Rear projection television or RPTV is actually the technology guiding the modern day large screen television and projector DLP plus until recently catered to buyers as the only option for an affordable big screen TV experience.

Magnifying Details - How Does a Rear Projection TV Function?

As the name implies, RPTV uses a projector in order to magnify a size picture out of the video signal onto a large display. The projector uses a vivid beam associated with light and a lens system in order to project the picture to a much larger dimension. The traditional TV setups are usually in a number of ways similar to the RPTVs. The television box carries the projector inside then the projector projects the image form behind the display.

CRT Projectors

The earliest RPTV technology, CRT backed 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 image making use of any DMD chip, which on its surface contains a huge matrix of microscopic mirrors, each corresponding to one pixel in an image.

LCD Projectors

In these types of RPTVs, a lamp transmits light through a small LCD chip made up of individual pixels in order to create an image.

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 and though many buyers don't wall mount their sets, the ability in order to do so is definitely considered a vital selling point. The modern-day rear projection TVs have a smaller footprint than their own predecessors and the recent models are usually lighter. But RPTVs still fall short in comparison to the latest LCD and plasma flat panels which are usually lighter using superior picture resolutions.

While popular from the early 2000s as an alternative to more expensive LCD plus 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, and JVC RPTVs remain inside market.
