Problems solved by technology

[0004] However, with Cu plating, because Cu metal is relatively active and easily oxidized in the atmosphere, after the traditional Cu plating process, it is necessary to print a layer of corrosion-resistant ink on the surface to protect the Cu layer, which makes the manufacturing process complicated and affects production. efficiency

Embodiment Construction

[0023] In the following, the flexible touch screen and its manufacturing method will be further described in detail mainly in conjunction with the accompanying drawings and specific embodiments.

[0024] like figure 1 As shown, a flexible touch screen 100 according to an embodiment includes a flexible substrate 110 , a transparent conductive film 120 and electrode leads 130 .

[0025] The material of the flexible substrate 110 in this embodiment is polyethylene terephthalate (PET).

[0026] The transparent conductive film 120 is disposed on the flexible substrate 110 . The transparent conductive film 120 of this embodiment is a transparent ITO (indium tin oxide) conductive film with a thickness of 20-30 nm. It can be understood that, in other implementation manners, the material of the transparent conductive film 120 may also be a metal-doped n-type semiconductor oxide such as aluminum zinc oxide (AZO), gallium zinc oxide (GZO) or indium zinc oxide (IZO).

Abstract

The invention relates to a flexible touch screen, and further relates to a preparation method for the flexible touch screen. The flexible touch screen comprises a flexible substrate, a transparent conductive film arranged on the flexible substrate and electrode leads electrically connected with the transparent conductive film, wherein each electrode lead comprises a copper lead arranged on the transparent conductive film and a copper-nickel alloy protecting film arranged on the copper lead. Copper-nickel alloy is good in oxidation resisting performance under atmosphere and can effectively prevent the copper lead from being oxidized or going bad, sputtering preparation of the copper lead and the copper-nickel alloy protecting film can be directly finished through one process without extra processes, and therefore production efficiency of flexible touch screens can be effectively improved, extra processes are prevented from damaging the transparent conductive film, and the percent of pass of the flexible touch screens is improved.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a flexible touch screen and a manufacturing method thereof. Background technique [0002] Traditional flexible touch screens mainly have two ITO wiring methods: one is the silver glue printing process; the other is to sputter a layer of metal on the flexible touch screen, such as copper (Cu), and then use the photolithography process to use the metal as ITO Wiring. [0003] Due to the inherent softness and heat resistance of flexible touch screens, there are certain limitations in the processing of sensors (sensors). In particular, the edge metal wiring of the sensor often adopts the Mo-Al-Mo process. The Mo-Al-Mo coating has relatively high temperature requirements, which exceeds the temperature tolerance limit of the thin film sensor. Therefore, Mo-Al-Mo is used on the edge of the thin film sensor. The process route is not very feasible, so the current use is to use Cu or Cu-cont...
