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.
