Patent ID: 7965272

Claim:
An organic light emitting display, comprising: a display panel including a plurality of pixel circuits, a data line, and first and second scan lines; a bi-directional data driver adapted to apply a data signal in both directions; a first scan driver adapted to receive a forward or reverse signal and to selectively output a first selection signal in a forward or reverse direction to the first scan line in accordance with the forward or reverse signal, wherein the first scan driver includes: a scan direction controller adapted to receive the forward or reverse signal, and to cause a shift register of a next stage to generate a sequential signal in the forward or reverse direction, a shift register adapted to shift a start signal received by the scan direction controller to generate the sequential signal, a first selection signal supply section adapted to receive one of two adjacent signals, and first and second clock signals from the shift register and to provide the first selection signal to the first scan line; and a second scan driver adapted to receive the first selection signal and to selectively output a second selection signal in the forward or reverse direction to the second scan line in accordance with the forward or reverse signal.
