Abstract:
In a location detection device, a capacitive touch panel is disposed on a surface of a display screen of a display device. The location detection device includes a touch panel that includes a plurality of transparent electrodes arranged in mutually intersecting directions; a location detection unit that detects a touch location of an instruction body by selecting parts of the plurality of transparent electrodes and measuring a change in capacitance between the parts; and, a low impedance setting unit that, at a point in time when the location detection unit selects the parts of the transparent electrodes, puts remaining transparent electrodes into a low impedance state.
