[0015] The present invention will be further described below in conjunction with the drawings and embodiments.
[0016] The method for detecting a touch device according to the present invention firstly involves the structure of a capacitive touch screen. reference figure 1 As shown, the capacitive touch screen 10 is mainly composed of a driving line 20 and a sensing line 30 as an electrode matrix. The driving line 20 and the sensing line 30 are placed crosswise, a mutual inductance capacitor 50 is formed at the intersection, and the driving line 20 and the sensing line 30 The electrodes respectively constitute the two poles of the mutual inductance capacitor 50. When a finger touches the capacitive screen, a coupling capacitance is generated with the two electrodes near the touch point 70, causing a change in the capacitance between the two electrodes. When detecting, the driving line 20 passes through the driving circuit Signals are sent out in sequence at 40 minutes. When one ...
