Eastman Kodak announced Thursday it has built a prototype d-cinema projector using laser projection technology, a “tech holy grail” that promises to solve several problems for digital cinema and digital 3D.Kodak, which is showing the system to industry leaders at its Rochester, N.Y. theater, said the projector produces deep blacks, wide dynamic range and a bright 3D image. Lasers are smaller than existing projector lamps, and run cooler, so they reduce air conditioning requirements. They also draw less power, reducing ongoing costs for digital projection. Wednesday at the 3D Entertainment Summit, Jeffrey Katzenberg predicted such laser projectors would soon solve many of the brightness issues with 3D. (Daily Variety, Sept. 16, 2010).
