Magnifying Details - How Does a Rear Projection TV Perform?

As the name suggests, RPTV works by using a projector in order to magnify a size picture from the video signal onto a large display. The projector uses any vibrant beam of light and a lens system in order to project the image to a much larger dimension. The conventional TV setups are generally in several ways similar to the RPTVs. The television box carries the projector inside and the projector projects the image form behind the display.

CRT Projectors

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 image making use of a DMD chip, which on its surface contains a huge 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 little LCD chip made up of individual pixels 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 plus even though the majority of consumers don't wall mount their sets, the ability in order to do so is actually considered a vital selling point. The modern-day rear projection TVs have a smaller footprint than their own predecessors plus the recent models are generally lighter. But RPTVs still fall short compared to the latest LCD and plasma flat panels which are usually lighter with superior picture resolutions.

While popular from the early 2000s as an alternative to far 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 from their lineup. Currently, Samsung, Mitsubishi, ProScan, RCA, Panasonic, and JVC RPTVs remain inside market.
