Abstract:
Disclosed herein is a light emitting period setting method for a display panel wherein the peak luminance level is varied through control of a total light emitting period length which is the sum total of period lengths of light emitting periods arranged in a one-field period, including a step of setting period lengths of N light emitting periods, which are arranged in a one-field period, in response to the total light emitting period length such that the period lengths of the light emitting periods continue to keep a fixed ratio thereamong, N being equal to or higher than 3.
