TOUCH SCREEN, METHOD OF MANUFACTURING THE SAME AND DISPLAY PANEL

摘要

A touch screen includes a first electrode and a second electrode that are disposed oppositely, and a sensing layer disposed between the first electrode and the second electrode. The sensing layer is made of transparent material having piezoelectric effect. The touch screen can sense pressure by any object, and therefore cannot only sense a position of a contact, but also sense a magnitude and a change characteristic of acting force. Also, the touch screen according to the present disclosure directly converts the pressure applied by the object onto the touch screen into an electric signal, which reduces the power consumption greatly, and therefore reduces whole power consumption of the screen effectively.
