Plasmas are still nowhere as good as a CRT for contrast as they don't have near as dark blacks. The dark areas still contain a high amount of high frequency noise. They also are a linear device using PWM, so they require electronic gamma correction which can compromise dark area detail. Even with later generation technology, they are prone to burning. Their green phosphors tend to be bluish which lowers color accuracy, but this can be corrected with color management.
LCDs have come a long way to catch up with plasma and exceeds it in some respects. Burning is not a problem, but retention can be. This seems to vary between displays from non-existent to almost as bad as plasmas. However they will tend to fade out after a while though I have seen some that never quite do. Colorimetry of LCDs have reached to extended gamuts. Ghosting has nearly been eliminated though it's still a limitation for alternating image display of 3D. Viewing angle has vastly improved but blacks still become raised when viewing off angle. For casual viewing it's not that big of a problem.
DLP and LCOS are limited to projection. While the quality is very good, the projection requirement limits how thin the display can be made for rear projection. Consumer rear projection screens tend to be plastic which creates color sparkling on bright scenes. LED illumination improves DLP as a mechanical wheel is not required, and improves both technologies with expanded color gamut. DLPs use PWM, so using a single device in sequential color mode can compromise the amount of gray scale levels. Like plasma it depends on the shortest duration possible in the PWM.
OLEDs have great contrast comparable to CRTs, have great colorimetry, no burn or retention issues, no viewing angle issues, no dark area noise. The main issue has been the deterioration of the individual colors. On cell phones this isn't as much of an issue as they tend to have a limited lifetime. But on a computer or video display, especially at the high price premium, this could reduce their appeal. However this has improved tremendously. They are still a linear display so PWM is required, but these devices can have a very short duration. OLEDs look to possibly be the winner of the direct view display race, especially with their thin displays.
If color e-paper can match the speed and quality of other display technologies, it may become the ultimate winner.

[citation][nom]Travis Beane[/nom]Now that's just full of awesome sauce.Though, I must ask, what's its static contrast, colour gamut, response time, light output, power use, life expectancy etc. You know, all those standard goodies.[/citation]
You can speculate a bit just by knowing a bit of OLED.
Response time will be lightning fast (600hz refresh)
Light output will be quite bright.
Contrast will absolutely melt your face. A "classic" contrast ratio doesn't apply here as it results in a divide by zero.
Color gamut..not sure
Life expectancy will be lower than other traditional monitors.
Power use will vary drastically. It will be near zero for an all black display, but slightly higher than LCD if displaying all white.
Really though the spec that matters unfortunately is the price. It's still out of my range so those other goodies are irrelevant.

[citation][nom]rpmrush[/nom]Every plasma I've seen boasts 600hz. OLED is simply the lighting. Is this an lcd or plasma?[/citation]
It's neither. It's OLED.
Not to be confused with LED (the higher end background lighting on LCDs)
OLED means there is NO backlight. The pixels themselves glow, not just filter a glow from a backlight.
My lil Zune HD has an OLED display and it's the most beautiful one I've ever seen. I'll take OLED over IPS LCD any day.

They've been going crazy over here (I happen to live in South Korea) over OLED displays lately. They've been trying to cram them into every device imaginable, from portable media players to cell phones. Their not cheap though but neither was Plasma / LCD when they were first developed.
This is more a sneak preview / look ahead of what could be coming down the pipe in the next 3 ~ 5 years. The first LCD's had all sorts of issues but years later their the standard.
