Patent number: 11036099Abstract: An array substrate includes non-touch-signal-transmitting lines that do not have a function of transmitting a touch signal. The non-touch-signal-transmitting lines are parallel with data lines. By connecting the non-touch-signal-transmitting lines with scan lines, the non-touch-signal-transmitting lines may provide electrical connection between the scan lines and a scan line driving circuit so that the scan line driving circuit and a data line driving chip can be arranged on a same one of edge frame parts or two opposite ones of the edge frame parts. Thus, the other ones of the edge frame parts are allowed to have a width of only 0.1-0.3 mm, making it possible to achieve ultra slimming of edge frame for at least two of the edge frame parts.Type: GrantFiled: January 30, 2018Date of Patent: June 15, 2021Assignee: WUHAN CHINA STAR OPTOELECTRONICS TECHNOLOGY CO., LTD.Inventor: Chengao Yang
