Gate line driving circuit, display device having the same, and apparatus and method for driving the display device

摘要

In a gate line driving circuit, a display device, a driving apparatus and a driving method, a shift register sequentially shifts and outputs a high level data in response to a carry signal. A level shifter level-shifts an externally provided first voltage based on the high level data. An output buffer buffers the level-shifted first voltage and outputs the buffered level-shifted first voltage to a delay. The delay delays the buffered level-shifted first voltage and outputs the delayed level-shifted first voltage to a gate line. Thus, the delay applied to output stages of the gate line driving circuit act to delay the gate signal, thereby preventing deterioration of display quality caused by a kickback voltage.
