METHOD FOR DETECTING TOUCH SPOT OF TOUCH PANEL |
摘要 |
A method for detecting a touch spot of the touch panel includes the following steps. The electrode pairs are scanned along the impedance direction to obtain an electrical signal curve for determining a first coordinate. A number of first driving electrodes and a number of second driving electrodes near the first coordinate are selected. The selected first driving electrodes are scanned to obtain a first sensing signal. The selected second driving electrodes are scanned to obtain a second sensing signal. A second coordinate is determined according to the first and second sensing signals. Finally, the touch spot is determined according to the first and second coordinates.
