Abstract: An electronic device may include a display panel. When content of an image frame is expected to consume relatively higher amounts of power, a controller of the electronic device may operate a switch to change a power supply of the display panel to be a power management integrated circuit of the electronic device. However, when content of an image frame is expected to consume relatively less amounts of power, the controller may operate the switch to change the power supply of the display panel to be a power supply of an electronic display, such as a power supply used to power driver circuitry of the electronic display.

Abstract: An electronic device may include processing circuitry configured to generate a first frame of image content and a second frame of image content. The second frame of image content is different from the first frame of image content. The electronic device may also include a display configured to display the first frame of image content at a first refresh rate. In response to receiving the second frame of image content, the electronic device may initially increase the refresh rate before tapering back to the first refresh rate while displaying the second frame of image content.

Abstract: Systems, methods, and devices are provided to selectively perform a frame replay at various stages of an image processing pipeline for an electronic display. Image processing circuitry may include first compensation circuitry that compensates for a first compensation factor relating to a first physical parameter of an electronic display and second compensation circuitry that compensates for a second compensation factor relating to a second physical parameter of the electronic display. A first tap point that enables the image frame to be stored and reused may be located between the first compensation circuitry and the second compensation circuitry, while a second tap point may be located after the second compensation circuitry.

Abstract: An electronic device may include a display and image processing circuitry. The image processing circuitry may receive a frame of image data for display by the display and at least one external display coupled to the electronic device, where the frame of image data comprises an active portion and an idle portion, wherein the active portion comprises data for presenting one or more images via the display and the at least one external display, receive a signal from a controller during the idle portion of the frame of image data, and initiate processing of a first line of active portion in response to receiving the signal. In this way, the frame of image data being displayed by the display and the at least one external display may be in sync.

Abstract: A light emitter that operates through a display may cause display artifacts, even when the light emitter operates using non-visible wavelengths. Display artifacts caused by a light emitter that operates through a display may be referred to as emitter artifacts. To mitigate emitter artifacts, operating conditions for a display frame may be used to determine an optimal firing time for the light emitter during that display frame. The operating conditions used to determine the optimal firing time may include emitter operating conditions, display content statistics, display brightness, temperature, and refresh rate. Operating conditions from one or more previous frames may be stored in a frame buffer and may be used to help determine the optimal firing time for the light emitter during a display frame. Pixel values for the display may be modified to mitigate emitter artifacts.
