TFT LCD (Thin Film Transistor Liquid Crystal Display) has a
sandwich-like structure with liquid crystal filled between two
glass plates.TFT Glass has as many TFTs as the number of pixels
displayed, while a Color Filter Glass has color filter which
generates color. Liquid crystals move according to the difference
in voltage between the Color Filter Glass and the TFT Glass. The
amount of light supplied by Back Light is determined by the amount
of movement of the liquid crystals in such a way as to generate
color.
