Input device and method for driving input device
30 Sep 19
An input device includes a voltage divider circuit that includes a resistive sensor whose resistance changes in accordance with a change in pressure of a pressing operation and at least one resistor device and that, upon receiving driving voltage, generates a divider voltage according to the resistance of the resistive sensor device, a first driving circuit that alternately supplies, to the voltage divider circuit at certain time intervals, a first driving voltage and a second driving voltage for generating different divider voltages, a capacitor whose charge changes in accordance with a change in the divider voltage, and a first charge detection circuit that detects an amount of change in the charge of the capacitor at a time when the driving voltage changes from the first driving voltage to the second driving voltage and when the driving voltage changes from the second driving voltage to the first driving voltage.
