| 摘要 |
The present invention is related to a method for measuring pressure resistance of a touch panel. A reference resistor Rr is added to a measurement terminal which is coupled with a X-axis of a glass substrate of the touch panel. When users touch the touch panel, the touch point is where the glass substrate (X-axis) is electrically in contact with the outer layer (Y-axis). Because current I flowing through the reference resistor Rr and a touch point resistance Rt are equal; a voltage Va across the reference resistor Rr and a voltage Vb across the touch point resistance Rt are given, it is easy to calculate resistance of the touch point. The method of the present invention can be implemented by firmware so that it is fast, simple and accurate to calibrate the touch screen of the touch panel.
