Gate driver and related circuit buffer

A gate driver, for outputting a voltage signal, the gate driver comprising:

• a plurality of circuit buffers, comprising:
• a first circuit buffer, comprising:
• a first power supply terminal, for receiving a first voltage;
• a second power supply terminal, for receiving a second voltage;
• an input terminal, for receiving a first input signal;
• and
• an output terminal, for outputting the voltage signal according to the first voltage, the second voltage and the first input signal;
• a second circuit buffer, comprising:
• a third power supply terminal, for receiving a third voltage;
• a fourth power supply terminal, electrically connected to the input terminal of the first circuit buffer, for receiving the first input signal;
• an input terminal, for receiving a second input signal;
• and
• an output terminal, electrically connected to the first power supply terminal, for outputting the first voltage to the first circuit buffer according to the third voltage, the first input signal and the second input signal;
• and
• a third circuit buffer, comprising:
• a fifth power supply terminal, electrically connected to the input terminal of the first circuit buffer, for receiving the first input signal;
• a sixth power supply terminal, for receiving a fourth voltage;
• an input terminal, for receiving a third input signal;
• and
• an output terminal, electrically connected to the second power supply terminal, for outputting the second voltage to the first circuit buffer according to the first input signal, the fourth voltage and the third input signal;
• wherein the first voltage, the second voltage, the third voltage and the fourth voltage are switched between two different voltage levels, and an amplitude of the voltage signal is greater than a withstand voltage of any circuit element in the gate driver.
