发明名称 Touch panel device
摘要 A touch panel device comprises a touch panel including 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. The capacitance detecting electrode includes horizontal capacitance detecting electrodes and vertical capacitance detecting electrodes. A control circuit includes a contact position information generating section which uses detection signals to calculate one or more contact positions and generates information of large/small pressing force at the calculated contact position. With this configuration, it is possible to generate information of large/small pressing force at a contact position, and even when an input surface is contacted simultaneously at plural points, each of the contact positions can be calculated.
