Abstract
A method and system for calibrating brightness variation in a display involve measuring brightness levels of light emitters in the display. The light emitters are divided into different groups based on the measured brightness levels. Each group is assigned a sub-frame duration. Groups with higher brightness are assigned shorter sub-frame durations than groups with lower brightness. Calibration information is stored for driving the light emitters such that during a frame period of the display, the light emitters are activated for durations corresponding to the sub-frame duration of their corresponding group.
