Saw the Vivid Red at the Professional Products technology fair this week in Greenbelt, Md. The projector is not yet ready to roll out, so it still had tweaks to be worked out (some are amusing: a remote control button was labeled "manu" instead of "menu").
Given it is a "work-in-progress", I was impressed with the quality of the picture, especially coming from such a small-sized projector. And as always with LCOS (D-ILA) systems: "pixels, what pixels?"
It was a pleasure to meet Frank Weathers of Christie Digital. The man knows his stuff!
I went to the show to get some more ideas on upgrading my Vidikron Crystal One-based home theatre, since the Sharp 9000 didn't work for me.
Speaking of the show, I also finally got to meet Tom Stites of JVC in person -- another class act, who was very helpful as usual.
The colours don't have to be bad, but you will lose more lumens to obtain accurate colour because the bulb will put out less red light. With proper calibration the advantages of DVI make the unit really appealing, in theory. I hope the contrast ratio is up with current units.
Ah ah ah, not so fast. Being a physicist won't save you from being mistaken this time.
What you say is very true for incandescent bulbs, including Xenon bulbs. Obviously, there are some efficiency issues with these bulbs and new technology has moved in a different direction.
The spectrum of an incandescent bulb is very even without many high peaks or valleys, UHP bulbs and the like behave more like flourescent bulbs and have very peaky spectrums.
I believe as efficiency increases, the colour temperature rises and, as you say, you get a larger proportion of blue light or a paucity of red light.
Xenon bulbs have, I believe, a colour temperature of around 5500K, close to the 6500K standard. The CCT of more exotic bulbs like UHP are much higher and to get them back to 6500K you need to sacrifice a lot of blue and some green light.
Hopefully someone more familiar with bulb technology will comment on the technical details.
