Patent number: 11640210Abstract: A touch panel includes a substrate, a raised structure, a touch sensing electrode layer, and a peripheral circuit layer. The substrate has a visible region and a border region surrounding the visible region. The raised structure is disposed on the substrate and located in the border region, in which the raised structure and the substrate constitute a step area. The touch sensing electrode layer is disposed in the visible region and partially extends to the border region to cross over the raised structure and cover the step area. The peripheral circuit layer is disposed in the border region, and overlaps the touch sensing electrode layer at least on the raised structure and the step area.Type: GrantFiled: November 27, 2020Date of Patent: May 2, 2023Assignee: TPK Advanced Solutions Inc.Inventors: Chien-Hsien Yu, Zi-Jun Ding, Yun-Guo Xu, Jian-Hua Fang, Li-De Lv
