The projector uses a vibrant beam associated with light plus a lens method to project the image to a a lot bigger dimension. The traditional TV setups are usually in several ways similar to the RPTVs. The television box contains the projector inside then the projector projects the graphic form behind the screen.
CRT Projectors

Projector DLP

LCD Projectors
In these kinds of RPTVs, a lamp transmits light via a little LCD chip made up of individual pixels in order to create an picture.
RPTV Faces Stiff Competition with LCD and Plasma
The weight associated with earlier RPTVs was much heavier than current ones, and weren't able to be wall mounted easily or at all plus although most people don't wall mount their own sets, the ability to be able to do so is actually considered a vital selling point. The modern-day rear projection TVs have a smaller footprint compared to their own predecessors and the recent models are lighter. But RPTVs still fall short compared to the latest LCD plus plasma flat panels which usually are lighter using superior picture resolutions.
While well-liked in the early 2000s as an alternative to more costly LCD plus plasma flat panels, the falling price plus improvements to LCDs have led to Sony, Philips, Toshiba, and Hitachi planning to be able to drop rear projection TVs from their own lineup.
