Abstract
The invention relates to a method for reducing imaging artifacts during a frame-changeover from a current frame to a following frame displayed by a display device comprising a plurality of pixels, wherein the artifacts are reduced by overdriving at least one control signal for controlling the pixel intensity of the related pixel during the frame-changeover, wherein the overdrive is carried out in dependence of the magnitude of an intensity step between a designated start intensity value of the pixel within the current frame and a designated target intensity value of the pixel within the following frame.
