Abstract
A driving method for a haptic feedback substrate includes obtaining a haptic feedback signal required by a user; and driving the haptic feedback substrate to vibrate according to the haptic feedback signal. A first AC signal is loaded to a piezoelectric vibration unit of the haptic feedback substrate. A frequency of the first AC signal is greater than a frequency of the haptic feedback signal. The haptic feedback substrate is configured to resonate under an action of the first AC signal. At a stable vibration stage, the haptic feedback signal is loaded to the piezoelectric vibration unit. At a terminal vibration stage, a second AC signal is loaded to the piezoelectric vibration unit. A frequency of the second AC signal is a non-resonant frequency of the haptic feedback substrate. The frequency of the second AC signal is greater than the frequency of the haptic feedback signal.
