Publication number: 20220357813Abstract: A touch sensor having a visible area and a peripheral area at least on one side of the visible area includes a substrate, a touch electrode layer, and peripheral traces. The touch electrode layer is disposed on a surface of the substrate and includes touch electrodes corresponding to the visible area. The peripheral traces are disposed on the surface of the substrate and corresponding to the peripheral area. The peripheral traces are respectively electrically connected to the touch electrodes. Each of the peripheral traces includes a matrix and metal nanowires distributed in the matrix. A line width of each of the peripheral traces is more than or equal to 6 ?m and less than or equal to 12 ?m, and a line spacing of any adjacent peripheral traces of the peripheral traces is more than or equal to 6 ?m and less than or equal to 12 ?m.Type: ApplicationFiled: May 10, 2021Publication date: November 10, 2022Inventors: Shao Jie Liu, Qin Xue Fang, Xue Long Zhang, Mei Fang Lan, Wei-Chia Fang, En-Chia Chang, Xiao Ping Guo

Patent number: 11487369Abstract: A touch panel having dummy pattern is provided, including a first metal nanowire layer and a second metal nanowire layer. The first metal nanowire layer includes first electrode wires, first axial wires connected to the first electrode wires, and first dummy patterns. The second metal nanowire layer includes a plurality of second electrode wires and a plurality of second axial wires connected to the second electrode wires. The first dummy patterns are electrically insulated and deposited outside the first electrode wires and the first axial wires, and each of the first dummy patterns comprises a plurality of first etching areas extending along the first and second directions. The first dummy patterns do not expose the first etching areas along the first direction at a vertical projection area of a part where each of the second axial wires alone exists, so that the electrode pattern is difficult to observe.Type: GrantFiled: April 7, 2021Date of Patent: November 1, 2022Assignee: TPK Advanced Solutions Inc.Inventors: Qin-Xue Fang, Xiang-Xing Xu, Yong-Bin Ke, Yi-Peng Gan, Li-Huang Tsai
