    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: 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: In an embodiment, a system may include one or more processors forming central processing units (CPUs) in the system, a display controller configured to display frames on a display device, a memory controller configured to control a memory, and a power management circuit. The power management circuit may be configured to establish one of a plurality of power states in the system. In a first power state, the display controller and the memory controller are powered on while the CPUs are powered off. The display controller may be configured to read a plurality of prerendered frames from the memory and display the plurality of prerendered frames at times specified for each of the plurality of prerendered frames.
