A touch control module includes a touch control unit operable so as to generate a contact signal in response to contact with an object, a computing unit coupled electrically to the touch control unit so as to receive the contact signal therefrom, and a transmission interface including a set of transmission lines coupled electrically to the computing unit. The computing unit is configured to generate different control signals, each of which is generated in accordance with a contact position of the object with the touch control unit. Each of the transmission lines is used to transmit a respective one of the control signals to a host unit for scrolling control of a graphical user interface display of the host unit.
