Abstract
A gate drive circuit includes a plurality of gate drive units. Each of the gate drive units includes a stage transmission signal selection circuit, a pull-up control circuit, a pulse number reduction circuit, a first inversion circuit, a first output stage, and a second output stage, and can output a second gate control signal with a greater number of pulses and a first gate control signal with a less number of pulses. At least one of the stage transmission signal selection circuit, the first inversion circuit or the second output stage includes three transistors with the same channel type.
