A. OVERVIEW
A liquid crystal display (LCD) is an increasingly popular type of display used in a variety of
digital display applications. LCD’s utilize two sheets of polarizing material with a liquid crystal
solution between them. An electric current passed through the liquid causes the crystals to align
so that light cannot pass through them. Each crystal, therefore, is like a shutter, either allowing
light to pass through or blocking the light.
LCD’s have the advantage of low power consumption, sharpness and brightness of images,
perfectly flat screens and zero geometric distortion.
