Abstract
The present invention relates to a capacitive touch panel. In one embodiment, the capacitive touch panel includes a plurality of driving electrodes and a plurality of sensing electrodes spatially arranged in a matrix, and a driver electrically coupled to the touch sensor matrix and configured to generate a driving signal to synchronically drive one or more driving electrodes and the sensing electrodes, such that at least one sensing electrode is not driven by the driving signal. The remaining driving electrodes are grounded. The not-driven sensing electrodes sense and transmit a sensing signal of a touch.
