    摘要: A touch panel includes a conductive film having anisotropic impedance, a plurality of first electrodes, and a plurality of second electrodes. In a method for detecting a touch spot, a plurality of actual detecting signals are obtained by the first electrodes and the second electrodes, thereby determining two first electrodes and two second electrodes closest to the touch spot. The conductive film between the two first electrodes and two second electrodes is defined as a corrective area. An ideal resistance of the corrective area is set. An arbitrary electrode from the two first electrodes and two second electrodes is defined as electrode i. The actual detecting signal Si obtained by the electrode i is corrected according to a ratio of the ideal resistance to an actual resistance of the untouched corrective area.

    摘要: A touch panel and a differential detection method thereof are disclosed. A controller provides a driving signal to the i-th scan electrode. During providing the driving signal to the i-th scan electrode, the controller senses the feature difference value between two neighboring sensing electrodes within the plural sensing electrodes, and senses the feature difference value ΔCi between the k-th sensing electrode within the sensing electrodes and a reference feature value, in which the feature difference values between the j-th sensing electrode and the (j+1)-th sensing electrode is represented by ΔC(i,j). The controller set the feature value of a base sensing point within a plurality of sensing points of the touch panel as a base feature value, and use the base feature value, the feature difference values ΔCi and the feature difference values ΔC(i,j) to calculate the feature values of the sensing points.
