Abstract
Disclosed is an OLED PWM pixel driving method. The method comprises: slicing a frame of image into a plurality of subfields different in weight, and splitting a subfield having a higher weight thereamong into secondary subfields in a predetermined splitting ratio; and rearranging the split secondary subfields from the subfield having a higher weight and non-split subfields according to an input image and the predetermined splitting ratio in order to eliminate an image display error.
