Claim 18:
19. A non-transitory machine-readable medium including instructions that, when executed by a controller of a light emitting diode (LED) array, cause the controller to perform operations comprising:
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 that is three times a standard deviation of forward voltages of the pixels, a driver headroom value that indicates how much higher than a forward voltage a driver voltage needs to be for the driver to operate the LED, a resistance value that is an estimate of an equivalent resistance used to determine I*R losses from a control system, or a k-factor value that indicates how much to increase VLED if there is a change in content to be provided by the LED.
