High Resolution Scalable Displays: Manufacturing and Use

Tiling projectors provides an effective and easy option to increase screen space. Differences in projectors' components however contribute to non-uniformities in illumination and colour and detract from image quality and useability. In collaboration with JVC we developed a compact, high-resolution, uniform, tiled projection computer display based on a single common light source. A single set of red, green and blue dichroic filters provides the red, green and blue illuminations which are then guided by optical fibres to the projectors D-ILA (Direct Drive Image Light Amplifier) chips, JVC's projector technology. This results in a uniform illumination across the tiled projectors, a single colour temperature and a single colour balanced spectrum, with improved image uniformity. The display is driven by a graphics computer cluster running Linux and fitted with Nvidia graphics cards. We illustrate applications of this new display system with scientific applications in medical imaging and in radar imaging for archaeology. .
