SENSING ELECTRODES AND SENSING METHOD THEREOF |
摘要 |
A plurality of dummy lines are arranged between a plurality of sensing electrode unit pairs to compensate a capacitance sensing value imbalance caused by two sensing electrodes. Further, a coordinate compensation value is calculated according to a layout of electrodes and wires to alleviate or reduce a ripple effect of sensed position errors. As such, sensing accuracy of a touch sensing apparatus is improved. |
