Abstract: An array substrate includes a substrate; scan lines and data lines arranged on the substrate and intersecting one another to define sub-pixels, each of which includes a pixel electrode including strip-like electrodes whose long axes of a same row are parallel to one another. Extension lines of long axes of strip-like electrodes in sub-pixels in any two adjacent rows intersect one another. The touch electrode is electrically connected to at least one touch signal line. Each touch signal line includes straight-line portions and fold-line portions. Two adjacent straight-line portions are connected by one fold-line portion. Any straight-line portion is parallel to long axes of strip-like electrodes in sub-pixels in a same row. Extension lines of fold-line portions intersect long axes of strip-like electrodes. Orthographic projections of fold-line portions on the substrate overlap orthographic projections of scan lines on the substrate. Fold-line portions are not perpendicular to scan lines.

Abstract: An array substrate and a display panel are provided. The array substrate includes a non-display area and a display area. The non-display area includes a first non-display area and a second non-display area, and the display area includes a normal display area and a wiring area. The normal display area is surrounded by the first non-display area, the wiring area is surrounded by the normal display area, and the second non-display area is surrounded by the wiring area. The second non-display area comprises an opening area. In the solution, since the number of data lead lines in the same layer in the wiring area is reduced, a line distance between adjacent data lead lines is increased, thereby reducing coupling capacitance between adjacent data lead lines arranged in the same layer.
