CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority on the basis of Chinese Patent Application No. 201811427132.7 filed November 27, 2018 and incorporated herein by reference in its entirety.

FIELD OF TECHNOLOGY

[0002] The present invention relates to a camera shutter structure, namely a camera shutter, a camera shutter processing method, and a mobile terminal.

BACKGROUND OF THE INVENTION

[0003] Large screen mobile terminals are becoming more and more popular among users. As a result, major manufacturers are increasingly focusing on increasing the usable screen area of mobile terminals. However, in the face of increasing competition and investment volumes, further increase in the usable screen area of mobile terminals becomes a difficult task. In the future, one of the options for solving this problem may be mobile terminal devices with a two-sided screen, which does not require an increase in the size of the mobile terminal device.

[0004] The dual screen mobile terminal includes a main display screen and a secondary display screen located on both sides of the mobile terminal, respectively. The camera hole corresponding to the rear camera of the dual screen mobile terminal is on the same panel as the sub display screen and on one side of the sub display screen. Considering that both sides of the dual screen mobile terminal have display screens, as well as the design requirements of the device and camera protection, the dual screen mobile terminal includes a camera shutter. The camera shutter covers the opening of the camera, and the additional display screen is also covered by a part of the camera shutter. This part is made transparent and attached to an additional display screen.

[0005] Through optical refraction, the edge of the camera shutter refracts light, which forms a rainbow pattern on the secondary display screen. If you turn on the secondary display screen while using the device, the secondary display screen will show a distinct rainbow pattern along the edge of the camera shutter, which is a serious inconvenience.

[0006] Obviously, the camera shutter can also be applied to the main display screen. If a camera shutter is installed on the main display screen to protect the front camera, a rainbow pattern may also appear on the main display screen. However, this problem is not limited to mobile terminals with a two-sided screen. If a portion of the camera shutter is on the display screen of any mobile terminal device, then a rainbow pattern may form on the display screen of such mobile terminal device, which causes serious inconvenience.

SUMMARY OF THE INVENTION

[0007] The present invention includes a camera shutter that solves the problem of rainbow pattern formation on the display screen of a mobile terminal device.

[0008] To solve the above problem, the present invention uses the following technical solutions:

[0009] A camera shutter including:

a protective shutter housing containing a transparent area for covering the display screen;

a safety shutter edge, where the safety shutter edge and the safety shutter body form an integral structure, wherein the safety shutter edge surrounds the safety shutter body, and the portion of the safety shutter edge located outside the transparent area includes a frosted area.

[0010] A mobile terminal including a terminal body and a camera shutter, where the terminal body is provided with a camera opening, and the camera safety shutter is attached to the terminal body, covers the camera opening, and is the above-described camera safety shutter.

[0011] A method for processing a camera shutter, including:

application of protective acid-resistant ink on the surface of the protective shutter of the camera;

removal of protective acid-resistant ink from the edge of the protective shutter of the camera;

processing the matte area by chemical etching on the edge from which the protective acid-resistant ink is removed;

chemical polishing of the matte area;

removing the acid-resistant protective ink remaining on the edge of the camera's privacy shutter.

[0012] A method for processing a camera shutter, including:

processing of the matte area on the edge of the protective shutter of the camera by means of a laser;

physical polishing of the matte area.

[0013] The technical solutions presented in this invention can give the following technical effects:

[0014] The camera shutter of the present invention has an improved structure compared to a conventional camera shutter due to the presence of a frosted area, such that the portion of the edge of the security shutter outside the transparent area includes the frosted area. The frosted area can scatter and more evenly distribute the incident light, which will prevent the formation of a rainbow pattern on the display screen after passing through the frosted area, and eliminate the inconvenience to the user associated with the formation of the rainbow pattern.

DESCRIPTION OF EMBODIMENTS

[0021] In order to explain the objectives, technical solutions and advantages of the present invention, the technical solutions used in the embodiments of the present invention are clearly and fully described below with reference to the corresponding accompanying drawings. It is obvious that the described embodiments are possible, but not exhaustive for this invention. All other embodiments of the present invention, obtained by those skilled in the art based on the embodiments described without creative effort, are included in the scope of legal protection for this invention.

[0022] The technical solutions used in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] As shown in FIG. 1 and FIG. 2, some embodiments of the present invention implement a camera shutter, which is typically a glass shutter to protect the mobile terminal's camera.

[0024] Some embodiments of the present invention implement a camera shutter 100 including a camera shutter body 110 and a camera shutter edge 120. The camera shutter edge 120 and the camera shutter body 110 form an integral structure, with the safety shutter edge 120 surrounding the safety shutter body 110 The edge of the privacy shutter 120 includes a transparent area 111 covering the display screen, and the transparent area 111 does not affect the display of the corresponding portion of the display screen covered by the transparent area 111. The edge portion of the privacy shutter 120 outside the transparent area 111 includes a frosted area 121.

[0025] The camera shutter 100 described in some embodiments of the present invention has an improved structure compared to a conventional camera shutter due to the presence of a frosted area, such that the part of the edge of the security shutter 120 located outside the transparent area 111 includes a frosted area. 121. The frosted area 121 can scatter and more evenly distribute the incident light, which will prevent the formation of a rainbow pattern on the display screen after passing through the frosted area 121 and eliminate the inconvenience to the user associated with the formation of a rainbow pattern.

[0026] Typically, the camera shutter 100 protrudes above the display screen 210 of the mobile terminal. In order to improve ergonomics, the edge of the security shutter 120 may be rounded and beveled, and have a smooth and rounded surface without corners, so that the user can comfortably touch the security shutter of the camera 100.

[0027] As described above, the part of the edge of the security shutter 120 outside the transparent area 111 may include a frosted area 121. In particular, the outer side of the edge of the security shutter 120 behind the body of the security shutter 110 may be filled with a frosted area 121. B In this case, the outer side of the rounded and beveled edge will be the frosted area 121, and the inside of the rounded and beveled edge may be a smooth surface.

[0028] The edge of the security shutter 120 may include the frosted area 121 only outside the transparent area 111. Obviously, the edge of the security shutter 120 may include the frosted area 121 in all of its parts. In a certain embodiment of the present invention, the edge of the safety shutter 120 may be rounded and the frosted area 121 may be rounded and surround the housing of the safety shutter 110.

[0029] In general, the entire protective shutter of the camera 100, except for the transparent area 111, is located on the upper frame of the mobile terminal. A color ink layer 130 is applied to the body of the security shutter 110, which matches the color of the top frame and enhances the overall visual performance of the mobile terminal. In particular, the layer of color ink 130 may cover a portion of the body of the protective shutter 110 located on the frame of the mobile terminal. The color ink layer 130 may be light-transmitting or light-transmitting. The camera opening of the mobile terminal is usually located on the upper frame of the mobile terminal, and the portion of the protective shutter housing 110 opposite the camera opening is a transparent area so as not to degrade the camera performance of the mobile terminal.

[0030] Based on the camera shutter described above, some embodiments of the present invention implement a mobile terminal. Such a mobile terminal includes a terminal housing 200 and a camera shutter 100, the camera shutter 100 being attached to the terminal housing 200 and covering the camera opening. The camera security shutter 100 is the camera security shutter described in the above embodiment of the present invention.

[0031] In this embodiment of the present invention, the mobile terminal may be a single-sided screen mobile terminal or a double-sided screen mobile terminal. The mobile terminal device in this embodiment of the present invention may be a terminal device with a camera and a display screen, such as a smartphone, tablet computer, game console, or wearable device. The specific type of mobile terminal is not limited in the embodiments of the present invention.

[0032] In a specific implementation, the mobile terminal may be a mobile terminal with a two-sided screen, wherein the two-sided screen of the mobile terminal may include a main display screen and a secondary display screen located on both sides of the two-sided screen of the mobile terminal, respectively, and a privacy shutter The camera can be attached to the panel, on which the secondary display screen is located.

[0033] Based on the camera security shutter described above, some embodiments of the present invention implement a camera security shutter processing method. As shown in FIG. 3, the described processing method includes the following steps:

[0034] S101. Applying protective acid-resistant ink to the surface of the camera's protective shutter.

[0035] In this step, a protective acid-resistant ink is applied to the surface of the conventional camera shutter, which protects and prepares the camera shutter for subsequent processes so that subsequent processes do not damage the camera shutter in areas that are not to be treated. In general, at this stage, a protective acid-resistant ink is applied to the protective shutter of the camera using a printer. In particular, the layer thickness of the acid-resistant security ink may be about 10 μm. In particular, the printer can work with a screen printing pressure of 6 bar and a screen printing speed of 160 mm/s to 259 mm/s. After the screen printing is completed, the protective acid-resistant ink can be cured under temperature. In particular, curing can be carried out at a temperature of 160°C for 6 minutes.

[0036] S102. Removing the protective acid-resistant ink from the edge of the camera shutter.

[0037] The acid-resistant security ink applied in step S101 is partially removed so that the edge of the camera security shutter can be processed in subsequent step S103.

[0038] S103. Processing of the matte area by chemical etching on the edge from which the protective acid-resistant ink is removed.

[0039] At this stage, a chemical etching method is used to process the matte area on the edge of the camera shutter. In particular, the chemical etching method is a well-known technology and therefore is not described in detail here. In a specific embodiment, HF (hydrofluoric acid) is used as the pickling solution at a concentration of 4% to 9% and an pickling time of 90 seconds.

[0040] S104. Chemical polishing of the matte area.

[0041] At this point, the matte area treated in step S103 is chemically polished. In particular, for the purpose of chemical polishing, the matte area can be etched.

[0042] S105. Removing protective acid-resistant ink remaining on the edge of the camera's privacy shutter.

[0043] This step removes the protective acid-resistant ink remaining on the camera's protective shutter. There are many ways to remove protective acid-resistant ink. In a specific implementation, this step may include the following: first, heating the security acid-resistant ink remaining on the security shutter of the camera, and then rinsing the security acid-proof ink with clean water. In particular, the protective acid-resistant ink left on the camera's protective shutter can be heated at 65°C for 15 minutes. Flushing with clean water can be performed at 55°C for 2 minutes.

[0044] After completing the above steps from S101 to S105, a new camera shutter can be obtained. Unlike conventional camera shutters, the camera shutter obtained by the processing method described in some embodiments of the present invention has a frosted area at the edge.

[0045] Typically, the camera shutter is a glass plate. With this in mind, after step S105, the processing method may further include strengthening the camera shutter. For example, to increase the overall strength of the camera shutter, a hardening process involving the exchange of sodium ions within the camera shutter can be used.

[0046] As mentioned above, in order to make the camera shutter area located on the top frame of the mobile terminal be matched in color with the top frame, after reinforcing the camera shutter, the processing method may further include: covering the camera shutter area, located on the upper frame of the mobile terminal, where the part of the color ink layer corresponding to the camera hole is the outlet. The color ink layer matches the color of the top frame of the mobile terminal. In particular, the thickness of the color ink layer may be about 10 µm. In general, this process is performed by a screen printer with a 350 mesh screen plate under a screen printing pressure of 6 bar and a screen printing speed of 160 mm/s to 259 mm/s, where the thickness of the color ink layer is less than 15 µm. Obviously, the exit hole prevents the degradation of camera performance that could be caused by the color ink layer.

[0047] The camera shutter described in some embodiments of the present invention may alternatively be processed not by the above chemical treatment method, but by a physical treatment method. As shown in FIG. 4, some embodiments of the present invention include another method for processing a camera shutter. The method includes the following steps:

[0048] S201. Processing of the matte area on the edge of the protective shutter of the camera by means of a laser.

[0049] At this stage, the laser is used to laser process the edge of the camera shutter. In particular, such processing can be performed with a 10 W laser, a laser energy level of 5% to 40%, and a laser precision within 0.1 mm.

[0050] S202. Physical polishing matte area.

[0051] In this embodiment of the present invention, various physical polishing methods, such as manual polishing, can be used for polishing.

[0052] Similarly, after action S202, the processing method shown in FIG. 4 may further include the following: strengthening the camera shutter. The special enhanced processing is the same as the enhanced processing after step S105 described above.

[0053] Similarly, after strengthening the camera shutter, the processing method shown in FIG. 4 may further include the following: covering an area of a camera shutter located on the upper frame of the mobile terminal, where the part of the color ink layer corresponding to the camera opening is an exit hole. In particular, this step is consistent with the content of the analogue of the processing method shown in FIG. 3. Please refer to the corresponding description above for details.

[0054] The above embodiments of the present invention mainly describe the differences between the embodiments of the present invention. Non-contradictory improvement methods in various embodiments of the present invention can be combined to obtain the most preferred implementation. For brevity, the detailed description is not repeated herein.

[0055] The above descriptions are only some, but not exhaustive, embodiments of the present invention. Specialists in the art it is obvious that this invention can have many variations and variations. Any changes equivalent to substitutions and improvements that do not affect the essence and scope of the invention are included in the scope of legal protection for this invention and the claims of this invention.
