Patent ID: 7576714

Claim:
A method for driving a display panel on which a plurality of pixel cells are formed, in each of a plurality of subfields to which a number of times or a period for causing each of the pixel cells to emit light is allocated, said plurality of subfields defining a single field of an input picture signal, said method comprising the steps of: causing the pixel cells to emit light in each of a number of subfields corresponding with a luminance level indicated by the input picture signal in each field; and controlling the number of light emissions or the light emission period in which the pixel cells are caused to emit light in each field by changing the number of the subfields that are to be allocated to a luminance level lower than a predetermined luminance in the input picture signal, in accordance with a peak luminance level of each field of the input picture signal, wherein a total number of the subfields constituting each field and a maximum number of light emissions in one field are constant irrespective of the peak luminance level.
