ABSTRACT:
The present invention features a tiled, flat-panel display (FPD) that has color-matching between the tiles, which is accomplished by a direct transformation of video data through values stored in tables, and addressed by the spatial position in both the display and the input data value. One or more transformation tables are disposed proximate a graphics controller, which synchronizes, routes and controls the timing of data to data (column) drivers of the FPD. The transformation tables may be read-only or read-write memory devices. They are used to provide data representative of corrections or adjustments of color luminance on a pixel-by-pixel, or sub-pixel-by-sub-pixel basis, thus matching color of all portions of a display tile and all tiles in the FPD. This invention also describes a method of determining the values for the tables by measuring the common luminance response of the regions of the display.
