description The present disclosure provides a touch sensing circuit comprising an analog signal processing circuit configured to receive a plurality of sensing signals having different frequencies from touch electrodes; and a digital signal processing circuit configured to receive output data of the analog signal processing circuit and perform a discrete Fourier transform. In addition, the present disclosure provides a touch sensing circuit comprising the digital signal processing circuit of the touch sensing circuit that separates the plurality of sensing signals through the discrete Fourier transform and allowing a simultaneous sensing of a finger touch and a stylus pen touch.
