Electronic devices, displays, and methods are provided for operating an electronic display in coexistence with sensors that could be adversely impacted by the operation of the electronic display. An electronic device may include an electronic display and a sensor. The electronic display may display image content by light emission during an emission period and periodically enter a quiet period in which the light emission of the electronic display is turned off. The sensor may perform sensing operations during the quiet period without interference from the operation of the electronic display.

Electronic display timing to mitigate image artifacts or manage sensor coexistence

To reduce image artifacts and non-uniformity associated with a display pixel of an electronic display, processing circuity may adjust a luminance value corresponding to a display pixel according to a per-pixel gain mask, a per-pixel anode mask, or both. To further correct for the non-uniformity, the processing circuitry may convert the luminance value to a digital code based on a curve associated with an anode on which the display pixel is located.

Display pixel non-uniformity compensation

An electronic device may display image content via an electronic display by controlling light emission from display pixels of the electronic display. A processor of the electronic device may receive image data destined for a defective display pixel (e.g., dim pixel, dead pixel). The processor may convert a gray level of the image data into a luminance domain to generate a target luminance that would have been emitted by the defective display pixel had the display pixel not been defective. After selecting a compensation mask, the processor may distribute the target luminance of the defective display pixels to nearby non-defective pixels of the electronic display to conceal the presence of the defective display pixel.

Systems and methods for point defect compensation

An electronic device may display image content via a tile-based display by controlling light emission from display pixels of the tile-based display. Based on image data associated with the image content, a processing circuitry of the tile-based display may receive a potential tile boundary. The processing circuitry may resample the image data based on geometry of the tile boundary and positions of the display pixels on the tile-based panel. After resampling the image data, the processing circuitry may adjust gain of the tile boundary display pixels according to a gain mask to compensate for the tile boundary.
