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 knowif widescreen is 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.

Before you buy one of these electronic items, you should know exactly what they mean their first names, so you're not from the seller at your local electronics store confused. You will then be in a position to decide what is worth the money, andwhat is not.

The following are brief introductions to be used in each of these technologies in modern televisions.

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) and Liquid 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.

A plasmaTelevision show works the same way as a fluorescent lamp, consisting of two panes of glass with xenon gas between them. 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 lightsthe phosphors. Thus, the displays are larger than those of today.

Liquid Crystal Display Televisions

LCD rear projection is not the same as LCD flat screen TV, a rear projection LCD TV is moving production of an image by projecting light through a transparent LCD chip, which shows the individual pixels, the video images and to project the image after front through a lens is made that the image is enlarged to a mirror that reflects the endImage on the monitor.

The chip is inserted into a rear projection, very small, and thus is extremely easy, taking less space than the traditional cathode-ray tubes in television sets.

While LCD rear-projection televisions are not as compact as plasma or LCD flat-screen TVs, they are still much smaller than in conventional television sets. These TVs are cheaper than plasma and LCD flat screen TV in comparisonand they also have larger screens. LCD rear-projection systems also offer brighter images and greater contrast.

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. They should also enable comparisons between similar models of different brands of TV, as they may bedifferent.
