PURPOSE: An organic light emitting display and a driving method thereof are provided to implement the threshold voltage compensation of a driving transistor and high speed operation by driving pixels in a synchronous lighting mode. CONSTITUTION: A pixel unit comprises a pixel(140) The pixels are connected to scanning lines, control lines, and data lines. A control line driving unit supplies a control signal to each pixel. A power control unit supplies different levels of power sources to the pixels during one frame. A control signal and power source are simultaneously applied to all pixels. |
