Description

Technical Field

[0001] This utility model relates to the field of flexible transparent antenna technology, and in particular to a flexible transparent antenna for curved display devices. Background Technology

[0002] With the rapid development of smart terminal devices, curved display technology has been widely used in smartphones, wearable devices, automotive displays, and smart home applications due to its superior visual immersion, high space utilization, and aesthetically pleasing design. Wireless communication functions (such as 5G, Wi-Fi, Bluetooth, and NFC) have become standard features in these devices, thus placing higher demands on the performance of built-in antennas.

[0003] However, traditional metal antennas are mostly rigid structures, making it difficult to adapt to the shape requirements of curved or flexible display panels. Furthermore, their opacity severely impacts the display effect and aesthetics of the screen, limiting their application in high-end display devices. To address these issues, flexible transparent antennas have emerged. These antennas, possessing excellent radio frequency performance, high light transmittance, and superior flexibility, can be seamlessly integrated into the interior or surface of curved or flexible displays, making them considered an ideal solution. However, existing flexible transparent antennas still face numerous challenges in actual installation and use. Due to the varying degrees of curvature in curved screens, the antenna module is prone to edge lifting and poor adhesion during attachment due to uneven stress distribution, leading to bubbles, delamination, and even structural damage. This not only increases installation difficulty but also directly reduces antenna signal stability and shortens product lifespan.

[0004] Therefore, there is a need for a flexible, transparent antenna that is easy to install for curved display devices. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, where curved screens have varying degrees of curvature, antenna modules are prone to edge lifting and poor adhesion during the attachment process due to uneven stress distribution. This can lead to air bubbles, delamination, and even structural damage, which not only increases installation difficulty but also directly causes a decrease in antenna signal stability and shortens product lifespan. The purpose of this utility model is to provide a flexible transparent antenna for curved display devices that is easy to install.

[0006] The technical solution is as follows: A flexible transparent antenna for curved display devices includes a flexible transparent substrate, a transparent conductive radiator, a transparent dielectric layer, and a transparent grounding layer. The transparent conductive radiator is disposed on the top of the flexible transparent substrate, the transparent dielectric layer is disposed on the top of the transparent conductive radiator, and the transparent grounding layer is disposed on the top of the transparent dielectric layer. It also includes a polyimide mounting shell, a transparent adhesive layer, a fixing seat, guide rods, a limiting plate, and an elastic element. The polyimide mounting shell is disposed on the outside of the flexible transparent substrate. Multiple transparent adhesive layers are disposed on the bottom of the polyimide mounting shell. A fixing seat is fixedly connected to the right side of the polyimide mounting shell. Two guide rods are slidably disposed on the fixing seat. The two guide rods are fixedly connected to the limiting plate. The limiting plate is in contact with the flexible transparent substrate. An elastic element is sleeved on the guide rods. The two ends of the elastic element are respectively connected to the fixing seat and the limiting plate.

[0007] As an improvement to the above solution, it also includes a mounting base, metal connecting plates, pressure plates, connectors, and wires. The mounting base is provided at the bottom right side of the transparent conductive radiator. Two metal connecting plates are connected to the right side of the transparent conductive radiator. The pressure plate is covered on the top of the mounting base and is in close contact with the metal connecting plates.

[0010] As an improvement to the above solution, a notch groove is provided on the left side of the polyimide mounting shell.

[0011] As an improvement to the above solution, an ultra-thin dustproof film is provided on top of the transparent grounding layer.

[0012] Compared with the prior art, this utility model provides a flexible transparent antenna for curved display devices, which has the following advantages: 1.

This installation method is simple and quick, and improves the installation efficiency.

Detailed Implementation

[0024] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning.

[0025] Example 1: A flexible transparent antenna for curved display devices, please refer to... Figure 1 , Figure 2 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 The system includes a flexible transparent substrate 1, a transparent conductive radiator 2, a transparent dielectric layer 3, and a transparent grounding layer 4. The transparent conductive radiator 2 is located on top of the flexible transparent substrate 1. The transparent conductive radiator 2 is made of indium tin oxide (ITO), silver nanowires, graphene, or conductive polymer materials, possessing the dual advantages of high conductivity and high light transmittance. The transparent dielectric layer 3 is located on top of the transparent conductive radiator 2, and the transparent grounding layer 4 is located on top of the transparent dielectric layer 3. The system also includes a polyimide mounting shell 5, a transparent adhesive layer 501, a fixing base 6, a guide rod 7, a limiting plate 8, and an elastic element 9. The polyimide mounting shell 5 is located on the outer side of the flexible transparent substrate 1. The polyimide material has high strength, high temperature resistance, and good flexibility, effectively protecting the internal structure. The bottom of the polyimide mounting shell 5... The device is equipped with three transparent adhesive layers 501. A fixing seat 6 is fixedly connected to the right side of the polyimide mounting shell 5. Two guide rods 7 are slidably mounted on the fixing seat 6. The two guide rods 7 are fixedly connected to a limiting plate 8. The limiting plate 8 is in contact with the flexible transparent substrate 1. An elastic element 9 is sleeved on the guide rod 7. The two ends of the elastic element 9 are connected to the fixing seat 6 and the limiting plate 8, respectively. A notch 18 is opened on the left side of the polyimide mounting shell 5. When the antenna needs to be repaired, the notch 18 increases the force application point, making it easier to remove the antenna module composed of the flexible transparent substrate 1, transparent conductive radiator 2, transparent dielectric layer 3 and transparent grounding layer 4. An ultra-thin dustproof film is provided on the top of the transparent grounding layer 4. The ultra-thin dustproof film is made of hydrophobic transparent material to prevent dust adhesion and improve the surface scratch resistance.

[0026] Before installing the flexible transparent antenna, first push the limiting plate 8 to the right to compress the elastic element 9. Then, place the pre-assembled antenna module (composed of a flexible transparent substrate 1, a transparent conductive radiator 2, a transparent dielectric layer 3, and a transparent grounding layer 4 laminated together) into the polyimide mounting shell 5. After placement, release the limiting plate 8. Under the restoring force of the elastic element 9, the limiting plate 8 moves to the left and continuously presses against the right edge of the antenna module. This structure provides an adaptive clamping force when the antenna is attached to a curved surface, ensuring that each layer of the antenna module fits tightly against the curved surface, effectively preventing detachment or signal performance degradation due to warping or stress rebound. Finally, the antenna module is fully inserted through the bottom of the polyimide mounting shell 5. The gelatin layer 501 firmly bonds the entire device to the surface of the curved display device without affecting the display effect. This installation method is simple and quick, improving installation efficiency. During operation, the transparent conductive radiator 2 serves as the core functional layer of the antenna, responsible for the radiation and reception of electromagnetic waves. It is attached to the flexible transparent substrate 1 and has good bending performance and high light transmittance. The transparent conductive radiator 2 is covered with a transparent dielectric layer 3 (such as transparent epoxy resin or acrylic material) and a transparent ground layer 4 in sequence, which together form a standard microstrip antenna structure. Among them, the transparent dielectric layer 3 mainly plays the role of electrical isolation and impedance matching, while the transparent ground layer 4 can significantly improve the radiation efficiency and directivity of the antenna.

[0027] Example 2: Based on Example 1, please refer to... Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 It also includes a mounting base 10, metal connecting pieces 11, a pressure plate 1101, a connector 12, and a wire 13. The mounting base 10 is located at the bottom right side of the transparent conductive radiator 2. Two metal connecting pieces 11 are connected to the right side of the transparent conductive radiator 2. The pressure plate 1101 is covered on the top of the mounting base 10 and is in close contact with the metal connecting pieces 11. The connector 12 is connected to the right side of the metal connecting pieces 11, and the wire 13 is connected to the right end of the connector 12. Elastic buckles 14 are fixedly connected to both the front and rear sides of the pressure plate 1101. Card seats 15 are fixedly connected to both the front and rear sides of the mounting base 10. Card seats 15 have slots 16, and the elastic buckles 14 engage with the slots 16. Two rubber strips 17 are provided inside the mounting base 10. The rubber strips 17 are in close contact with the pressure plate 1101, which provides a comprehensive effect of preventing loosening, damping, and sealing, thereby ensuring the reliability of the connection.

[0028] In terms of signal connection, one end of the metal connecting piece 11 is electrically connected to the transparent conductive radiator 2, and the other end leads out the wire 13 through the connector 12 to achieve connection with the motherboard RF interface. The connection between the metal connecting piece 11 and the transparent conductive radiator 2 is supported by the mounting base 10, and the pressure plate 1101 covers it. The two work together to press the metal connecting piece 11 and the connector 12 tightly to ensure the stability and low impedance of the electrical connection. The pressure plate 1101 is engaged with the card slot 15 on the mounting base 10 through the elastic buckle 14 to achieve quick assembly and reliable locking.
