Basic structure of LCD liquid crystal display screen
three basic components and features of LCD liquid crystal:
glass substrate: a kind of thin glass sheet produced by float method with extremely flat surface, there is a layer of Zn203 or Sn02 transparent conductive layer, that is, the ITO film layer, which is processed into a transparent conductive pattern. If it is scratched, cut or corroded, the vacuum device will be scrapped.
liquid crystal material: Liquid crystal material is the main body of liquid crystal display screen. Different devices use different liquid crystal materials, most liquid crystal materials are mixed with several or even a dozen of single liquid crystal materials.
polarizer: the polarizer is also called polarized light, which is made of plastic film material and is coated with a layer of optical sensitive adhesive, which can be attached to the surface of the liquid crystal box. There is also a protective film on the surface of the front polarizer, should be removed when using, polarizer afraid of high temperature, high humidity, in high temperature or high humidity conditions will make its depolarization or foaming.
