LCD main components
1. Glass substrate: a layer of In2O3 conductive metal, commonly known as ITO, is evaporated on an extremely flat glass surface;
2. Liquid crystal: In 1888, an Australian scientist named F. Reinitzer synthesized a strange organic compound with two melting points. When its solid crystal is heated to 145 ℃, it melts into a liquid, which is only turbid, while all pure substances are transparent when melted. If it is heated to 175 ℃, it seems to melt again, becoming a clear and transparent liquid; The following year, Lenitzer sent the above samples to O Lehmann, please check it. Lehmann confirmed that this material presents optical anisotropy, and according to the characteristics of this "liquid with both liquid fluidity and crystal optical anisotropy", it is called "liquid crystal";
3. Polarizer: also called polarizer, made of plastic film material.
