Everything About LCD Monitor

By: Govy

Liquid Crystal Display(LCD) is technology that uses rod-shaped molecules (liquid crystals) that flow like liquid and bend light. Unenergized, the crystals direct light through two polarizing filters, allowing a natural background color to show but when it is energized, filters redirect the light to be absorbed in one of the polarizers, causing the dark appearance of crossed polarizers to show. The more the molecules are twisted, it produces a better contrast and viewing angle.

Since less power is needed to move molecules than to energize a light-emitting device, LCDs replaced the light-emitting diodes (LEDs) in digital watches in the 1970s. Eventually, LCDs were used for monochrome displays and still are and in the 1990s, color LCD screens caused sales of laptop computers to explode. In 2003 to date, more LCD monitors were being sold for desktop computers than the bulky and space consuming CRTs.
