Abstract
The touch control system with multi-touch detection functions includes a touch panel, a first transceiver, a second transceiver, and a processor. The first transceiver scans N first sensing lines along a first axis of a touch panel, and detects at least one first sensing line touched by at least one object according to the scanning result. The first transceiver inputs at least one high frequency signal to the at least one first sensing line touched by the at least one object, and the second transceiver inputs M low frequency signals to M second sensing lines along a second axis of the touch panel. The processor receives and detects M feedback signals of the M second sensing lines along the second axis, and determines a position of at least one touch point according to the M feedback signals.
