Projectors Offer Cheaper HDTV

Projectors Offer Cheaper HDTV In the pricey world of high-definition TVs, digital projectors -- once reserved for business presentations and high-end home theaters -- now offer an unlikely combination of virtues: enormous, flat screens at relatively cheap prices of around $1,000 each. ¶ These tabletop digital light processing (DLP) projectors work like film projectors, throwing a moving image onto a wall or screen at sizes from 20 to 200 inches, as measured from corner to corner. (DLP technology is also used in pricier rear-projection HDTVs; in those sets, the image is projected toward the viewer and onto a regular glass screen.) [Washington Post's TechNews.com]
