Austria botanists discovered a whitish viscous liquid, after the German physicist who discovered this kind of opaque material has a variety of bending properties, that this substance is a liquid crystal, which is named LiquidCrystal liquid crystal. The world's first liquid crystal display device appeared in the early 1970s, known as the TN-LCD (twisted nematic) lcd. Although it is monochrome display, it is still being extended to the field of electronic watches,
calculators, etc.. Liquid crystal is a between solid and liquid substances, is an organic compound with regular molecular arrangement, if the liquid state heat it will appear transparent, cooling it appears turbid crystalline particles in solid state. The liquid crystal molecular structure of a liquid crystal display device is arranged in a similar fine match stick, which is called a Nematic liquid crystal, and the liquid crystal display device which is manufactured by the liquid crystal is also called LCD (LiquidCrystalDisplay). The LCD TV is adding voltage in liquid crystal between two sheets of glass,
nd by the molecular arrangement and tortuous changes through the electronic reproduction screen screen group collision, make the picture and form images by reflecting light external perspective. It is better than LCD TV in the treatment of burn plasma TV, but when the still image is in the same position of the plasma screen, it may burn.
