The utility model discloses a touch panel circuit with an electric energy metering function. The touch panel circuit comprises a non-isolated alternating current-direct current conversion module, an electric energy metering module, an isolated power supply and communication module, a control module and a touch module, the non-isolated AC-DC conversion module is electrically connected with the electric energy metering module and the isolated power supply and communication module. The isolation power supply and communication module is electrically connected with the electric energy metering module and the control module. The control module is electrically connected with the touch module; the non-isolated alternating current-to-direct current module outputs a non-isolated direct current power supply; the electric energy metering module takes a non-isolated direct-current power supply as power supply input, detects a voltage signal and a current signal of a load, calculates electric energy and provides electric e
