Abstract
A sensing device includes a plurality of sensing electrodes arranged in a row direction and a column direction, a sensing circuit including a plurality of read-out circuits respectively connected to the plurality of sensing electrodes and a control circuit for controlling the plurality of read-out circuits, and an arithmetic circuit that arithmetically is configured to process a sensing signal output from the sensing circuit. The plurality of sensing circuits and the plurality of read-out circuits are connected one-to-one via wiring. The sensing circuit is configured to store a driving table storing multiple sampling frequencies different from each other. The control circuit is configured to read out the multiple sampling frequencies, drives simultaneously the plurality of read-out circuits at the multiple sampling frequencies, and output a plurality of output signals to the arithmetic circuit. The arithmetic circuit is configured to calculate the amount of noise using the multiple sampling frequencies.
