MURA CORRECTION FOR AN LED DISPLAY

An example processing system for driving a display having light-emitting diode (LED) sub-pixels is described. The processing system comprises a memory that stores a first plurality of values for a first LED sub-pixel of the LED sub-pixels and a processing circuit. The processing circuit is configured to: receive image data for the display, the image data comprising a first input digital code for the first LED sub-pixel; and generate a first output digital code using a non-linear function having an argument and a plurality of constant parameters, where the processing circuit is configured to set the argument to the first input digital code and the plurality of constant parameters to the first plurality of values. The processing system further comprises a display driver, coupled to the display and the processing circuit, comprising a first digital-to-analog converter (DAC) configured to control intensity of emitted light from the first LED sub-pixel in response to the first output digital code.
