Seriously? Wiki/Google much?
Regular tv’s: not the black and white ones, color, crt models. Cathode Ray Tubes, has a gun in the back, shoots junk towards the front. Known for superior black colors and contrast.
Plasma: Panes of glass, tubes of gas. Superior contrast ratio, much much much higher than traditiona lcd’s, talking 2million to one and up. Newer models have the same lifespan of lcd’s 60,000 hrs to 100,000 hours. Much higher refresh rate @ 600hz, faster response time .001ms. Perfect for movie watching and regular tv watching. Not as high of a chance for image retention as they used to be, newer sets you’re looking at about 10-12ish hours before it happens, or so they say. Usually have a glass panel on the front which can give you more reflection in brighter rooms. But much better for fast action stuff.
LCD tv: I call these traditional LCD’s. You have an lcd panel with the lightsource behind it, this case they are basic CCFL Tube Lights. Low contrast, high end sets have a 100,000 to one dynamic contrast ratio. Only go up to 240hz vs plasmas 600hz. You’d be hard pressed to even see the difference from a 120hz vs a 240 hz on regular movies or tv, yet alone 240hz vs 600hz. No chance of burn in, so more recomended for heavy gaming and pc connection, since both tend to have the most static images. They lose a little contrast at the higher viewing angles. The panels without any glass front will simply absorb light.
LED: as far as consumer led tv’s they are actually LED LCD TVs. they have a LCD panel but instead of CCFL lighting they have LED lights. You get high dynamic contrast, comparable to plasmas 2 mil and up, without the draw back of the plasmas burn in. so they are well suited for superior movie watching and hooking up to your pc, or viewing photos on them without any risks. only up to 240hz as far as refresh rate, but, like i said above, you really really have to nitpick the details to see the difference from 120vs240. there are 3 types of led lighting systems. edge lit; lights are around the edge of the tv pointing inwards which makes the set super thin. downfall to that is, to me at least, you get an even washed out look on the black areas. second type is full array backlighting without local dimming (sharps). the lights are on the back of the tv dirrectly which means you get better lighting directly on the panel itself. the third is full array with local dimming, this is going to be the best out there. the lights are in the back behind the lcd panel, but the lights locally dim according to the picture. so, lets say the top right of the picture is darker, the tv will adjust that set of lights lower or turn off while leaving the rest of the lights in the tv alone to give you truer blacks and better contrast of colors. the samsung 8500 seires does this, as do the toshibas and lg’s. even though the sharp doesn’t do this, they have amazing panels that don’t leak as much light and are still sexy tv’s.
DLP: projection tv’s, i stay away from the traditional ones. they implement a light bulb, a color wheel and the mirror chip by texas instruments. the chip has tons of little tiny mirrors that switch on and off, reflecting or not reflecting light onto the screen infront. trick to these is that…well, light bulbs burn out and these arent cheap, 200 bucks and up usually. tons of moving parts. the tv themselves though are crazy cheap for the sizes you can get. newer models like mitsubishi are changing things though. instead of the lamp and a color wheel they are putting a laser array thing to beam lights into the chip. so much more reliable system, nonetheless it is old tech, i’d stay away unless you want a super huge tv for cheap.
plasmas used to have the market on big sets vs the lcds, but lcds you can get in 65 inches, sometimes 70 (i think sharp had one a while ago), and plasmas can get pretty huge too. LED lcd’s are topping at 55 for the time being.
but thats the gist of it.
