the structure of the liquid crystal display panel is mainly composed of a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), a color filter substrate (Color Filter, CF), and a liquid crystal layer ( Liquid Crystal Layer), its working principle is to control the rotation of liquid crystal molecules in the liquid crystal layer by app...

Apparently, this optical switch doesn't fully respond to the light emitted by the quantum dots.

[0008] In addition, iodine is often used as a dichroic substance in polarizers in traditional liquid crystal displays, but iodine has a large sublimation property, so it is not good in heat resistance and light resistance, and the extinction color of iodine is dark blue, so It is not an ideal colorless polarizer for the entire visible light range, which is detrimental to the display effect of liquid crystal displays
