摘要: An image display device includes an image processing unit, a light source assembly, an optical modulator assembly, and a projection lens assembly. The image processing unit is configured to receive a video signal and generate image data and control signals. The light source assembly and optical modulator assembly are each controlled by the control signals such that the light source assembly generates illumination in a spatial distribution pattern that is coupled to optical modular assembly via a homogenizing device. The projection lens assembly is configured to project an image from the optical modulator assembly onto a viewing surface. The optical modular assembly is configured to maximize the amount of illumination coupled from the light source assembly, and includes at least one optical modulator surface configured to have a substantially 1:1 aspect ratio.

摘要: A method of reducing stray light contribution of a display system is described. Light rays are directed to at least one pixel of the display system and the light rays are modulated to form modulated light. In addition, the modulated light is directed to display optics, and the reflected light is directed away from the display optics.

摘要: A light coupling system includes a waveguide, configured to receive light from at least two light sources and to internally reflect light therein; a diffraction grating, disposed upon the waveguide; and a switchable Bragg grating, disposed upon the waveguide. The diffraction grating is configured to couple light from at least one of the light sources into the waveguide, and the switchable Bragg grating is configured to selectively couple light out of the waveguide, such that the light from the at least two light sources is selectively directed along a common projection axis.
