Compare Plasma LCD and Rear Projection HDTVs – A Guide
The following article contains a guide on how to compare plasma and LCD rear projection HDTVs are used, including the differences between the technologies in each.
Many people are confused by words in the electronics industry today, such as "Rear Projection TV", "plasma" and "LCD flat panel. To understand exactly what you are buying, if you need to buy one of these products, you first understand the underlying technology that behind each.
You need to know whether the generalScreen TVs are better than normal flat-screen TVs, and that plasma screens are better LCD screens. The difference between LCD rear projection and flat-panel sets is also important.

Rear Projection TVs include: This TV a lamp behind a screen, an image on the monitor projects. This technology is also known as a micro-display and is from the more traditional CRT, or cathode ray tube, various technologies used in older TV sets.
There are three different types of micro-display – namely Liquid Crystal Display (LCD), Digital Light Processing (DLP), andLiquid Crystal on Silicon (LCoS). While television, with micro-display technology, flatter and lighter than television, which need to CRT technology, the lamps in micro-displays will be changed once every two or three years.
Plasma TVs are: This TV is almost always in the form of a flat panel display, as technology that manufacturers the necessary electronics in a shallow House panel allows you to use.

Through the gas was injected in the form of plasma, and then an electric charge, making it to glow in red, blue and green, making a picture. Each pixel consists of red, blue and green phosphors.
Traditional CRT televisions contain, however, a vacuum tube, which sends an electric beam across the surface of the tube, the phosphors glow. Thus, the displays are larger than theModern.
Liquid Crystal Display Televisions

This brief introduction to the HDTV technology should be of some use if you want to compare plasma and LCD rear projection HDTVs. You should aspect ratio, screen size, resolution, compare, HDMI interface and price, if you have a TV.
