The invention relates to the technical field of display screen decoration, in particular to a film for display screen decoration of a micro-die process and a manufacturing method thereof. Compared with the prior art, the method has the advantages of simpler flow, reduced production cost, lower film thickness, better quality, better texture visibility and aesthetic effect of the display.
Description
Technical Field
The invention relates to the technical field of display screen decoration, in particular to a display screen decorative film of a micro-die process and a manufacturing method thereof.
Background
As is well known, various types of display screens are provided in devices such as mobile phones, televisions, tablet computers, notebook computers, and refrigerators, and recently, the screen of the display tends to become larger, but on the contrary, the display tends to be thinner and lighter, and not only the internal characteristics but also the external characteristics of the device become very important. In order to prevent the display panel from being damaged and to protect the design of the color, texture, etc. of the display panel, a decorative cover is used on the surface of the display panel. The conventional decoration cap uses GDF (glass Direct film) method and gdm (glass Direct molding) method, but in the GDF method, although UV imprinting is performed on one PET film, recently, in order to form various fine textures (Pattern), a combination body of two PET films (PET films) after UV imprinting is used, which causes problems such as increase of defective rate, increase of personnel, increase of material price, increase of equipment investment, and reduction of production efficiency due to difficulty in mass production in the conventional process. In addition, since the final decorative cover is formed with a plurality of layers, the thickness of the final decorative cover is increased, and the visibility of the texture and the aesthetic quality of the display are inferior to those of the conventional 1-layer structure, and the unit of the fine texture is 1-100 nm and 1-1000 μm, and the unit of the fine texture is 10-1000 nm and 1-100 μm when the decorative film is used.
Disclosure of Invention
In order to solve the technical problems, the invention provides a film for decorating a display screen by a micro-mold process and a manufacturing method thereof, which solve the problems that the defect rate is increased, personnel is increased, the material price is increased, the equipment investment is increased and the existing process is difficult to produce in large quantities due to the fact that 2 types of PET films are combined after UV imprinting is carried out by two types of molds.
The film for decorating the display screen of the micro-mold process comprises a film main body, wherein the film main body is sequentially provided with a printing layer, an adhesion-promoting layer, a UV imprinting layer, a white glass fiber board layer and a film bottom layer from top to bottom.
The invention discloses a preparation method of a film for display screen decoration by a micro-mold process, which is characterized by comprising the following steps of:
(1) taking a white glass fiber board layer and a film bottom layer as a base layer, firstly making an external corner texture on the micro pattern and the resin for 2 times, then making an internal corner texture on the micro pattern and the resin for 1 time, then properly laminating, and forming a lamination structure after UV hardening;
(2) printing fine textures on the resin coated on the surface of the laminated structure in the step (1), and coating an adhesion-promoting layer on the surface of the resin after the resin is hardened;
(3) and coating a printing layer on the adhesion promoting layer.
Compared with the prior art, the invention has the beneficial effects that: compared with the prior art, the method has the advantages of simpler flow, reduced production cost, lower film thickness, better quality, better texture visibility and aesthetic effect of the display.

Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
Comparative example:
as shown in fig. 1 to 3, the film base layer is made of PET film material, resin is distributed on the film base layer, the micro pattern is hardened into UV resin, and the UV resin is laminated to form a 1-layer structure fine mold a, and after a mold real product manufactured by using the fine mold a is magnified by a microscope at 1000 times, the actual product structural line width is 46 μm;
the film bottom layer is made of PET film material, resin is distributed on the film bottom layer, the micro patterns are hardened into UV resin, the UV resin is laminated to form a fine die B, and after a die real product manufactured by the fine die B is amplified by a microscope at 1000 times, the structural line width of the real product is 73 microns;
the film bottom layer for the decoration of the display and the white glass fiber board layer are formed by laminating 2 times of UV imprinting, an adhesion-promoting layer, 1 time of UV imprinting, an adhesion-promoting layer and a printing layer in sequence.
The film base layer and the white glass fiber board layer are used for forming a material film of a display decorative film, and are made of polycarbonate + polymethyl methacrylate or other materials, and the 2-time UV embossed texture layer in the film base layer is formed on the base layer to be a curable resin.
After the resin is hardened and the printed texture A on the resin coated on the surface of the film bottom layer is subjected to the 1 st UV imprinting, thickening is carried out above the 1 st UV imprinting, and an emulsion is coated on a printed frame plate-making screen (polyester, nylon) so as to permeate into the middle of the screen.
Example (b):
as shown in fig. 4 to 5, fig. 4 is a mold structure (hereinafter referred to as a mold C) in which a conventional fine mold a + a fine mold B are combined, and the above-mentioned 2-pass UV imprinting method and resin are used for the bottom layer of the film, and the male-corner texture is first formed on the 2-pass fine pattern and resin, and the female-corner texture is formed on the 1-pass fine pattern resin, and then the mold C is formed by using the UV-hardened lamination structure through appropriate bonding, so that only one mold C is required, and in addition, the reliability, transmittance, and aesthetic property of the fine texture are increased, and the process or thickness of the film can be simpler and thinner than those of the conventional film through the step of forming the adhesion-increasing layer and the printing layer.
The actual product line width of the fine mold a is 46 μm, and the actual product line width of the fine mold B is 73 μm, and although the line widths are respectively located in the two molds, the mold C of the product of the present invention can be seen to be contained in the mold C at one time at 75 μm and 45 μm.
The film bottom layer for decorating the display screen, the white glass fiber board, the UV impression layer on the white glass fiber board, the adhesion promoting layer and the printing layer are laminated in sequence.
