DLP television

LCD (Liquid Crystal Display) TV

Advantages

LCDs are good for still images and make good computer monitors. So, if you're looking for a screen for TV and computer use, LCDs are a good bet
Quality LCDs have excellent brightness level pictures.

Disadvantages

LCDs are not good for fast-moving pictures. When an object moves quickly across the screen, the image "delays" (there are trails of pixilation or blockingess), because the screen can't keep up. For this reason, LCDs that are 37" or smaller generally have better image quality because the delay is less notice able than on larger LCDs.
LCD TVs have difficulty with black levels
LCDs are very expensive over 35"
LCD image looks great when you'restaring directly at it, but if you are watching from a slanted view the quality of the image can diminish greatly.

DLP (Digital Light Processing) TV

Advantages

DLP screens are larger and are cheaper in the short-term than LCD or Plasma.
Good brightness and color. DLP can illuminate a larger screen for more people at a cheaper initial cost than Plasma.

Disadvantages

There's a high maintanence cost. The DLP TV is basically a video projector in a box. You have to replace the lightbulb, which has limited durability.
DLPs take up a lot more space than Plasma and LCD and are not wall mountable.
DLPs don't have as good field vision as Plasmas, meaning you can't get as good picture quality when viewing the screen at an angle.
DLPs are not known for having that great of picture quality.

Plasma TV

Advantages

Top name brand plasmas have a fairly long life, lasting about 20 years at a six hours per day pace.
A plasma screen has a field vision of about 180 degrees without loss of picture quality. That means you can watch the screen from any angle.
Plasmas are very bright (about 4-5 times brighter than the average TV)
They have great contrast ratios (enables them to show better shadow detail)

Disadvantages

Plasmas can have burn in problems. Plasmas do not make as good computer monitors as LCDs. If you were to leave the Plasma TV on for 24 hours a day and there was an image that remained con stant on the screen (like a logo), you would run the risk of that image perma nently burning into the screen.
