A gate drive circuit having a self-compensation function, comprising: a plurality of cascaded GOA units, charging of an Nth level horizontal scanning line G (N) of a display area being controlled according to an Nth level GOA unit, the Nth level GOA unit comprising: a pull-up control module (1), a pull-up module (2), a transfer-down module (3), a first pull-down module (4), a bootstrap capacitance module (5) and a pull-down holding module (6). The pull-up module (2), the first pull-down module (4), the bootstrap capacitance module (5) and the pull-down holding module (6) are respectively electrically connected to an Nth level gate signal point Q (N) and the Nth level horizontal scanning line G (N), the pull-up control module (1) and the transfer-down module (3) are respectively electrically connected to the Nth level gate signal point Q (N), and the pull-down holding module (6) inputs a first direct current low voltage VSS1 and a second direct current low voltage VSS2. The drive circuit improves the reliability of a long-term operation of the gate drive circuit via the pull-down holding module (6), said module having a self-compensation function. A pull-down holding module (6) directly controlled by a set of direct current signal sources DC may also be designed, saving circuit layout design space and reducing overall power consumption of the circuit. |
