Going back to the Dolby Cinema for a minute, I became fascinated with the projectors there and did lots of digging around.
The technology is very clever indeed.
The colour gamut is as a result of their being six different laser sources. Two different frequencies each of red, green and blue. In the Dolby London installation, all the lasers are in a separate room next door to the projection room, and linked to the projectors with fibre-optic cables. There is a whole rack full of lasers, and they are turned on and off in various combinations depending on the light levels needed at that instantaneous moment in time.
The black levels are due to there being six DMD assemblies in the projector. Three 4K ones and three 2K ones. Each combined laser light source then passes across the two DMDs in series.
So this is, effectively, a freakish kind of full array dimming with 2 million dimming zones per colour. Basically every four pixels has a dimming zone.
And, possibly, the most amazing thing is that Christie are willing to sell a version of this solution for home cinema use. Millionaires only need apply though as it's going to be mid six-figures!
This would make for a great AVForums article. Wonder if someone can get Christie on side?
