[0001] This application relates to the field of display technology, and more specifically to a display device. Background Technology

[0002] A display device is a device that converts electronic signals into visual images. Display devices are widely used in various electronic devices such as televisions, media players, and industrial servers. The antenna is one of the core components of a display device; it is mainly used for receiving and transmitting communication signals. Taking a television as an example, the antenna can receive wireless signals, such as Wi-Fi or Bluetooth signals, enabling the television to wirelessly connect to the network or other devices.

[0003] In related technologies, the miniaturization of antennas results in lower structural strength, making them susceptible to damage from vibration, which in turn leads to unstable communication signal transmission. Utility Model Content

The foam adhesive is disposed between the adhesive surface and the housing, and at least covers a portion of the first side surface and a portion of the second side surface.

[0006] In some embodiments, the antenna further has a third side and a fourth side that are connected to and opposite to the adhesive surface, the first side and the second side, and the foam adhesive further covers at least a portion of the third side and a portion of the fourth side.

[0007] In some embodiments, the foam adhesive covering the first side, the second side, the third side, and the fourth side is continuously disposed.

Detailed Implementation

[0024] The following embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0026] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] In the description of the embodiments of this application, the term "or" is merely a description of the relationship between related objects, indicating that two relationships can exist, which can represent: A existing alone, or B existing alone.

[0029] In the description of the embodiments of the present application, the term "multiple" refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).

[0030] In display devices, the miniaturization of antennas results in lower structural strength, making them susceptible to damage from vibration, which in turn leads to unstable communication signal transmission. This is especially true for FPC antennas, which use plastic housings. While plastic housings contribute to weight reduction, they also have lower strength and are easily damaged by vibration, leading to the exposure of the internal FPC board or the entry of foreign objects (such as dust) into the antenna, resulting in unstable communication signal transmission.

[0031] Therefore, this application provides a display device 100. The technical solution provided by this application is applicable to electronic devices with display functions, such as televisions, media players, and industrial servers.

[0032] Reference Figures 1 to 3 The display device 100 includes a housing 10 and an antenna 20. The housing 10 can be understood as a protective structure or an internal component covering structure of the display device 100, which is used to protect the internal components and prevent damage to the internal components from the external environment. At the same time, the housing 10 also serves to provide structural support and decoration.

[0033] Antenna 20 is used to receive or transmit communication signals. Antenna 20 can be installed inside or outside the housing 10. In practical applications, the housing 10 contains metal components (such as heat sinks), which can shield and interfere with the signal from antenna 20. Therefore, the installation location of antenna 20 should be considered to avoid metal components. Furthermore, to facilitate signal reception and transmission, antenna 20 can be placed close to the display's signal input / output interfaces, such as HDMI or DP interfaces. This reduces the signal transmission path length and improves signal transmission efficiency.

[0034] The antenna 20 is bonded to the housing 10 using foam adhesive 60. Foam adhesive 60 is an adhesive, also known as sponge rubber.

[0035] The antenna 20 has an adhesive surface that is bonded to the housing 10, and a first side 211 and a second side 212 that are connected to and opposite to the adhesive surface. Foam adhesive 60 is disposed between the adhesive surface and the housing 10, and at least covers a portion of the first side 211 and a portion of the second side 212.

[0036] The adhesive surface faces the outer shell 10, and the foam adhesive 60 is disposed between the adhesive surface and the outer shell 10. Furthermore, the foam adhesive 60 at least covers a portion of the first side 211 and a portion of the second side 212.

[0037] It is understandable that the foam adhesive 60 can cover a part of the first side 211, or a part of the second side 212, or completely cover both the first side 211 and the second side 212.

[0038] In this embodiment, the foam adhesive 60 not only connects the antenna 20 to the housing 10, but also strengthens the structure of the first side 211 and the second side 212. By placing the foam adhesive 60 between the bonding surface and the housing 10, and at least covering part of the first side 211 and part of the second side 212, the structure of the first side 211 and the second side 212 can be strengthened, the antenna 20 is less prone to damage, and thus the stability of communication signal transmission can be improved.

[0039] Furthermore, in the event of antenna 20 detachment, the portion of foam adhesive 60 that remains attached to the first side 211 and the second side 212 can act as a buffer, reducing the risk of damage to antenna 20. In some embodiments, antenna 20 further has a third side 213 and a fourth side 214 that are connected to and opposite to the adhesive surface, the first side 211, and the second side 212. Foam adhesive 60 also at least partially covers the third side 213 and the fourth side 214. Understandably, foam adhesive 60 can completely cover the third side 213 and the fourth side 214.

[0040] By covering at least part of the third side 213 and part of the fourth side 214 with foam adhesive 60, the structural strength of the third side 213 and the fourth side 214 can be improved, thereby further strengthening the area around the antenna 20.

[0041] In some embodiments, the foam adhesive 60 covering the first side 211, the second side 212, the third side 213, and the fourth side 214 is continuously disposed. In other words, a portion of the foam adhesive 60 is located between the adhesive surface and the outer casing 10, and another portion of the foam adhesive 60 extends uninterruptedly around the circumference of the antenna 20. This arrangement allows the foam adhesive 60 to firmly surround the antenna 20, reinforcing the area around the antenna 20.

[0042] 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 adhesive 60 fills the groove 215. For example, as... Figure 2 The first side 211 is provided with a groove 215, while the second side 212, the third side 213 and the fourth side 214 are not provided with grooves 215.

[0043] 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 with the groove 215 is increased, and its contact area with the foam adhesive 60 is increased, which can improve the connection stability between the antenna 20 and the outer shell 10 and reduce the risk of the antenna 20 falling off the outer shell 10.

[0044] In some embodiments, the foam adhesive 60 wraps around the antenna 20, forming a tight embrace of the antenna 20 and greatly improving the structural strength around the antenna 20.

[0045] In some embodiments, the housing 10 has an inner sidewall to which the antenna 20 is adhered. Thus, the antenna 20 can be accommodated within the housing 10.

[0046] In some embodiments, the display device 100 may include a panel 12, and the housing 10 may include a mid-frame 13 and a back plate 11. The panel 12 and the back plate 11 are disposed opposite to each other, and the mid-frame 13 connects the panel 12 and the back plate 11. The antenna 20 is bonded to the surface of the back plate 11 facing the panel 12. There is usually a certain space available between the back plate 11 and the internal structure. This space allows for convenient installation of the antenna 20 without affecting the compact design of other components.

[0047] Furthermore, in the cramped internal space of the display device 100, the FPC antenna placed on the back panel is less obstructed. For example, in the display device 100, the multi-layer structure such as the liquid crystal display layer and polarizer will cause some signal attenuation and reflection, while the back panel 11 is located on the back and is not obstructed by these components, thus enabling it to receive signals from the rear and sides more effectively.

[0048] In some embodiments, the antenna 20 includes a housing 21 and a circuit board 22 disposed within the housing 21. The housing 21 includes an adhesive surface, a first side surface 211, a second side surface 212, a third side surface 213, and a fourth side surface 214, which are the walls of the housing. The housing may also include a heat dissipation surface 216, which is disposed opposite to the adhesive surface. The first side surface 211, the second side surface 212, the third side surface 213, and the fourth side surface 214 are all connected to the adhesive surface and to the heat dissipation surface 216.

[0049] Reference Figure 3 In some embodiments, circuit board 22 is an FPC board. In this embodiment, antenna 20 can be understood as FPC antenna 20. The thinner FPC board helps reduce the size of antenna 20. The FPC board is flexible and can adapt to complex shell shapes or complex environments, resulting in higher communication stability.

[0050] The FPC board includes a substrate 221 and a conductive pattern 222 disposed on the substrate 221.

[0051] Optionally, the substrate 221 is a flexible board made of a material with low high-frequency loss. The material of the substrate 221 may include, but is not limited to, polyimide, liquid crystal polymer, etc.

[0052] The conductive pattern 222 is a circuit arranged according to the desired frequency band, thereby enabling the reception or transmission of the required frequency. The conductive pattern 222 is made of a material with good conductivity and adaptability to flexible substrates. Optionally, the conductive pattern 222 is formed by preparing conductive ink or a metallic material.

[0053] Taking conductive ink as an example, screen printing can be used to create the conductive pattern 222. Screen printing refers to creating a screen stencil of the designed circuit pattern, where the patterned areas are transparent and the non-patterned areas are closed. Then, the conductive ink is printed onto the substrate 221 through the mesh of the screen stencil. After drying and curing, a conductive circuit is formed.

[0054] In some embodiments, the thickness of the foam adhesive 60 disposed between the bonding surface and the housing 10 ranges from 0.2 mm to 0.4 mm. This configuration results in an appropriate amount of foam adhesive 60 material between the bonding surface and the housing 10, achieving high bonding strength with minimal material usage.

[0055] For example, the thickness of the foam adhesive 60 disposed between the adhesive surface and the housing 10 can be 0.2 mm, 0.23 mm, 0.25 mm, 0.3 mm, 0.33 mm, 0.35 mm, 0.37 mm, 0.4 mm and any value between these.

[0056] In some embodiments, the housing 21 further has a heat dissipation surface 216 disposed opposite to the bonding surface, and the display device 100 further includes a heat sink 30, which is thermally coupled to the heat dissipation surface 216. The heat sink 30 can dissipate heat for the antenna 20, mitigating the risk of performance and lifespan degradation of the antenna 20 due to temperature increases. In the FPC antenna 20, the FPC board has high integration and poor heat dissipation; therefore, the heat sink 30 is particularly suitable for the FPC antenna 20.

[0057] Optionally, the heat sink 30 is made of silicone, and the silicone covers the heat dissipation surface 216. Silicone has a high thermal conductivity, which helps to conduct the heat of the antenna 20 to the outer casing 10 for dissipation, thereby improving the heat dissipation efficiency of the antenna 20.

[0058] Reference Figure 4In some embodiments, the display device 100 further includes a control board 40 and wires 50. The control board 40 may be a logic board responsible for signal, image, sound, or fault processing. The control board 40 is electrically connected to the circuit board 22 via a first wire 50. The housing 21 is provided with a through hole (not shown) for the wires 50 to pass through. The conductive pattern 222 has a first solder joint 223 and a second solder joint 224, which are spaced apart to avoid short circuits between the first solder joint 223 and the second solder joint 224. The first solder joint 223 and the second solder joint 224 are soldered to the same end of the wires 50, so that the wires 50 have two connection points with the first solder joint 223 and the second solder joint 224. If one of the first solder joint 223 and the second solder joint 224 fails, the other can remain connected to the wires 50, resulting in higher connection reliability.

[0059] To facilitate the welding of the first solder point 223 and the second solder point 224 to the same end of the conductor 50, the first solder point 223 and the second solder point can be placed close to each other, provided that the spacing between the first solder point 223 and the second solder point does not cause a short circuit.

[0060] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
