摘要： The present invention relates to a sensing circuit with signal compensation, which comprises a first sensing element, a second sensing element and a differential amplifying circuit, the differential amplifying circuit generates an output signal through a differential compensation according to a common mode voltage, a first sensing signal and a second sensing signal. Hereby, reducing the noise of the sensing circuit is achieved, and the interference of the display driving signal may be effectively improved.
