Abstract
Embodiments herein describe techniques for mitigating or preventing image sticking in a display screen (e.g., a LCD or plasma display). In one embodiment, the pixels in the display screen are assigned to different groups. During a first time period, the display turns off a subset of the pixels in each of the groups. De-energizing the pixel mitigates or removes the reversed voltage that creates image sticking. During another time period, another subset of pixels in each of the groups is de-energized while the pixels that were de-energized in the previous time period are energized.
