Abstract
A novel rear projection screen that displays images with substantially uniform brightness over a wider field-of-view than prior rear projection screens, comprising a first diffusing assembly for diffusing the image and a second diffusing assembly for further diffusing the image from the first diffuser. In the preferred embodiment, the first and second diffusing assemblies comprise an input diffusing screen and a fiber optic array, respectively, with an output diffusing screen used at the output end of the fiber optic array. A preferred flat panel tiled display system that incorporates the present invention includes a plurality of collimated light sources, with respective liquid crystal display assemblies that impart images onto the collimated light beams. An imager images the image-bearing light beams onto the rear projection screen described above so that they are displayed in a tiled arrangement.
