Abstract
An array substrate includes a driving circuit arranged on the base substrate, and the driving circuit includes a pull-up node control circuit, a first pull-down node control circuit, and an output circuit; the pull-up node control circuit controls a potential of the pull-up node; the first pull-down node control circuit controls to write a first control voltage provided by the first control voltage line into the first pull-down node; the output circuit controls the driving signal output terminal to output a driving signal under the control of the potential of the pull-up node; the array substrate also includes a first conductive portion arranged on the base substrate; the first conductive portion is electrically connected to the first control voltage line.
