Abstract: A shift register unit circuit includes an input sub-circuit, a pull-up sub-circuit, a pull-down control sub-circuit, a pull-down sub-circuit, and a voltage regulating sub-circuit. The input sub-circuit receives an input signal from a signal input terminal to control a potential of a pull-up node. The pull-up sub-circuit outputs a gate driving signal to an output terminal under control of the potential of the pull-up node and a signal from a first signal terminal. The pull-down control sub-circuit conducts a pull-down node with a first node under control of a signal from the second signal terminal. The pull-down sub-circuit conducts the pull-up node with the first node and the turn-down signal terminal with the output terminal under control of a potential of the pull-down node. The voltage regulating sub-circuit conducts the first node with the turn-down signal terminal under control of a potential of the first node.

Abstract: A substrate in an array substrate includes a light aperture region and a winding region arranged around the light aperture region. On the substrate, an orthographic projection of a first winding in each first signal line is overlapped with an orthographic projection of a second winding in a corresponding second signal line. In this way, the distance between two adjacent signal lines in the winding region is larger, and the parasitic capacitance generated between them is smaller.
