Abstract:
A method of driving a display panel for performing gray-scale drive of a display panel employing a matrix display scheme, the display panel having a plurality of pixel cells each formed at an intersection of a plurality of electrode rows arranged for each of the scanning lines and a plurality of electrode columns arranged so as to intersect said electrode rows, comprising a step of:executing a division light-emission drive process for causing selected ones of said pixel cells to emit light for a number of light emissions assigned to each of a plurality of divided display periods forming a unit display period of an input video signal, wherein a number of executions of said division light emission drive process within said unit display period is changed in response to a vertical synchronization frequency of said input video display, and wherein said unit display period corresponds to a display period of two fields of said input video signal, and the number of execution of said division light-emission drive process is changed in one of said two fields of said input video signal.
