Types Of Liquid Crystal Display. This is so because the molecules of this nematic crystal are somewhat naturally twisted at an angle of about 90°. Lcd (liquid crystal display) is a type of flat panel display which uses liquid crystals in its primary form of operation.
It is also the least expensive. Lcd’s technologies allow displays to be much thinner when compared to a cathode ray tube (crt) technology. The two alignments layer for the liquid crystal material are orthogonal.
