Problems solved by technology

[0007] 1. The plastic structure and part of the glass structure adopt a flat structure. Since it cannot fit tightly on the curved surface of the edge of the mobile phone, the edge of the film can be clearly seen on the edge of the mobile phone window. It is similar to the glass structure in terms of aesthetics and feel. There is no special advantage over both; and if the glass structure is made into curved glass, it is difficult to be functional
[0008] 2. Secondly, the functional realization of the functional protective film of the existing curved surface series mobile phone is to use the transparent conductive layer of indium tin oxide (ITO). Since ITO is fragile when cutting / punching, the wiring of the edge lead (conducting area) must be Keep away from the edge, which will block the touch icon or touch point on the display screen, resulting in local insensitivity or malfunction during normal touch operation of the mobile phone, seriously affecting the actual operating experience

Abstract

The invention discloses an intelligent curved-screen glass pasted-film and a preparation method thereof. The intelligent curved-screen glass pasted-film comprises a curved glass layer, a first adhesive layer, a graphene conducting layer, a PET film and a second adhesive layer. The curved glass layer includes an outer surface and an inner surface. The graphite conducting layer coheres with the inner surface of the curved glass layer through the first adhesive layer. One surface of the PET film is attached to the graphene conducting layer, and the other surface is provided with the second adhesive layer. Compared with traditional intelligent ITO three-layer-structure protection films, the intelligent pasted film of the invention has better advantages on all aspects of curved attachment, bending resistance ( the film can be repeatedly pasted on intelligent mobile phones many times) and the like, achieves an effective function protection film, and solves problems that an entire curved screen cannot be protected, and a conduction area shields touch control icons of a window area of a display screen, that is, the conduction area shields the touch control icons (also called virtual keys)on a touch function area (the window area) of the display screen and causes touch insensitivity.

Description

technical field [0001] The invention relates to an intelligent sticking film applied to curved screens 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 are currently one of the most popular smartphones among consumers. Since the 6plus series began to use curved screens, they have become very popular in the market, and mobile phones with curved screens have also ushered in rapid growth. [0004] Compared with the flat mobile phones of...
