Classification: CPC G | IPC G

Claim 14:
15. A compensation system of a display device, the compensation system comprising:
a processor configured to provide compensated data to display driving circuitry configured to program image data onto a pixel of a group of pixels of the display device by:
receiving image data configured to be displayed on the pixel, wherein the image data comprises gray level data for the pixel;
converting the gray level data to first voltage data;
fetching, from a memory of the display device, compressed 1×1 pixel uniformity compensation data for the pixel, wherein the compressed 1×1 pixel uniformity compensation data comprises compensation data to mitigate non-uniformity between the pixel and one or more other pixels when supplied with a same electrical input signal;
decompressing the compressed 1×1 pixel uniformity compensation data via a decompressor, wherein the decompressed data comprises the 1×1 pixel uniformity compensation data for the pixel;
determining a voltage compensation offset value associated with the pixel based on the 1×1 pixel uniformity compensation data for the pixel;
generating compensated voltage data based in part on the voltage compensation offset value and the first voltage data;
converting the compensated voltage data to compensated gray level data; and
transmitting the compensated gray level data to the display driving circuitry to program the pixel based upon the compensated data.
