Method for detecting touch spot of touch panel
Abstract:
A method for detecting touch spots of a touch panel. In the detecting process, a pulse signal is input into each of a plurality of first driving-sensing electrodes, thereby simulating an R1nC curve for computing a coordinate of the touch spots, at a high impedance direction. The capacitance C is detected. A coordinate of the touch spot at a low impedance direction is obtained by calculating a ratio of the R1nC and the capacitance C to obtain the resistance R1n.
