A touch panel connected to a control circuit and includes a substrate, at least one first sensing series, at least one second sensing series, and at least one third sensing series. The substrate has at least one first sensing region and at least one second sensing region alternatively arranged in a first direction. Each first sensing series extends along the first direction and includes at least one first-first sensing portion located in the first sensing region and at least one second-first sensing portion located in the second sensing region. A pattern or material of the second-first sensing portion is different from that of the first-first sensing portions. Each second sensing series extends along a second direction intersecting with the first direction and is intersected with the first-first sensing portion. Each third sensing series extends in the second direction and is intersected with the second-first sensing portion.
