Abstract: A gate driver includes an input circuit, a pull-up circuit, a pull-down circuit, a QB node control circuit and a Q node control circuit. The input circuit transmits an input signal to a Q node in response to a first clock signal. The pull-up circuit pulls up a gate output signal to a high voltage in response to a signal of a QF node. The pull-down circuit pulls down the gate output signal to a low voltage in response to a QB node. The QB node control circuit controls a signal of the QB node based on a QB control signal and a second clock signal. The Q node control circuit controls a signal of the Q node based on the QB node.

Abstract: A light emitting display device includes multiple pixels arranged in multiple pixel rows, a first scan signal generator that provides a first scan signal to the pixels in the pixel rows, a second scan signal generator that provides a second scan signal to the pixels in the pixel rows, a third scan signal generator that provides a third scan signal to the pixels in the pixel rows, and a light emission signal generator that provides a light emission signal to the pixels in the pixel rows. Each of the second scan signal generator, the third scan signal generator, and the light emission signal generator provides a same signal to the pixels in two of the pixel rows.

Abstract: Provided is a light emitting display device comprising a driving transistor; a second transistor; a light emitting diode; a storage capacitor; a first scan line; and a driving gate electrode, in which a pixel includes only a transistor including an oxide semiconductor. The light emitting display device prevents deterioration of display quality due to a boost capacitor with a scan line in a pixel using an n-type transistor including an oxide semiconductor. Further, the light emitting display device prevents deterioration of display quality due to coupling with a data line in a pixel using an n-type transistor.
