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: Electronic devices, displays, and methods are provided for performing row shuffling to reduce an appearance of image artifacts during eye movements such as saccades. An electronic display may include a number of rows of display pixels and driving circuitry to drive the rows of pixels. The driving circuitry may spatially shuffle or temporally shuffle, or both spatially and temporally shuffle, a row order of driving the rows of display pixels.

Abstract: A control circuit adjusts a value of a source supply voltage VSSEL provided to a display area in an electronic display. The control circuit also adjusts a voltage Vreset applied to the display area to cause the display area to emit light more uniformly under various ambient conditions (e.g., temperature) surrounding the display area. Dynamically changing Vreset is employed to make anode charging dynamics independent of temperature. The control circuit adjusts the source supply voltage VSSEL and the voltage Vreset together to compensate display pixel hysteresis effects and display artifacts caused by temperature changes and brightness changes of the display area and collectively produce images. Dynamically tuning the Vreset and the VSSEL voltages also saves power and improves gray level accuracy for the electronic display.
