1 lasers + lcd = true, Epson

3 lasers + sxrd = true but when?
I don't get the "math" above. The Epson system is a 3 LCD system, so they will be using 3 LASERs. Instead of color filtering on any of the LCDs it will just use the color of each of the 3 LASERs.
The same for DLP. But with DLP, they will all point at the same chip, just fire in rapid sequence, much like a colorwheel, but significantly faster, enough so to eliminate rainbows. Probably limited only in how fast the micro-mirrors are.
LCOS (or SXRD) is like a combination of the above 2, in that it uses LCDs, but they are reflective. Here it will be 3 lasers again, one for each chip.
With this, the iris (maybe), special lensing and filters should all go away. The thing I would need to know, is if the laser hits the whole chip at once, or is it indexed to every pixel. If it is indexed, then you could control the brightness with the laser and wouldn't need help from an iris control.
Although, thinking about it, even if it hits the whole chip at once, you could modulate the laser in much the same way as an iris would, so the iris still wouldn't be needed. In this way, more complex iris type clamping could occur, say a scene with very little blue in it, the blue laser could be nearly shut down.
