How Rear Projection TVs Work
Rear
projection TVs are often an economical way to get a big screen and a great picture. They can be thinner than traditional CRT sets, but aren't thin enough to mount on a wall, as you might with a plasma or LCD flat screen.
As the name indicates, a rear
projection television contains a projector, which transmits images from behind the screen through a lens that magnifies them to fill the available viewing space.
There are several different projector technologies in use. The most popular are CRT, LCD, DLP and LCoS.
