Abstract:
A gate driver for driving a display device in accordance with driving signals, comprising:a voltage level shift circuit which receives a data signal, an output enable signal and an output driver control signal each having a voltage level defined by a difference between a high-signal voltage and a low-signal voltage, and which increases the voltage level of the data signal, the output enable signal and the output driver control signal to output a voltage level shifted data signal, a voltage level shifted output enable signal and a voltage level shifted output driver control signal; an output circuit which receives the voltage level shifted data signal and which outputs the driving signals corresponding to the voltage level shifted output driver control signal in response to the voltage level shifted output enable signal; wherein said output circuit outputs a plurality of the driving signals in parallel and comprises: a plurality of shift registers each of which stores the voltage level shifted data signal, and each of which outputs the stored data signal in response to the voltage level shifted output enable signal; and a plurality of output drivers which outputs the driving signals corresponding to the stored data signals.
