Patent number: 10580803Abstract: 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.Type: GrantFiled: October 18, 2018Date of Patent: March 3, 2020Assignee: XIAMEN TIANMA MICRO-ELECTRONICS CO., LTD.Inventors: Liangliang Bei, Huangyao Wu, Xuexin Lan, Hongbo Zhou, Yihua Zhu, Guochang Lai, Guozhao Chen
