TOUCH PANEL DEVICE, INFORMATION PROCESSING DEVICE, TOUCH DETECTION METHOD AND STORAGE MEDIUM

WIPO Patent Application WO/2013/129304

A1

A touch panel device (10) is provided with: a touch panel (12) having first electrodes (X1) to (X8) and second electrodes (Y1) to (Y4) facing each other and having a touch surface partitioned into a plurality of areas; scan units (141) and (161) for applying a scan voltage to the first electrodes (X1) to (X8); and control units (142) and (162) for detecting and outputting the position touched on the touch surface inside the areas on the basis of change in the voltage of the second electrodes (Y1) to (Y4), controlling the scan units (141) and (161) so that a scan voltage is applied at a first frequency to the first electrodes (X1) to (X8) within the areas in the case that the position within the areas is not detected for a prescribed time or longer, and controlling the scan units (141) to (146) so that scan voltage is applied at a second frequency that is higher than the first frequency to the first electrodes (X1) to (X8) within the areas in the case that the position within the areas has been detected.
