    Abstract: An electronic device includes a display panel and image processing circuitry. The image processing circuitry receives input image data corresponding to an image to display on the display panel, modifies the input image data by executing a first context task (e.g., lower priority task), and receives a context switch request. The image processing circuitry also pauses modification of the input image data by pausing execution of the first context task and then switches to modifying the input image data by executing a second context task (e.g., higher priority task).

    Abstract: Embodiments provide for a display system to generate and display data on a display device, the display system comprising one or more graphics processors to generate one or more frames of data for display on the display device; a display engine to present the one or more frames of data to the display device for display; display logic to receive a request to display the one or more frames of data and generate one or more display events for the display engine based on the request, wherein the request includes a first hint to indicate a complexity of the one or more frames of data and the one or more display events includes a second hint derived from the first hint; and a performance controller to adjust one or more performance related parameters for the display system based on the second hint.

    Abstract: Systems, methods, and non-transitory media are presented that provide for improving color accuracy. An electronic display includes a display region having multiple pixels each having multiple subpixels. The electronic device also includes a display pipeline coupled to the electronic display. The display pipeline is configured to receive image data and perform white point compensation on the image data to compensate for a current drop in the display to cause the display to display a target white point when displaying white. The display pipeline also is configured to correct white point overcompensation on the image data to reduce possible oversaturation of non-white pixels using the white point compensation. Finally, the display pipeline is configured to output the compensated and corrected image data to the electronic display to facilitate displaying the compensated and corrected image data on the display region.

    Abstract: An electronic device may include a display panel and processing circuitry. The display panel may display frames of image data having a static border that remains the same across multiple frames and a dynamic border that changes between a first frame and a second frame. The processing circuitry may apply a static gain value set from a static gain map to pixels to reduce or eliminate aliasing image artifacts along the static border. The processing circuitry may also apply a changing gain value set from a dynamic gain map to pixels to reduce or eliminate aliasing image artifacts along the dynamic border.
