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.

摘要： A method and a driving apparatus for identifying a sensing value of a touch panel are provided. The method includes sensing a plurality of electrodes of the touch panel to obtain raw data and baseline data of each electrode, wherein an electrode Si denotes an ith electrode of the electrodes in the touch panel. A sensing value of the electrode Si is calculated in accordance with the raw data and the baseline data of the electrode Si. When sensing values of all electrodes Si are smaller than a threshold value, the baseline data of the electrode Si is updated in accordance with the raw data of the electrode Si. When a sensing value of any one electrode Si of the electrodes is larger than the threshold value, the baseline data of the electrodes is suspended from being updated.

摘要： A multi-touch detecting method is adapted for detecting locations of touched points on a touch panel including first and second conductive films, and includes following steps. First measuring points of the first conductive film distributed along X-axis of a Cartesian plane are scanned, and x-components are determined accordingly. Second measuring points of the second conductive film distributed along Y-axis of the Cartesian plane are scanned, and y-components are determined accordingly. A first voltage is applied to the first conductive film, and A second voltage is applied to at least one of the second measuring points with the location on the Y-axis adjacent to or overlapping one of the y-components. Voltages at the first measuring points with the locations on the X-axis adjacent to or overlapping the x-components are measured sequentially and one of the y-components and one of the x-components are outputted.
