I'm in love with the Sammy 5063. The technology is pretty neat...
They took their DLP board and turned in 1/8, making each pixel a diamond. They then swivel each mirror on two axes, and project the image in two passes (interlaced). The image has a 1/2 pixel overlap on each pixel, meaning pixel structure is almost completely lost. (This is harder to explain, by, the way, than I thought...). The process is called "wobulation" (no joke)
Essentially it's like sideways interlacing. Imagine the screen width as having 1020 lines of resolution. This chip takes its mirrors and projects an image onto pixels in each odd line, starting with 1, and going through 1019. Since the vertical line information is square, but the pixels are diamonds, each pixel bleeds slightly into the next line. Next, the even lines 2-1020 are rendered, and again, there is some pixel bleeding. Do this fast enough, and the pixel structure dissappears entirely.
There are some drawbacks - softness is one of them. But on an HD source, its nearly impossible to notice any of the softness because the 1020 lines of resolution are so close together. With standard broadcast (where several lines of resolution share the same information - resulting in blockiness, jaggies, etc.), the image is much improved.
Beware that this techonology is not favored by some who prefer a more geometrical clarity/"hardness" to their image, and reject softness out of hand (even though I believe it makes video look more "film like"). Also, Sammy is coming out with new TVs with new chips that are supposed to far surpass the 5063 technology.
As always, your mileage may vary. Go to the store and see for yourself. For one, I really hate the screen door effect on the Sony GW. I find that the macro-blocking that occurs with regular TV is amplified to a point where the image doesn't look good.
