Abstract

The invention provides a touch sensor, a touch display device and a preparation method of the touch sensor. With the invention, when the touch sensor is stretched for use, the surface resistance of aconducting layer of the touch sensor and the channel impedance of the touch sensor do not increase, so that touch signals are attenuated quickly, and the use stability of the touch sensor is not affected. The touch panel comprises: a conductive layer configured to convert a touch signal into an electrical signal; a wiring layer is arranged at the edge of the conductive layer and is configured tobe electrically connected with an external circuit; wherein the wiring layer is electrically connected with the wire layer, and the wiring layer and the wire layer are made of materials subjected topre-stretching treatment.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch sensor, a touch display device and a method for preparing the touch sensor. Background technique [0002] At present, with the advancement of technology, organic light-emitting touch display devices with stretchable structures are widely used in electronic equipment in daily work and life. However, when the stretchable touch sensors currently used are stretched, due to The conductive layer on the elastic substrate is stretched, resulting in a significant increase in the surface resistance of the conductive layer, and an increase in the channel impedance of the touch sensor, which accelerates the attenuation of the touch signal, thus affecting the use stability of the touch sensor. Therefore, how to reduce the change in surface resistance of the conductive layer during stretching becomes a key issue to improve the stability of the touch sensor. Contents of the i...
