TOUCH SCREEN

摘要

A touch screen contains a capacitive sensing layer, a first controller for detecting a touching position, a piezoelectric sensing layer, a second controller for detecting a touching pressure, and a main controller. The touch screen also comprises a window area and a non-window area, the capacitive sensing layer is arranged in the window area, the piezoelectric sensing layer is arranged in the non-window area. The first controller connects with the capacitive sensing layer, the second controller couples with the piezoelectric sensing layer, and the main controller is in connection with the first controller and the second controller. The first controller transmits a touching signal of the capacitive sensing layer to the main controller, and the second controller transmits a pressing signal of the piezoelectric sensing layer to the main controller, such that the main controller acquires the touching position and the pressure value on the touch screen.
