The following article contains a guide on how to compare plasma and LCD rear projection HDTV uses, including the differences between the technologies in each of them.
Many people are confused by what the electronics industry today, such as "Rear Projection TV", "plasma" and "flat-screen LCD. To understand exactly what you are buying, if you need to buy one of these products, you must first understand the basic technology that behind everyone.
You need to know if widescreen is better than normal flat-screen TVs, plasma displays and LCD screens are better. The difference between LCD rear projection and flat-panel set is also important.
Before buying one of these electronic items, you should know exactly what they want to say their names, so you're not from the seller at your local electronics store confused. There will then be able to decideWhat is your value of money and what is not.
The following are brief introductions to be used in each of these technologies in modern televisions.
Rear projection TV include: This TV lamp behind a screen, the image on a monitor projects. This technology is known as a micro-display and comes from the more traditional CRT, or cathode ray tube, the various technologies used in television sets larger.
There are three different types of micro-display – that is,Liquid Crystal Display (LCD), Digital Light Processing (DLP) and Liquid Crystal on Silicon (LCoS). While the television, with the 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 monitor, as the technology that manufacturers the necessary electronics in a house allows you to use a flatPanel.
Displaying a Plasma TV 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 shine in red, blue and green, making a picture. Each pixel is composed of red, blue and green phosphors.
Traditional CRT TVs, however, contain sounds a vacuum tube through which an electric beamthe surface of the pipe and lit up the phosphors. Thus, the screens are larger than those of today.
Liquid Crystal Display Televisions
LCD rear projection is not the same as LCD flat screen, a rear projection LCD TV is moving production of an image by projecting light through a transparent LCD chip, which shows the individual pixels, video images and for projecting the 'image after the face through a lens made up of increases thatthe image on a mirror, reflecting, finally, the screen image.
The chip is inserted into a rear projection, very small, and therefore it is extremely easy, taking less space than traditional cathode-ray tubes for televisions.
While LCD rear-projection TV are not as compact as plasma or LCD flat-screen TVs are still much lower than those of conventional TVs. These TVs are also less expensive thanplasma and LCD flat screen TV in comparison, and also have larger screens. LCD rear-projection systems also offer brighter images and greater contrast.
This brief introduction to HDTV technology would be useful if you want to compare plasma and LCD rear projection HDTV. You should aspect ratio, screen size, resolution, compare, HDMI, and price, if you have a TV. You should also allow comparisonTV similar models of different brands, how they can be different.
