Liquid crystal display (UK: Liquid Crystal Display) LCD is also known as a media type that uses liquid crystal display as the primary viewer. LCD’s are used in various fields such as in electronic appliances such as televisions, calculators, computer screen or even electronic device like Garmin Etex handheld GPS. 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.


You like watching TV? What kind TV you have? LCD TV or plasma TV? Now many people change their plasma TV with LCD TV, although they do not know why they change their TV. And now let us compare LCD plasma TV, we see the superabundance and the lack of this two electronic devices. The first, plasma TV given different contras of colour black and white prefer than LCD TV. This lack of LCD TV will see exactly if we see from corner out LCD TV which matches. The second, plasma TV bring out the first light colour; the colour is matching with room situation. And LCD TV is bringing out good colour at the room light. Plasma TV have corner of see 160 degrees. It means, we can watch on the TV.

LCD TV is better than plasma TV, LCD TV has complete details. Like computer. Although plasma TV also completed, but LCD still better than plasma for their looks. Plasma TV has good image, and have high contras. LCD TV has shadow follow the image. But plasma TV and LCD TV have the same time in their life. Depend on the model. Plasma TV uses two times power than LCD TV. And LCD TV has high resolution.
