Abstract
Disclosed is a GOA drive circuit, which includes multiple stages of GOA drive units. A pull-down unit of a GOA drive unit in each stage is configured to increase a time for a first voltage signal to be pulled down to a first electric potential during a process when the first voltage signal jumps from a high electric potential to a low electric potential, so as to enable the first voltage signal to have a stepwise falling edge. In the GOA drive circuit, smoothness of a voltage at a key node thereof during a voltage changing process can be ensured, whereby an output performance of the GOA drive circuit can be improved, and an overall performance thereof can be improved accordingly.
Claims16
A GOA drive circuit, comprising multiple stages of GOA drive units, wherein a GOA drive unit in each stage is used for outputting a row scan signal to a row of pixel units and comprises a pull-up unit, a pull-up control unit which outputs a first voltage signal, a transmission unit, a pull-down unit, and a pull-down maintenance unit,
- wherein the pull-down unit is configured to increase a time for the first voltage signal to be pulled down to a first electric potential during a process when the first voltage signal jumps from a high electric potential to a low electric potential, so as to enable the first voltage signal to have a stepwise falling edge.
