[0002] With the upgrading of electronic devices, current users have higher and higher requirements for electronic devices to be lighter, thinner and smaller, especially for some wearable electronic devices, such as smart watches, sports watches, smart bracelets, etc.

[0003] However, as the size of electronic devices becomes smaller, the space reserved for batteries in electronic devices becomes smaller and smaller, which brings great challenges to the battery life of electronic devices and even makes it difficult to meet the battery life requirements of electronic devices.

[0004] It can be seen that the existing technology has the problem of difficulty in balancing the miniaturization of electronic devices and the battery life. Summary of the invention

[0005] The present application provides a screen assembly, a preparation method and an electronic device, which solve the problem of the difficulty in balancing the miniaturization and battery life of electronic devices in the prior art.

[0006] The screen assembly provided in the present application includes a solar cell module and a display screen, wherein the solar cell module is used to power the electronic device, and the display screen has a display area capable of displaying images and a non-display area arranged around the display area. The solar cell module includes a plurality of solar cells, which are distributed in a ring shape in the non-display area of ​​the display screen, and there is a gap between two adjacent solar cells in the plurality of solar cells, and a first concave lens is arranged in the gap to refract sunlight irradiated on the first concave lens onto the solar cell.

[0008] Furthermore, in the screen assembly of the present application, a first concave lens is arranged in the gap between two adjacent solar cells in the solar cell module. Through the first concave lens, sunlight irradiated in the gap (or can be understood as not directly irradiated on the solar cell) can be refracted onto the solar cell, thereby making full use of the limited space to improve the light conversion efficiency of the solar cell and improve the power supply capacity of the solar cell module, which is beneficial to improving the battery life of the electronic device.

[0009] In some embodiments, the solar cell module also includes a second concave lens, which is arranged on the inner and / or outer sides of the annular structure formed by multiple solar cells and is located in the non-display area of ​​the display screen to refract sunlight irradiated on the second concave lens onto the solar cell.

[0010] In the screen assembly of the embodiment of the present application, the solar cell module can refract sunlight irradiated on the inner side and / or outer side of a plurality of solar cells (or can be understood as not directly irradiated on the solar cell) onto the solar cell through a second concave lens arranged on the inner side and / or outer side of a plurality of solar cells, thereby further improving the light conversion efficiency of the solar cell and the power supply capacity of the solar cell module, which is beneficial to improving the battery life of the electronic device.

The transparent structural member is a plastic material layer, the plastic material layer is fixed to the circuit board and the plurality of solar cells are sealed in the plastic material layer.

[0017] In the screen assembly of the embodiment of the present application, the solar cell module uses a plastic encapsulation material layer as a transparent structural member for forming a first concave lens and a second concave lens, and uses the plastic encapsulation material layer to seal and encapsulate multiple solar cell sheets. Alternatively, it can be understood that the embodiment of the present application directly forms the first concave lens and the second concave lens on the plastic encapsulation material layer used to encapsulate the solar cell module, which simplifies the multi-layer stacking structure and processing process of the solar cell module and is low-cost.

[0018] In some embodiments, the circuit board is provided with a charging pad, and the charging pad is used to be electrically connected to a charging circuit of an electronic device to power the electronic device through a plurality of solar cells.

[0019] In some embodiments, the surface of the circuit board is a black rough surface.

[0020] In the screen assembly of the embodiment of the present application, the solar cell module uses a circuit board with a black rough surface, which can effectively prevent the circuit board from reflecting light (such as sunlight) and thereby affecting the light conversion efficiency of the solar cell, which is beneficial to improving the power supply capacity of the solar cell module.

[0021] In some embodiments, there are a plurality of first concave lenses and a plurality of second concave lenses in each gap, and the plurality of first concave lenses and the corresponding plurality of second concave lenses in each gap are distributed in a T-shape.

[0022] In the screen assembly of the embodiment of the present application, there are multiple second concave lenses and multiple first concave lenses in each gap, and the multiple first concave lenses in each gap and the corresponding multiple second concave lenses are distributed in a T shape. Such a structure can make full use of the narrow space in the non-display area of ​​the electronic device and arrange more concave lenses, thereby refracting more sunlight that is not directly irradiated on the solar cell onto the solar cell, so as to maximize the power supply capacity of the solar cell module, thereby helping to improve the battery life of the electronic device.

[0025] The solar cell module, the display panel and the transparent cover are fixed together.

[0026] In the screen assembly of the embodiment of the present application, since the solar cell module is arranged on the periphery of the display panel, it can avoid the display area of ​​the display screen to avoid affecting the display effect of the display screen.

[0027] In some possible embodiments, the solar cell module, the display panel and the transparent cover are bonded together.

[0028] An embodiment of the present application also provides an electronic device, including the screen assembly involved in the above-mentioned embodiments and possible embodiments.

[0029] The electronic device of the embodiment of the present application, by setting a solar cell module on the periphery of the display panel (or which can be understood as the non-display area of ​​the display screen), can use the solar cell module to power the electronic device without changing the size of the electronic device, without increasing the original battery capacity of the electronic device and without affecting the display effect of the display screen, thereby improving the battery life of the electronic device.

[0035] A first concave lens is manufactured on a transparent structural member by adopting a vacuum lamination technology or a nano-imprinting technology to form a solar cell module, wherein the first concave lens is located in the gap.

[0036] The solar cell module is installed in the non-display area of ​​the display screen to form a screen assembly.

[0037] In the preparation method of the screen assembly of the present application, since the first concave lens is directly formed on the transparent structural part by using vacuum pressing technology or nano-imprinting technology, compared with the solution of setting the first concave lenses one by one in the gap, the present application can form multiple first concave lenses at one time, with simple process, high processing efficiency and low cost. Moreover, since the transparent structural part is plastic-sealed on the solar cell sheet by using the plastic sealing process, it can not only serve as a carrier of the first concave lens, avoiding the possible easy falling off phenomenon when the first concave lens is separately bonded in the gap, but also can play a role in sealing and protecting the solar cell sheet, which is beneficial to improving the reliability and service life of the screen assembly.

[0038] In some embodiments, after the first concave lens is produced on the transparent structural member by using vacuum lamination technology or nanoimprinting technology, the method for preparing the screen assembly also includes: producing a second concave lens on the transparent structural member by using vacuum lamination technology or nanoimprinting technology, wherein the second concave lens is located on the inner side or outer side of the annular structure formed by multiple solar cells.

The shape of the solar cell 11 is not limited, and it can be rectangular, polygonal, irregular, etc. The distribution of the multiple solar cells 11 is not limited, and the design can be adjusted according to the shape of the display screen.

The solar cell 11 can be soldered to the corresponding soldering pad of the circuit board 12 through the soldering pad 110 using SMT (Surface Mount Technology) technology (or can be understood as flip-chip soldering technology), thereby achieving electrical connection with the circuit board 12. In one embodiment, electrical signal I / O points can also be set on the upper and lower surfaces of the solar cell 11 and electrically connected to the circuit board 12 by welding leads.

[0089] In one embodiment, the surface of the circuit board 12 is a black rough surface, for example, a blackening treatment can be performed by coating a rough surface ink material on the surface of the circuit board 12. Those skilled in the art will appreciate that other methods can also be used for blackening treatment.

[0090] The solar cell module 1 in the embodiment of the present application uses a circuit board 12 with a black rough surface, which can effectively prevent the circuit board from reflecting light (such as sunlight) and thus affecting the light conversion efficiency of the solar cell, which is beneficial to improving the power supply capacity of the solar cell module 1.

The transparent protective layer plays a role of waterproofing, sealing and protecting the transparent structural member 13 and the plurality of solar cells 11.

[0092] In one embodiment, if Figure 3 to Figure 5As shown, the transparent structural member 13 is a plastic encapsulation material layer, which is fixed to the circuit board 12 and multiple solar cells 11 are sealed in the plastic encapsulation material layer, which plays a role in protecting and waterproofing the solar cells 11. Or it can be understood that: in this embodiment, the transparent structural member 13 not only serves as a carrier for forming the first concave lens 131 and the second concave lens 132, but is also reused as a transparent protective layer for the solar cells 11. Among them, the plastic encapsulation material layer can be plastic encapsulated in multiple solar cells 11 and then fixed to the circuit board 12, or it can be bonded to the circuit board 12 by dispensing glue.

Alternatively, it can be understood that the embodiment of the present application directly forms the first concave lens 131 and the second concave lens 132 on the plastic encapsulation material layer used to encapsulate the solar cell sheet 11, and reuses the transparent structural member 13 as a transparent protective layer, thereby simplifying the multi-layer stacking structure and processing process flow of the solar cell module 1, and reducing the cost.

[0094] In one embodiment, a layer of light-transmitting film with a light-concentrating effect may be further provided on the surface of the transparent structural member 13 facing the sunlight, so that the sunlight can be better irradiated on the solar cell 11 , and this application does not limit this.

Among them, the area where the display panel 211 is located can be understood as the display area mentioned above, and the area outside the display panel 211 on the display screen 21 can be understood as the non-display area mentioned above. The transparent cover plate 212 can be, for example, CG (Curved Glass).

[0097] The solar cell module 1 is arranged on the periphery of the display panel 211 (or can be understood as the area outside the display panel 211 on the display screen 21), the transparent cover 212 covers the display panel 211 and is located on the side of the solar cell module 1 facing the sunlight, and the solar cell module 1, the display panel 211 and the transparent cover 212 are fixed together. In one embodiment, the solar cell module 1, the display panel 211 and the transparent cover 212 are bonded together, and in other alternative embodiments, other fixing methods may also be used.

[0098] In the screen assembly 2 of the embodiment of the present application, since the solar cell module 1 is arranged on the periphery of the display panel 211, it can avoid the display area of ​​the display screen 21 to avoid affecting the display effect of the display screen.

[0099] In one embodiment, the thickness of the solar cell module 1 does not exceed the thickness of the display panel 211 , which helps to match the solar cell module 1 with the display screen 21 and does not affect the overall thickness of the screen assembly 2 .

Taking a smart watch, a sports watch or a smart bracelet as an example, the electronic device 3 includes an outer frame 32. In one embodiment, the screen assembly 2 is mounted on the outer frame 32. The electronic device 3 also includes a flexible circuit board 31, which electrically connects the solar cell module 1 with the charging circuit (not shown) of the electronic device.

[0102] The electronic device of the embodiment of the present application, by setting a solar cell module 1 on the periphery of the display panel 211 (or can be understood as the non-display area of ​​the display screen 21), can use the solar cell module 1 to power the electronic device without changing the size of the electronic device, without increasing the original battery capacity of the electronic device and without affecting the display effect of the display screen, thereby improving the battery life of the electronic device. For electronic devices with high miniaturization requirements such as smart watches and sports watches, the battery life can be improved by 10% to 50%, and the benefits are better in outdoor sports scenes.

[0103] See also Figures 9 to 12 , Figures 9 to 12 This is a schematic diagram of the process flow of integrating a solar cell module into an electronic device according to an embodiment of the present application.

[0104] The present application provides a method for preparing a screen assembly, comprising:

[0105] Step S1: electrically connecting a plurality of solar cells to a circuit board, wherein a gap exists between two adjacent solar cells among the plurality of solar cells.

[0106] Specifically, for example, a circuit board 12 (such as Fig. 9 The solar cell module 1 is provided with a plurality of related components, such as a solar cell 11 and a transparent structural member 13. Then, the solar cell 11 is soldered to the circuit board 12 (such as a solar cell module 11) by flip-chip soldering or face-up soldering. Fig.10 shown).

[0107] Step S2: using a plastic encapsulation process to plastic encapsulate the transparent structural member on the surface of the plurality of solar cells facing the sunlight.

[0108] Specifically, for example, the solar cell 11 is plastic-sealed in the transparent structural member 13 (such as Fig.11 shown).

[0109] Step S3: using vacuum lamination technology or nano-imprinting technology to manufacture a first concave lens on the transparent structural member to form a solar cell module, wherein the first concave lens is located in the gap.

[0110] After the first concave lens is manufactured on the transparent structural member by using vacuum lamination technology or nanoimprint technology, step S4 may also be included: manufacturing a second concave lens on the transparent structural member by using vacuum lamination technology or nanoimprint technology, wherein the second concave lens is located on the inner circumference or outer circumference of the annular structure formed by multiple solar cells.

[0111] Specifically, for example, a first concave lens and / or a second concave lens may be manufactured on the transparent structural member 13 . The manufacturing process is not limited. For example, vacuum lamination technology or nano-imprinting technology may be used.

[0112] Step S5: installing the solar cell module in the non-display area of ​​the display screen to form a screen assembly.

[0113] In one embodiment, the display screen includes a display panel and a transparent cover plate, and step S5 may include:

[0114] Step S51: placing a solar cell module on the periphery of the display panel.

[0115] Step S52: fix the transparent cover plate to the side of the display panel facing the sunlight and / or the transparent structural member.

[0116] Specifically, for example, the display screen 21 (including the display panel 211 and the transparent cover plate 212) and the solar cell module 1 are integrated together, for example, they can be bonded together, and finally, the solar cell module 1 and the display screen 21 and the outer frame 32 of the electronic device are integrated together (such as Figure 8 shown).

[0117] Furthermore, the charging pad 120 of the solar cell module 1 can be interconnected with the charging circuit of the electronic device using the flexible circuit board 31 (eg Fig.12 shown).

[0118] In the preparation method of the screen assembly of the present application, since the first concave lens is directly formed on the transparent structural part by using vacuum pressing technology or nano-imprinting technology, compared with the solution of setting the first concave lenses one by one in the gap, the present application can form multiple first concave lenses at one time, with simple process, high processing efficiency and low cost. Moreover, since the transparent structural part is plastic-sealed on the solar cell sheet by using the plastic sealing process, it can not only serve as a carrier of the first concave lens, avoiding the possible easy falling off phenomenon when the first concave lens is separately bonded in the gap, but also can play a role in sealing and protecting the solar cell sheet, which is beneficial to improving the reliability and service life of the screen assembly.

[0119] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
