Abstract:
The present disclosure discloses a gate drive circuit, a display panel and a driving method for the gate drive circuit. The gate drive circuit includes a plurality of shift register units connected in cascade; and further includes: buffer units which are in a one-to-one correspondence with shift register units at all levels, and touch control switch units which are in a one-to-one correspondence with shift register units at even levels. Each buffer unit in the gate drive circuit can increase the holding time of the effective pulse signal output by the shift register unit at a corresponding level by one line before resetting, and the effective pulse signal output by a buffer unit at an even level under the control of a touch control unit and the effective pulse signal output by a buffer unit at an adjacent previous odd level are reset at the same time.
