In the display module disclosed in the embodiment of the present application, the NFC coil 110 is disposed on the cover plate 210, and the NFC coil 110 is located in the insulating layer 220, so that the NFC coil 110 effectively utilizes the inner space of the insulating layer 220, the thickness of the display module is not additionally increased, the display module is light and thin, and the electronic device using the display module is light and thin. Meanwhile, the thickness of the display module is reduced without forming a groove for accommodating the NFC coil 110 on the cover plate 210, so that the structural stability and integrity of the cover plate 210 are ensured, and the difficulty of the processing technology of the cover plate 210 is reduced. The NFC ferrite 120 is disposed on a side of the cover plate 210 facing away from the insulating layer 220, and the NFC ferrite 120 is spaced apart from the NFC coil 110, so as to ensure a sufficient approach communication distance therebetween.
Optionally, when the NFC coil 110 is arranged, the NFC coil 110 may be deposited on the surface of the cover plate 210 on the side away from the display direction of the display screen 200, and then the insulating layer 220 is deposited on the surface of the cover plate 210 on the side away from the display direction of the display screen, so that the insulating layer 220 covers the NFC coil 110, and the process difficulty of the display module is further reduced.
In order to form a complete display screen 200 structure, the display screen main body comprises a polarization layer 230 and a substrate layer 240, the cover plate 210, the insulating layer 220, the polarization layer 230 and the substrate layer 240 are sequentially stacked in the thickness direction of the four layers, the cover plate 210 can play a role of protecting the display module, the polarization layer 230 plays a role of polarization, and the insulating layer 220 and the polarization layer 230 can be connected through a light-transmitting connecting glue 231. Substrate layer 240 is a basic component of display panel 200, substrate layer 240 can carry various components for mounting display panel 200, such as polarizing layer 230, insulating layer 220 and cover plate 210 described above, and substrate layer 240 is carried on substrate layer 240, and typically, substrate layer 240 may be a glass substrate, so that it can transmit light. The substrate layer 240 typically includes a lower glass layer and an upper glass layer that are stacked. Alternatively, the light-transmissive connection paste 231 may be an OCA paste layer.
Optionally, the NFC coil 110 may also be disposed on two opposite sides of the polarizing layer 230 in the thickness direction or two opposite sides of the substrate layer 240 in the thickness direction, specifically, when the NFC coil 110 is disposed on the polarizing layer 230, it may be disposed on one side of the polarizing layer 230 opposite to the display direction of the display screen 200 or one side of the polarizing layer 230 facing the display direction of the display screen 200, and accordingly, the insulating layer 220 should also be disposed on one side of the polarizing layer 230 opposite to the display direction of the display screen 200 or one side of the polarizing layer 220 facing the display direction of the display screen 200, and the insulating layer 220 also plays a role of protecting the NFC coil 110. 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 towards the display direction of the display screen 200, and accordingly, the insulating layer 220 is selectively disposed on a side of the substrate layer 240 facing away from the display direction of the display screen 200 or facing towards the display direction of the display screen 200 according to a specific position of the NFC coil 110, and the insulating layer 220 should also cover the NFC coil 110.

Accordingly, the display area 200a has a corresponding projection position on the cover 210, which is a display projection, and the non-display area 200b also has a corresponding projection position on the cover 210, which is a non-display projection, which is also to be disposed around the display projection.
In order to make the sensing performance of the NFC module 100 stronger, the NFC coil 110 may be configured in multiple turns, and in order to reduce the influence of the NFC coil 110 on the display effect of the display screen 200, the multiple-turn NFC coil 110 should extend at the edge of the display screen 200, specifically, a part of the NFC coil 110 is located in the non-display area 200b of the display screen 200, and corresponds to the non-display projection area on the cover plate 210, and another part of the NFC coil 110 is located in the display area 200a of the display screen 200, and is located at a position where the display area 200a is close to the non-display area 200b, and corresponds to a position where the display projection is close to the non-display projection on the cover plate 210, so that the influence of the NFC coil 110 on the display effect of the display screen 200 is reduced while the NFC coil 110 is configured in multiple turns. Meanwhile, the screen flash problem caused by the NFC coil 110 being too close to the center of the display screen 200 can also be alleviated.
It should be noted that, in order to ensure that the thickness of the display module is not additionally increased on the premise that the inductive performance of the NFC coil 110 is excellent, each turn of the NFC coil 110 with multiple turns should be arranged on the same layer, so as to avoid the NFC coil 110 from being stacked.
Optionally, because part of the NFC coil 110 enters the display area 200a of the display screen 200, in order to reduce the influence of the part of the NFC coil 110 on the display effect of the display area 200a, the NFC coil 110 may adopt transparent routing, and the NFC coil 110 of the transparent routing does not influence the display image of the display area 200a, thereby being beneficial to improving the screen occupation ratio of the display screen 200. Specifically, the NFC coil 110 of the transparent trace may be made of indium tin oxide, TiAlTi, or nano silver, and when indium tin oxide and TiAlTi are used as the NFC coil 110, the NFC coil 110 is usually deposited on the cover plate 210 in a magnetron sputtering manner, and when nano silver is used as the NFC coil 110, the NFC coil 110 is usually deposited on the cover plate 210 in a solution coating method.

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 apart from the edge of the display screen 200, so that the first coil end 111 can be electrically connected to one end of the flexible electrical connector 300 through the bridging trace 400. When the NFC coil 110 is disposed in multiple turns, the bridging trace 400 crosses over a portion of the NFC coil 110, and in order to avoid short circuit caused by direct contact between the bridging trace 400 and a portion of the NFC coil 110, an insulating material may be coated on the surface of the bridging trace 400. As the number of turns of the NFC coil 110 increases, the edge distance between the first coil end 111 and the display screen 200 increases, and correspondingly, the length of the bridging trace 400 should also increase, and the application is not limited to the specific number of turns of the NFC coil 110 and the length of the bridging trace 400. Alternatively, the flexible electrical connector 300 may be a flexible circuit board.
Optionally, the display panel 200 further includes a protective layer 250, and the protective layer 250 is stacked on a side of the insulating layer 220 facing away from the cover plate 210.

Specifically, the protection layer 250 may be an organic photoresist type encapsulation glass.
It should be noted that, after the bridge trace 400 is led out from the first coil end 111 of the NFC coil 110, the first portion of the bridge trace 400 located in the insulating layer 220 should be configured not to contact with the NFC coil 110, and specifically, the insulating layer 220 is located between the first portion and the NFC coil 110 to prevent the bridge trace 400 and the NFC coil 110 from contacting and short-circuiting.
