Ultrathin composite transparent conductive film and preparation method thereof

Abstract

The invention discloses an ultrathin composite transparent conductive film, which comprises a transparent substrate, wherein a first UV adhesive layer, a second UV adhesive layer and a third UV adhesive layer are arranged on one surface of the transparent substrate, the first UV adhesive layer is subjected to graphical impressing, curing and conductive material filling to form a latticed groove ofa first conductive layer and a lead wire groove of a first lead wire area, the depth of the latticed groove of the first conductive layer and the depth of the lead wire groove of the first lead wirearea are smaller than the thickness of the first UV adhesive layer, the second UV adhesive layer is arranged on the surface of the first UV adhesive layer, the second UV adhesive layer is used as a reinforced insulation support layer, the third UV adhesive layer is subjected to graphical imprinting, curing and conductive material filling to form a latticed groove of a second conductive layer and alead wire groove of a second lead wire area, and the depth of the latticed groove of the second conductive layer and the depth of the lead wire groove of the second lead wire area are not larger thanthe thickness of the third UV adhesive layer. The conductive film is simple in structure, simplified in process, stable in process and wide in application scene.

Description

technical field [0001] The invention relates to the technical field of conductive films, in particular to an ultra-thin composite transparent conductive film, a preparation method thereof, and products using the conductive film. Background technique [0002] Transparent conductive film is a film with good electrical conductivity and high light transmittance in the visible light band. It has been widely used in flat panel displays, photovoltaic devices, touch panels and electromagnetic shielding, and has a broad market space. Due to the various disadvantages of ITO, flexible, low-resistance metal grid-like transparent conductive films are playing an increasingly important role. [0003] The transparent conductive film in the prior art refers to "a thin film capable of conducting electricity, which can realize some specific electronic functions". Generally, a conductive layer is made on a transparent substrate, which usually includes a transparent substrate layer, and related ...

AI Technical Summary

Problems solved by technology

The single transparent conductive film produced in this production step does not consider the material deformation caused by the process, which leads to the problem of dimensional deformation of the capacitor electrode pattern

In the actual production of mass products, there are problems such as low yield and high cost

[0006] The production of conductive films in the prior art usually has the following technical problems. The production process is complicated, and the product quality cannot be stably controlled, and the yield rate is low. Restricted, it does not conform to the current trend of ultra-light and ultra-thin development of touch screens, and the cost is high; future electronic equipment will gradually develop in the direction of curved surface design and flexible screen design, but it is made of two pieces of transparent conductive films that are bonded to each other. The finished touch module has poor bending resistance

[0007] For this reason, the present invention proposes a functional transparent conductive film of a multilayer composite structure and a manufacturing method, which solves the defects of existing product structures and manufacturing methods
