Abstract
An aspect of the present invention proposes a solution to allow low-cost flat panel displays without light guides to maintain a high quality image display via enhancement of pixel data to account for non uniform brightness. According to one embodiment, each pixel of a display is mapped to the brightness (intensity) of illumination that reaches the pixel. Regional pixel gains are calculated and applied on a per pixel basis to compensate for the non-uniform brightness across the screen. According to such an embodiment, even low cost flat panel displays experiencing non-uniform brightness can be used to render high quality images.
