Rear Projection TV Review ... 3 Great Options In Big Screen Television
How Rear Projection TV Works – Technology Revealed. Rear projection TV includes the latest generation of HD-ready televisions that actually contain their own projection system. A high fangled home-ready knock off of the cinema theater technology, rear projection TV manipulates incoming signal (think light beams) ... then re-directs white light against a matrix of mirrors to split the light beam into colors.

LCD Rear Projection TV. One half of the rear projection TV segment is dominated by LCD TV models ... utilizing at their core "liquid crystal display" or LCD technology such as you might find on high-quality computer monitors, watches, digital instruments.
* LCD Rear Projection Technology Explained. In LCD rear projection TV, the incoming light source (signal) created by the projection unit itself is channeled into a dense photon light beam. Next, the LCD projects an image onto the white light beam. Projected light carries the image to the front of your LCD rear projection TV, where literally millions of pixels are processed each second, in timing increments measured in parts of billionths of a second. What you get is a stunning image, with images and brightness amplified, and reflections and room light dampened electronically.
DLP Rear Projection TV. Analogous to its LCD rear projection TV competitor, DLP rear projection TV or "digital light processor" manipulates incoming broadcast signals ... processing them digitally into binary "bits" or images. Next, the DLP rear projection TV channels images onto a separate dense light beam which is projected onto the front of your TV screen. Like its LCD rival, popular DLP rear projection TV models operate virtually at the speed of light ... millions of pixels processed seamlessly each second, and where timing and the internal folded optical system measures performance in billionths of a second. Cool, fast stuff ... and you get the viewing results!
Rear Projection TV LCOS . Another technology migrating into the home theater market is rear projection TV LCOS. Like LCD TV, rear projection TV LCOS, or "liquid crystal on silicon", utilizes much of the processing strategies of signal processing, image transfer common to LCD rear projection TV as well as DLP rear projection TV. Bottom line? You're getting greater viewing image and sound quality. Differences boil down to manufacturers' production and pricing capability.
CRT Projection TV – CRT HDTV Option. Another option to look at is the CRT HDTV option. Seemingly antiquated cathode ray tube or CRT TV technology battles to stay top of mind for consumers. Primary weapon for CRT projection TV makers? Pricing.
CRT projection TV utilizes three core cathode ray tubes ... one each for green, red, or blue light frequencies. The next step, transferring images onto the unit's condensed light beam "feels" analogous to DLP rear projection TV or LCD technology. The "rub" with CRT projection TV is that it requires exhaustingly detailed set-up ... plus relentless re-tuning of the image ... balancing the color values and brightness in order to achieve the image quality that's "automatic pilot" with DLP or LCD unitsCopyright 2004-2010 S&T US LLC
