Cornerstone Technology for Diffusion of Digital Cinema
Sony SXRD 4K Projectors

They are known as the 4K projector because they project at a pixel width and height of more than twice that of HDTV - 4096 wide x 2160 high. This technology quadruples the resolution of modern HDTV projectors and provides a contrast ration of 2000 to 1 with up to 10,000 ANSI lumens.
With such impressive specifications, these projectors are expected to provide the cornerstone enabling digital cinema to replace the presently ubiquitous 35mm theater movie projector. The talk goes beyond describing the enabling technology - Silicon Crystal Reflexive Displays. It also deals with Sony's strategy for digital cinema deployment and reviews infrastructure issues to put these projectors to use. They are shipping this month.
This lecture with technical diagrams explains in depth how this new technology works. These projectors are in the $100k price range. A smaller home theatre Qualia C-340- projector from Sony is available using the same technology for only about $12k.
