In view of this, an embodiment of the present application provides a display device 100. The technical scheme provided by the embodiment of the application is suitable for electronic equipment with display functions such as televisions, players and industrial servers.

Referring to fig. 1 to 3, a display device 100 includes a housing 10 and an antenna 20. The case 10 may be understood as a protection structure or an internal component covering structure of the display device 100 for protecting the internal components from damage by the external environment. While the housing 10 also serves to provide structural support and decoration.

The antenna 20 is used to receive or transmit communication signals. The antenna 20 may be provided inside the housing 10 or may be provided outside the housing 10. In practical applications, a metal component (such as a heat sink) is present inside the housing 10, and the metal component may shield and interfere with the signal of the antenna 20, so the antenna 20 may be mounted at a position that is considered to avoid the metal component. In addition, in order to facilitate receiving and transmitting signals, the antenna 20 may be located near a signal input/output interface of the display, such as HDMI, DP, etc. Thus, the path length of signal transmission can be reduced, and the signal transmission efficiency can be improved.

The antenna 20 is adhered to the housing 10 by a foam 60. The foam rubber 60 is adhesive, and the foam rubber 60 is also called sponge rubber.

The antenna 20 has an adhesive surface adhered to the housing 10, and a first side 211 and a second side 212 connected to the adhesive surface and disposed opposite to each other, and the foam 60 is disposed between the adhesive surface and the housing 10 and covers at least a portion of the first side 211 and a portion of the second side 212.

Wherein the adhesive surface faces the housing 10 and the foam 60 is arranged between the adhesive surface and the housing 10. And the foam gel 60 covers at least a portion of the first side 211 and a portion of the second side 212.

It is understood that the foam gel 60 may cover a portion of the first side 211, or a portion of the second side 212, or may cover the first side 211 and the second side 212 entirely.

In this embodiment, the foam 60 has not only the function of connecting the antenna 20 with the housing 10, but also the function of structurally reinforcing the first side 211 and the second side 212. By disposing the foam 60 between the adhesive surface and the case 10 and covering at least a part of the first side 211 and a part of the second side 212, the structure of the first side 211 and the second side 212 can be reinforced, and the antenna 20 is not easily damaged, so that the stability of communication signal transmission can be improved.

In addition, in the case that the antenna 20 is detached, the foam 60, part of which is not detached from the first side 211 and the second side 212, can play a role of buffering, reducing the risk of damage to the antenna 20. In some embodiments, the antenna 20 further has a third side 213 and a fourth side 214 connected to and disposed opposite to the bonding surface, the first side 211 and the second side 212. The foam 60 also covers at least a portion of the third side 213 and the fourth side 214. It is understood that the foam gel 60 may completely cover the third side 213 and the fourth side 214.

The structural strength of the third side 213 and the fourth side 214 can be enhanced by covering at least a portion of the third side 213 and a portion of the fourth side 214 with the foam 60, thereby further reinforcing the circumference of the antenna 20.

In some embodiments, the foam gel 60 covering the first side 211, the second side 212, the third side 213, and the fourth side 214 is disposed in series. In other words, a portion of the adhesive 60 is located between the adhesive surface and the housing 10, and another portion of the adhesive 60 extends one turn around the circumference of the antenna 20 without interruption. In this way, the foam 60 can be firmly provided around the periphery of the antenna 20, and reinforce the periphery of the antenna 20.

In some embodiments, at least one of the first side 211, the second side 212, the third side 213, and the fourth side 214 is provided with a groove 215, and the foam gel 60 fills the groove 215. Illustratively, as depicted in fig. 2, the first side 211 is provided with a groove 215, and the second side 212, the third side 213, and the fourth side 214 are not provided with grooves 215.

In this embodiment, at least one of the first side 211, the second side 212, the third side 213 and the fourth side 214 is provided with a groove 215, the surface area of the side provided with the groove 215 is increased, the contact area with the foam gel 60 is increased, the connection stability between the antenna 20 and the housing 10 can be improved, and the risk of the antenna 20 falling off from the housing 10 can be reduced.

In some embodiments, the foam 60 wraps around the antenna 20 to form a hug for the antenna 20, greatly improving the structural strength around the antenna 20.

In some embodiments, the housing 10 has an inner sidewall to which the antenna 20 is bonded. So that the antenna 20 can be accommodated in the housing 10.

In some embodiments, the display device 100 may include a panel 12, the housing 10 may include a middle frame 13 and a back plate 11, the panel 12 is disposed opposite the back plate 11, the middle frame 13 connects the panel 12 with the back plate 11, and the antenna 20 is adhered to a surface of the back plate 11 facing the panel 12. There is typically some space available between the back plate 11 and the internal structure. This space allows for easy installation of the antenna 20 without affecting the compact design of the other components.

In addition, in a crowded interior space of the display device 100, the FPC antenna placed at the back plate is less shielded. For example, in the display device 100, the multilayer structure such as the liquid crystal display layer and the polarizer may attenuate and reflect signals to some extent, and the back plate 11 is positioned on the back surface and is not blocked by these components, so that signals from the rear and side directions can be received more effectively.

In some embodiments, antenna 20 includes a housing 21 and a circuit board 22 disposed within housing 21. A housing 21. It is understood that the bonding surface, the first side 211, the second side 212, the third side 213, and the fourth side 214 are wall surfaces of the housing. The housing may also include a heat dissipating surface 216, the heat dissipating surface 216 being disposed opposite the bonding surface. The first side 211, the second side 212, the third side 213, and the fourth side 214 are all connected to the bonding surface and are all connected to the heat dissipating surface 216.

Referring to fig. 3, in some embodiments, the circuit board 22 is an FPC board. In the present embodiment, the antenna 20 can be understood as the FPC antenna 20. The FPC board has a thin thickness, which is advantageous in reducing the volume of the antenna 20. The FPC board is flexible, can adapt to complicated shell shape or complex environment, and communication stability performance is higher.

The FPC board includes a substrate 221 and a conductive pattern 222 disposed on the substrate 221.

Alternatively, the substrate 221 is a flexible board prepared from a material having a small high frequency loss. The material of the substrate 221 may include, but is not limited to, polyimide, liquid crystal polymer, and the like.

The conductive pattern 222 is a line set according to a desired frequency band so that a desired frequency can be received or transmitted. The conductive pattern 222 is made of a material having good conductivity and characteristics suitable for a flexible substrate. Alternatively, the conductive pattern 222 is formed of conductive ink or a metal material through preparation.

For example, screen printing may be used to form the conductive pattern 222. Screen printing refers to making a designed circuit pattern into a screen plate, wherein pattern parts on the screen plate are transparent, and non-pattern parts are closed. The conductive ink is then printed through the mesh of the stencil onto the substrate 221, and dried and cured to form conductive traces.

In some embodiments, the thickness of the foam 60 disposed between the bonding surface and the housing 10 ranges between 0.2mm and 0.4 mm. The foam gel 60 disposed between the bonding surface and the housing 10 is suitable in material amount, has high bonding strength, and has a small amount.

Illustratively, the thickness of the foam 60 disposed between the bonding surface and the housing 10 may be 0.2mm, 0.23mm, 0.25mm, 0.3mm, 0.33mm, 0.35mm, 0.37mm, 0.4mm, and any number therebetween.

In some embodiments, the housing 21 further has a heat dissipating surface 216 disposed opposite to the bonding surface, and the display device 100 further includes a heat dissipating member 30, where the heat dissipating member 30 is thermally coupled to the heat dissipating surface 216, and the heat dissipating member 30 is capable of dissipating heat from the antenna 20, so as to mitigate the risk of performance and lifetime degradation of the antenna 20 due to temperature increase. In the FPC antenna 20, the FPC board is highly integrated and has poor heat dissipation, and therefore the heat sink 30 is particularly suitable for the FPC antenna 20.

Optionally, the heat dissipation element 30 is made of silica gel, and the silica gel covers the heat dissipation surface 216. The silica gel has higher heat conductivity coefficient, is favorable for conducting the heat of the antenna 20 to the shell 10 so as to dissipate, and improves the heat dissipation efficiency of the antenna 20.

Referring to fig. 4, in some embodiments, display device 100 further includes control board 40 and wires 50. Control board 40 may be a logic board responsible for signal, image, sound, or fault handling. Control board 40 is electrically connected to circuit board 22 by first conductors 50. The housing 21 is provided with a through hole (not shown in the figure) through which the wire 50 passes. The conductive pattern 222 has a first pad 223 and a second pad 224, and the first pad 223 is spaced apart from the second pad 224 to avoid a short circuit between the first pad 223 and the second pad 224. The first welding point 223 and the second welding point 224 are welded to the same end of the wire 50, so that the wire 50 has two connection points with the first welding point 223 and the second welding point 224, and in the case that one of the first welding point 223 and the second welding point 224 fails in welding, the other can be kept connected with the wire 50, and the connection reliability is higher.

In order to facilitate the welding of the first welding spot 223 and the second welding spot 224 to the same end of the wire 50, the first welding spot 223 and the second welding spot may be disposed close to each other in case that the first welding spot 223 and the second welding spot are disposed at a distance that is not short-circuited.

The foregoing has outlined rather broadly the more detailed description of embodiments of the application, wherein the principles and embodiments of the application are explained in detail using specific examples, the above examples being provided solely to facilitate the understanding of the method and core concepts of the application; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in light of the ideas of the present application, the present description should not be construed as limiting the present application.
