Abstract
A method for control of a pixel array based on a temperature estimate is provided. A method includes sampling an anode voltage of each LED of a plurality of pixels resulting in sampled voltages, determining an average voltage based on the sample voltages, and determining a total voltage to provide to the pixels based on the average voltage and voltage data from a memory coupled to the controller, the voltage data including one or more of a 3-sigma value, a driver headroom value, a resistance value, or a k-factor value.
