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.

The invention relates to the field of examination beds, and discloses an examination bed for the anorectal department. A bed surface unit; the clamping mechanism comprises a U-shaped groove base, and an inner cavity of the U-shaped groove base is provided with a buffering air bag capable of being inflated and expanded; the health protection assembly comprises a roll feeding mechanism and a rolling mechanism which are arranged in the two sides of the clamping mechanism respectively, a disposable protective film is wound on the roll feeding mechanism, and the disposable protective film spans the surface of the buffering air bag and extends to the rolling mechanism; the stretching deformation amount of the film is reversely deduced through the air displacement of the buffer air bag, and the rolling step length is dynamically compensated through a correction algorithm, so that the rolling length is accurately matched with the actual film consumption. The mechanism solves the problem of film surface residue caused by the change of the expansion degree of the air bag in the traditional fixed-length rolling, ensures that a new film is completely exposed in a working area after the film is replaced every time, and eliminates the hidden danger of cross infection from the physical level.
