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.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to an array substrate and a display device. Background technique [0002] In the field of liquid crystal display technology, in-plane switching (In-Plane Switching IPS) technology and fringe field switching (Fringe Field Switching FFS) technology are two commonly used wide viewing angle liquid crystal display technologies, which are characterized by pixel electrodes and common electrodes. It is arranged on the same substrate to make the liquid crystal molecules rotate in a plane parallel to the substrate, thereby improving the light transmission efficiency of the liquid crystal layer. Especially in the field of liquid crystal display technology with built-in touch, based on IPS or FFS technology, using mutual capacitance or self-capacitance mode to divide common electrodes into touch blocks for time-sharing touch technology has become the mainstream.
