Abstract
A technique for masking a non-functioning pixel in a display screen includes receiving pixel values for driving pixels on the display screen with an image, identifying a sub-set of the pixel values associated with surrounding pixels that are adjacent to the non-functioning pixel in the display screen, and adjusting the pixel values of the sub-set to increase brightness of the surrounding pixels to compensate for lost brightness due to the non-functioning pixel to thereby mask visual perception of the non-functioning pixel.
