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 inputs 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).

Quadrillage d'écrans couleur plats (20) possédant une fonction de correction des couleurs (24). L'ensemble forme une mosaïque d'écrans individuels (22), par exemple à affichage à cristaux liquides à matrice active (AMLCD). Les entrées par colonne et par ligne qui caractérisent généralement un système unique de quadrillage d'écrans sont réparties sur plusieurs écrans de la mosaïque. On obtient la pureté des couleurs du quadrillage en triant les écrans par groupes, en assortissant leur coordonnées de couleurs et en corrigeant les défauts d'uniformité de façon optique (par exemple en employant un filtre neutre de densité progressive (28) ayant une fonction de gradation inverse des défauts d'uniformité de distribution de la luminosité) et/ou de façon électronique. Les couleurs de chaque écran composant la mosaïque sont ensuite corrigées par l'intermédiaire d'un circuit multiplex de contrôle et de commande (12).
