Hi guys,
Just wondering if any of you have looked into DLP technology, which is essentially very tiny mirrors that can be digitally controlled (either tilted one way or the other). Texas Instruments were pushing this big a couple of years ago, and still seem to be reasonably keen on the technology. It sure does look pretty cool and overcomes many of the problems with the transmissive system that many of you are developing.
I'm not sure of cost however, and imagine that it will be pretty high. The developement kit which consists of a single DMD (Digital MicroMirror Device) and some control logic costs US$5000. I'm not sure how much is actual physical cost, and how much is recoup for the required development time to create the board.
If anyone has some more info on this kind of stuff I would be incredibly happy to receive it.
Thanks for listening,
Bevan Weiss

Where I work we have a dell projetor that uses the DLP technology. It looks great, and has fast action, perfect for movies and such. I took it home an saw a movie on it, and loved it. Cost:2100 dollars(us). ouch, but its better in my opinion than a 4000 dollar rear projection tv I saw the other day at a high end electronics store. It also supports HD resolutions.

Theres the link to it. Its not made by dell, I cant remember who makes it, dell just seels it.

Both ZeroAlias and I saw a a very nice Infocus DLP projector in action at a local college. While the contrast looked VERY nice, the "rainbows" were far less than acceptable. Every time you scan your eyes across the screen you see this terrible RGB stripe in the middle of your eye. After a few minutes, it actually started to give me a headache.
After seeing the projector, I have decided that I will never buy a DLP until they get much fast color wheels that eliminate the "rainbows."

What about if the screen didn't actually use a colour wheel?
After all, only the cheaper units use a colour wheel to prevent requiring three DMD units. The colour wheel only requires one. I've sent a couple of emails to TI concerning availability of the DMD's however it seems they are only released to large manufacturers. Anyone got any ideas bout how to get some (cheaper than buying a projector for them)??
