OLED VS Lasers

The thing is the OLED is a direct view display technology like LCD flat panels, but far more sophisticated, while Lasers are a front or rear projection technology for technology like DLP or LCoS. Unlike those technologies, Lasers are a scanning technology like a CRT, which is why CRTs have produced those precious blacks you know (and videophiles love).

I perfer Lasers because IMO I am a front projector fanatic that wants a really big screen and the shape I like it, but there is no denying how impressive OLED is as it can become a form of paper for example, and may even replace the thinness and convience of projection screens.

What is your call?

Interesting discussion point, but I disagree with some aspects about how the technologies are framed. Lasers aren't fundamentally a scanning technology like CRTs. Most work done with them to this point use them in more of a flood illumination mode onto a DLP or LCoS. In this respect there isn't much difference from a lamp based projection TV. Also, I personally wouldn't characterize OLED as more sophisticated, but that is probably a question of semantics. They are a far more simple concept, but much more difficult to manufacture, primarily because of the issue with material degradation when exposed to oxygen.

If they can get around the speckle issue in a cost effective way, I think laser projection will dominate the large screen market while OLED comes along in smaller screens and ultimately replaces laser projection. Once it is cheap to produce large flat OLED panels, I can't see a reason for the competing laser technology, unless there is a breakthrough in a holographic display technology. Basically I see these as two different technology generations for large screen TVs. I can't imagine laser surviving at the same price point as OLED. The difference in available color space will be negligible if both use only three or four color projection. I guess it is possible that laser TV manufactures could keep pushing for an advantage by adding color sources faster than OLED can keep up, but I don't see this happening for very long. I can't wait for the day when I'm struggling to choose between the two though.
