LCD (Liquid Crystal Display) is a type of screen used in many computers, mobile phones, laptops, and TV. It is a very thin display panel but is actually composed of several layers. These layers include two polarized panels with a liquid crystal solution between them. It works on the principle of blocking light so it consumes less power than LED and gas display displays. In this display, light is projected through the layer of liquid crystals and is colorized so that it produces a visible image.
