So I was thinking about how some of these systems use color wheels, and trying to understand why they aren't using a pure white light... Now, I don't know if this is what they are doing, but something we might consider...
Instead of using white LEDs, what if we use RGB LEDs (like NT-53F0-0428) with a B&W LCD... The LCD would be cheaper, faster transitions, better contrast... Basically, alternate between R/G/B (all LEDs at once) and flood the LCD... which either allows it to pass through or not... In theory, we might be able to get better contrast and faster response times, while still making it cheaper (though a little more complex).

Of course, another option would be 3 Polysilicon LCDs - one for each color... they could be all on at once. Then alignment is more of the issue.
or 3 Polysilicon LCDs with white light and each can have a filter
