Abstract: Methods and systems for improved optical efficiency and brightness of display systems are provided herein. Embodiments use laser light sources in substantially continuous mode, thereby increasing the maximum overall output of an optical system. Embodiments exploit the small étendue of laser sources to lower the loss of throughput of an optical system. Embodiments enable a scrolling color scheme that allows a display system to be illuminated with two or more colors at any given time, thereby increasing the brightness of the display system. Embodiments can be used with liquid crystal displays and/or digital mirror displays. Embodiments can be used in single-panel and/or two-panel display systems.

Abstract: Methods and systems for multiple primary color display are provided. Methods and systems of the present invention improve the spectrum efficiency of a color display system, and provide enhanced brightness and color gamut. In an embodiment, methods and systems of the present invention improve the brightness of a color display system employing a high pressure lamp by efficiently incorporating lights components of the lamp output that are outside the red, green, and blue spectrum in creating the color image.

Abstract: A peripheral projection, display screen system including (a) a display screen having a rear side and a diagonal dimension, (b) an image-projection source coupled to a peripheral of the system and disposed at a defined, image-projection system depth rearwardly of the screen's rear side, (c) an optical path structure operatively interposed and optically coupling the source and the rear side of the screen, coupling the image from the source to the screen's rear side, and within the mentioned, defined image-projection system depth, a displayable image projected by the source, and (d) system geometry structure organizing the screen, the source, and the optical path structure, whereby the depth ratio of the diagonal dimension of the screen to the image-projection depth is equal to or more than 10:1.
