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: A device may include an electronic display to display an image frame based on first and second color component input image data. The electronic display may include a first illuminator to generate a first light at a first brightness level, a second illuminator to generate a second light of a different color at a second brightness level, a first set of pixel locations to emit the first light based on a first set of pixel values, and a second set of pixel locations to emit the second light based on a second set of pixel values. The electronic device may also include pixel contrast control circuitry that determines the first brightness level and the first set of pixel values based on the first color component input image data and determines the second brightness level and the second set of pixel values based on the second color component input image data.
