摘要:
An organic light emitting display device includes an organic light emitting display panel, and a driver that drives the organic light emitting display panel. The driver applies a first power voltage and a second power voltage to the organic light emitting display panel, the first power voltage is lower than the second power voltage during a first period, and the first power voltage is higher than the second power voltage during a second period.
