These drawings and textual descriptions are not intended to limit the scope of the concept of the present disclosure by any means, but to illustrate the concept of the present disclosure to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0036] In order to make the purposes, technical solutions and advantages of the present disclosure clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0037] The foldable screen device is a new form of terminal device, and the foldable screen device has great advantages in miniaturization and portability. However, the foldable screen device is internally provided with a large rotating shaft, and the rotating shaft has strict restrictions on the overall structure in terms of layout, and the related antenna structure is also restricted.

[0038] In the related art, due to space limitations, the NFC antenna of a foldable screen device is basically arranged in the frame area of the foldable screen device. Since the foldable screen device has two states of unfolding and closing, the NFC antenna located in the frame area causes the user to need to adjust the handheld position and posture in a large range to correspond to the use of the NFC antenna in the unfolding and closing states respectively.

[0039] Taking a small foldable screen mobile phone (i.e., a foldable screen mobile phone with a small screen) as an example, the upper frame (i.e., the first area A in Figure 5 ) of the small foldable screen mobile phone or the side frame (i.e., the second area B in Figure 5 ) of the small foldable screen mobile phone is usually used as the NFC antenna of the device.

[0040] In the scenario where the first area A is used as the NFC antenna of the device, when the foldable screen device is unfolded, the first area A is located at the top of the device, and when the foldable screen device is closed, the first area A is located at the bottom of the device, and the relative position of the first area A in the device area changes greatly.

[0041] In the scenario where the second area B is used as the NFC antenna of the device, when the foldable screen device is unfolded, the second area B is basically not in the user's holding position, and when the foldable screen device is closed, the second area B is usually in the user's holding position.

[0042] The above two schemes of the NFC antenna located in the frame area cause the user to need to adjust the handheld position and posture in a large range to correspond to the use of the NFC antenna in the unfolding and closing states respectively when the foldable screen device is switched between different states, which is not conducive to the quick and convenient use of the NFC antenna by the user.

[0043] Embodiments of the present disclosure provide a display screen module, which can include a display layer 1, a first support layer 2, and an NFC assembly 3, as shown in Figure 1 .

[0044] The first support layer 2 is located on the side of the display layer 1 away from the light emitting direction and is connected to the display layer 1. The first support layer 2 has a receiving groove 2a. The first support layer 2 is used to provide support to the display layer 1, enhance the structural stability and durability of the display layer 1, and reduce the deformation or damage of the display layer 1 caused by external force.

[0045] The width of the receiving groove 2a is not specifically limited in the present disclosure and can be matched and set according to the width of the second support layer 31, the width of the NFC antenna 32, and the performance requirements of the NFC antenna 32.

[0046] The NFC assembly 3 includes a second support layer 31 and an NFC antenna 32 connected to each other. At least part of the second support layer 31 is located in the receiving groove 2a and is connected to the first support layer 2. The NFC antenna 32 is located on the side of the second support layer 31 away from the display layer 1.

[0047] This disclosure does not specify the connection method between the second support layer 31 and the NFC antenna 32. It can adopt a detachable connection method such as threaded fastening or snap-fit ​​connection, or a non-detachable connection method such as glue application or welding. The specific method can be matched and set according to the usage scenario of the display module and the structural strength requirements of different display modules for the NFC component 3.

[0048] By placing the NFC antenna 32 below the display layer 1, the relative position of the NFC antenna 32 in the device area does not change much when the foldable device is in different states. In this way, the user does not need to make large adjustments to the hand position and posture to use the NFC antenna 32 in the unfolded and closed states respectively, reducing the possibility that the NFC antenna 32 will not work effectively due to the user's grip on the foldable device.

[0049] In some embodiments, the first support layer 2 is a copper layer. Firstly, the copper layer provides electromagnetic compatibility (EMC) shielding, effectively blocking external electromagnetic interference (EMI) from affecting the display layer 1. This helps maintain the stability of the display signal and image quality, and also prevents electromagnetic signals generated inside the display module from leaking to the outside, thereby reducing interference to other electronic devices.

[0050] Secondly, the copper layer can serve as a grounding layer, effectively preventing static electricity accumulation, reducing electrostatic discharge (ESD) damage to the display screen, and providing a stable grounding path for various electronic components within display layer 1. This, in turn, helps stabilize the circuit, reduce noise, and improve the overall system reliability.

[0051] Thirdly, copper, as a material with good thermal conductivity, also helps dissipate heat. The copper layer can conduct heat to the outside of the foldable device through a preset channel, reducing the temperature inside the display layer 1 and thus extending the service life of the display layer 1.

[0052] In some embodiments, refer to Figure 2 As shown, the side of the second support layer 31 closest to the display layer 1 is flush with the side of the first support layer 2 closest to the display layer 1. On one hand, the flush alignment of the second support layer 31 and the first support layer 2 makes the area below the display layer 1 neater and more aesthetically pleasing, reducing user discomfort when touching or operating the display layer 1. This makes swiping or clicking smoother, reducing tactile sensation and visual differences, thereby improving the user experience.

[0053] On the other hand, the second support layer 31 and the first support layer 2 flush with each other can make the space below the display layer 1 effectively utilized, so that the foldable device is more compact, reducing unnecessary space waste, which is conducive to the miniaturization and portability design pursuit of the foldable device.

[0054] The depth size of the accommodation groove 2a is not specifically limited in the present disclosure, and can be matched and set according to parameters such as the number of layers and thickness of the second support layer 31, the thickness of the NFC antenna 32, and the like. Exemplarily, the side of the second support layer 31 away from the display layer 1 can be flush with the side of the first support layer 2 away from the display layer 1, or can not be flush.

[0055] In some embodiments, referring to Figure 2 Exemplarily, the width D of the accommodation groove 2a is equal to the width d1 of the second support layer 31, that is, in the width direction, the second support layer 31 sufficiently fills the accommodation groove 2a. In this way, the gap between the accommodation groove 2a and the second support layer 31 is avoided as much as possible, further reducing the foreign body sensation and visual difference in the user's tactile sensation, and improving the user experience.

[0056] In some embodiments, referring to Figure 2 and Figure 3 Exemplarily, the second support layer 31 includes an ink layer 311 and a polyester layer 312, and the distance between the ink layer 311 and the display layer 1 is less than the distance between the polyester layer 312 and the display layer 1.

[0057] The ink layer 311 has a certain insulating property, which can enhance the safety of the respective circuits of the display layer 1 and the NFC antenna 32. The polyester layer 312 can be made of PET (Polyethylene Terephthalate) material, which has excellent flexibility and does not have electromagnetic shielding function, thereby ensuring that the electromagnetic signals of the NFC antenna 32 can pass through the second support layer 31 and exchange data with other devices in the outside world.

[0058] In this way, by providing the accommodation groove 2a on the first support layer 2 (for example: copper skin layer) and filling the second support layer 31 into the accommodation groove 2a, on the one hand, the electromagnetic shielding effect of the first support layer 2 reduces the loss of the electromagnetic performance of the NFC antenna 32, and on the other hand, the setting of the second support layer 31 reduces the difference in visual and tactile sensation caused by the groove to the user, and also provides effective support to the display layer 1 corresponding to the accommodation groove 2a, avoiding the possibility of increasing damage and failure due to the existence of suspended space in the display layer 1.

[0059] In some embodiments, referring to Figure 3As shown, the width D of the accommodating groove 2a is greater than the width d2 of the NFC antenna 32, and the difference ranges from 1 mm to 3 mm. The first support layer 2 generally has electromagnetic shielding effect, and by providing the accommodating groove 2a with a certain avoiding space for the NFC antenna 32, the influence of the electromagnetic shielding function of the first support layer 2 on the working signal of the NFC antenna 32 can be reduced.

[0060] If the avoiding space of the accommodating groove 2a for the NFC antenna 32 is too small, for example, less than 1 mm, on the one hand, the processing precision requirement of the accommodating groove 2a and the assembly precision requirement of the accommodating groove 2a and the NFC antenna 32 are higher, thereby increasing the unqualified rate of the display screen module and the manufacturing cost of the display screen module.

[0061] If the avoiding space of the accommodating groove 2a for the NFC antenna 32 is too large, for example, greater than 3 mm, on the one hand, after the avoiding space exceeds a certain range, the quality of the working signal of the NFC antenna 32 no longer improves obviously, and on the other hand, the avoiding space being too large increases the amount of the second support layer 31 and the flatness requirement of the second support layer 31, thereby increasing the manufacturing cost of the display screen module.

[0062] In some embodiments, the accommodating groove 2a can be a straight groove with the bottom connecting the two side walls. In other embodiments, the accommodating groove 2a can also be a through groove composed of only two opposite side walls. The accommodating groove 2a can be specifically matched and set according to different application scenarios of the display screen module.

[0063] In some embodiments, referring to Figure 1 and Figure 2 As shown, the NFC antenna 32 has an open loop structure, that is, a ring structure with a notch. First, the open loop structure can optimize the current distribution and magnetic field enhancement. By introducing the notch, the current distribution in the NFC antenna 32 can be adjusted, so that the current produces a concentration effect at the notch, thereby enhancing the magnetic field strength of a specific area, and better controlling the distribution and direction of the magnetic field, so that the NFC antenna 32 can more effectively interact with other devices during communication.

[0064] Second, the notch design means that the NFC antenna 32 does not need a complete ring structure, thereby saving material cost and reducing production difficulty.

[0065] Third, the open loop structure has higher flexibility and adaptability, and the notch design provides greater flexibility for customization of the NFC antenna 32, which can be adjusted and optimized according to different application scenarios and different device requirements, and can better adapt to the internal space and layout requirements of the device.

[0066] In some embodiments, referring to Figure 3As shown, the distance between the first side wall 32a of the NFC antenna 32 and the side wall corresponding to the accommodating groove 2a is L1, the distance between the second side wall 32b of the NFC antenna 32 and the side wall corresponding to the accommodating groove 2a is L2, and the value range of L1 / L2 is 1:1-4:1, wherein the first side wall 32a is the side wall corresponding to the inner ring of the NFC antenna 32, and the second side wall 32b is the side wall corresponding to the outer ring of the NFC antenna 32.

[0067] In the NFC antenna 32, the electromagnetic field is more concentrated in the internal area of the antenna, and since the inner copper skin is closer to the center of the electromagnetic field, the current density is higher, and the influence on impedance matching, resonant frequency and signal strength is more significant. Therefore, the distance between the first side wall 32a of the NFC antenna 32 and the side wall corresponding to the accommodating groove 2a is L1≥ the distance between the second side wall 32b of the NFC antenna 32 and the side wall corresponding to the accommodating groove 2a is L2, which is more conducive to the interaction of the NFC antenna 32 with other devices during communication.

[0068] In some embodiments, referring to Figure 4 As shown, the first support layer 2 includes an inner side area 21, an outer side area 22 and a connecting area 23, and the two ends of the connecting area 23 are connected to the inner side area 21 and the outer side area 22 respectively.

[0069] In this way, the inner side area 21 does not need to be connected to other elements (such as a circuit board) of the foldable device, but is connected to the outer side area 22 through the connecting area 23, and meanwhile, the outer side area 22 has a corresponding connecting structure to realize the connection of the first support layer 2 with other elements and grounding.

[0070] The present disclosure does not make specific limitations on the connection mode of the connecting area 23 with the inner side area 21 and the connecting area 23 with the outer side area 22, and can adopt integral connection such as integral stamping, or detachable connection modes such as threaded fastening connection and buckle connection, or non-detachable connection modes such as glue dispensing and welding.

[0071] In some other embodiments, the first support layer 2 includes an inner side area 21 and an outer side area 22, and the inner side area 21 and the outer side area 22 can adopt the same or different connection modes to realize their respective connection with other elements (such as a circuit board and a middle frame) of the foldable device.

[0072] Based on the same principle, the present disclosure also provides a foldable device, which includes the display screen module according to any one of the first aspect.

[0073] The foldable device can include a main screen and a secondary screen, and the main screen and the secondary screen are located on opposite sides of the foldable device respectively, and the secondary screen includes the display screen module according to any one of the first aspect.

[0074] In this way, the NFC antenna 32 is arranged below the display layer 1 corresponding to the sub-screen, and the relative position of the NFC antenna 32 in the device area changes little in different states of the foldable device, so that the user does not need to adjust the handheld position and posture in a large range to correspond to the use of the NFC antenna 32 in the unfolded and closed states respectively, thereby reducing the possibility that the NFC antenna 32 cannot work effectively due to the user's shielding.
