  • Correction of visible mura distortions in displays using filtered mura reduction and backlight control
    Publication number: 20100013751
    Abstract: A display that includes at least one gray level being provided to a plurality of pixels that illuminates each of the pixels with the gray level. The display applies interpolated corrective data for the pixels so as to reduce the mura effects of said display and modifies the backlight of the display.
