Abstract
A display input device according to one aspect of the present disclosure includes display portion, piezoelectric element, drive portion, and detection portion. The display portion includes touch panel that detects touched position on display surface. The piezoelectric element is provided on touch panel and vibrates touch panel. In response to touch panel being touched, drive portion applies a voltage to piezoelectric element to vibrate piezoelectric element. The detection portion detects the voltage value of a voltage generated in piezoelectric element by a pressure being applied to piezoelectric element when touch panel is touched. The smaller the voltage value detected by detection portion is, the larger the voltage applied to piezoelectric element by drive portion for vibrating piezoelectric element is. The larger the voltage value detected by detection portion is, the smaller the voltage applied to piezoelectric element by drive portion for vibrating piezoelectric element is.
