Abstract
The detecting device includes a detecting unit including a first electrode and a second electrode, the first electrode and the second electrode being used as a first capacitor. The detecting device includes a drive unit configured to apply a first drive signal to the first drive terminal such that the first drive signal is alternately inverted between a first period and a second period. The detecting device includes a converting unit configured to convert a charge charged at the signal terminal into a voltage and includes a difference processing unit configured to obtain a difference between the first output voltage and the second output voltage.
