The basic principle is as follows: and applying voltage to the driving electrode to detect the signal change of the sensing electrode. The drive electrodes determine the X-direction coordinates and the sense electrodes determine the Y-direction coordinates. During detection, the X-direction driving electrodes are scanned line by line, signals on each sensing electrode are read when each line of driving electrodes are scanned, and intersection points of each row and column can be scanned through one round of scanning, so that m × n signals are scanned in total.
