Abstract
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.
