Abstract: Devices and methods are provided to overdrive or underdrive a display panel to account for display pixel hysteresis due to several frames of pixel history. An electronic device may include an electronic display and processing circuitry. The electronic display includes a number of display pixels. The processing circuitry may generate image data for the display pixels. The processing circuitry may receive a current frame value of the image data targeted for a first display pixel and, based at least in part on the current frame value and a pixel history of the first display pixel—may indicate a gray level for a number of previous frames—generate a compensated value by which to drive the first pixel to overcome pixel hysteresis to reach the desired luminance at an initial response.
