ABSTRACT:
A high voltage gate driver circuit according to an embodiment of the present invention controls an operational range of an output signal of a level shifter to be appropriate for an operational range of a reshaper through a VIV converter. Even though the voltage range of the signal which is input from the high voltage gate driver circuit to the level shifter is different from the operational range of the reshaper, the input signal can always be recognized exactly regardless of the VTH voltage of the reshaper by controlling the operational range of the signal through the VIV converter. In addition, incorrect operation of the circuit can be prevented by erasing a common mode noise which is input with the input signal.
