The transparent shell 110 and the first film material 120, and the first film material 120 and the second film material 130 can be bonded by optical adhesive layers 101 and 102, respectively.

[0029] Specifically, the transparent shell 110 can be glass, transparent resin, etc., and the thickness can be 0.2-2 mm. The first film material 120 includes a first transparent substrate 121 and a first offset printing layer 122 provided on the first transparent substrate 121, wherein the transmittance of the first offset printing layer 122 is 25%-40%. The material of the first transparent substrate 121 can be transparent resin, such as PET, PMMA, etc.; and the thickness of the first transparent substrate 121 can be 20-80 um.

[0030] Optionally, the second film material 130 includes a second transparent substrate 131 and a second offset printing layer 132 provided on the second transparent substrate 131, and the transmittance of the second offset printing layer 132 is 20%-40%; the material of the second transparent substrate 131 can be transparent resin, such as PET, PMMA, etc.; and the thickness of the second transparent substrate 131 can be 20-80 um.

[0031] A light source 140 may be provided on the side of the second membrane material 130 away from the first membrane material 120. The light emitted by the light source 140 can pass through the second membrane material 130, the first membrane material 120 and the transparent shell 110 in sequence.

[0032] In the embodiments of this application, the shell achieves the purpose of blocking and allowing the internal texture and lighting effect pattern to pass through by designing the transmittance of the offset printing layer of the first film material and the second film material.

[0033] Please see Figure 2 , Figure 2 This is a schematic diagram of another embodiment of the housing of this application; the housing in this embodiment includes a transparent housing 110, a first membrane 120 and a second membrane 130 stacked in sequence.

[0034] The transparent shell 110 can be made of glass, transparent resin, etc., and its thickness can be 0.2-2mm. The first film material 120 includes a first transparent substrate 121, a first offset layer 122 disposed on the first transparent substrate 121, a first UV texture layer 123 disposed on the first offset layer 122, and an optical coating layer 124 disposed on the first UV texture layer 123.

[0035] The first offset printing layer 122 has a transmittance of 25%-40%. The first transparent substrate 121 can be made of transparent resin, such as PET or PMMA; the thickness of the first transparent substrate 121 can be 20-80 μm. The thickness of the first UV texture layer 123 can be 5-15 μm. The thickness of the optical coating layer 124 can be 0.1-0.5 μm.

[0036] Optionally, the transmittance of the first offset layer 122 gradually decreases from the center to the edge, with a transmittance of 25%-40% near the center and 0-10% near the edge.

[0037] Please see Figure 3 , Figure 3 This is a schematic flowchart of an embodiment of the preparation method of the first membrane material of this application. The preparation method of the first membrane material includes, but is not limited to, the following steps.

[0038] Step S110: Print a first offset layer on the first transparent substrate.

[0039] Specifically, the color original (taking a continuous-tone image as an example) can be input into a computer by scanning, digital photography, network transmission, etc., processed by image processing software such as Adobe Photoshop, Adobe Illustrator, CorelDraw, etc., and combined with text, graphics, etc. to form a layout, and finally recorded on a film or printing plate. The transmittance of the middle area of the first offset printing layer is a gradual effect, and the middle transmittance is 25-40%, gradually changing to 0 at the edge area.

[0040] The ink is uniformly transferred from the printing plate to the first transparent substrate 121 of the impression cylinder through the rubber blanket cylinder by the impression of the offset press, and the ultraviolet lamp in the offset press table irradiates the ink, causing the photoinitiator in the ink to undergo a polymerization reaction, causing the ink to dry instantly, and further forming the first offset printing layer 122.

[0041] Step S120, transferring a first UV texture layer on the first offset printing layer.

[0042] In this step, specifically, a first UV texture layer 123 can be transferred on the first offset printing layer 122 by a transfer machine.

[0043] Step S130, plating an optical plating layer on the first UV texture layer.

[0046]

[0047] Please refer to Figure 4 , Figure 4 is a structural schematic diagram of an embodiment of the first film material in the embodiment of the application.

[0048] Optionally, please continue to refer to Figure 2 The second film material 130 in the embodiment includes a second transparent substrate 131, a second offset printing layer 132 arranged on the second transparent substrate 131, a second UV texture layer 133 arranged on the second offset printing layer 132, and a hollow ink layer 134 arranged on the second UV texture layer 133.

[0049] The transmittance of the second offset printing layer 132 is 20%-40%. The material of the second transparent substrate 131 can be transparent resin, such as PET, PMMA, etc. The thickness of the second transparent substrate 131 can be 20-80 um. The thickness of the second UV texture layer 133 can be 5-15 um. The hollow ink layer 134 can be multi-layered (designed according to different patterns and light shielding requirements), and the thickness of each layer can be 5-15 um.

[0050] Optionally, the transmittance of the second offset printing layer 132 gradually decreases from the middle position to the edge position, the transmittance close to the middle position is 20%-40%, and the transmittance close to the edge position is 0-10%. The middle transmittance of the first offset printing layer 122 is 25%-40%, and the middle transmittance of the second offset printing layer 132 is 20%-40%.

[0051] Please refer to Figure 5 , Figure 5 is a flowchart of an embodiment of a preparation method of the second film material. The preparation method of the first film material includes but is not limited to the following steps.

[0052] In step S210, a second offset printing layer is offset printed on a second transparent substrate.

[0053] In this step, a color original (taking a continuous-tone image as an example) can be input into a computer by scanning, digital photography, network transmission, etc. The image processing software such as Adobe Photoshop, Adobe Illustrator, CorelDraw, etc. is used for processing, and the page layout is composed with text, graphics, etc. Finally, it is recorded on a film or printing plate. The transmittance of the designed second offset printing layer in the middle region is a gradual change effect, and the transmittance in the middle region is 20-40%, and the transmittance gradually changes to 0 in the edge region.

[0054] The ink is uniformly transferred from the printing plate to the second transparent substrate 131 on the impression cylinder through the rubber cylinder by the impression of the offset printing machine. The ultraviolet lamp in the offset printing machine irradiates the ink, so that the photoinitiator in the ink occurs polymerization reaction, the ink is instantaneously dried, and then the second offset printing layer 132 is formed.

[0055] In step S220, a second UV texture layer is transferred on the second offset printing layer.

[0056] In this step, a second UV texture layer 133 can be transferred on the second offset printing layer 132 by a transfer machine. In some other embodiments, an optical coating layer (not shown in the figure) can also be formed on the second UV texture layer 133. The specific formation method of the optical coating layer can be referred to the related description of the foregoing embodiments, which will not be described here.

[0057] Step S230, screen printing the hollow ink layer on the second UV texture layer.

[0058] Specifically, a screen printing plate with hollows can be made according to the effect drawing, and the ink is screen printed on the second UV texture layer 133, and baked at 80° for 30 minutes. Please refer to Figure 6 , Figure 6 is a structural schematic diagram of an embodiment of the second film material of the application.

[0059] Please continue to refer to Figure 2 , wherein the side of the second film material 130 away from the first film material 120 can be provided with a light source 140, and the light emitted by the light source 140 can pass through the second film material 130, the first film material 120 and the transparent shell 110 in turn.

[0060] The transmittance after offset printing will decrease, and the transmittance can be adjusted in the range of 0 to 100%. When the transmittance is in the range of 10-40%, the underlying layer of the offset printed layer has a certain shielding property, and the effect below can be seen when the light source at the bottom is turned on. We can use this feature to make a cmf (Color-Material-Finishing, which is an abbreviation of color, material and surface treatment) effect on the surface with a texture (first UV texture layer 123) that is obvious. When the light source 140 below is turned on, the cmf effect of the light source belt can be presented. In the actual processing process, the transmittance of the upper texture needs to be in the range of 20-30%, but the area of 20-30% of the light source 140 below is obviously transparent, at this time the transmittance needs to be reduced to 10-20%, so we divide the offset printing into two layers, the upper offset printing 25-40% mainly displays the texture of the upper layer and hides the effect below, and the lower offset printing 20-40% of the transmittance, when the light source 140 below is turned on, the other areas (the transmittance gradually changes near the edge area) are not transparent.

[0061] The embodiment of the application provides an effect scheme of a new type of electronic device shell (such as a mobile phone battery cover), which is normal and the texture effect on the surface is seen, similar to the normal battery cover effect. When the light source at the back is turned on, the light can pass through the hollows and the effect of the pattern of the light source and the hollow ink layer is presented.

[0062] In addition, the embodiment of the application also provides a preparation method of the shell, please refer to Figure 7 , Figure 7 is a flowchart of an embodiment of the shell preparation method of the application, and the shell preparation method includes but is not limited to the following steps.

[0063] Step S100, providing a transparent shell.

[0064] The transparent shell 110 can be glass, transparent resin, etc., which is not specifically limited here.

[0065] In step S200, the first film material is attached to the transparent shell.

[0066] In step S300, the second film material is attached to the first film material.

[0067] The detailed structure and preparation method of the first film material and the second film material are described in the foregoing embodiments, which will not be repeated here.

[0068] In the attachment process, the film can be sequentially torn off the release film and placed on the platform of the laminator, and the film material and the transparent shell are sequentially attached together by the laminator. In addition, the process of degassing is also included, and the gas between the film materials and the transparent shell is discharged by a high-pressure degassing machine with a degassing parameter of 50°, 16kpa, 30min.

[0069] The preparation method in the embodiment of the application realizes the purpose of shielding and transmitting the internal texture and light effect pattern by designing the transparency of the first film material and the second film material. Normally, the texture effect on the surface is seen, which is similar to the normal battery cover effect.
