I don't know if this link has been posted before, or

if anyone is really interested, but I found this document

that has some pretty neat technical descriptions

(toned down for the "layperson") of the dILA technology:

Good find!


I found the comparisons to DMD (DLP projectors) and CRT particularly interesting, since we often compare the different projector technologies here.

This should really fuel the CRT vs digital argument:


from pages 9/10


"9) QXGA picture sharpness

With the QXGA panel, extremely sharp pictures can be achieved. The spatial

frequency characteristics (MTF) for CRT and QXGA are shown for comparison.

For CRT, the response is attenuated in high frequencies due to the beam spot

shape with Gaussian characteristics. In general, MTF5% is said to be the limit

resolution of the CRT. Therefore, even with a master monitor, MTF is greatly

lowered in resolution of 1000 TV lines. On the other hand, with the QXGA panel,

attenuation of only about 10% occurs due to projection lens. So, 1536 TV lines of

the number of vertical pixels can be obtained. The difference in area for the MTF

characteristics clearly shows the difference in sharpness. Therefore, with QXGA

panel, sharper and higher-resolution pictures than ever can be seen. On the down

side, artifacts in sources will also show up clearly."


end quote.


The chart representing this difference is quite striking.

I was one of the lucky one to have seen a demo of a qxga dila at siggraph this summer. what can I say, this projector is simply amazing!

Rick,


I found that quote interesting as well.


Reading between the lines, it basically says that even the best CRT won't be able to fully resolve a 1080i HDTV feed, but this puppy will be able to do it without breaking a sweat.
