Abstract
An electronic display is driven to compensate for aging of pixels in the electronic display. An aging factor is determined based on initial display data for a display portion of the electronic display during one or more monitored frames. The aging factor is indicative of aging of pixels in the display portion of the electronic display due to use corresponding to the initial display data. An aging counter for the display portion is increased based on the determined aging factor. A compensation value is determined for the display portion based on the aging counter for the display portion. Input display data for the display portion is modified during a subsequent frame according the determined compensation value. The display portion is driven with the modified input display data during the subsequent frame.
