Problems solved by technology

However, after the blanket is printed for a long time, it will absorb the solvent in the ink and swell, resulting in a decrease in the stability of the transferred grid ink, which will affect the formation of the subsequent metal layer and reduce the conductivity of the conductive film.

Embodiment Construction

[0024] see Figure 1~3 , a method for preparing a conductive film 100, comprising the steps of:

[0025] A base layer 11 is provided, and the material of the base layer 11 is a transparent flexible material. The transparent flexible material can be polyethylene terephthalate, polyethylene naphthalate, polyolefins (such as polyethylene, polypropylene, polystyrene or ethylene-vinyl acetate copolymer), vinyl series resins (such as polyvinyl chloride, polyvinylidene chloride), polyetheretherketone, polysulfone, polyethersulfone, polycarbonate, polyamide, polyimide, acrylic, or trivinyl cellulose.

[0026] see further figure 1 , provide a transparent insulating adhesive, and form a transparent insulating adhesive layer 12 on a surface of the base layer 11 to obtain the substrate 10 . The method of forming the transparent insulating adhesive layer 12 may be various conventional methods in the field such as coating and spraying. The thickness range of the transparent insulating a...

Abstract

The invention relates to a conducting film. The conducting film comprises a basic layer, a latticed ink layer and a latticed metal layer, wherein the ink layer is combined to the surface of the basic layer, the metal layer is combined to the surface of the ink layer, and the conducting film also comprises a transparent insulating adhesive layer which is arranged between the basic layer and the ink layer, and the ink layer is combined to the surface of the transparent insulating adhesive layer. The adhesive layer is used for substituting the traditionally used rubber cloth to bring out the ink in a groove and transfer the ink to the basic layer, thus a midbody needed by the preparation of the conducting film can be obtained through the printing in one step, and the worsening of the stability of the latticed ink layer caused by the swelling of the conducting film in the prior art that auxiliary articles adsorb solvent in the ink after the conducting film is printed for a long time can be avoided, and the prepared conducting film is good in conductivity and electromagnetic shielding effect. In addition, the invention also provides a preparation method of the conducting film, a touch screen utilizing the transparent conducting film and an electronic device utilizing the touch screen.

Description

technical field [0001] The invention relates to a conductive film and a preparation method thereof, a touch screen and an electronic device using the conductive film. Background technique [0002] In recent years, transparent conductive films have been widely used in touch screens, flat panel displays, photovoltaic devices, electromagnetic shielding and other fields, especially in the field of capacitive touch screens, which has grown rapidly. A touch screen is a sensing device that can receive input signals such as touch. The development of touch screen technology has attracted widespread attention at home and abroad, and it has become a high-tech industry that has sprung up in the optoelectronic industry. [0003] The emergence of metal grids is a better choice for medium and large size touch screens. In the prior art, a blanket is usually used as a medium to transfer the ink to the printed object in the preparation of the metal grid, and the blanket is the coating of th...
