The voltage signal and the timing signal are transmitted to an external controller, and the external controller determines the X corresponding to the contact point by analyzing the resistance line 381 of the detected voltage to be pulled in all the electric lines 3H. The axial seat: the method of determining the 檫 coordinate is the same as the method of the first embodiment; the if, ie, the outer if controller determines the contact point Y by comparing the timing of the contact point gate line 312 with the timing of the gate control circuit. Axial coordinates. The precise position of the contact point is finally determined by the above method and displayed on the display panel. [0025] In summary, the present invention has indeed met the requirements of the invention patent, and the patent application is filed according to law. However, the above-mentioned embodiments are merely preferred embodiments of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and those skilled in the art will be able to make equivalent modifications or variations in accordance with the spirit of the present invention. It should be covered by the following patent application. 095143783 Form No. A0101 Page 10 of 25 0993445157-0 1345668 Modified on December 14, 099.
