Design Considerations for Cinema Exhibition Using RGB Laser Illumination

Laser light sources used in digital projectors have the potential to increase quality for several image parameters, including high brightness, dynamic range, and color space. This paper discusses advantages of laser illumination for digital projection, as well as considerations for the design of future cinema parameters such as luminance standards, high dynamic range projection, and a wider color space, including the practicality of the color space of The International Telecommunications Union Radiocommunication Sector Recommendation ITU-R BT.2020 (Rec. 2020)1as a projection gamut. Practical concerns and limits of lasers are examined in the context of near-term implementations, and suggestions for future theater and projector design are discussed.
