1. A display comprising:

  • an array of pixels having individually adjustable brightness levels;

    an array of light sensors fixed relative to the pixel array, wherein the array of light sensors extends around the display; and

    a brightness controller configured to estimate a glare footprint on the pixel array from light level data provided by the sensor array by connecting a light-to-dark change point for one of the array of light sensors located at one side of the display with a complementary dark-to-light change point for another of the array of light sensors located at another side of the display and to adjust the relative brightness levels of pixels that fall in the estimated glare footprint, wherein the array of light sensors in its entirety extends around the display in its entirety.
