    • An apparatus and method for driving an organic light emitting display so as to minimize or prevent a raindrop phenomenon and an afterimage is provided. The apparatus and method determines the driving state of a pixel unit by using a vertical sync signal, and turns on or off the determined driving state of the pixel unit. The supply of the power voltage is sustained when the pixel unit is driven, and is turned off when the pixel unit is not driven. Accordingly, the apparatus and method can minimize or prevent a raindrop phenomenon and an afterimage by turning off the supply of the power voltage when the pixel unit is not driven.
    • 提供了一种用于驱动有机发光显示器以最小化或防止雨滴现象和余像的装置和方法。 该装置和方法通过使用垂直同步信号来确定像素单元的驱动状态,并且打开或关闭所确定的像素单元的驱动状态。 当像素单元被驱动时,电源电压的供应是持续的,并且当像素单元未被驱动时,该电源电压被关闭。 因此,该装置和方法可以通过在不驱动像素单元时关闭电源电压的供给来最小化或防止雨滴现象和残影现象。
