摘要： 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.

摘要： A pixel includes an organic light emitting diode (OLED), a pixel circuit, and first and second transistors. The OLD includes a cathode electrode connected to a second power source. The pixel circuit includes a driving transistor having a gate electrode initialized by a third power source. The driving transistor controls the amount of current flowing from a first power source to the second power source via the OLED. The first transistor is connected between a fourth power source and the second power source and an anode electrode of the OLED. The first transistor is turned on based on a scan signal is supplied to a scan line. The second transistor is connected between a data line and the pixel circuit. The second transistor is turned on when the scan signal is supplied to the ith scan line.

摘要： A scan driver includes stages that include a first stage. A method for operating the scan driver includes providing a first clock signal, a first carry clock signal, a second carry clock signal, a first power source voltage, and a second power source voltage to the first stage to enable the first stage to provide a first scan signal to a first scan line. Throughout a portion of one frame, each of the first clock signal, the first carry clock signal, and the second carry clock signal is constant.
