[0003] The present application relates to the technical field of electronic device design, and in particular, to an electronic device. BACKGROUND

[0004] At present, users have higher and higher requirements on the image performance of electronic devices. The light illumination and effect of the light compensation module of the electronic device are the basis for the electronic device to have good image performance.

[0005] In related technologies, the light compensation module of the electronic device includes a light emitting element and an optical cover. The light emitted by the light emitting element is transmitted after being dimmed by the optical cover. After the electronic device is assembled, the light illumination of the light emitting element and the dimming effect of the optical cover are determined. Thus, the light compensation brightness of the light compensation module cannot be adjusted on demand in the case of using the electronic device by the user, so that the light compensation effect of the light compensation module cannot meet the special needs of the user. SUMMARY

[0006] The electronic device provided by the embodiments of the present application includes a liquid crystal dimming film, a first circuit board, a light source assembly, an optical cover, and a camera decoration ring assembly. The liquid crystal dimming film includes a first electrode layer, a liquid crystal layer, and a second electrode layer which are sequentially stacked. The first electrode layer and the second electrode layer are electrically connected with the first circuit board. The liquid crystal molecules of the liquid crystal layer can be deflected under the action of the electric field between the first electrode layer and the second electrode layer. The liquid crystal dimming film is arranged on the camera decoration ring assembly. The optical cover is arranged between the light source assembly and the liquid crystal dimming film. The optical cover is used for making the light emitted by the light source assembly to be incident on the liquid crystal dimming film. The light incident on the liquid crystal dimming film can be transmitted through the liquid crystal dimming film and then transmitted through the camera decoration ring assembly.

[0007] The above technical solution adopted by the embodiments of the present application can achieve the following beneficial effects:

[0008] In the embodiment of the present application, during the photographing process of the photographing module, the light illumination and effect of the light emitted by the camera decoration ring assembly can be adjusted by adjusting the power supply state of the first electrode layer and the second electrode layer through the first circuit board. When the first electrode layer and the second electrode layer are in the power-on state, the liquid crystal molecules of the liquid crystal layer of the liquid crystal dimming film are arranged in order, and the light emitted by the optical cover to the liquid crystal dimming film can be emitted by the camera decoration ring assembly with high brightness under the transmission of the liquid crystal molecules. When the first electrode layer and the second electrode layer are in the power-off state, the liquid crystal molecules of the liquid crystal layer of the liquid crystal dimming film are arranged randomly, so that the light emitted by the optical cover to the liquid crystal dimming film can be emitted by the camera decoration ring assembly with soft brightness under the scattering of the liquid crystal molecules.

[0009] In addition, the liquid crystal dimming film is arranged in the camera decoration ring assembly, so that the liquid crystal dimming film and the camera decoration ring assembly can be integrated as a whole, so that a special mounting bracket does not need to be arranged for the liquid crystal dimming film, and the mounting structure and assembly process of the liquid crystal dimming film can be simplified.

Detailed Implementation

[0040] In order to make the objects, technical solutions and advantages of the present application clearer, the following will clearly and completely describe the technical solutions of the present application with reference to the specific embodiments and corresponding drawings of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0041] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium, can be the communication inside two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] In addition, although the terms used in the present application are selected from the commonly known and used terms, some terms mentioned in the description of the present application may be selected by the applicant according to his or her judgment, and the detailed meanings of which are described in the relevant part of the description.

[0043] In addition, the present application is required to be understood not only by the actual terms used, but also by the meaning implied by each term.

[0044] The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0045] The embodiments of the present application provide an electronic device. With reference to FIGS. 1 to 24, the electronic device 1 provided by the embodiments of the present application comprises a liquid crystal dimming film 10, a first circuit board 20, a light source assembly 30, an optical cover 40 and a camera decoration ring assembly 50.

[0046] The liquid crystal dimming film 10 comprises a first electrode layer 11, a liquid crystal layer 12 and a second electrode layer 13 which are sequentially stacked. The first electrode layer 11 and the second electrode layer 13 are both electrically connected with the first circuit board 20, and the liquid crystal molecules 121 of the liquid crystal layer 12 can be deflected under the action of the electric field between the first electrode layer 11 and the second electrode layer 13.

[0047] Exemplarily, the first circuit board 20 is a mainboard of the electronic device 1, and the first electrode layer 11 and the second electrode layer 13 are both electrically connected with the mainboard. Thus, the power supply of the electronic device 1 can supply power to the first electrode layer 11 and the second electrode layer 13 through the mainboard to form an electric field between the first electrode layer 11 and the second electrode layer 13, and then make the liquid crystal molecules 121 of the liquid crystal layer 12 deflect. In addition, the electronic device 1 can comprise a subboard. Exemplarily, the first circuit board 20 can also be a subboard of the electronic device 1.

[0048] Referring to FIG. 6, the liquid crystal molecules 121 of the liquid crystal light-adjusting film 10 are deflected under the action of the electric field between the first electrode layer 11 and the second electrode layer 13. As can be seen, when the first electrode layer 11 and the second electrode layer 13 are powered on, the liquid crystal molecules 121 are arranged in order. In this way, the deflection direction of the liquid crystal molecules 121 can be adjusted by adjusting the direction of the electric field between the first electrode layer 11 and the second electrode layer 13, so as to adjust the optical axis direction of the liquid crystal molecules 121, so that the electronic device 1 can emit light with higher brightness.

[0049] It should be noted that the liquid crystal molecules 121 of the liquid crystal light-adjusting film 10 can be liquid crystal molecules in the prior art. The liquid crystal molecules are substances between liquid and solid, which have the characteristic that the arrangement of the molecules can be controlled by the electric field. For example, the liquid crystal molecules 121 of the liquid crystal light-adjusting film 10 can be polymer dispersed liquid crystal (PDLC) or cholesteric liquid crystal.

[0050] In addition, referring to FIG. 7, when the first electrode layer 11 and the second electrode layer 13 are in a powered-off state, the liquid crystal molecules 121 are arranged randomly, so that the light is scattered under the action of the liquid crystal molecules 121, so that the electronic device 1 can emit light with softer brightness.

[0051] Further, in the embodiment of the present application, the liquid crystal light-adjusting film 10 is arranged in the camera decoration ring assembly 50. The optical cover 40 is arranged between the light source assembly 30 and the liquid crystal light-adjusting film 10, and the optical cover 40 is used to make the light emitted by the light source assembly 30 shoot towards the liquid crystal light-adjusting film 10. The light that shoots towards the liquid crystal light-adjusting film 10 can pass through the liquid crystal light-adjusting film 10 and be transmitted through the camera decoration ring assembly 50.

[0052] It should be noted that generally, the camera decoration ring assembly 50 can play a role of limiting the camera module of the electronic device 1, and a role of shielding the gap between the mounting hole on the shell of the electronic device 1 and the camera. It should be further noted that the structure of the camera decoration ring assembly 50 can refer to the related art, which will not be described here. In the embodiment of the present application, during the photographing process of the camera module, the light emitted by the light source assembly 30 can be transmitted through the liquid crystal light-adjusting film 10 and the camera decoration ring assembly 50, so as to perform light compensation.

[0053] In this way, by using the scheme provided in the embodiments of the present application, during the photographing process of the camera module, the light illumination and effect of the light emitted by the camera decoration ring assembly 50 can be adjusted by adjusting the power supply state of the first electrode layer 11 and the second electrode layer 13 through the first circuit board 20. When the first electrode layer 11 and the second electrode layer 13 are in the power-on state, the liquid crystal molecules 121 of the liquid crystal layer 12 of the liquid crystal dimming film 10 are arranged in order, and the light emitted by the optical cover 40 to the liquid crystal dimming film 10 can be emitted by the camera decoration ring assembly 50 with high brightness under the transmission of the liquid crystal molecules 121. When the first electrode layer 11 and the second electrode layer 13 are in the power-off state, the liquid crystal molecules 121 of the liquid crystal layer 12 of the liquid crystal dimming film 10 are arranged randomly, so that the light emitted by the optical cover 40 to the liquid crystal dimming film 10 can be emitted by the camera decoration ring assembly 50 with soft brightness under the scattering of the liquid crystal molecules 121.

[0054] In addition, the liquid crystal dimming film 10 is arranged on the camera decoration ring assembly 50, so that the liquid crystal dimming film 10 and the camera decoration ring assembly 50 can be integrated as a whole, thereby eliminating the need to provide a dedicated mounting bracket for the liquid crystal dimming film 10, and simplifying the mounting structure and assembly process of the liquid crystal dimming film 10.

[0055] It should be noted that how to electrically connect the first electrode layer 11 and the second electrode layer 13 of the liquid crystal dimming film 10 to the first circuit board 20 is a difficulty that needs to be solved in the use of the liquid crystal dimming film 10. In order to enable those skilled in the art to better implement the scheme provided in the embodiments of the present application, the specific electrical connection scheme between the first electrode layer 11 and the second electrode layer 13 and the first circuit board 20 is provided below for reference by those skilled in the art.

[0056] Referring to FIGS. 3-5, in some embodiments, the liquid crystal dimming film 10 is provided with a first electrical connection part 10a and a second electrical connection part 10b. The first electrical connection part 10a is electrically connected with the first electrode layer 11, and the second electrical connection part 10b is electrically connected with the second electrode layer 13. Further, the first electrode layer 11 is electrically connected with the first circuit board 20 through the first electrical connection part 10a, and the second electrode layer 13 is electrically connected with the first circuit board 20 through the second electrical connection part 10b.

[0057] For example, the first electrical connection part 10a can be a first conductive material layer electrically connected with the first electrode layer 11. For example, the first conductive material layer can be a silver layer. Further, for example, the first circuit board 20 can be connected with a flexible circuit board (FPC), and the flexible circuit board can be connected with the first conductive material layer through a bonding process, so that the first electrode layer 11 is electrically connected to the first circuit board 20 through the first conductive material layer and the flexible circuit board.

[0058] It should be noted that in the electronic field, the interconnection between electrode terminals and flexible circuits, the interconnection between flexible circuit boards and rigid circuit boards, and the interconnection between flexible circuits; anisotropic conductive adhesive (such as anisotropic conductive adhesive film) is widely used in these connections, which is placed between the components that need to be connected, and then pressure and heat are applied to form a stable and reliable mechanical and electrical connection between the components; this connection process is generally referred to as the bonding process. According to the process characteristics of the bonding process, the bonding process is also referred to as the hot-press welding process or the hot-press process by those skilled in the art.

[0059] In addition, the second electrode layer 13 can also be electrically connected to the first circuit board 20 in a similar manner, which will not be described here.

[0060] In this way, the liquid crystal dimming film 10 is provided with the first electrical connection part 10a electrically connected to the first electrode layer 11, so that the first electrode layer 11 can be more conveniently electrically connected to the first circuit board 20 through the first electrical connection part 10a by electrically connecting the first electrical connection part 10a to the first circuit board 20. The liquid crystal dimming film 10 is provided with the second electrical connection part 10b electrically connected to the second electrode layer 13, so that the second electrode layer 13 can be more conveniently electrically connected to the first circuit board 20 through the second electrical connection part 10b by electrically connecting the second electrical connection part 10b to the first circuit board 20.

[0061] Referring to FIG. 5, further, the liquid crystal dimming film 10 further includes a first light-transmitting substrate 14 and a second light-transmitting substrate 15. The first light-transmitting substrate 14 is arranged on the side of the first electrode layer 11 away from the liquid crystal layer 12, and the first electrical connection part 10a is arranged on the side of the first light-transmitting substrate 14 facing the first electrode layer 11. The second light-transmitting substrate 15 is arranged on the side of the second electrode layer 13 away from the liquid crystal layer 12, and the second electrical connection part 10b is arranged on the side of the second light-transmitting substrate 15 facing the second electrode layer 13.

[0062] The first electrical connection part 10a is arranged on the outside of the projection of the first electrode layer 11 on the first light-transmitting substrate 14; the second electrical connection part 10b is arranged on the outside of the projection of the second electrode layer 13 on the second light-transmitting substrate 15; so that the first electrical connection part 10a and the second electrical connection part 10b are both exposed to the outer surface of the liquid crystal dimming film 10.

[0063] In this way, the first electrical connection part 10a and the second electrical connection part 10b can be exposed to the outer surface of the liquid crystal dimming film 10, which can improve the convenience of electrically connecting the first circuit board 20 to the first electrical connection part 10a and the second electrical connection part 10b, respectively.

[0064] It should be noted that, for the liquid crystal dimming film 10, the first electrical connection part 10a and the second electrical connection part 10b are both exposed on the outer surface of the liquid crystal dimming film 10. However, for example, in the case where the first electrical connection part 10a and the second electrical connection part 10b are electrically connected with the flexible circuit board, the flexible circuit board can cover the surface of the first electrical connection part 10a and the second electrical connection part 10b, so that the first electrical connection part 10a and the second electrical connection part 10b are shielded by the flexible circuit board. Thus, the first electrical connection part 10a and the second electrical connection part 10b being exposed on the outer surface of the liquid crystal dimming film 10 does not mean that the first electrical connection part 10a and the second electrical connection part 10b cannot be shielded by any other structure.

[0065] In the above examples, the structure of the liquid crystal dimming film 10 is mainly introduced for the reference of those skilled in the art, and the following provides a scheme for connecting the liquid crystal dimming film 10 and the first circuit board 20 for the reference of those skilled in the art.

[0066] Referring to FIG. 17, in some embodiments, the light source assembly 30 includes a second circuit board 31 and a light emitting element 32 arranged on the second circuit board 31. The second circuit board 31 is electrically connected with the first circuit board 20. Exemplarily, the second circuit board 31 can be a flexible circuit board or a rigid circuit board. The light emitting element 32 can be a light emitting diode (LED).

[0067] In some embodiments, the electronic device 1 further includes a second flexible circuit board 72 and a fifth electrical connector 63. The second circuit board 31 is electrically connected with the second flexible circuit board 72, and the second flexible circuit board 72 is electrically connected with the fifth electrical connector 63. Further, the fifth electrical connector 63 is electrically connected with the first circuit board 20. So that the second circuit board 31 is electrically connected with the first circuit board 20 through the second flexible circuit board 72 and the fifth electrical connector 63.

[0068] Exemplarily, in the case where the second circuit board 31 is a flexible circuit board, the second flexible circuit board 72 can be integrally connected to the second circuit board 31. Exemplarily, the fifth electrical connector 63 can be a board-to-board connector plug, and the second circuit board 31 is provided with a board-to-board connector seat, so that the second circuit board 31 is electrically connected with the first circuit board 20 through the second flexible circuit board 72 and the fifth electrical connector 63 by means of the board-to-board connector plug and the board-to-board connector seat being docked.

[0069] Further, the first electric connecting part 10a and the second electric connecting part 10b are both electrically connected with the second circuit board 31, so that the first electrode layer 11 and the second electrode layer 13 are electrically connected to the first circuit board 20 through the second circuit board 31. Thus, on the basis of the electronic device in the related art, the liquid crystal dimming film 10 and the connecting line connecting the liquid crystal dimming film 10 and the second circuit board 31 are added, so that the problem of how to improve the light illumination brightness of the light compensation module and the problem of the effect being unable to be adjusted as needed can be solved while the electronic device in the related art is changed as little as possible.

[0070] Hereinafter, specific schemes in which the first electrode layer 11 and the second electrode layer 13 are electrically connected to the second circuit board 31 are provided for the person skilled in the art.

The first electric connector 61 is electrically connected with the second electric connector 62, so that the first electrode layer 11 and the second electrode layer 13 are both electrically connected with the second circuit board 31.

[0072] Exemplarily, the first electric connector 61 is a Zero Insertion Force (ZIF) connector terminal, and the second electric connector 62 is a ZIF connector seat body. Exemplarily, the second electric connector 62 can be arranged on the second circuit board 31 and electrically connected with the second circuit board 31, or the second electric connector 62 can be electrically connected with the second circuit board 31 through a flexible circuit board.

Thus, the first electric connecting part 10a and the second electric connecting part 10b can be respectively electrically connected with the first electric connector 61 through the first flexible circuit board 71. Further, the first electric connecting part 10a and the second electric connecting part 10b can be electrically connected with the first circuit board 20 by connecting the first electric connector 61 and the second electric connector 62.

[0074] It should be noted that, with reference to FIGS. 3-5, 8 and 9, the first flexible circuit board 71 is exemplarily provided with a fifth electrical connection part 711 and a sixth electrical connection part 712. The fifth electrical connection part 711 is electrically connected with the first electrical connection part 10a via a first anisotropic conductive film (ACF) 713. Specifically, the fifth electrical connection part 711 and the first electrical connection part 10a can be connected by a bonding process.

Specifically, the sixth electrical connection part 712 and the second electrical connection part 10b can be connected by a bonding process.

[0075] Exemplarily, for the above scheme, the liquid crystal dimming film 10 with the first flexible circuit board 71 and the first electrical connector 61 connected thereto can be purchased from a supplier of the liquid crystal dimming film 10. In other words, the supplier of the liquid crystal dimming film 10 can be requested to connect the first flexible circuit board 71 provided with the first electrical connector 61 to the liquid crystal dimming film 10 by a bonding process. Further, the second electrical connector 62 can be soldered on the second circuit board 31. Further, the first electrode layer 11 and the second electrode layer 13 can be electrically connected with the second circuit board 31 by connecting the first electrical connector 61 and the second electrical connector 62.
