This is a confusing time now. SED sounds very interesting but when? And HOW MUCH? If SED is all that why would Toshiba put out a 55" 1080P SED TV that exceeds all other technologies significantly and then drop a $4k price tag on it when a 58" 720P Panny Plasma goes for $5300? Regardless, it sounds like it's at least 1-2 years away.
The demo of the Mits Laser DLP as stated from hdtvexpert said:
"Not surprisingly, the demo RPTV had plenty of speckle, not to mention over-saturated greens and reds. The speckle from the lasers was aggravated by the natural grain of the micro lenses in the rear-projection screen. The images were about as bright as those on conventional RPTVs, but the combination of speckle and the interference patterns with the RP screen's lenses resulted in some pretty soft-looking HD clips."
So I'd have to guess that laser dlps are going to their own set of issues from the start.
As far as LED DLPs go, LED sounds nice as far as fixing issues with the bulb. However, I've not heard anything to lead me to believe the picture quality will be any better. I thought I heard the contrast ratio of the LED DLPs will only be 2500:1 which is four times lower than the current bulbs. Meaning that black levels and brightness probably won't be as good. And if that's the case, why would I want to pay more for an LED DLP when the standard bulbs outperform them?
