What is LCD monitor?

LCD (liquid crystal display) screens use an entirely different technique. The screen is still made of dotes but is quite flat. LCD displays are made of two layers of polarizing materials with a liquid crystal signal makes the crystals line up in a way that keeps light from going through entirely on just partly. A black screen has all the crystals lined up to that so light gets through. A color LCD screen uses groups of 3 phosphor dots. The signal for a picture cleverly let just through sports show their colors. Your eye does the rest. It not ruins our eye. It shows the picture or data clearly. So that it is famous in market.
