All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Referring to fig. 1, a schematic diagram of a display module provided in an embodiment of the present application is shown, and referring to fig. 2, a schematic diagram of a first rf line and a second rf line provided in an embodiment of the present application and disposed on an isolation layer is shown. As shown in fig. 1 and 2, the display module includes: a substrate 10, a target coil 20, and an isolation layer 30.

The target coil 20 includes a first rf coil 21 and a second rf coil 22, the first rf coil 21 and the second rf coil 22 are both disposed on the isolation layer 30, the first rf coil 21 and the second rf coil 22 are nested with each other, a gap exists between the first rf coil 21 and the second rf coil 22, and at least a portion of the first rf coil 21 and the second rf coil 22 are disposed in parallel. The first end of the first radio frequency coil 21 is electrically connected with the first end of the second radio frequency coil 22, and the second end of the first radio frequency coil 21 and the second end of the second radio frequency coil 22 are both used for connecting a power supply. The isolation layer 30 is used to isolate the radio frequency signals transmitted by the first radio frequency coil 21 and the second radio frequency coil 22.
In the embodiment of the present application, since the substrate 10, the target coil 20 and the isolation layer 30 are sequentially stacked, the target coil 20 includes the first rf coil 21 and the second rf coil 22, and thus it is equivalent to directly dispose the first rf coil 21 and the second rf coil 22 between the substrate 10 and the isolation layer 30. Because the first radio frequency coil 21 and the second radio frequency coil 22 are nested with each other, a gap exists between the first radio frequency coil 21 and the second radio frequency coil 22, at least part of the first radio frequency coil 21 and the second radio frequency coil 22 are arranged in parallel, and the first end of the first radio frequency coil 21 is electrically connected with the first end of the second radio frequency coil 22, therefore, the first radio frequency coil 21 and the second radio frequency coil 22 form a closed coil, so that when power is supplied to the first radio frequency coil 21 and the second radio frequency coil 22, the first radio frequency coil 21 and the second radio frequency coil 22 can transmit radio frequency signals, the first radio frequency coil 21 and the second radio frequency coil 22 can also avoid mutual interference, the first radio frequency coil 21 and the second radio frequency coil 22 are insulated from each other, and the function that the display module can transmit radio frequency signals is realized. In addition, the isolation layer 30 can also isolate the radio frequency signals emitted by the first radio frequency coil 21 and the second radio frequency coil 22, so that the radio frequency signals emitted by the first radio frequency coil 21 and the second radio frequency coil 22 cannot pass through the isolation layer 30 and can only be transmitted along the direction of the substrate 10, and further, the performance of the display module for emitting the radio frequency signals is improved. That is, in the embodiment of the present application, the first rf coil 21 and the second rf coil 22 are disposed between the substrate 10 and the isolation layer 30, so that the display module has a function of transmitting rf signals, and in addition, there is no need to dispose other devices between the substrate 10 and the isolation layer 30, and the thickness of the display module can be smaller, so as to reduce the thickness of the display module, and further make the thickness of the electronic device smaller.
It should be noted that the first rf coil 21 and the second rf coil 22 may be disposed on the isolation layer 30 by an adhesion method, and the first rf coil 21 and the second rf coil 22 may also be adhered to the substrate 10 by the adhesion method, so that the positions of the first rf coil 21 and the second rf coil 22 are fixed more firmly.
In addition, in the embodiment of the present application, as shown in fig. 2, each of the first rf coil 21 and the second rf coil 22 may be provided with a plurality of zigzag turns. The first radio frequency coil 21 and the second radio frequency coil 22 are nested with each other, and the first radio frequency coil 21 and the second radio frequency coil 22 are arranged at intervals.
In addition, in the embodiment of the present application, the first radio frequency coil 21 and the second radio frequency coil 22 may be located in the same plane, so that the thickness of the target coil 20 is the thickness of the first radio frequency coil 21 or the thickness of the second radio frequency coil 22.
In addition, in the embodiment of the present application, the first radio frequency coil 21 and the second radio frequency coil 22 may transmit Near Field Communication (NFC) signals, so that the display module has a NFC function.
In addition, in the embodiment of the present application, the principle that the first rf coil 21 and the second rf coil 22 can transmit the rf signal after being powered on is as follows: energizing the coil may generate an electromagnetic signal.
In addition, in some embodiments, the first rf coil 21 and the second rf coil 22 may be conductive foam.
When the first rf coil 21 and the second rf coil 22 are both made of conductive foam, the first rf coil 21 and the second rf coil 22 formed by the conductive foam can not only transmit rf signals after being powered on, but also play a role in buffering between the substrate 10 and the isolation layer 30.
In addition, in the related art, the foam and the rf coil are generally disposed between the substrate 10 and the isolation layer 30, the foam and the rf coil are stacked, the foam contacts the substrate 10, the rf coil contacts the isolation layer 30, the foam plays a role in buffering between the substrate 10 and the isolation layer 30, and the rf coil plays a role in transmitting rf signals, but the thickness of the display module is large due to the arrangement.
In the embodiment of the present application, the first radio frequency coil 21 and the second radio frequency coil 22 are made of the conductive foam, so that the first radio frequency coil 21 and the second radio frequency coil 22 can have a function of transmitting radio frequency signals, and can also have a buffering function and a supporting function between the substrate 10 and the isolation layer 30, that is, the first radio frequency coil 21 and the second radio frequency coil 22 made of the conductive foam can replace the foam and the radio frequency coil in the related art, so that the thickness of the display module can be reduced, the thickness of the display module is smaller, and the thickness of the electronic device using the display module is smaller.
It should be noted that, when the first rf coil 21 and the second rf coil 22 are both made of conductive foam, the first rf coil 21 and the second rf coil 22 may be formed on a whole piece of conductive foam through an etching process, and when etching, the first rf coil 21 and the second rf coil 22 are connected.
In addition, in the embodiment of the present application, when the first rf coil 21 and the second rf coil 22 are both made of conductive foam, at this time, the first rf coil 21 and the second rf coil 22 may be bonded to the isolation layer 30 in a bonding manner, wherein a bonding adhesive may be used for bonding, and the bonding adhesive may be OCA optical adhesive. Of course, other bonding glues may also be used, and the embodiments of the present application are not limited herein.
Additionally, in some embodiments, the first and second rf coils 21, 22 may be a unitary structure.
When the first rf coil 21 and the second rf coil 22 are of an integrated structure, the strength of the integrated structure formed by the first rf coil 21 and the second rf coil 22 is relatively high, so that the service life of the first rf coil 21 and the second rf coil 22 is prolonged.
In addition, in some embodiments, the second end of the first radio frequency coil 21 may be provided with a first conductive electrode 211, the second end of the second radio frequency coil 22 may be provided with a second conductive electrode 221, and both the first conductive electrode 211 and the second conductive electrode 221 are used for connecting a power supply.
When the first conductive electrode 211 is disposed at the second end of the first rf coil 21 and the second conductive electrode 221 is disposed at the second end of the second rf coil 22, at this time, when the first rf coil 21 and the second rf coil 22 need to be powered on, so that the first rf coil 21 and the second rf coil 22 transmit rf signals, the first conductive electrode 211 and the second conductive electrode 221 may be connected to the power supply, so as to power on the first rf coil 21 and the second rf coil 22. That is, by disposing the first conductive electrode 211 at the second end of the first rf coil 21 and disposing the second conductive electrode 221 at the second end of the second rf coil 22, it is convenient to energize the first rf coil 21 and the second rf coil 22, and thus to transmit rf signals by the first rf coil 21 and the second rf coil 22.
It should be noted that the first conductive electrode 211 and the second conductive electrode 221 may be pads, and of course, the first conductive electrode 211 and the second conductive electrode 221 may also be other devices, which is not limited herein.
In addition, in some embodiments, the display module may further include a flexible circuit board 40. The first conductive electrode 211 and the second conductive electrode 221 are both connected to the flexible circuit board 40, and the flexible circuit board 40 is used for connecting a power supply.
When the first conductive electrode 211 and the second conductive electrode 221 are both connected to the flexible circuit board 40, due to the property of the flexible circuit board 40, that is, the flexible circuit board 40 can be bent, and the shape of the flexible circuit board 40 is bent according to actual needs, so that the flexible circuit board 40 is conveniently connected to a power supply, and power is conveniently supplied to the first radio frequency coil 21 and the second radio frequency coil 22 through the flexible circuit board 40, so that the first radio frequency coil 21 and the second radio frequency coil generate radio frequency line signals. That is, the flexible circuit board 40 is disposed to facilitate the energization of the first rf coil 21 and the second rf coil 22, so as to facilitate the transmission of the rf signals by the first rf coil 21 and the second rf coil 22.
In addition, in some embodiments, the connection point of the first conductive electrode 211 and the flexible circuit and the connection point of the second conductive electrode 221 and the flexible circuit board 40 may be provided with the waterproof member 50.
When the connection position of the first conductive electrode 211 and the flexible circuit board 40 and the connection position of the second conductive electrode 221 and the flexible circuit board 40 are both provided with the waterproof piece 50, at this time, the problem of short circuit at the connection position of the first conductive electrode 211 and the flexible circuit board 40 due to the action of water can be avoided through the waterproof piece 50, and the problem of short circuit at the connection position of the first conductive electrode 211 and the flexible circuit board 40 due to the action of water can also be avoided, so that when the first radio frequency coil 21 and the second radio frequency coil 22 are supplied with power, the power can be supplied safely.
It should be noted that, in the embodiment of the present application, the waterproof member 50 may be made of waterproof glue, that is, after the first conductive electrode 211 is connected to the flexible circuit board 40, the waterproof glue may be applied to the connection position where the first conductive electrode 211 is connected to the flexible circuit board 40, so that the connection position has waterproof performance, and the problem of short circuit at the connection position due to water is avoided. Similarly, after the second conductive electrode 221 is connected to the flexible circuit board 40, the waterproof adhesive can be applied to the joint between the second conductive electrode 221 and the flexible circuit board 40, so that the joint has waterproof performance, and the problem of short circuit at the joint due to water is avoided.

When the encapsulation layer 60 is disposed on the first side of the substrate 10 and the encapsulation layer 60 encapsulates the substrate 10, the encapsulation layer 60 can prevent impurities from contacting the substrate 10, for example, water or oxygen contacts the substrate 10, and thus protects the substrate 10. That is, the encapsulation layer 60 may protect the substrate 10.
It should be noted that the material of the encapsulation layer 60 may be determined according to actual needs, and the embodiment of the present application is not limited herein.
In addition, in some embodiments, the display module further includes a cover plate 70, the cover plate 70 is disposed on a first side of the substrate 10, and the first rf coil 21 and the second rf coil 22 are disposed on a second side of the substrate 10, where the first side and the second side are opposite.

In the embodiment of the present application, since the substrate 10, the target coil 20 and the isolation layer 30 are sequentially stacked, the target coil 20 includes the first rf coil 21 and the second rf coil 22, and thus it is equivalent to directly dispose the first rf coil 21 and the second rf coil 22 between the substrate 10 and the isolation layer 30. Because the first radio frequency coil 21 and the second radio frequency coil 22 are nested with each other, a gap exists between the first radio frequency coil 21 and the second radio frequency coil 22, at least part of the first radio frequency coil 21 and the second radio frequency coil 22 are arranged in parallel, and the first end of the first radio frequency coil 21 is electrically connected with the first end of the second radio frequency coil 22, therefore, the first radio frequency coil 21 and the second radio frequency coil 22 form a closed coil, so that when power is supplied to the first radio frequency coil 21 and the second radio frequency coil 22, the first radio frequency coil 21 and the second radio frequency coil 22 can transmit radio frequency signals, the first radio frequency coil 21 and the second radio frequency coil 22 can also avoid mutual interference, the first radio frequency coil 21 and the second radio frequency coil 22 are insulated from each other, and the function that the display module can transmit radio frequency signals is realized. In addition, the isolation layer 30 can also isolate the radio frequency signals emitted by the first radio frequency coil 21 and the second radio frequency coil 22, so that the radio frequency signals emitted by the first radio frequency coil 21 and the second radio frequency coil 22 cannot pass through the isolation layer 30 and can only be transmitted along the direction of the substrate 10, and further, the performance of the display module for emitting the radio frequency signals is improved. That is, in the embodiment of the present application, the first rf coil 21 and the second rf coil 22 are disposed between the substrate 10 and the isolation layer 30, so that the display module has a function of transmitting rf signals, and in addition, there is no need to dispose other devices between the substrate 10 and the isolation layer 30, and the thickness of the display module can be smaller, so as to reduce the thickness of the display module, and further make the thickness of the electronic device smaller.
