The bottom wall has first and second regions in which the first region is more easily displaced in response to the pressing operation than the second region. A press sensor is disposed on the bottom wall in the cavity and extends across portions of the first and second regions.

Abstract: A pressing sensor is provided that generates an output voltage of a first polarity by deforming with an operation plate when a part of a user's body touches the operation plate, and generates the output voltage of a second polarity by deforming with the operation plate when the part of the user's body is moved away from the operation plate. Moreover, a calculation unit calculates an electrical parameter integral value by time-integrating an electrical parameter that changes with the output voltage generated by the pressing sensor. The electrical parameter has a third polarity when the output voltage has the first polarity and has a fourth polarity when the output voltage has the second polarity. The calculation unit calculates a subtraction electrical parameter integral value obtained by subtracting a predetermined value having the third polarity per unit time from the electrical parameter integral value.

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 (Vth1) 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 (Vth2) 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.
