Abstract: A touch panel is provided. The touch panel includes a substrate, a plurality of first sensing pads, a plurality of second sensing pads and an extension sensing pad. The substrate has a body portion and an extension portion. The first sensing pads are arranged abreast on the body portion of the substrate along a first direction. The second sensing pads are arranged abreast on the extension portion of the substrate along a second direction. The material of the first sensing pads is different from the material of the second sensing pads. The extension sensing pad is arranged on the extension portion of the substrate. Thus, the touch panel can be extended to side portions of an electronic device, so as to replace functions of physical buttons by using the touch panel on the side portions.

Abstract: A touch panel comprises a substrate, a touch sensing layer and a transparent cover. The touch sensing layer is disposed in the substrate. The transparent cover with different thickness is disposed on the touch sensing layer. The touch sensing layer has a plurality of sensing units. Each sensing unit corresponds to a thickness of the transparent cover. According to the thickness of the transparent cover, an area of corresponding sensing unit and a distance between corresponding sensing unit and its adjacent sensing unit are decided.
