Abstract
A gate drive circuit is disclosed. The drive circuit includes M cascaded shift registers, where M is a natural number, and a clock controller configured to generate two reverse-phase clock signals. The drive circuit also includes a high level controller configured to generate a high level signal, and a low level controller configured to generate a low level signal, where one of the high level controller and the low level controller is configured to generate an initial pulse signal during an initial stage. The drive circuit also includes a start unit cascaded with the M shift registers, where the start unit is configured to provide a start signal to the shift registers.
