Patent ID: 8922466

Claim:
A display panel driving method of the type wherein the total light emitting period length within each of a plurality of one-field periods is controlled to variably control the peak luminance level of a display panel, said driving method comprising: variably controlling, for a first one-field period that has N light emitting periods per writing period disposed therein, N being equal to or greater than 2, the light emitting period length of a first particular one of the light emitting periods and the other light emitting period or periods to provide a difference in luminance between the first particular light emitting period and the other light emitting period or periods so that the first particular light emitting period is visually observable, and variably controlling, for a second one-field period that has N light emitting periods per writing period disposed therein, N being equal to or greater than 2, the light emitting period length of a second particular one of the light emitting periods and the other light emitting period or periods to provide a difference in luminance between the second particular light emitting period and the other light emitting period or periods so that the second particular light emitting period is visually observable, wherein the first particular light emitting period and the second particular light emitting period have different lengths.
