Abstract:
The present disclosure discloses a touch device and a method for driving the same which is capable of enabling the touch device to operate a higher display refresh rate when there is no touch. The touch device comprises a touch panel, a timing controller, a touch controller, a controller, and a sensor. The sensor is configured to detect whether there is an object contacting or approaching the touch panel, and to output a first indication signal if there is no object contacting or approaching the touch panel and a second indication signal if there is an object contacting or approaching the touch panel. The controller is configured to control the timing controller to output a first display scanning signal when the first indication signal is received and to control the timing controller to output a second display scanning signal when the second indication signal is received. The scanning frequency of the first display scanning signal is higher than that of the second display scanning signal.
