Method and system for measuring position on surface capacitance touch panel using a flying capacitor |
摘要 |
A touch panel having a substantially even coating of a conductive material on a non-conductive substrate and then covering the conductive material with a dielectric material, wherein a novel current measuring circuit reduces the effect of stray capacitance on the accuracy of a current measurement so that the relative X and Y position of an object on the touch panel can be determined using simple ratio equations. |
