Abstract

Users needs for more pixels in displays are starting to be met as manufacturers increase the native resolution of projector chips. Tiling several projectors still offers a solution to augment the pixel capacity of a display. However problems of color and illumination uniformity across projectors need to be addressed as well as the computer software required to drive such devices. We present a novel, compact, high-resolution, uniform, tiled projection computer display. All projectors are illuminated by a common light source, utilizing a fiber optic beam splitting system and a single set of red, green and blue dichroic filters. This ensures uniform illumination across the tiled projected images, a single color temperature, color balance and stability, with improved image uniformity. The display performance is characterized by photometric measurements. We investigate also spectral losses in the screen material. The utility of the new display system is illustrated by a scientific application in air-borne radar imaging for archaeology.
