Sony @ CEDIA - Take a close look at the SXRD

Sony is confident about their SXRD technology. So confident that they want CEDIA attendants to take close look at it - very close via the provided magnifying glass. SXRD is an LCoS variant and therefore is a very good picture even at that close of a range. Sure, there was some lines and grains when scrutinized but there wasn't another manufacturer at the show with enough, er, backbone to provide a similar demo.

I just got the 55A2000, and it's amazing. I would have gone with the Samsung DLP, but I not only see rainbows, but my friend's DLP projector gives me a pounding headache if I watch a whole movie on it. The LED DLP, the Pearl, and the SXRD XBR2s coming later this year are too expensive, but the 55" after both the Sony price drop and the discount from Tweeter was very affordable.
If price wasn't as much as a factor, I'd definitely have gone with the Pearl, since it's one of the very few displays that can really do 1080p24.

The reason why LCoS is a good display technology is one of its technological traits known as fill-factor. For a given amount of space to create a 'pixel' there is waste. This wasted space is the result of providing a gap between this pixel and the pixels adjacent to it. The less wasted space the higher the fill-factor.
LCD has the worse fill-factor of any fixed-pixel display technology. In fact, many relate to looking at an LCD image like looking at a photograph through a screen door on your house. Hence, the 'screen door effect' (aka SDE). Typical fill-factor for LCD is around 50-60% (used for image, rest is wasted space).
DLP has a fill-factor of around 89-90% (unless it has changed recently) and LCoS more along the lines of 93-94%. One of the things about the fill-factor between DLP and LCoS is their leading edges. DLP has a sharp (some say crisp) leading edge, but this could be taken to making the image pixelilated. LCoS has a more softer leading edge and often is said to produce a more film-like image.
But, with all competing technologies they have the strengths and drawbacks. For instance, LCoS (like LCD) has a rather low native contrast ratio while DLP is much better. On the other hand, you are not going to see DLP rainbows with LCoS (or LCD).

I have a new Samsung DLP, and I can't see rainbows on it unless I take some ecstasy first. Of course, then I pretty much see them everywhere.
