Abstract
Embodiments of the present invention provide a gate driver circuit, a touch display device and a touch display driving method. The gate driver circuit includes a plurality of GOA unit groups arranged successively and control units arranged between every two adjacent GOA unit groups, each of the GOA unit groups comprising a plurality of shift registers which are cascaded. The control unit is configured to output a start control signal at a high level to a signal input end of a first stage shift register of a next GOA unit group corresponding thereto, after a last stage shift register of a previous GOA unit group corresponding thereto completes driving for a corresponding gate line and a predetermined time elapses, so as to pre-charge the first stage shift register of the next GOA unit group.
