Abstract:
1. A display panel driving method of the type wherein the total light emitting period length within a one-field period is controlled to variably control the peak luminance level of a display panel, said display panel including a light emitting timing determination section and a supplemental scanning line driving section, comprising the step of: variably controlling, where the one-field period has N light emitting periods per writing period, N being equal to or greater than 2, the end timing of the ith light emitting period and the start timing of the i+1th light emitting period so as to satisfy the total light emitting period length within the one-field period, i being an odd number which satisfies 1≦i≦N−1 while i+1 satisfies 2≦i+1≦N, and supplying, by the light emitting timing determination section, a start pulse for providing a start timing of each light emitting period and an end pulse for providing an end timing of each light emitting period to the supplemental scanning line driving section, wherein said variably controlling further includes controlling the total light emitting period length to narrow a gap between the ith light emitting period and the i+1th light emitting period from the opposite directions, by adjusting both an end timing of the ith light emitting period and a start timing of the i+1th light emitting period.
