LCD’s now dominate the type of display for desktop and notebook computers because they require low power, thin shape, spend a little heat, and with high resolution.

In such a colour LCD monitor there are many points of light (pixels) which consists of a single liquid crystal as a point of light. Though referred to as points of light, but this liquid crystal does not emit light itself. The source of light in an LCD device is a white fluorescent lights at the rear of this liquid crystal composition. Point of light whose numbers tens of thousands or even millions that has shaped the image display. Polar liquid crystals through which electrical current will change because of the influence of magnetic fields arising from the polarization and thus will only be continued while letting some other colours of the colour filter. LCD technology was discovered since the year 1888, is the processing of liquid crystal is a liquid chemical, where the molecules can be arranged in such a way if given the electric field such as metal molecules when given a magnetic field. When set correctly, the rays can pass through the liquid crystal.
