Abstract

A piezoelectric sensor includes a piezoelectric device and a touch bump. When an external force is applied on the piezoelectric sensor, the piezoelectric device has a higher deformation and a higher electrical signal due to contact with the press surface of touch bump. Accordingly, the piezoelectric device has better sensitivity. The piezoelectric sensor of the present invention may be integrated into a liquid crystal display panel to reduce the complexity of sensor signal processing circuit.
