Abstract: The present invention provides a touch module, which comprises a touch panel, an analog front end circuit, and a microcontroller circuit. The touch panel generates a plurality of sensing signals. The analog front end circuit is coupled to the touch panel, generates a state signal, and generates a plurality of touch detecting signals according to the plurality of sensing signals. The microcontroller circuit is coupled to the analog front end circuit, generates one or more touch location signal according to the plurality of touch detecting signals, and enters the next switching state according to the state signal when the switching state is changed.
