1. An electronic device comprising:
a display that includes an array of pixels and a lenticular lens film formed over the array of pixels, wherein the lenticular lens film spreads light from the display in a horizontal direction and wherein the display has a plurality of independently controllable viewing zones in the horizontal direction;
display driver circuitry configured to control the array of pixels to display images; and
display pipeline circuitry configured to provide brightness values for the images to the display driver circuitry, wherein the display pipeline circuitry includes compensation circuitry that is configured to compensate the brightness values for disparity-caused shift in the horizontal direction, the compensation circuitry stores disparity-caused shift calibration information, and the disparity-caused shift calibration information for a first half of the display is duplicated based on the disparity-caused shift calibration information for a second half of the display.
