The way I understood it...
DLP = Just like the older projection big screens, but much MUCH better. Uses light, has the best picture quality out of anything
LCD = Well, duh. CCFL Backlit LCD panels
LED = LED backlit LCD Panels....same as standard LCD's, but slightly better colors (not a huge deal to me honestly)
Plasma = ???? Fires at Wal Mart????
This is they way I get it, and it's not far off from what you believe.
DLP(Digital Light Processing)
: Uses a silicon chip to precisely diffuse and combine colors. Rear-projection set. Does use a user-replaceable lamp. Actually rather light and thin for a rear-projection set, and can give some amazing picture quality and size for the money.
LCD(Liquid Crystal Display)
: Uses grids of Liquid Crystals switched on/off via electrical signals. Backlit by a non-user replaceable CCFL. Resoloution, contrast, color reproduction and size vary greatly.
LED(Light Emitting Diode)
: Actually a marketing misnomer, LED TVs are merely LED backlit LCD TVs. There are actual LED and OLED TVs in development and technically available for a high price. LED backlit LCDs usually have better color reproduction, better contrast, sometimes better response times and refresh rates eat up a LOT less power, and give off a LOT less heat. They theoretically should have a longer lifespan as well.
: Operates just as it says, with plasma. Think of it as a 21st Century CRT. Essentially there are many cells making up the picture. each one of those cells is excited by a high voltage current to ignite them into a plasma, and emit light. It's a lil more complex than that, but you get the picture(pun intended). They use almost as much power, sometimes more than a CRT, they put off a lot of heat, they used to burn out after a few years if not regualrly filled with an inert gas(dunno if that still holds true), and vary in picture quality and resolution greatly. AFAIK, this technology is on it's way out the door as it's not very efficient, and LED backlit TVs and DLP sets are starting to compete with it's contrast ratios and response times.

If I'm too far off on any of these, feel free to correct me fellow OCNers.Edited by DesertRat - 6/19/11 at 10:49pm
