Which is the future of television: crt, plasma, lcd, rear projection, front projection?
I know that the new plasma and LCD screen's aren't exactly built to last like the old CRT tubes, yet they are way more costly. What do you think is going to be the TV of the future?
I think one of this: Plasma, LCD or OLED.

The newer Plasma sets are far improved. They have a typical MTBF of about
30,000 hours, just like a CRT set. This type of set can easily have screen burn. For standard TV watching, this will not be a problem. They are coming down in price. The Plasma is about 3 times the price of the equivalent CRT set at this time. Not all of them are HDTV, therefore when shopping around, make sure the one you want is HDTV ready.As for the LCD sets, they are in about the same price range, and maybe more expensive now. The LCD set draws much less power, and is also not able to have screen burn. Most of the LCD models are HDTV ready. The MTBF of the LCD set is typically about 30,000 to 40,000 hours. One of the main problems with LCD displays is that they are mechanically fragile, and are also prone to have pixel failure. The back plane lamp is what will most likely burn out before anything else fails.
A CRT set is about 30,000 hours for the tube. The CRT set can have an image burn, but it is more difficult to burn the CRT than the Plasma display. But, I have seen many CRT sets with image burn.
The hour rating of the display device is the rating that indicates when the display will reach 50% of its rated lumination output.
There are some new technologies coming out. There are supposed to be the new organic LED type displays. These will most likely replace the Plasma displays once perfected. There will be no burnin problems with these.
As for the rear screen sets, I personally find them to not be as sharp as a direct view type set. They are also angle critical for the best quality of view. All of these systems have their drawbacks, and are subject to their problems.
The classic CRT is still the best for cost verses performance. But, the CRT type set has the most errors, and problems for precision or accuracy. They are subject to purity, convergence, and pin distortions. CRT sets are high in radiation emissions compared to the other types of displays.
In a few years from now, I doubt you will be able to see a CRT consumer TV set. They are all going to go with the new technologies as the main stream. There may be some low cost CRT sets being made in the Orient for the low end consumer market, but this market is a shrinking market.
Some of the computer monitor manufactures, and TV monitor broadcast manufactures may be producing CRT monitors for a few more years to be used for specialized applications. These types will be very expensive, and not for home use.
