Patent ID: 8749519

Claim:
A touch panel device comprising: a touch panel including, in an input area, a capacitance detecting electrode and a resistance detecting electrode formed in a layer below the capacitance detecting electrode; and a control circuit using detection signals detected by the capacitance detecting electrode or the resistance detecting electrode to calculate a contact position on an input surface of the input area, wherein the capacitance detecting electrode includes horizontal capacitance detecting electrodes arranged in parallel in the vertical direction of the input area and each having a plurality of first planar portions arranged in parallel in the horizontal direction and a straight-line-shaped first coupling portion coupling the first planar portions, and vertical capacitance detecting electrodes disposed in a layer different from that of the horizontal capacitance detecting electrode, arranged in parallel in the horizontal direction, and each having, in a view of the input surface, a plurality of second planar portions arranged in parallel in the vertical direction at positions not overlapping the first planar portions and a straight-line-shaped second coupling portion coupling the second planar portions, the resistance detecting electrode includes resistance detecting linear electrodes having, in the view of the input surface, a lattice shape in which each of the resistance detecting linear electrodes passes between the first planar portions and the second planar portions in the input area, and the control circuit includes a contact position information generating section which uses the detection signals to calculate one or more contact positions and generates information of large/small pressing force at the calculated contact position.
