• LCD monitor

Liquid crystal display (English: Liquid Crystal Display) LCD is also known as a media type that uses a liquid crystal display as the main viewer. LCDs are used in various fields such as in electrical appliances such as televisions, calculators or computer screen.

In such a color LCD monitor there are many points of light (pixels) that consists of a single liquid crystal as a point of light. Although referred to as points of light, but the liquid crystal does not emit its own light. The light source in an LCD device is a white fluorescent lamps at the rear of the liquid crystal composition earlier.

Points of light whose number tens of thousands even millions of images that has shaped appearance. Polar liquid crystals through which the electrical current will change magnetic field due to polarization effects that arise and therefore will only let a few colors while other colors passed filtered.

• monitor the plasma

Plasma display is a flat screen display emisif in which light is produced by the phosphor is excited by a plasma discharge between two flat-screen glass. Gas released its cargo does not contain mercury (as opposed to AMLCD); a mixture of noble gases (neon and xenon) is used. Gas mixture is difficult to react to and are completely harmless.
