Patent number: 11625135Abstract: A touch sensor includes a first sensing electrode unit formed on a substrate in a first direction and a second sensing electrode unit formed on the substrate in a second direction crossing the first direction. A plurality of micro-etched patterns are formed on a boundary of unit transparent electrodes constituting the first sensing electrode unit and the second sensing electrode unit. The unit transparent electrode has a shape in which a portion of a curve connecting vertices of a polygon is removed, and adjacent unit transparent electrodes are electrically connected to each other. It includes a segmental pattern dividing the first or second sensing electrode unit into two or more areas.Type: GrantFiled: February 15, 2022Date of Patent: April 11, 2023Assignee: DONGWOO FINE-CHEM CO., LTD.Inventors: Dohyoung Kwon, Cheol Hun Lee
