Abstract
A touch panel is disclosed. The panel has a substrate having a touch region with a plurality of touch areas, a touch position detection apparatus, at least one pressure sensor group and a processor. The at least one pressure sensor group is disposed on the substrate. The pressure sensor group includes a first-type pressure sensor and a second-type pressure sensor. The first-type pressure sensor is located on a first side of the touch region and the second-type pressure sensor is located on a second side opposite to the first side of the touch region so that the first-type pressure sensor and the second-type pressure sensor of the same pressure sensor group are symmetric about the centerline of the touch panel. Each of the plurality of touch areas is associated with one of the at least one pressure sensor group.
