Abstract
A pseudo-piezoelectric d33 vibration device includes transistors and receivers electrically connected to the transistors. Each transistor controls a corresponding one of the receivers to receive a second vibration wave, generated after an object reflects a first vibration wave, and to generate a sensing signal. Each receiver has a first electrode, a second electrode and a nano-gap, which is created between the first and second electrodes after a semiconductor-metal compound is formed. A display integrating the pseudo-piezoelectric d33 vibration device is also provided.
