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

摘要

A pressure-sensitive display screen touch-control unit, a touch screen and a manufacturing method thereof. The touch-control unit mainly comprises a driving electrode, a lower electrode, and a dielectric layer sandwiched between the driving electrode and the lower electrode. When a pressure is applied between the driving electrode and the lower electrode, a tunnel current IT is formed, and a voltage VT exists between the driving electrode and the lower electrode. With the touch-control unit, an external pressure may be converted into a current signal to make pressure an information input mode; and the touch-control unit is combined with the existing capacitive touch screen or the resistive touch screen, such that the touch-control unit may be compatible with the existing multi-point touch function, and may also sense change in pressure sensitively. Functions of the existing touch screens may be enhanced to rich operations and applications of touch screens.
