The NFC ferrite 120 is disposed on a side of the polarizing layer 220 facing away from the insulating layer 230, and the NFC ferrite 120 has a certain distance from the NFC coil 110, so as to ensure a sufficient near field communication distance between the two.

In order to form a complete display screen 200 structure, a substrate layer 240 is stacked on one side of the polarizing layer 220, which is opposite to the insulating layer 230, and the cover plate 210, the insulating layer 230, the polarizing layer 220 and the substrate layer 240 are sequentially stacked along the thickness directions of the four layers, wherein the cover plate 210 can play a role in protecting a display module, the polarizing layer 220 plays a role in polarizing, and the cover plate 210 and the insulating layer 230 can be connected through a light-transmitting connection adhesive 211. The substrate layer 240 is a basic component of the display screen 200, and the substrate layer 240 is capable of carrying and mounting various components of the display screen 200, such as the polarizing layer 220, the insulating layer 230, and the cover plate 210 described above, are carried on the substrate layer 240, and typically, the substrate layer 240 may be a glass substrate, so that it is capable of transmitting light.

When the NFC coil 110 is disposed on the substrate layer 240, it may be disposed on a side of the substrate layer 240 facing away from the display direction of the display screen 200, or disposed on a side of the substrate layer 240 facing toward the display direction of the display screen 200, and accordingly, the insulating layer 230 is selectively disposed on a side of the substrate layer 240 facing away from the display direction of the display screen 200 or a side facing toward the display direction of the display screen 200 according to a specific position of the NFC coil 110, and the insulating layer 230 should also cover the NFC coil 110.

At the same time, the problem of screen flicker of the display screen 200 caused by too close of the NFC coil 110 to the center of the display screen 200 can be alleviated
It should be noted that, in order to not increase the thickness of the display module additionally on the premise of ensuring good induction performance of the NFC coil 110, each turn of the NFC coil 110 in a multi-turn arrangement should be arranged in the same layer, so as to avoid stacking of the NFC coils 110.

Optionally, the NFC coil 110 includes a first coil end 111 adjacent to the center of the display screen 200 and a second coil end 112 adjacent to the edge of the display screen 200, so that a certain distance is provided between the first coil end 111 and the second coil end 112, and when the NFC coil 110 is disposed in multiple circles, the distance is further increased. Specifically, the second coil end 112 of the NFC coil 110 is adjacent to the edge of the display screen 200, so that it can be directly electrically connected to one end of the flexible electrical connector 300, while the first coil end 111 of the NFC coil 110 is spaced from the edge of the display screen 200, so that the first coil end 111 is electrically connected to one end of the flexible electrical connector 300 through the bridging wire 400.

As the number of turns of the NFC coil 110 increases, the distance between the first coil end 111 and the edge of the display screen 200 increases, and accordingly, the length of the bridging wire 400 should also increase, and the specific number of turns of the NFC coil 110 and the length of the bridging wire 400 are not limited in this application.
Optionally, the display screen 200 further includes a protective layer 250, where the protective layer 250 is stacked on a side of the insulating layer 230 facing away from the polarizing layer 220. After the bridging wire 400 is led out from the second coil end 112 of the NFC coil 110, the bridging wire 400 passes through the insulating layer 230, and since the protective layer 250 is stacked on the insulating layer 230, the first portion of the bridging wire 400 is located in the insulating layer 230, and the second portion of the bridging wire 400 is located in the protective layer 250, the protective layer 250 wraps the insulating layer 230 and the bridging wire 400, and the protective layer 250 can serve to encapsulate the insulating layer 230 and the bridging wire 400, prevent moisture and oxygen from corroding the NFC coil 110 and the bridging wire 400, and protect the NFC coil 110 and the bridging wire 400. Specifically, the protective layer 250 may be an encapsulation glass such as an organic photoresist.
It should be noted that, after the bridging wire 400 is led out from the first coil end 111 of the NFC coil 110, the first portion thereof located in the insulating layer 230 should be disposed not to contact the NFC coil 110, and in particular, the insulating layer 230 is located between the first portion and the NFC coil 110 to separate the NFC coil 110 from the first portion of the bridging wire 400 so as to prevent the bridging wire 400 from contacting the NFC coil 110 and shorting.
Optionally, one end of the polarizing layer 220 has an end outer edge 220a, the insulating layer 230 forms a first projection on the polarizing layer 220, the end outer edge 220a forms a second projection on the polarizing layer 220, the first projection and the second projection are coplanar, and the first projection is located on one side of the second projection, so that the end outer edge 220a is a portion of an end edge of the polarizing layer 220 extending toward a side far from a center of the polarizing layer 220, and the insulating layer 230 is not stacked on the end outer edge 220 a.

The connection adhesive 600 is more beneficial to fixing the flexible electric connector 300, so that the connection between the flexible electric connector 300 and the first electrode plate 220b and the second electrode plate 220c is more stable, and meanwhile, the connection adhesive 600 can prevent the end of the flexible electric connector 300 from bending at a larger angle, thereby playing a role in protecting the flexible electric connector 300.
Specifically, the first coil end 111 of the NFC coil 110 is connected to the first electrode pad 220b through the bridging trace 400, so that an end of the bridging trace 400 away from the first coil end 111 extends to the end outer edge 220a, the second coil end 112 of the NFC coil 110 is connected to the second electrode pad 220c, and the flexible electrical connector 300 is simultaneously connected to the first electrode pad 220b and the second electrode pad 220c, so that the first electrode pad 220b and the second electrode pad 220c should be disposed close to each other, so that the flexible electrical connector 300 is connected to both at the same time, and accordingly, a distance between the first coil end 111 and the second coil end 112 should not be too large, specifically, a distance between projections of the first coil end 111 and the second coil end 112 on a plane perpendicular to the display screen 200 should be set to be smaller, so that a length of the bridging trace 400 can be reduced, and performance stability of the display module disclosed in the embodiments of the present application is better.
