Problems solved by technology

It can be seen that the total thickness of this ITO smart film generally reaches more than 250 μm, and after being attached to the surface of the mobile phone, it will be much higher than the surface of the mobile phone, and it has no special advantages compared with the glass structure in terms of aesthetics and feel;
[0007] 2. The transparent conductive film is made of indium tin oxide (ITO). Because it is fragile during cutting / punching, the wiring of the edge lead (conductive area) must be kept away from the edge, which will block the touch icon or touch point on the display screen. Phenomenon, resulting in local insensitivity or malfunction of the mobile phone during normal touch operation, seriously affecting the actual operating experience

Abstract

The invention discloses an intelligent screen pasting film. The intelligent screen pasting film comprises a PET film, the PET film is adopted as the surface of the intelligent mobile phone pasting film, one face of the PET film is provided with a functional coating, the other face of the PET film is provided with a graphene conductive film, and the graphene conductive film is attached to an AB glue layer. According to the AB glue layer, different glue layers are arranged on the two faces of the PET film correspondingly, the face A is the face where the PET is attached to a graphene layer and is provided with an acrylate bonding agent, and the face B is the face attached to a screen and is provided with a silica gel system light bonding agent. Compared with a traditional ITO three-layer structure intelligent protection film, the intelligent pasting film has better advantages in thickness, bending resistance and other aspects, the intelligent pasting film can be repeatedly pasted on a smart phone many times, the ultrathin functional protection film is obtained, and the problems that the overall thickness of the protection film is large, and a conduction area shields a touch control icon or a touch control point of a display screen view window area are solved.

Description

technical field [0001] The invention relates to a screen intelligent sticking film and a preparation method thereof, belonging to the research field of optical-grade protective films. Background technique [0002] In recent years, the technology and market of portable electronic products have developed rapidly, especially the development of smart phones. Applying a protective film to the surface of a smartphone is very common among smartphone consumers. Smartphone protective film has multiple functions, such as anti-screen burst, anti-fingerprint, anti-scratch, anti-glare, anti-blue light and many other functions. [0003] The iphone series mobile phones developed by Apple Inc. in the United States are currently one of the most popular smart phones among consumers. They adopt the IOS operating system independently developed by Apple Inc. Another operating system that keeps pace with the IOS operating system is the Android system developed by Google in the United States, wh...
