DLP Front or Rear Projection TV ...continued from page 1
Another strong point is the lack of pixelation. LCD panels have a matrix dividing each pixel, and this shows up, to some extent, on the screen. With DLP, there is no matrix and thus it has a more even texture. However, because of the mirrors, images tend to have a sharper edge appearance. Some people find this appealing while others find it to have more of a "video" than "film" look.
Another issue with one-chip DLP
is that the color wheel can lead to the "rainbow" effect.
Most people do not notice it, but some find the shifting rainbow
of color to be distracting. Some people even find it very objectionable
because it gives them headaches. Newer
models utilize 3 colored LEDS instead of a color wheel which
reduces the chance of a rainbow effect. 3 chip models eliminate
the problem altogether.
Finally, the mirrors are mechanical in nature and thus are prone to mechanical malfunction. A mirror can become stuck, either on or off, resulting in a single pixel remaining fixed on the screen. In many cases, a single pixel will not be noticeable. However, in certain circumstances it can stand out glaringly and even more so if a cluster of mirrors are affected.
DLP overall, delivers excellent
images, its drawbacks should not be enough to dissuade most
viewers, unless of course you find the rainbow effect personally
distracting. Because of its price and wide availability, many
choices abound for DLP TVs. Currently, most DLP TVs have a
resolution of 1280 x 720 (720p) or
1920 x 1080 (1080p).
