Compare best prices for rear projection TVs Below are explanation of what each of these terms mean and the benefits of each against the other: Rear Projection Television These are television sets in which the image is projected onto the screen from the back by a lamp. Sometimes this kind of projection is called micro display. They are different from sets that use CRT or cathode ray tube. There are three types of micro displays LCD (liquid-crystal display), DLP (digital light processing), and LCoS (liquid crystal on silicon). Micro display sets are thinner and lighter than sets that use CRT. The lamp that is used has to be replaced every couple of years. Plasma Television Plasma television is almost always a flat panel; this is because it uses technology that allows it to be housed in a smaller panel. Similar to the technology of the fluorescent lamp, the display of a plasma unit contains xenon gas between two glass panels. The gas is injected in the form of plasma; when the gas is charged electrically it lights up red, blue and green phosphors and so an image is created. Red, blue and green phosphors make up a pixel. Meanwhile traditional CRT models use a large vacuum tube, where and electric beam scans the surface of the tube to light up the phosphors and is the reason they have to be housed in larger units. LCD Television LCD rear projection television should not be confused with LCD flat panel televisions. Rear projection LCD uses a powerful light source through a transparent LCD chip made up of individual pixels (which displays the moving video image) and projecting that image through a magnifying lens, to a mirror, which then reflects that image, onto a screen. Because the chip is so small the panel of a rear projection television can be made very thin and light unlike in televisions that use the CRT (cathode ray tube) technology. Although they are still far from being hanged up on the well like plasma or LDC flat panel televisions they can save quite a lot of floor space. They are also cheaper than plasma and LCD flat panel and come with wider screens. LCD rear projection technology is also brighter and offer more contrast.
