Abstract:
A GOA drive circuit includes a multiple stage of GOA drive units. A GOA drive unit includes a pre-pulldown unit which is configured to disconnect a discharge path of a first voltage signal via the pull-down sustaining unit before the first voltage signal jumps from a low electric potential to a high electric potential. In the GOA drive circuit, the voltage stability of the key nodes in a circuit and the reliability of the timing can be ensured; overall performance of the GOA drive circuit can be improved; and a service life of a display device can be prolonged.
