Abstract
Disclosed is a driving method and a driving system for reducing a residual image of AMOLED display. The driving method includes: performing a high contrast edge detection on a static picture; determining an edge contrast of each pixel based on a result of the edge detection; adjusting an output luminance proportional coefficient of each pixel based on the edge contrast of each pixel and a position of each pixel itself; and outputting a luminance of each pixel by the output luminance proportional coefficient corresponding to each pixel. The driving method can improve the bright and dark difference ratio of the edge contours in the high contrast region of the image.
