Abstract
The present disclosure provides a driving device for driving a sensing device having a plurality of driving electrodes and a plurality of sensing electrodes. The driving device includes a signal processing circuit and a readout circuit. The signal processing circuit is electrically connected to the plurality of driving electrodes of the sensing device. The signal processing circuit is configured to generate a plurality of driving signal to drive the sensing device. The signal processing circuit selects a plurality of Walsh codes from a plurality of rows or columns of a Walsh matrix to serve as a plurality of driving signals. The readout circuit readouts the sensing device to generate a plurality of sensing signals and provides the plurality of sensing signals to the signal processing circuit, so that the signal processing circuit demodulates the plurality of sensing signals. In addition, a driving method is also provided.
