Positioning method for touch screen |
摘要 |
A positioning method for a touch screen including a conductive layer (241, 431, 441) having an anisotropic impedance and separated detecting electrodes disposed at a side of the conductive layer is provided. A first voltage is provided to the conductive layer. A second voltage is provided to the conductive layer when the touch screen is touched, wherein a touch point is defined as where the second voltage is applied. Voltages of the detecting electrodes (243, 433, 443) are sequentially measured. The relative extreme voltage and the voltage of the detecting electrode closest to the relative extreme voltage are selected. A coordinate of the touch point in the conductive layer is determined according to the relative extreme voltage and where the detecting electrode providing the voltage closest to the relative extreme voltage is. |
