In some possible implementations, the back-off window 1101 corresponds to a pattern position of the NFC tag 2, so that the NFC tag 2 may transmit and receive electromagnetic waves using the back-off window 1101.
In some possible implementations, the NFC tag 2 may store and transmit data, such as contact information or commands, and may be used for various applications, such as mobile payment, access control, marketing, or automation.
The NFC tag 2 communicates with a frequency of 13.56MHZ, for example.
As shown in connection with fig. 3, in some embodiments, an insulating fill 1102 is provided within the relief window 1101.
Considering that the metal layer 11 in the display screen 1 generally has a function of providing protection to the display screen 1 by using its own strength, the insulating material is filled in the avoiding window 1101, and the insulating material can compensate for the strength loss of the metal layer 11, so as to ensure the protection effect of the display screen 1.
Illustratively, the filler material includes, but is not limited to, polyamide (also known as Nylon), polycarbonate (PC), fiberglass (FG), polyethylene (PE), polyethylether (Polyether), polyethylene terephthalate (Polyethylene Glycol Terephthalate, PET), polymethyl methacrylate (Polymethyl Methacrylate, PMMA), polypropylene (Polypropylene), polystyrene (Polystyrene, PS), polyvinylchloride (Polyvinyl Chloride, PVC), and the like. Any one or a combination of any of the above materials may be used to form the present embodiments.
As shown in connection with fig. 1, 2 and 3, in some embodiments, at least one metal layer 11 is positioned on the non-display surface 102, and the escape window 1101 is positioned near at least one edge of the metal layer 11.
Through the arrangement, the at least one metal layer 11 of the display screen 1 is located on the non-display surface 102 of the display screen 1, so that the effects of increasing the structural strength and electromagnetic protection of the display screen 1 can be achieved, and the avoidance window 1101 corresponding to the NFC tag 2 is arranged on at least one edge of the metal layer 11, so that the influence of the avoidance gap on the structural strength of the display screen 1 can be reduced as much as possible compared with the case that the avoidance gap is located in the middle of the metal layer 11.

With the above arrangement, when the skin depth δ of the NFC tag 2 is greater than the thickness d of the trace layer 12, the electromagnetic wave of the NFC tag 2 can penetrate the trace layer 12, that is, the entire display screen 1.
Wherein skin depth delta refers to the distance at which the current density decreases exponentially with increasing depth from the conductor surface under alternating current or alternating electromagnetic field until 1/e (about 36.8%) of the surface current density is reached. The higher the frequency, the more pronounced the skin effect and the smaller the skin depth. For example, at low frequencies the current is distributed relatively uniformly over the conductor cross-section, while at high frequencies the current is concentrated mainly near the conductor surface.
When the skin depth delta is greater than the thickness d of the wiring layer 12, the alternating electromagnetic field generated by the NFC label 2 can penetrate from one side of the wiring layer 12 to the other side, so that transmission of electromagnetic waves is realized.
In some embodiments, the display screen 1 further includes a trace layer 12, where the magnetic permeability of the trace layer 12 is μ, the electrical conductivity is σ, the operating frequency of the NFC tag 2 is f, and the thickness of the trace layer 12 is d, which satisfies the following formula:
Where pi is the circumference ratio.
By the arrangement, the skin depth of the electromagnetic wave transmitted and received by the NFC tag 2 in the wiring layer 12 can be determined according to the magnetic conduction characteristic and the electric conduction characteristic of the wiring layer 12 and the working frequency of the NFC tag 2, and then the electromagnetic wave of the NFC tag 2 can be determined to transmit in the wiring layer 12.
In some embodiments, the display screen 1 further includes a trace layer 12, the magnetic permeability μ of the trace layer 12 is greater than or equal to 4pi× -7 H/M, the electrical conductivity σ is greater than or equal to 4000S/M, the operating frequency f of the NFC tag 2 is 13.56MHz, and the thickness d of the trace layer 12 is less than 0.068mm.
When the magnetic conductive property and the electric conductive property of the wiring layer 12 and the working frequency of the NFC tag 2 meet the above value range, transmission of electromagnetic waves of the NFC tag 2 in the wiring layer 12 can be realized, and the wiring layer 12 can meet the normal display requirement of the display screen 1, and the NFC tag 2 can meet the frequency requirement of NFC communication.
