Abstract
A touch panel includes a sensing layer, which has a plurality of sensing lines extending along a first direction and arranged in a row along a second direction. Each of the sensing lines individually has a first end and a second end electrically connected to a detecting circuit respectively, and the detecting circuit computes a coordinate in the first direction of a touch position in accordance with voltage variation at the first and second ends of the sensing line.
