ABSTRACT:
The present invention provides a gray scale display method and apparatus that can be used with a large screen plasma display panel to perform illumination in a binary manner while substantially controlling flicker effects. The gray scale can be displayed by combining illumination and non-illumination periods in each of a plurality of subfields, the subfields being defined by at least a first block and a second block which have different structures. The plurality of subfields are arranged so that the luminance value of each subfield is in an ascending or descending order in the blocks.
