CONFIGURABLE PIXEL UNIFORMITY COMPENSATION FOR OLED DISPLAY NON-UNIFORMITY COMPENSATION BASED ON SCALING FACTORS

Abstract:

A system may include an electronic display panel having pixels, where each pixel may emit light based on a respective programming signal. The system may include a memory storing a map. The processing circuitry may determine a function for each pixel from the map. The processing circuitry may determine a respective control signal based on the function and a target brightness level for each pixel to generate multiple control signals, where the respective control signal is used to generate the respective programing signal for each pixel. The processing circuitry may determine a scaling factor based at least in part on the first map and may scale at least a subset of the multiple control signals based at least in part on the scaling factor.
