PRESSURE-SENSITIVE DISPLAY TOUCH UNIT, TOUCH SCREEN, AND MANUFACTURING METHOD THEREOF

摘要

Disclosed are a pressure-sensitive display touch unit, a touch screen, and a manufacturing method thereof. The touch unit mainly comprises a drive electrode, a lower electrode, and a dielectric layer between the drive electrode and the lower electrode. When a pressure is applied between the drive electrode and the lower electrode, a tunnel current IT is formed, and a voltage VT exists between the drive electrode and the lower electrode. By using the touch unit of the present invention, an external pressure can be converted into a current signal, and the pressure becomes an information input manner. Further, by combining the touch unit of the present application with an existing capacitive touch screen or resistive touch screen, the touch unit not only can possess the existing multi-point touch function, but also can sensitively sense the change in pressure and enhance the function of the existing touch screen, providing more operational applications for the touch screen.
