More Information
Summary:The present disclosure relates to a touch device and a driving method thereof. The display device includes a plurality of driving electrodes, a plurality of sensing electrodes, a driving circuit, and a sensing circuit. The sensing electrodes and the driving electrodes cooperatively define a plurality of sensing points. The driving circuit connects with the driving electrodes and provides a plurality of driving signals to the driving electrodes. The driving circuit circularly drives the driving electrodes. The sensing circuit connects with the sensing electrodes, receives a plurality of sensing signals from the sensing electrodes, and determines one or more positions of the sensing points based on the sensing signals. During a driving circulation, a duration of each driving signals applied to the driving electrodes by the driving circuit is identical, and at least two driving signals are partially superposed.
