Patent ID: 7224126

Claim:
A method for driving an organic light emitting display (OLED) panel including a plurality of organic light emitting diodes, wherein 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 method comprising: dividing the organic light emitting diodes electrically connected to the same common lines into a first group and a second group; and supplying driving currents to the organic light emitting diodes of the first group and the second group separately according to a first pulse width modulation (PWM) manner and a second PWM manner, wherein the first PWM manner and the second PWM manner have complementary waveforms in a period, and from a lowest grayscale to a highest grayscale, the waveforms of the first PWM manner are increased in length by measuring from a starting time of the period, and the waveforms of the second PWM manner are increased in length by measuring from an ending time of the period.
