Abstract

Devices, storage media, and methods for compensating for aging and temperature variations using dual-loop compensation are provided. The compensating for temperature and aging variations of one or more pixels of the display using a coarse scan loop updated at a faster rate. Compensation also includes compensating for aging variations of the one or more pixels of the display using a fine scan loop updated at a slower rate.
