Find Out About How The Projector DLP Set Works

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

Magnifying Details - How Does any Rear Projection TV Work?

As the name implies, RPTV works by using a projector to magnify a size image out of the video signal onto a big screen. The projector uses a brilliant beam of light and a lens system to project the picture to a much bigger size. The traditional TV setups usually are in some ways similar to the RPTVs. The television box contains the projector inside then the projector projects the image form at the rear of the screen.

CRT Projectors

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

Projector DLP

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

LCD Projectors

In these RPTVs, a lamp transmits light through a little LCD chip made up of individual pixels in order 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 and even though most consumers don't wall mount their sets, the ability to do so will be considered a vital selling point. The modern-day rear projection TVs have a smaller footprint compared to their predecessors and the recent models usually are lighter. But RPTVs still fall short compared to the latest LCD and plasma flat panels which are lighter using superior picture resolutions.

While well-liked in the early 2000s as an alternative to much more pricey LCD and plasma flat panels, the falling price and improvements to LCDs have led to Sony, Philips, Toshiba, and Hitachi planning to drop rear projection TVs out of their lineup. Currently, Samsung, Mitsubishi, ProScan, RCA, Panasonic, plus JVC RPTVs remain in the market.
