Panel structure
Panel structure includes a substrate, a piezoelectric material layer and a thin film transistor. The piezoelectric material layer is disposed under the substrate, in which the piezoelectric material layer is configured to generate human recognizable sound waves by vibrating at a human audible frequency in a first time interval, and the piezoelectric material layer is configured to generate ultrasonic waves by vibrating at an ultrasonic frequency in a second time interval. The piezoelectric material layer is used for recognizing human fingerprints when it vibrates at the ultrasonic frequency. The thin film transistor is positioned under and electrically connected to the piezoelectric material layer.
