摘要:
Methods and devices employing circuitry for quickly discharging pixels of a display before the display is turned off are provided. In one example, a method may include receiving at the electronic display a signal indicating the electronic display will be powered off within a period of time. The method may also include, in response to the 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. Storing the frame of pixel data in the pixels may inhibit image artifacts from occurring on the electronic display when the electronic display is powered back on in the future.
