Abstract: A touch panel device (11) includes a panel main body (21) including a plurality of first electrodes (X) extending parallel to one another and a plurality of second electrodes (Y) intersecting with the first electrodes (X), and a detection section (31). The detection section (31) includes a transmission section (33) for sequentially applying a driving signal to the first electrodes (X), and a current-voltage conversion section (35) configured to scan the second electrodes (Y) and convert a current flowing through the second electrode (Y) to a voltage signal, an AD conversion section (36) configured to sample the voltage signal and convert it to digital data, and a touch determination section (37) for determining a touch position from the converted digital data.

Abstract: A touch detection device includes a touch panel including a first electrode part arranged so as to extend in a first direction and a second electrode part arranged so as to extend in a second direction that is different from the first direction. The touch detection device also includes a pulse generating unit configured to output a pulse signal to the first electrode part, a resistance element arranged between an output terminal of the pulse generating unit and the first electrode part, and a touch detecting unit configured to detect whether the touch panel is touched or not based on a phase difference in a voltage signal of the second electrode part, which is generated in accordance with the pulse signal. The phase difference is based on whether the touch panel is touched or not.
