Patent ID: 6897836

Claim:
A method of driving a display panel for each group of subfields defining one field of a video signal, the each group of subfields being arranged from a front subfield to a last subfield, the display panel including a plurality of row electrodes and a plurality of column electrodes intersecting with the plurality of row electrode such that a light emissive cell is formed at each intersection of the plurality of row electrodes and the plurality of column electrodes, comprising: A) determining a light emission weight of each subfield and a combination of light emitting subfields at each gradation level such that the number of subfields having different light emission states between two adjacent gradation levels is less than a predetermined value; B) providing a plurality of field display sequences such that the combinations of the light emitting subfields at at least one gradation level are different from each other between the plurality of field display sequences; and C) sequentially displaying a plurality of fields by changing a currently used field display sequence to another field display sequence each time a predetermined number of fields of the video signal are displayed.
