Abstract

The invention relates to the technical field of touch panels, in particular to a high-applicability touch sensor for a touch panel. The high-applicability touch sensor includes a flexible backsheet layer, the flexible bottom sheet layer is fixedly connected with the first insulating layer; a first patterned conductive layer and a circuit layer are arranged above the first insulating layer; the first patterned conductive layer is electrically connected with the circuit layer; the first patterned conductive layer is fixedly connected with the transparent organic film layer, the transparent organic film layer is fixedly connected with the second patterned conductive layer, the first patterned conductive layer and the second patterned conductive layer both adopt a negative poisson ratio metalgrid design, the second patterned conductive layer is fixedly connected with the second insulating layer, and the second insulating layer is fixedly connected with the protective film layer. The high-applicability touch sensor has the beneficial effects that the negative poisson ratio metal grid design is adopted, the bending resistance is high, and the manufactured touch panel has flexibility andcan be suitable for different use conditions.

Description

technical field [0001] The invention relates to the technical field of touch panels, in particular to a touch sensor for touch panels with strong applicability. Background technique [0002] The application of touch sensing technology is becoming more and more popular. Traditionally, the sensing electrodes on the touch sensor for sensing the touch position are made of indium tin oxide material. However, due to technical problems such as excessive resistance, high price, and the need for multiple processes, indium tin oxide encounters bottlenecks in large-scale touch applications. Therefore, a technique using metal grids as sensing electrodes has been developed. [0003] In the sensing electrode structure of the metal grid, a fine metal is used as a wire and formed into a grid to replace the traditional sensing electrode formed of indium tin oxide. Since metal materials are used as wires to transmit sensing signals, they have better conductivity than ITO materials, and are ...
