ABSTRACT:
An organic light emitting display (OLED) panel has a plurality of organic light emitting diodes. The organic light emitting diodes are electrically connected to a plurality of segment lines and a plurality of common lines in a matrix structure. The organic light emitting diodes electrically connected to the same common lines are divided into a first group and a second group. Driving currents are separately supplied to the organic light emitting diodes of the first group and the second group according to a first pulse width modulation (PWM) manner and a second PWM manner. The first PWM manner and the second PWM manner have complementary waveforms in a period.
