Abstract: A display control system includes: a display including a plurality of pixels; a lookup table including grayscale values and magnitudes of power corresponding to the grayscale values, respectively, where first ones of the grayscale values that are less than a predetermined grayscale value are calibrated based on the display achieving a gamma of greater than 2.2 and second ones of the grayscale values that are greater than the predetermined grayscale value are calibrated based on the display achieving a gamma of 2.2; a driver module configured to: based on a grayscale pixel map including a grayscale value for each pixel of the display, determine magnitudes of power to apply to pixels, respectively, using the lookup table; and apply power to the pixels of the display according to the determined magnitudes of power, respectively.
