What is Liquid Crystal Display(LCD)

LCD stands for Liquid Crystal Display a type of display technology which composed of several layers. That include two polarized panels, with a liquid crystal solution between them. Light is projected through the layer of liquid crystals and is colorized, which produces the visible image.

LCD are used to create digital displays in devices such as television screens, monitors, and mobile phones.

Unlike OLED Liquid crystals do not emit light directly, instead using a backlight to produce images which means that an LCD consume more power. But are lighter, thinner and consume less power than CRT.

There are two primary types of LCDs: TN (Twisted nematic) and IPS (in-plane-switching).

TN (Twisted Nematic) is the most common technology and also the oldest. The main advantage is that it provides the shortest response times, making them good for gaming. In combination with LED back-lighting, TN monitors also offer high brightness and draw less power than competing technologies. Another important factor is that they are cheap to manufacture, resulting in low prices for end users.


IPS (In-plane switching) is a screen technology for liquid crystal displays (LCDs). It was designed to solve the main limitations of the twisted nematic field effect (TN) matrix LCDs. It has better viewing angle and good-quality color reproduction than TN panels.
