LCD – Liquid Crystal Display


An LCD is a display that consists of 2 layers of glass with a super-thin layer of liquid crystal sandwiched between them.The gap between the 2 layers of glass is as little as 6µm (to put that into contect, a human hair is 50-60µm). Liquid crystals do not emit light directly, instead using their light modulating properties with a backlight or reflector that provides light to individual pixels arranged in a grid. Each pixel has a red, green, and blue RGB sub-pixel that can be turned on or off.

When all of a pixel's sub-pixels are turned off, it appears black. When all the sub-pixels are turned on 100%, it appears white. By adjusting the individual levels of red, green, and blue light, millions of color combinations are possible.

LCD displays come in many variations including TN, STN and TFT
