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, a display panel and a display device are disclosed. The array substrate includes a base substrate, and a bias voltage applying circuit and a plurality of semiconductor pressure sensors both disposed at a side of the base substrate. The bias voltage applying circuit is electrically connected to a first power supply signal inputting terminal and a second power supply signal inputting terminal of the semiconductor pressure sensor via a first power supply signal line and a second power supply signal line, respectively, to supply a bias voltage to the semiconductor pressure sensor. A concentration of the dopant ions is higher when the related semiconductor pressure sensor is closer to the bias voltage applying circuit, so that an electrical resistance value of said semiconductor pressure sensor is lower.

Abstract: A display panel and a display device are provided. The display panel includes multiple pixel units. In each of the pixel units, the area of an opening region of at least one sub-pixel is different from the area of an opening region of other sub-pixels. There is an adjustment capacitance between the drain of the thin film transistor and/or the first electrode in each sub-pixel and the scan line corresponding to the sub-pixel, and the sub-pixel having a smaller area of the opening region corresponds to a smaller value of the adjustment capacitance. By adjusting the value of the adjustment capacitance corresponding to the sub-pixels with different areas of opening regions, the optimal Vcom of all the sub-pixels is the same, so that all the sub-pixels operate under the same optimal Vcom.

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.
