  • Publication number: 20170068353
    Abstract: The present invention provides a touch substrate, a manufacturing method thereof, and a display device. In the touch substrate of the present invention, first leads of a first-layer structure are connected with first patterns in a second-layer structure via first via holes, second leads of the first-layer structure are connected with second patterns in the second-layer structure via second via holes, and the first patterns and the second patterns produce mutual capacitance. Each first pattern comprises a plurality of branches radiating from the center to the circumference, each second pattern surrounds one first pattern in a mutually separated manner, and when the touch substrate is used for flexible display, the second patterns can cover the whole bent surface, so that when a user touches any place of the touch substrate, the touch substrate can quickly respond and blind spots cannot be formed.

  • Publication number: 20160364063
    Abstract: 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.
