Abstract:
1. A touch control system with multi-touch detection functions, the touch control system comprising: a touch panel for being touched by at least one object, a first axis direction of the touch panel having N first sensing lines and a second axis direction of the touch panel having M second sensing lines; a first transceiver coupled to the N first sensing lines for scanning the N first sensing lines in the first axis direction of the touch panel; a second transceiver coupled to the M second sensing lines for scanning the M second sensing lines in the second axis direction of the touch panel; and a processor coupled to the first transceiver and the second transceiver for detecting at least one first sensing line touched by at least one object according to a scanning result of the first transceiver, controlling the first transceiver to input at least one high frequency signal to the at least one first sensing line touched by the at least one object and controlling the second transceiver to input M low frequency signals to the M second sensing lines in the second axis of the touch panel, detecting M feedback signals of the M second sensing lines received by the second transceiver, and determining a position of at least one touch point according to the M feedback signals.
