Abstract
Embodiments of the present disclosure provide a haptics panel and a driving method thereof, and a haptics apparatus. The driving method includes: receiving a touch signal, and judging a touch position of a user on the haptics panel according to the touch signal; judging a characteristic frequency area to which the touch position belongs; determining characteristic mode displacement field distribution of the base substrate according to the characteristic frequency area to which the touch position belongs, wherein the characteristic mode displacement field distribution contains vibration displacement phase information at each position of the base substrate; dividing a plurality of piezoelectric devices arranged in an array contained in the haptics panel into at least one vibration area according to the vibration displacement phase information of the characteristic mode displacement field distribution; and loading voltage signals on at least part of the piezoelectric devices in the vibration area.
