Preparation method of reelable touch panel

Abstract

The invention relates to a preparation method of a reelable touch panel. The method includes the following steps of forming a nano-silver wire electric conduction electrode layer on a base material, coating the nano-silver wire electric conduction electrode layer with photoresist according to a specific pattern, leaving electric conduction electrode layer circuits needing to be reserved and removing the non-required part of the electric conduction electrode layer through etching after exposure, removing the photoresist on the electric conduction electrode layer circuits, and attaching explosion-proof films to the two sides of the double-layer structure formed by the base material and the nano-silver wire electric conduction electrode layer respectively. The metal fine circuit manufacturing process is adopted for the method, the nano-silver wire electric conduction electrode layer is coated with the photoresist according to the specific pattern, and the electric conduction electrode layer circuits needing to be reserved is left and the non-required part of the electric conduction electrode layer is removed through etching after exposure; superfine metal circuits are obtained, the problem of smooth transition of circuit falling position differences is mainly solved, broken circuits caused after being bent are avoided, and therefore reelability of the touch panel is achieved.

Description

technical field [0001] The invention relates to a production process of electronic components, in particular to a preparation method of a windable touch panel. Background technique [0002] As Samsung and Sharp's research on flexible screens matures, Corning also timely launched its own bendable glass WillowGlass, which also hints at an inevitable trend in future display technology. WillowGlass is only 0.1 mm thick, very flexible, and has a layer of laminated plastic on the outside, so people can easily bend the glass. The target of this technology is smart phones, and I believe that we will soon use smart phones with flexible screens in the near future. [0003] Smartphones with flexible screens must first solve the part of the driving layer material and replace ITO material technology requirements, not only for low price and thinner considerations, but also for the emergence of some flexible products, including small-sized wearable glasses, smart phones, etc. Sports equi...
