Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the 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 by an embodiment of the present application is shown, and referring to fig. 2, a schematic diagram of a first radio frequency line and a second radio frequency line provided by an embodiment of the present application are shown and provided on an isolation layer. As shown in fig. 1 and 2, the display module includes: a substrate 10, a target coil 20 and an isolation layer 30.
The substrate 10, the target coil 20, and the spacer layer 30 are stacked in this order. The target coil 20 includes a first radio frequency coil 21 and a second radio frequency coil 22, the first radio frequency coil 21 and the second radio frequency coil 22 are both disposed on the isolation layer 30, 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, and the first radio frequency coil 21 and the second radio frequency coil 22 are disposed at least partially in parallel. The first end of the first radio frequency coil 21 is electrically connected to 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 to a power source. The isolation layer 30 is used for isolating radio frequency signals emitted 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 stacked in order, the target coil 20 includes the first rf coil 21 and the second rf coil 22, and thus, it is equivalent to disposing the first rf coil 21 and the second rf coil 22 directly between the substrate 10 and the isolation layer 30. Because 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, the first rf coil 21 and the second rf coil 22 are at least partially arranged in parallel, and the first end of the first rf coil 21 is electrically connected with the first end of the second rf coil 22, so that the first rf coil 21 and the second rf coil 22 form a closed coil, when power is supplied to the first rf coil 21 and the second rf coil 22, the first rf coil 21 and the second rf coil 22 can emit rf signals, and the first rf coil 21 and the second rf coil 22 can also avoid mutual interference, and the first rf coil 21 and the second rf coil 22 are mutually insulated, so that the function of emitting rf signals by the display module is realized. In addition, the isolation layer 30 can 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, thereby improving the performance of the display module for emitting radio frequency signals. That is, in the embodiment of the present application, by disposing the first rf coil 21 and the second rf coil 22 between the substrate 10 and the isolation layer 30, not only the display module has the function of transmitting rf signals, but also the thickness of the display module can be reduced without disposing other devices between the substrate 10 and the isolation layer 30, thereby reducing the thickness of the display module and further reducing the thickness of the electronic device.
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 manner, and the first rf coil 21 and the second rf coil 22 may be adhered to the substrate 10 by an adhesion manner, 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, the first rf coil 21 and the second rf coil 22 may be a plurality of bent-back-shaped arrangements. The first rf coil 21 and the second rf coil 22 may be nested with each other such that the first rf coil 21 and the second rf coil 22 are spaced apart from each other.
In addition, in the embodiment of the present application, the first rf coil 21 and the second rf coil 22 may be located in the same plane, so that the thickness of the target coil 20 is the thickness of the first rf coil 21 or the thickness of the second rf coil 22.
In addition, in the embodiment of the present application, the first rf coil 21 and the second rf coil 22 may transmit near field communication (Near Field Communication, NFC) signals, so that the display module has a near field communication 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 rf signals after being energized 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 conductive foam, the first rf coil 21 and the second rf coil 22 formed by the conductive foam not only can emit rf signals after being electrified, but also can play a role of buffering between the substrate 10 and the isolation layer 30.
In addition, in the related art, foam and a radio frequency coil are generally disposed between the substrate 10 and the isolation layer 30, the foam and the radio frequency coil are stacked, and the foam contacts the substrate 10, the radio frequency coil contacts the isolation layer 30, the foam plays a role in buffering between the substrate 10 and the isolation layer 30, and the radio frequency coil plays a role in transmitting radio frequency signals, but the thickness of the display module is large due to the arrangement.
In the embodiment of the application, the first rf coil 21 and the second rf coil 22 are made of conductive foam, so that the first rf coil 21 and the second rf coil 22 can have the function of transmitting rf signals, and can also have the buffering function and the supporting function between the substrate 10 and the isolation layer 30, that is, the first rf coil 21 and the second rf coil 22 made of conductive foam can replace foam and rf coils in related technologies, thereby reducing the thickness of the display module, making the thickness of the display module smaller, and further making the thickness of the electronic device using the display module smaller.
It should be noted that, when the first rf coil 21 and the second rf coil 22 are both conductive foam, the first rf coil 21 and the second rf coil 22 may be formed on a whole conductive foam by an etching process, and the first rf coil 21 and the second rf coil 22 are connected during etching.
In addition, in the embodiment of the present application, when the first rf coil 21 and the second rf coil 22 are both conductive foam, the first rf coil 21 and the second rf coil 22 may be bonded to the isolation layer 30 by bonding, where bonding glue may be used for bonding, and the bonding glue may be OCA optical glue. Of course, other bonding adhesives are also possible, and embodiments of the present application are not limited herein.
Additionally, in some embodiments, the first rf coil 21 and the second rf coil 22 may be a unitary structure.
When the first rf coil 21 and the second rf coil 22 are in an integral structure, the strength of the integral structure formed by the first rf coil 21 and the second rf coil 22 is high, so that the service lives of the first rf coil 21 and the second rf coil 22 are prolonged.
In addition, in some embodiments, the second end of the first rf coil 21 may be provided with a first conductive electrode 211, and the second end of the second rf 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 to connect to a power source.
When the second end of the first rf coil 21 is provided with the first conductive electrode 211 and the second end of the second rf coil 22 is provided with the second conductive electrode 221, at this time, when the first rf coil 21 and the second rf wire coil are required to be powered on, so that the first rf coil 21 and the second rf coil 22 emit rf wire signals, the first conductive electrode 211 and the second conductive electrode 221 can be connected with the power supply, so that the first rf coil 21 and the second rf coil 22 are powered on. That is, by providing the first conductive electrode 211 at the second end of the first rf coil 21 and providing the second conductive electrode 221 at the second end of the second rf coil 22, the first rf coil 21 and the second rf coil 22 can be conveniently energized, and thus the first rf coil 21 and the second rf coil 22 can be conveniently transmitting rf signals.
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 are not limited herein.
Additionally, in some embodiments, the display module may also include a flexible circuit board 40. The first conductive electrode 211 and the second conductive electrode 221 are 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, the flexible circuit board 40 is convenient to be connected with a power supply, so that power is conveniently supplied to the first rf coil 21 and the second rf coil 22 through the flexible circuit board 40, and the first rf coil 21 and the second rf coil generate rf line signals. That is, by providing the flexible circuit board 40, the first rf coil 21 and the second rf coil 22 can be conveniently energized, and the first rf coil 21 and the second rf coil 22 can be conveniently transmitting rf signals.
In addition, in some embodiments, the waterproof member 50 may be disposed at the connection of the first conductive electrode 211 and the flexible circuit, and at the connection of the second conductive electrode 221 and the flexible circuit board 40.
When the waterproof pieces 50 are arranged at the connection positions of the first conductive electrode 211 and the flexible circuit board 40 and the connection positions of the second conductive electrode 221 and the flexible circuit board 40, at this time, the problem of short circuit at the connection positions of the first conductive electrode 211 and the flexible circuit board 40 due to the action of water can be avoided through the waterproof pieces 50, and the problem of short circuit at the connection positions of the first conductive electrode 211 and the flexible circuit board 40 due to the action of water can be avoided, so that the power can be safely supplied when the power is supplied to the first radio frequency coil 21 and the second radio frequency coil 22.
It should be noted that, in the embodiment of the present application, the waterproof member 50 may be waterproof, that is, after the first conductive electrode 211 is connected to the flexible circuit board 40, the waterproof adhesive may be dispensed at 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 the action of water is avoided. Similarly, after the second conductive electrode 221 is connected to the flexible circuit board 40, a waterproof adhesive may be dispensed at the connection portion where the second conductive electrode 221 is connected to the flexible circuit board 40, so that the connection portion has waterproof performance, and the problem of short circuit at the connection portion due to the action of water is avoided.
Additionally, in some embodiments, the display module may further include an encapsulation layer 60. The encapsulation layer 60 is disposed on a first side of the substrate 10, the encapsulation layer 60 is used for encapsulating the substrate 10, the first rf coil 21 and the second rf coil 22 are disposed on a second side of the substrate 10, and the first side is opposite to the second side.
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 may prevent impurities from contacting the substrate 10, for example, water or oxygen may contact the substrate 10, so as to protect the substrate 10. That is, the encapsulation layer 60 can protect the substrate 10.
It should be noted that the material of the encapsulation layer 60 may be determined according to actual needs, and embodiments of the present application are not limited herein.
In addition, in some embodiments, the display module may further include a cover plate 70, where 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, and the first side is opposite to the second side.
When the display module includes the cover plate 70, and the cover plate 70 is disposed on the first side of the substrate 10, the cover plate 70 can protect the substrate 10 from being damaged due to other devices directly impinging on the substrate 10. That is, the cover plate 70 protects the substrate 10.
It should be noted that, the material of the cover plate 70 may be glass, but may be other materials, which is not limited herein.
In addition, in the embodiment of the present application, when the display module includes the encapsulation layer 60, at this time, the encapsulation layer 60 may be located between the cover plate 70 and the substrate 10, and the adhesive layer 71 is disposed between the encapsulation layer 60 and the cover plate 70, so that the cover plate 70 is adhered to the encapsulation layer 60 through the adhesive layer 71. The adhesive layer 71 may be an adhesive layer formed by OCA optical adhesive, however, the adhesive layer 71 may also be an adhesive layer formed by other adhesives, which is not limited herein.

The iron oxide includes ferric oxide, etc., and the other ingredients include nickel oxide, zinc oxide, manganese oxide, magnesium oxide, barium oxide, strontium oxide, etc. Of course, the material of the isolation layer 30 may be other materials with isolation signals, which is not limited herein.
In the embodiment of the present application, since the substrate 10, the target coil 20 and the isolation layer 30 are stacked in order, the target coil 20 includes the first rf coil 21 and the second rf coil 22, and thus, it is equivalent to disposing the first rf coil 21 and the second rf coil 22 directly between the substrate 10 and the isolation layer 30. Because 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, the first rf coil 21 and the second rf coil 22 are at least partially arranged in parallel, and the first end of the first rf coil 21 is electrically connected with the first end of the second rf coil 22, so that the first rf coil 21 and the second rf coil 22 form a closed coil, when power is supplied to the first rf coil 21 and the second rf coil 22, the first rf coil 21 and the second rf coil 22 can emit rf signals, and the first rf coil 21 and the second rf coil 22 can also avoid mutual interference, and the first rf coil 21 and the second rf coil 22 are mutually insulated, so that the function of emitting rf signals by the display module is realized. In addition, the isolation layer 30 can 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, thereby improving the performance of the display module for emitting radio frequency signals. That is, in the embodiment of the present application, by disposing the first rf coil 21 and the second rf coil 22 between the substrate 10 and the isolation layer 30, not only the display module has the function of transmitting rf signals, but also the thickness of the display module can be reduced without disposing other devices between the substrate 10 and the isolation layer 30, thereby reducing the thickness of the display module and further reducing the thickness of the electronic device.
The embodiment of the application provides electronic equipment, which comprises a power supply and a display module in any one of the embodiments. The power supply is electrically connected with the second end of the first radio frequency coil and the second end of the second radio frequency coil respectively.
