Title: GOA DRIVE CIRCUIT
Abstract:
A GOA drive circuit comprises a multi-stage GOA drive unit. The GOA drive unit comprises a pre-charging/pull-down unit (25). The pre-charging/pull-down unit (25) is configured to turn off a path in which a first voltage signal (Q node voltage) performs discharging by means of a pull-down sustaining unit (24) before a potential of the first voltage signal (Q node voltage) jumps from a low level to a high level. The GOA drive circuit ensures voltage stability at a key node therein and reliability of a timing sequence, thereby improving overall performance of the GOA drive circuit, and facilitating extension of service life of a display device.
