TILED, FLAT-PANEL DISPLAYS WITH COLOR-CORRECTION CAPABILITY

摘要

The present invention features a tiled, flat-panel, color display (20) that has a color-correction capability (24). The display is a tiled mosaic of individual display tiles (22), such as AMLCDs. Column and row inpu ts that are typically provided for a single display tile system are distributed over a plurality of display tiles. The color purity is achieved for the display by sorting the tiles into groups, matching their color coordinates, and correcting non-uniformities optically (e.g., by using a graded neutral density filter (28) having a grading function being the inverse of the brightness distribution non-uniformities) and/or electronically. Then, each individual tile in the mosaic is color-corrected via a multiplexed controller/driver circuit (12).
