LCD rear projection.
WHAT IT IS. These systems shine a high-intensity light through a single LCD
panel or three individual LCD panels for Red, Green and Blue. The resulting light is
projected through a series of lenses and reflected off a mirror behind the screen.
BENEFITS. Systems that use three LCD panels—one each for red, green and
blue—can achieve superlative picture quality. LCD rear projection can deliver
slightly better color than typical DLP™ models because the three LCD panels can be
individually adjusted. LCD rear projection features compact size and light weight.
Easy bulb replacement by the user brings the television back to like-new brightness
levels. The LCD panels are fixed in place and therefore need no convergence
adjustment. LCDs are immune from "burn-in," so there's never any harm from
videogames left on too long, DVDs in pause or station logos on the corner of the
screen. LCDs also need no magnetic shielding from your loudspeakers. And there
are no altitude limits.
LIMITATIONS. Black levels and contrast still cannot match today's best CRTs.
Can't quite match the viewing angle of direct-view CRT.
