Problems solved by technology

[0003] However, the basic structure of the existing touch sensor is the emitting layer, optical glue (Optically Clear Adhesive, OCA), receiving layer and cover glass, usually no feedback to the touch force, tactile feedback usually requires an additional tactile sensor (tactilesensor); This not only makes the overall manufacturing process of the device more complicated, but also unsatisfactory in terms of user experience, such as thickness, weight, light transmittance, and flexibility.
As we all know, the existing tactile sensor process requires more than a dozen steps. If the touch sensor is added, the overall thickness, light transmittance, flexibility, etc. will be further affected.

Abstract

The invention provides a touch sensor. The touch sensor comprises a substrate and a conductive thin film. The conductive thin film comprises an emitting layer, a receiving layer and a piezoelectric layer clamped between the emitting layer and the receiving layer. The conductive thin film is provided with a conductive pattern area and a conductive path area. The touch sensor has following beneficial effects: by arranging the piezoelectric layer clamped between the emitting layer and the receiving layer, the function of tactile feedback is integrated by the touch sensor; and the touch sensor is simple in structure technology and low in cost.

Description

technical field [0001] The invention relates to a touch sensor, in particular to a touch sensor with a simple structure and capable of feedbacking touch force, a preparation method thereof, and a display device with the touch sensor. Background technique [0002] With the development of mobile terminals, wearable devices, smart home appliances and other products, the demand for touch screens is increasing, and the requirements for touch sensors are also getting higher and higher. [0003] However, the basic structure of the existing touch sensor is the emitting layer, optical glue (Optically Clear Adhesive, OCA), receiving layer and cover glass, usually no feedback to the touch force, tactile feedback usually requires an additional tactile sensor (tactilesensor); This not only makes the overall manufacturing process of the device more complicated, but also unsatisfactory in terms of user experience, such as thickness, weight, light transmittance, and flexibility. As we all ...
