Abstract
Brightness between the individual tiles of a tiled display system is matched for improved uniformity and overall brightness of images produced by the display system. Regions of the display system adjacent to a tile with low brightness performance are incremented in brightness from the brightness level of the low brightness tile to the brightness level of higher brightness tiles. By incrementing the brightness of such regions according to embodiments of the invention, perceived brightness uniformity of images produced by the tiled display system is maintained while maximizing the overall brightness of the display device. The regions used to increment brightness may be as large as an entire tile or as small as a single pixel element.
