Abstract
A gate driver comprises an ith stage gate driver circuit including a latch circuit and a first output circuit. The latch circuit includes a first input for receiving an (i−1)th gate signal, a second input for receiving a first clock signal, a first output for outputting a first output signal, and a second output for outputting a second output signal. The first output circuit comprises a first transistor, a second transistor and a capacitor. The first transistor includes a control terminal coupled to the first output, a first terminal coupled to a first clock input and a second terminal coupled to a first output node. The second transistor includes a control terminal coupled to the second output, a first terminal coupled to the first output node and a second terminal coupled to a reference signal. The capacitor is coupled between the first transistor and the first output node.
