Abstract

A vibration type touch-sensing panel includes a substrate, a plurality of vibration units, and a control module, wherein the vibration units are disposed on the substrate to form a matrix. Each one of the vibration units includes a first electrode layer, a second electrode layer, and an electret layer, wherein the first electrode layer is disposed on the substrate. The electret layer is disposed between the first electrode layer and the second electrode layer and located on one of the first electrode layer and the second electrode layer. The control module provides a driving voltage between the first electrode layer and the second electrode layer so that the electret layer and one of the first electrode layer and the second electrode layer generate a relative vibration.
