Abstract
A detecting device includes a plurality of first electrodes extending in a first direction and a plurality of second electrodes extending in a second direction intersecting the first direction, the first electrodes and the second electrodes being disposed facing each other with an insulating layer interposed therebetween, a first electrode selection circuit configured to change a combination of a plurality of selected first electrodes for each of a plurality of periods obtained by dividing one frame period and supply a drive signal to the selected first electrodes, and a detection circuit configured to detect capacitance generated between the first electrodes and the second electrodes due to the drive signal. The first electrode selection circuit changes a frequency of the drive signal for each of the periods.
