<p>Provided are a gate drive circuit, an array substrate of same, and a display panel. The gate drive circuit comprises multiple levels of gate drive units, each level of gate drive unit comprising a start unit (10) for transmitting a start signal (STV), an energy storage unit (20) for executing charging according to the start signal (STV) to output a drive voltage (Q), a pull-up unit (30) working under the drive voltage (Q), a first and a second pull-down unit (40, 50), and a third pull-down unit (60). The third pull-down unit (60) is used to pull the drive voltage (Q) down to a second reference voltage (VSS2) during vertical retracing , so as to apply a reverse bias on the gate and source and/or the gate and drain of a transistor in the gate drive circuit; in this way, a negative offset occurs in a threshold voltage, having a positive offset, of a transistor, thereby effectively alleviating a bad effect of the threshold voltage offset of the transistor on the gate drive circuit, and improving working reliability of the gate drive circuit, the array substrate of same, and the display panel.</p> |
