Abstract
A cascade touch control system includes a touch panel composed of a plurality of transmit lines and a plurality of receive lines; and a plurality of drivers controlling corresponding blocks of the touch panel, each block being divided into matrices each including same number of transmit lines and receive lines. Multi-tone touch control is performed on matrices of the blocks. For each matrix of each block, transmit signals are transmitted in each time interval associated with a corresponding receive line, of which one transmit signal has a phase opposite to other transmit signals, and different transmit signals with the opposite phase correspond to different time intervals.
