Title
(EN) Scanning driving circuit, array substrate and display panel
(ZH) 扫描驱动电路、阵列基板与显示面板
Abstract
(EN)
The invention discloses a scanning driving circuit, an array substrate with the scanning driving circuit, and a display panel. The scanning driving circuit comprises a pull-up unit and a bootstrapping unit which are arranged on the surface of a substrate. The pull-up unit comprises a pull-up thin-film transistor which is used for outputting a scanning driving signal. The bootstrapping unit comprises a bootstrapping capacitor which is electrically connected with the pull-up thin-film transistor and is used for sustaining stability of the scanning driving signal. The pull-up thin-film transistor comprises a gate electrode, a first insulating layer, a source electrode and a drain electrode, wherein the gate electrode, the first insulating layer, the source electrode and the drain electrode are successively laminated on the surface of the substrate. The bootstrapping capacitor comprises a first conductive electrode and a second conductive electrode. The first conductive electrode and the source electrode are arranged in the same layer and are electrically connected with each other. A second insulating layer is arranged between the second conductive electrode and the second electrode. The second conductive electrode is electrically connected with the gate electrode through a first via. The first via penetrates through the second insulating layer and the first insulating layer.
