Liquid-crystal display (LCD) is a flat-panel display or electronically modulated optical device with the light-modulating properties of liquid crystals. The working principle of LCD goes as follows: liquid crystal is a special substance between solid and liquid. It is an organic compound, liquid under normal conditions, but its molecular arrangement appears as regular as solid crystal. That’s why it was named the liquid crystal. Another special property of the liquid crystal is that its molecular arrangement changes when an electric field is applied to it; with a polarizer, it would prevent the light from passing; and by use of a color filter and by altering the voltage working on the liquid crystal, one may discover the transmittance rates of a certain color in it start to change. LCDs are used in a wide range of fields, including LCD televisions, computer monitors, instrument panels, and aircraft cockpit displays. In addition, small LCD screens are common in portable consumer devices such as digital cameras, watches, calculators, and mobile telephones, etc.
