PLASMA DISPLAY PANEL AND METHOD FOR PROCESSING PICTURES THEREOF

摘要

A plasma display device and an image processing method thereof for reducing false contour and avoiding a low discharge at grayscales include detecting a moving image block and a still image block from input video signals. The output of grayscales of the detected still image block is determined such that the number of consecutive non-lighting subfields is less than L among fields driven previously to a last turn-on subfield of the corresponding output grayscale. The output grayscale of the detected moving image block is determined such that a number of consecutive non-lighting subfields is less than or equal to M and the total of non-lighting subfields is less than or equal to N among fields driven previously to a last turn-on subfield of a corresponding output grayscale.
