US 2018/0005573 A1 · STAGE AND ORGANIC LIGHT EMITTING DISPLAY DEVICE USING THE SAME

Abstract

A stage includes first, second, and third outputs and first and second signal processors. The first output supplies a scan signal to a first output terminal based on signals to first and second input terminals and the voltage of a first node. The second output is connected to a first power source and supplies an emission control signal to a second output terminal based on signals to the first input terminal, the first output terminal, and a third input terminal. The third output is connected to the first power source and supplies an inverted emission control signal to a third output terminal based on signals to the first input terminal and second output terminal. The first signal processor controls the first node voltage based on a signal to a fourth input terminal. The second signal processor controls the first node voltage based on the signal to the second input terminal.
