Patent number: 11908376Abstract: A compensation system includes a processor configured to determine compensated data for display on a sub-pixel of the display device. The processor may receive image data configured to be displayed on the sub-pixel, convert the gray level data to first voltage data; fetch, from a memory, compressed 1×1 sub-pixel uniformity compensation data for the sub-pixel, and decompress the compressed 1×1 sub-pixel uniformity compensation data via a decompressor. The decompressed data comprises the 1×1 sub-pixel uniformity compensation data for the sub-pixel. The processor may also determine a voltage compensation offset value associated with the sub-pixel based on the second voltage data, generate compensated voltage data based in part on the voltage compensation offset value and the first voltage data, convert the compensated voltage data to compensated gray level data; and transmit the compensated gray level data to pixel driving circuitry associated with the sub-pixel.Type: GrantFiled: March 31, 2022Date of Patent: February 20, 2024Assignee: Apple Inc.Inventors: Lingtao Wang, Giovanni Carbone, Chaohao Wang, Enkhamgalan Dorjgotov, Sheng Zhang, Jim C Chou, Shereef Shehata, Yung-Chin Chen
