Abstract: 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.

Abstract: 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.
