Abstract: An array substrate and a display panel including the array substrate are provided. The array substrate has a display area and a fan-shaped wiring area. A first metal layer, a second metal layer, and a third metal layer are arranged in both the display area and the fan-shaped wiring area, and a fourth metal layer is arranged in the fan-shaped wiring area. In the display area, the first metal layer includes gate lines, the second metal layer includes data lines, and the third metal layer includes touch lines. Fingerprint identification signal lines are arranged in the fan-shaped wiring area and are electrically connected to fingerprint identification units arranged in the display area.

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.
