[0028] In related technologies, the display screen structure on a smart phone case generally consists of a display screen, an FPC, and an NFC module, wherein the display screen and the NFC module are generally directly connected using an FPC (flexible printed circuit board). However, due to differences in the triggering positions of the NFC function of different models of mobile phones, in order to enable the display screen on the smart phone case to receive the display pattern signal sent by the mobile phone through the NFC module, it is necessary to design a different display screen structure according to the specific position of the NFC of each mobile phone. The product has poor versatility and is difficult to meet diverse market demands, which limits the market promotion and application scope of smart phone cases with displays.

[0029] In response to the above problems, an embodiment of the present application provides a display screen connection structure for a smart phone case, which can adapt to the production needs of different mobile phone models by setting a universal interface circuit board on the display screen, and by adapting different adapter flexible circuit boards and NFC modules, thereby improving the versatility of the product and enhancing the market promotion and application scope of smart phone cases with displays.

[0030] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0031] Figure 1 This is a structural schematic diagram of a display screen connection structure for a smartphone case shown in an embodiment of the present application.

[0032] See also Figure 1 The display screen connection structure for a smart phone case of the present application includes: a display screen 100, a transfer flexible circuit board 200 and an NFC module 300.

[0033] Display screen 100 is used to display patterns. A matching area 110 is provided on one side of display screen 100. It should be understood that "a side of display screen 100" can refer to any side of display screen 100. Matching area 110 is provided with an outwardly extending interface circuit board 120. One end of a transfer flexible circuit board 200 is connected to interface circuit board 120, and the other end of the transfer flexible circuit board 200 is connected to an NFC module 300. NFC module 300 is used to receive a display pattern signal sent by an external device via NFC technology and transmit the display pattern signal to display screen 100 via the transfer flexible circuit board 200, causing display screen 100 to display the corresponding pattern according to the display pattern signal.

[0034] In this embodiment, the display screen 100 itself has an interface circuit board 120. When the display screen connection structure is applied to smart phone cases adapted to different models of mobile phones, the corresponding transfer flexible circuit boards 200 can be equipped according to different mobile phone models, that is, different transfer flexible circuit boards 200 can be designed according to different mobile phone models, and then the transfer flexible circuit boards 200 are respectively connected to the interface circuit board 120 of the display screen 100 and the NFC module 300. In this way, the display screen connection structure can be applied to smart phone cases of different models of mobile phones. In the production process, when changing the production of different mobile phone models, it is only necessary to adaptively modify the transfer flexible circuit board 200 instead of redesigning the entire display screen connection structure, thereby effectively improving the versatility of the product and improving the market promotion and application scope of smart phone cases with display screens.

[0035] In some embodiments, the matching area 110 is located in the middle of the top of the display screen 100. It should be understood that the display screen 100 generally adopts a rectangular structure corresponding to the mobile phone case and is arranged along the length of the mobile phone case. Among them, the matching area 110 is located in the middle of the top of the display screen 100, so that the interface circuit board 120 extends outward from the middle of the top of the display screen 100. In this way, when adapting to smart phone cases of different mobile phone models, it is convenient to design different adapter flexible circuit boards 200 to adapt to the NFC positions corresponding to different mobile phones. It should be understood that when the interface circuit board 120 of the display screen 100 is fixedly set in the middle of the top and the display screen 100 is centered on the smart phone case, the position of one end of the adapter flexible circuit board 200 is relatively fixed, so that it is simpler and more convenient to design the connection between the other end of the adapter flexible circuit board 200 and the NFC module 300.

[0036] In some embodiments, the length of the interface circuit board 120 is shorter than that of the transfer flexible circuit board 200. The length of the transfer flexible circuit board 200 may refer to the extended length of the transfer flexible circuit board along its extension direction. This design allows for more space to be reserved for the layout of the transfer flexible circuit board 200. In some specific embodiments, the length of the interface circuit board 120 is 10 mm to 12 mm. It should be understood that due to the limited space within a smartphone case, an excessively long interface circuit board 120 will occupy too much space on the layout of the transfer flexible circuit board 200, affecting its proper placement. If the interface circuit board 120 is too short, it will be difficult to ensure a good connection with the transfer flexible circuit board 200. By increasing the length of the interface circuit board 120 to 10 mm to 12 mm, the impact on the layout of the transfer flexible circuit board 200 is effectively reduced, while ensuring a good connection between the interface circuit board 120 and the transfer flexible circuit board 200.

[0037] In some embodiments, the display screen 100 may be an electronic paper display screen. The electronic paper display screen has excellent energy-saving performance, which can enable the entire display screen connection structure to achieve excellent energy-saving performance. In particular, the electronic paper display screen has a bi-stable characteristic, and when the image is not being updated, the electronic paper display screen does not consume any power. Furthermore, when the display screen 100 is an electronic paper display screen, it can also be powered directly by the NFC module 300, so that the display screen connection structure of the present application no longer needs to be equipped with a dedicated power supply, effectively simplifying the design complexity of the display screen connection structure. The display screen 100 can adopt a black and white or color electronic paper display screen to meet the display content requirements of different users.

[0038] In some embodiments, one end of the transfer flexible circuit board 200 is pressure-welded to the interface circuit board 120. Corresponding gold fingers are pre-set on the transfer flexible circuit board 200 and the interface circuit board 120, and pressure welding is used to connect one end of the transfer flexible circuit board 200 to the interface circuit board 120. It should be understood that the pressure welding process itself is characterized by high strength and high reliability. This pressure welding process forms a strong electrical connection between the transfer flexible circuit board 200 and the interface circuit board 120, thereby effectively ensuring the stability of communication between the display screen 100 and the NFC module 300.

[0039] In some embodiments, one end of the transfer flexible circuit board 200 is connected to the interface circuit board 120 via a plug-in arrangement. This plug-in arrangement simplifies and swifts the connection between the transfer flexible circuit board 200 and the interface circuit board 120, improving production efficiency during product assembly. Furthermore, the use of a plug-in arrangement to connect the transfer flexible circuit board 200 to the interface circuit board 120 further enhances product versatility, allowing display screens 100 of the same specifications and models to be compatible with different transfer flexible circuit board 200 designs. Furthermore, the use of a plug-in arrangement facilitates subsequent product repair and replacement, reducing product maintenance costs.

[0040] Figure 2 This is another structural schematic diagram of the display screen connection structure for a smartphone case shown in an embodiment of the present application.

[0041] See also Figure 2 In some other embodiments, the transfer flexible circuit board 200 has at least two straight portions 210 and at least one curved portion 220 located between any two adjacent straight portions 210. It can be seen that the transfer flexible circuit board 200 has at least two straight portions 210 and at least one curved portion 220, so that the transfer flexible circuit board 200 can change the extension direction at least once, such as Figure 1 The intermediate flexible circuit board 200 changes its extension direction once, as shown in FIG. Figure 2 The transfer flexible circuit board 200 changes its secondary extension direction. It should be understood that smartphone cases are relatively compact environments. The combination of straight and curved sections of the transfer flexible circuit board 200 allows it to bypass other components, such as the battery, camera module, or other components, effectively improving product space utilization and preventing interference with other components caused by the display connection structure.

[0042] Corresponding to the aforementioned application function implementation device embodiment, the present application also provides a smart phone case and corresponding embodiments.

[0043] Figure 3 It is a schematic structural diagram of a smart phone case shown in an embodiment of the present application.

[0044] See also Figure 3 The smart phone case of the present application includes a mobile phone case body 2000 and a display screen connection structure 1000 described in the present application arranged on the mobile phone case body 2000.

[0045] In some embodiments, the NFC module 300 is located above the display screen 100, and the distance between the NFC module 300 and the display screen 100 along the length of the phone case body 2000 is greater than the length of the interface circuit board 120. It should be understood that the NFC module 30 generates a magnetic field of a certain strength when in operation. By ensuring that the distance between the NFC module 300 and the display screen 100 along the length of the phone case body 2000 is greater than the length of the interface circuit board 120, the intensity of the magnetic field generated by the NFC module 300 during operation on the display screen 100 can be significantly reduced, ensuring that the display screen 100 can operate in a stable electromagnetic environment and preventing display anomalies caused by magnetic field interference, such as image flickering, color distortion, or garbled display. By maintaining a sufficient distance (i.e., ensuring that the distance between the NFC module 300 and the display screen 100 along the length of the phone case body 2000 is greater than the length of the interface circuit board 120), the intensity of the magnetic field from the NFC module 300 on the display screen 100 can be significantly reduced, ensuring that the display screen 100 can operate in a stable electromagnetic environment, further improving the operational stability of the entire smartphone case.

[0046] In this embodiment, the display screen connection structure in the smart phone case can be suitable for different models of mobile phones. Therefore, during the production process, when changing the production of different mobile phone models, it is only necessary to adaptively modify the transfer flexible circuit board instead of redesigning the entire display screen connection structure, thereby effectively improving the versatility of the product and increasing the market promotion and application scope of the smart phone case with a display screen.
