Rear projection television or RPTV is certainly the technology behind the modern day big display television and projector DLP and until recently catered to buyers as the only choice for an affordable screen TV experience.

As the name indicates, RPTV works by using a projector in order to magnify a dimension image out of the video signal onto a screen.

The original RPTV technology, CRT supported RPTVs were the first in order to exceed 40 inch screens. They were bulky and the picture was unclear at close range.

Projector DLP

The best projector DLP creates a graphic utilizing any DMD chip, which on its surface contains any large matrix associated with microscopic mirrors, each corresponding to one pixel in an graphic.

LCD Projectors

In these types of RPTVs, a lamp transmits light through a tiny LCD chip made up of individual pixels to be able to create an image.

RPTV Faces Stiff Competition with LCD plus Plasma

The weight of earlier RPTVs was much heavier than current ones, and weren't able to be wall mounted easily or at all plus even though the majority of buyers don't wall mount their own sets, the ability to do so is definitely considered a vital selling point.
