READ THE FOLLOWING TO HELP YOU DECIDE:

 

LCD

Advantages

  • Slim profile
  • Lighter and less bulky than projection televisions
  • Generally have higher resolutions than plasma displays: plasma displays were able to achieve the 1080-progressive, high-definition resolution but it required a 50-inch screen size. LCD's were able to achieve this with a 32-inch screen.
  • Is not susceptible to burn-in: Burn-in refers to the television displaying a permanent ghost-like image due to constant, prolonged display of the image. Light-emitting phosphors lose their luminosity over time and when frequently used, the low-luminosity areas become permanently visible.
  • Does not suffer from glare in bright rooms
  • Can be mounted on walls

Disadvantages

  • Poor black level: Some light passes through even when liquid crystals completely untwist, so the best black color that can be achieved is a very dark gray, resulting in worse contrast ratios and detail in the image.
  • Generally have smaller viewing angles but this is improving due to advanced technologies like MVA and PVA
  • More difficult, and therefore more expensive, to make LCD's with large screen sizes: LCD's rely heavily on thin-film transistors, which are often defective, resulting in a defective pixel. The number of defective pixels at which the LCD is determined to be unusable varies. LCD's currently have a rejection rate of about 50% but this is improving. A larger screen size requires more transistors, which increases the chances of yielding a defective LCD. This contributes heavily to a large LCD costing significantly more than its plasma counterpart of equivalent size. Technology advancements are slowly easing this problem.
  • Typically have slower response times, which can cause ghosting and blurring during the display of fast-moving images.

 

Plasma Display

Advantages

  • Slim profile
  • Lighter and less bulky than projection televisions
  • Easier to manufacture and cheaper at large screen sizes than LCD's
  • Can achieve a true black because pixel can be completely turned off, resulting in better contrast, detail, and naturalness
  • Better viewing angles than those of LCD's but this is quickly becoming a non-issue

Disadvantages

  • Significantly more expensive than projection televisions
  • Susceptible to burn-in: Burn-in refers to the television displaying a permanent ghost-like image due to constant, prolonged display of the image. Light-emitting phosphors lose their luminosity over time and when frequently used, the low-luminosity areas become permanently visible.
  • Phosphors lose luminosity over time, resulting in gradual decline of image quality
  • Generally have lower resolutions than LCD's: plasma displays were able to achieve the 1080-progressive, high-definition resolution but it required a 50-inch screen size. LCD's were able to achieve this with a 37-inch screen.
  • Susceptible to reflection glare in bright rooms.
  • Plasma screens run a lot hotter than LCD or projection, because of the need to heat the gas into a plasma. For this reason, plasmas cannot generally be mounted over fireplaces or similar hot areas.

Projection Television

Advantages

  • Significantly cheaper than flat-panel counterparts
  • Front-projection picture quality resembles that of movie theater
  • Front-projection takes up very little space because a projector screen is extremely slim, or alternatively the wall could be used as the display medium
  • Display size can be extremely large, up to hundreds of inches
  • Projectors that are not phosphor-based (LCD/DLP) are not susceptible to burn-in: Burn-in refers to the television displaying a permanent ghost-like image due to constant, prolonged display of the image. Light-emitting phosphors lose their luminosity over time and when frequently used, the low-luminosity areas become permanently visible.

Disadvantages

  • Front-projection more difficult to set up because projector is separate and must be placed in front of the screen, typically on the ceiling
  • Rear-projection televisions are much bulkier than flat-panel televisions
  • Lamp may need to be replaced after heavy usage
  • Rear-projection has smaller viewing angles than those of flat-panel displays
  • Rear-projection is susceptible to glare

IF It's Rear-projection, I DEFINITELY. wouldn't go there. If you get too far on the ground, or too high up, it looks like crap, gets dark, and you can't see crap. My friend has one. It's not good, especially for multiple people. I Reccomend. LCD. I have a 45" (or something close to it) and I love it.
