LCD Projection TV

LCD projection TVs use an LCD (liquid crystal display) to produce the picture and then project them on a screen. This is true of both rear projection and front projection TVs.

At their core, LCD projection TVs contain a small LCD, and therefore derrive much of their properties from the qualities of LCDs. LCD panels can be manufactured to have high resolution and small size, therefore, LCD projection TVs can have high resolution screens. The small size of LCDs is perfect for portable front projection TV units, and contributes to lighter rear projection televisions. On the other hand, the distance between the pixels of an LCD tends to be large. Even good LCDs have no more that 50% of their display area covered by pixels and the rest by gaps, and in LCDs of lesser quality this can be down to 12%. The intra-pixel gaps reduce picture shapness and contribute to a visible "screen door" grid on LCD projection TV's screen. Low contrast, the difference between maximum and minimum brightness, is another problems LCDs tend to have, as compared with other display technologies.

Overall, the pluses and minuses of LCD technology make it a very popular projection TV technology. The problems associated with LCD projection are minimized in high end LCD projection TV units. If you are concerned about picture quality and are willing to spend more, you might want to look into a DLP projection TV.
