Abstract
A display device includes a housing, an operation plate, an electrostatic sensor, a piezoelectric sensor, a controller, a storage unit, a display, and a communication unit. When an output voltage of the piezoelectric sensor indicates a first voltage value (V) or larger, the controller determines that the piezoelectric sensor has detected a change in a first pressing force and performs first processing. When an output voltage of the piezoelectric sensor indicates a second voltage value (V) or larger, the controller determines that the piezoelectric sensor has detected a change in a second pressing force. When the piezoelectric sensor detects the change in the second pressing force and the electrostatic sensor continuously detects a touch during a period from the detection of the first pressing force to the detection of the second pressing force, the controller executes second processing.
