Problems solved by technology

However, "electroless plating" is recognized as a major hazard to the environment and consumes a lot of water and electricity
In addition, the mesh produced by this method needs to be pasted on the high-transmittance optical PET film with a cured adhesive containing organic volatiles, and the cured adhesive used for pasting will also be damaged due to the heat generated by the compone

Embodiment Construction

[0041] With the help of figure 1 An electromagnetic wave shielding film according to a preferred embodiment of the present invention will be described assuming that this embodiment is used to shield electromagnetic radiation from a display screen.

[0042] see figure 1 , the electromagnetic wave shielding film 1 is a composite layer structure, which mainly includes a film substrate 11, a metal mesh layer 12 located on one surface of the film substrate 11, an anti-oxidation layer 13 covering the surface of the metal mesh layer 12, and coated on the film substrate. The back adhesive film layer 14 on the other surface of the material 11 and the release paper 15 covering the surface of the back adhesive film layer 14 .

[0043] The film substrate 11 acts as the substrate of the electromagnetic wave shielding film to support the metal layer and the adhesive film layer. In addition, when used for a display screen of a display device, the film substrate 11 should have sufficient opt...

Abstract

The invention provides a kind of electromagnetic wave shielding films including: a film substrate with transparency on optical degree more than or equal to 87% and layers of metal net at least on one surface of the film substrate. The invention also provides a method including the following steps: first, a conductive layer is formed on the surface of film substrate by a method of physical vapor deposition, next, a metal layer is shaped on the conductive one by the technique of plating; then, metal reticular figure comes into being on such film substrate by laser-cutting technique. This invention can not only reduce the consumption of mental for electromagnetic shielding and avoid the use of solidifying glue between the layers of metal and film substrate, but also decreases the process steps to lower the cost of industrial production and increase productivity effectively.

Description

technical field [0001] The invention relates to electromagnetic radiation shielding technology, in particular to a high-transparency electromagnetic wave shielding film suitable for suppressing electromagnetic wave leakage of a display device and a manufacturing method thereof. Background technique [0002] It is currently known that various electronic products (such as cathode ray tube (CRT) displays, liquid crystal displays and plasma TVs, etc.) emit electromagnetic radiation of various wavelengths that are harmful to the human body through the casing or display screen during use. This radiation will cause harm to the human body, especially if it is close to the radiation source for a long time, it may cause various physiological diseases, such as increased degree of cell lesions, malignant diseases such as cancer, goiter, leukemia, dry eyes and Cervical disease etc. [0003] In order to prevent the electromagnetic radiation leakage of the display, the current practice is...
