what is the difference between Widescreen HD LCOS/HD-ILA Rear Projection TV and A rear projection DLP or LCD?

Answer 1

LCOS is an LCD in the surface of a slicon semiconductor. It is only used for projection TV and is employed in SONY SXRD and JVC D-ILA displays. Light is reflected through the liquid crystal layers, passing through the LC twice. In standard LCD, light is passed through the LC from behind, and goes through once. Because of the double pass, LCOS LC layers are thinner, and the pixels can be placed closer together. LCOS also provides higher contrast ratios than standard LC.

DLP works on an entirely different manner; a chip consising of an array of microscopic mirrors is used to form the image. This method also works by reflecting light and provides high contrast ratios and very high brightness levels.

Answer 2

PLASMA makes use of gas in plasma form for show, lcd makes use of lcd and a mild source for show DLP digital mild Processing makes use of a colour wheel and shifting mirrors Plasma television remains the most important, yet lcd television is now also accessible in a length similiar to a medium Plasma television and a tremendous one also furnish extra proper evaluation. a tremendous lcd television tend to be better in cost than a Plasma television interior a similar length. DLP rather below plasma and has a smaller marketplace percentage. A DLP has a bulb that has to get replaced on an time-honored foundation. it must be rather severe priced yet may be done by using the buyer. both lcd and Plasma are skinny sufficient to mount on the wall even as a DLP is a lot lighter yet feels like a customary television As for different varieties TVs. you could also opt to seem at getting a projector and mount it to the ceiling.
