    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 a display panel to display images based on corresponding image data and an image source to pre-render a flip-book including a first image frame for display at a first target presentation time and a second image frame for display at a second target presentation time. The electronic device may also include a display pipeline coupled between the display panel and the image source having image data processing circuitry to process image data for display. The electronic device may also include a controller to instruct the display pipeline to process image data, to determine a power-on time based on a target presentation time, and to instruct the display pipeline to power-gate the image data processing circuitry upon completion of the processing of image data and until the power-on time is reached.

    Abstract: In situations with reduced image changes, display panels, such as the ones disclosed herein, may reduce their power consumption by performing self-refresh cycles, in which they may display locally stored data in the display panel instead of retrieving it from an image buffer. Methods and circuitry for management of the self-refresh cycle may reduce jitter, luminance errors, and/or flickers that may be caused by untimely self-refresh cycles that may occur as a result of latency in the image buffer. In some implementations, the display panel may have a dedicated low latency input that notifies an arrival of an incoming image. In some implementations, the self-refresh cycles of the panel may be managed by a host or a buffer that is responsible for sending the images.
