Abstract: An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a plurality of transparent windows that overlap the optical sensor. The resolution of the display panel may be reduced in some areas due to the presence of the transparent windows. To prevent a visible border between the reduced resolution areas of the display and full resolution areas of the display, uniformity compensation circuitry may be used to compensate pixel data. The uniformity compensation circuitry may output compensated pixel data for the display using one or more compensation maps that include compensation factors associated with pixel locations. The uniformity compensation circuitry may also use region-specific gamma look-up tables to apply different gamma curves to pixels in different regions of the display. The uniformity compensation circuitry may also be used to form a transition region between different regions of the display.

Abstract: An electronic device that includes a display and an eye tracker configured to collect eye tracking data regarding a gaze of one or more of a user's eyes across the display. The electronic device also includes processing circuitry that is operatively coupled to the display and configured to generate pixel data for frames of content based at least in part on the eye tracking data such that the content is configured to be shown on the display in a dynamically foveated manner. The processing circuitry is also configured to apply a dither pattern to the frames of content independent of the gaze of one or more of the user's eyes.

Abstract: Systems and methods may reduce or eliminate image artifacts due to a defective pixel of an electronic display. An electronic display may include pixels that respectively include a self-emissive element, pixel drive circuitry that supplies a pixel drive current to drive the self-emissive element, and signal routing circuitry that reduces or eliminates a visual artifact due to a defective pixel among the pixels. The signal routing circuitry may do this by turning off the self-emissive element, supplying image data from the pixel drive circuitry to a first adjacent pixel, or receiving image data from other pixel drive circuitry from the first adjacent pixel or a second adjacent pixel.

Abstract: 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.
