Abstract:
1. A method for preparing an electronic display of an electronic device to be turned off comprising: receiving at the electronic display an indication of an imminent electronic display reset signal from a power management unit, a processor, or some combination thereof indicating the electronic display will be powered off within a period of time; in response to the indication of an imminent electronic display reset signal, causing a frame of pixel data originating from the electronic display to be stored in pixels of the electronic display before the electronic display is powered off to inhibit image artifacts from occurring on the electronic display when the electronic display is powered back on in the future; outputting a feedback signal from the electronic display to a component of the electronic device after the frame of pixel data is stored in the pixels of the electronic display, wherein the feedback signal indicates that the electronic display may be powered down without a residual bias voltage on the pixels of the electronic display; and receiving an electronic display reset signal from the power management unit, the processor, or some combination thereof of an electronic display reset before the electronic display is forced off.
