Abstract: The present disclosure relates to a pixel displaying an image. A pixel includes an organic light emitting diode, a first transistor controlling an amount of current flowing from a first driving power supply to a second driving power supply via the organic light emitting diode in response to a voltage of a first node; a storage capacitor connected between the first node and the first driving power supply; a second transistor connected between a data line and the first node and turned on when a scan signal is supplied to a first scan line, and an auxiliary transistor connected between the second transistor and the data line and turned on when a scan signal is supplied to a second scan line. The second transistor and the auxiliary transistor have an overlapping turn-on period, and the second transistor is turned off before the auxiliary transistor is turned off.

Abstract: A stage includes an output, an input, signal processors, and a stabilizer. The output supplies a voltage of a first or second power source to an output terminal based on voltages of first and second nodes. The input controls voltages of third and fourth nodes based on signals to a first and second input terminals. A first signal processor controls the voltage of the first node based on the voltage of the second node. A second signal processor is connected to a fifth node and controls the voltage of the first node based on a signal to a third input terminal. A third signal processor controls the voltage of the fourth node based on the voltage of the third node and the signal to the third input terminal. The stabilizer is connected between the second signal processor and input to control voltage drop widths of the third and fourth nodes.
