Description

Technical Field

[0001] This utility model relates to the field of NFC components, specifically an under-screen NFC component with grooves cut into the screen's metal interference material. Background Technology

[0002] Currently used under-screen NFC antennas have poor overall field strength distribution, making them unsuitable for financial authentication tests and lacking sufficient card reading distance, thus requiring improvement. Utility Model Content

[0003] The purpose of this invention is to provide an under-display NFC component with slots in the screen's metal interference material, in order to solve the problems mentioned in the background art. It has the advantages of effectively improving the strength of the NFC field, improving the accuracy of testing and certification, and more effectively improving the actual use effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an under-display NFC component with slots in the screen's metal interference material, comprising a screen display layer with metal interference material and an NFC antenna, wherein the screen's metal interference material is located below the screen display layer, the metal interference material has at least one slot, the NFC antenna is placed below the metal interference material and is in contact with or separated from the metal interference material by a distance of 1-2 mm, and the NFC antenna coil has at least one turn.

[0005] Preferably, the metal interference material is made of iron, the groove is rectangular or slit-shaped, and the depth of the groove extends through the entire thickness of the metal interference material.

[0006] Preferably, the NFC antenna is made of either FPC material or copper wire, and its coil position is perpendicular to the direction of the slot extension.

[0007] Preferably, when the NFC antenna uses copper wire winding, a small section of FPC material can be connected to its feed point as its feed point, and the FPC antenna can be connected to the motherboard spring through any slot to form a circuit.

[0008] Preferably, the NFC antenna placement area is at least 3mm away from one end of the screen cable on the metal interference material, the slot is in the remaining edge area of ​​the interference material, and the slot is close to the NFC antenna area.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] The metal interference material is made of iron, which severely interferes with the performance of the NFC antenna. After slotting, the strength of the NFC field is effectively improved, the accuracy of testing and certification is improved, and the actual use effect is improved. The slot is made on the part of the screen near the NFC antenna, which breaks the closed area of ​​the external metal and reduces the interference of the closed metal on the NFC field strength.

[0014] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] In this embodiment of the utility model,

[0016] An under-display NFC component with slots for interfering metal materials on the screen, such as Figures 1-2 As shown, the screen display layer 2 includes a screen display layer 2 with a metallic interference material 4 and an NFC antenna 3. The metallic interference material 4 is located below the screen display layer 2 and has at least one slot 1. The NFC antenna 3 is positioned below the metallic interference material 4 and is either in contact with it or at a distance of 1-2 mm from it. The NFC antenna 3 has at least one coil. A non-metallic area 5 is provided in the middle of the screen display layer 2.

[0017] The metal interference material 4 is made of iron, and the shape of the slot 1 is set to rectangular or slit-shaped. The depth of the slot 1 extends through the entire thickness of the metal interference material 4.

[0018] The NFC antenna 3 is made of either FPC material or copper wire, and its coil position is perpendicular to the extension direction of the slot 1.

[0019] When the NFC antenna 3 is made of copper wire, a small section of FPC material can be connected to its NFC antenna feed point 6 as its feed point. The FPC antenna is connected to the motherboard spring through any slot 1 to form a circuit.

[0020] The NFC antenna 3 is placed at least 3mm away from the end of the screen cable on the metal interference material 4. The slot 1 is located on the remaining side of the interference material and is close to the area of ​​the NFC antenna 3.

[0021] Working principle:

[0022] The metal interference material 4 is made of iron, which seriously interferes with the performance of the NFC antenna 3. After slotting 1, the strength of the NFC field is effectively improved, the accuracy of testing and certification is improved, and the actual use effect is improved. Slotting 1 on the part of the screen near the NFC antenna 3 breaks the closed area of ​​the external metal and reduces the interference of the closed metal on the NFC field strength.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
