    Abstract: A pixel includes a pixel circuit and an organic light emitting diode. The pixel circuit has first, second, third, and fourth transistors. The first transistor controls an amount of current flowing from a first driving power supply coupled to a first node to a second driving power supply through the organic light emitting diode. The turns on when a scan signal is supplied to a first scan line. The third transistor turns on when a scan signal is supplied to a second scan line. The fourth transistor turns on when a scan signal is supplied to a third scan line. The first transistor is a p-type Low Temperature Poly-Silicon thin film transistor and the third transistor and the fourth transistor are n-type oxide semiconductor thin film transistors.

    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.
