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.

A pseudo-piezoelectric d33 vibration device, comprising:
- transistors;
- and
- receivers electrically connected to the transistors, wherein each of the transistors 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, wherein each of the receivers has a first electrode, a second electrode and a nano-gap, which is created between the first electrode and the second electrode after a semiconductor-metal compound is formed.
A display, comprising:
- transistors;
- receivers electrically connected to the transistors, wherein each of the transistors 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, wherein each of the receivers has a first electrode, a second electrode and a nano-gap, which is created between the first electrode and the second electrode after a semiconductor-metal compound is formed;
- and
- display units each comprising at least one display control transistor and a display pixel electrically connected together, wherein the display control transistor controls enabling of the display pixel to display an optical signal and disabling of the display pixel not to display the optical signal so that data is displayed.
