I was going to submit that but HN dupe check prevents it (it was originally submitted 1,001 days ago). Unfortunately it also appears that you can not discuss HN submissions that old, so there is no appropriate place to then discuss the other chips in that article.
Of particular interest to me is the DMD (Digital Micromirror Device). I had not really thought about how a digital projector might work, but if I had I would've said that it would be screen based. I wouldn't have guessed that the light would be projected at a microchip which would then reflect back only the pixels to be lit using incredibly small mirrors. And that this would happen so quick that the light would be sent through a gel of colour and would cycle through red, green, blue, and that the mirrors would reflect only a given colour at that moment for the pixel concerned.
To be fair the DMDs in projectors are a fairly recent innovation. I was interested in projectors in HS, and at that time all projectors were either CRT or LCD based. However, DMDs were an "exciting new technology" that had promises for cinema projection since they could be significantly brighter than the CRT and LCD projectors of the time. I certainly didn't think they would be available in home projectors in under a decade like they were (though the color wheel certainly helped with that)
