Problems solved by technology

Especially for the development of 3D mobile phones. At present, in terms of 3D mobile phones, a large part of mobile phone manufacturers adopt the structure combining deco-film and glass substrate, and deco-film generally adopts a single-sided wire drawing structure, which is directly coated with optical glue. (Optically Clear Adhesive, referred to as OCA glue) is drawn on the PET, designed as a glare flat texture, its structure is PET+drawing+coating+ink, the process is drawing-coating-screen printing-cutting-bonding-degassing- The finished product is shipped. This kind of technology and design has been mass-produced for many years. The advantage is that the technology is mature. However, as more and more mobile phone manufacturers adopt it, the homogeneity of the appearance area is serious. Therefore, it is urgent to develop a glare three-dimensional texture. Meet the different needs of different customers

preparation example Construction

[0061] The preparation method of the above glass cover plate is to prepare the film film on the glass substrate to obtain the glass cover plate.

[0062] The glass cover plate with 3D glare effect can be obtained by laminating the film film and the glass substrate.

[0063] In some embodiments of the present invention, the first brushed layer and the first glare coating layer are sequentially prepared on one side of the transparent film substrate, and then the first glare coating layer is bonded with optical glue, and then the transparent The other surface of the film substrate is prepared in sequence with a second wire drawing layer, a second glare coating layer and an optional ink layer, and finally the optical glue is bonded to the glass substrate to obtain the glass cover plate.

[0064] In another aspect, the present invention provides an electronic device comprising the glass cover or the glass cover obtained by the above preparation method.

[0065] Wherein, electronic...

Embodiment 1

[0067] Such as figure 1 As shown, this embodiment is a film, including a PET film substrate 40, and the thickness of the PET film substrate 40 is 50 μm. Both sides of the PET film substrate 40 are respectively provided with a first wire-drawn layer 30 and a second wire-drawn layer 50, the surface of the first wire-drawn layer 30 is covered with the first glare coating layer 20, and the surface of the second wire-drawn layer 50 is covered with the second wire-drawn layer. Two glare coating layers 60 , the surface of the second glare coating layer 60 is provided with an ink layer 70 .

[0068] Wherein, the structure of the first glare coating layer 20 is Ti 3 o 5 / SiO 2 / Ti 3 o 5 , the thickness of the first glare coating layer 20 is 10nm / 35nm / 25nm.

[0069] The structure of the second glare coating layer 60 is Ti 3 o 5 / SiO 2 / In / Ti 3 o 5 . The thickness of the second glare coating layer 60 is 23nm / 70nm / 17nm / 50nm.

Embodiment 2

[0071] Such as figure 2 As shown, this embodiment is a glass cover plate, including a glass substrate 10 and the film film in Embodiment 1, the glass substrate 10 is connected with the first glare coating layer in the film film of Embodiment 1 through an optical glue OCA layer 11 20 fit. A glass substrate 10 is used as a substrate, on which an OCA layer 11, a first glare coating layer 20, a first drawing layer 30, a PET film substrate 40, a second drawing layer 50, a second glare coating layer 60 and ink are sequentially arranged. Layer 70.

Abstract

The invention provides a deco-film, a glass cover plate, preparation methods of the deco-film and the glass cover plate, and electronic equipment, and relates to the technical field of electronic equipment. The deco-film comprises a transparent film substrate; a first wiredrawing layer and a second wiredrawing layer are arranged on two sides of the transparent film substrate respectively; the surface of the first wiredrawing layer is covered with a first dazzle light coating layer; and the surface of the second wiredrawing layer is covered with a second dazzle light coating layer. The technical problem that appearance of dazzle light layers of deco-films in the prior art is seriously homogenized is solved, and the technical effect that the deco-film has different appearance dazzle light patterns is achieved.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a film film, a glass cover plate, a preparation method thereof, and an electronic equipment. Background technique [0002] With the explosive development of mobile phone covers, the appearance design of major mobile phone manufacturers is becoming more and more homogeneous. At present, differentiated appearance design is the pursuit direction of major mobile phone manufacturers. Especially for the development of 3D mobile phones. At present, in terms of 3D mobile phones, a large part of mobile phone manufacturers adopt the structure combining deco-film and glass substrate, and deco-film generally adopts a single-sided wire drawing structure, which is directly coated with optical glue. (Optically Clear Adhesive, referred to as OCA glue) is drawn on the PET, designed as a glare flat texture, its structure is PET+drawing+coating+ink, the process is drawing-coating-scree...
