Description

Technical Field

[0001] This utility model relates to the field of display technology, specifically to a highly transparent, flexible and bendable LED crystal film screen. Background Technology

[0002] In the field of display technology, the technical architecture of traditional LED displays (such as LED curtain wall screens and advertising screens) has long relied on rigid substrates, metal circuits, and heavy packaging processes, resulting in the following core pain points in practical applications:

[0003] 1) Rigid structure limits scene adaptation: Traditional LED screens are supported by PCB rigid boards or metal frames, and the minimum bending radius is usually greater than 50cm. They cannot achieve seamless bonding to curved, spherical and other irregular surfaces, which poses obvious installation obstacles in scenarios such as curved glass curtain walls in smart buildings and curved screens for vehicle central control.

[0004] 2) Complex installation: Traditional LED screens are generally thicker than 10mm, requiring steel structure brackets or embedded mounting frames, which makes the installation process complex (requiring welding, drilling, etc.). The installation cost accounts for 30%-40% of the overall project cost, and disassembly can easily damage the building surface.

[0005] 3) Low light transmittance affects scene integration: The light transmittance of traditional LED screens is generally less than 30%, which will seriously block natural light when used in glass curtain walls, requiring additional indoor lighting equipment and increasing building energy consumption by about 20%. At the same time, the non-transparent structure destroys the overall appearance of the building and makes it difficult to meet the aesthetic requirements of high-end commercial spaces for "screen-wall integration".

[0006] In conclusion, the market currently lacks display products that combine thinness, high light transmittance, and strong environmental adaptability, and a new display technology is urgently needed to break through existing bottlenecks. Utility Model Content

[0007] In order to overcome the problems of high rigidity, complex installation and low light transmittance of existing LED screens, this utility model provides a highly transparent, flexible and bendable LED crystal film screen.

[0008] The technical solution of this utility model is as follows:

[0009] A highly transparent, flexible, and bendable LED crystal film screen includes an LED crystal film screen module and a power supply box disposed on one side of the LED crystal film screen module. The LED crystal film screen module includes an upper transparent protective film, a vacuum sealant, a lamp board, and a lower transparent protective film arranged sequentially. The lamp board is a transparent crystal film film with a transparent mesh circuit etched on its surface. Multiple arrayed LED beads are mounted on the surface of the transparent mesh circuit. The transparent mesh circuit is electrically connected to the LED beads and the power supply box, respectively.

[0035] Please see Figures 1 to 4This utility model provides a highly transparent, flexible, and bendable LED crystal film screen, including an LED crystal film screen module 1 and a power supply box 2 disposed on one side of the LED crystal film screen module 1. The LED crystal film screen module 1 includes an upper transparent protective film 11, a vacuum sealant 12, a lamp board 13, and a lower transparent protective film 14 arranged sequentially. The lamp board 13 is a transparent crystal film film, and a transparent mesh circuit 15 is etched on its crystal film surface. The surface of the transparent mesh circuit 15 uses bare die bonding technology to mount multiple arrayed LED beads 16 with micron-level precision. The transparent mesh circuit 15 is electrically connected to the LED beads 16 and the power supply box 2 respectively. Among them, the LED beads 16 use bare die bonding technology to mount on the surface of the transparent mesh circuit 15 (i.e., the crystal film surface) with micron-level precision, achieving ultra-thin packaging (<0.5mm) and significantly reducing the weight of the screen. Vacuum sealing 12 is formed by resin sealing in a vacuum environment, ensuring that the components are dustproof and waterproof (IP68 rating) while maintaining high light transmittance and flexibility. Transparent mesh circuit 15 uses an etching process to form a high-precision circuit on the surface of the crystal film, which has both conductivity and light transmittance, avoiding the light-blocking problem of traditional metal circuits.

[0036] This embodiment of the LED crystal film screen uses bare crystal ball planting technology to directly mount LED beads 16 onto the transparent mesh circuit 15 of the transparent crystal film film, combined with vacuum sealing 12 for protection. This achieves a thin and light-reducing display (thickness <2mm), high light transmittance (95%), and strong environmental adaptability, breaking the rigid limitations of traditional LED screens. It meets the urgent needs of smart buildings, commercial windows, vehicle displays, and other scenarios for transparent display and flexible installation, promoting the development of display technology towards high-end and green technologies. With a light transmittance of 95%, it can perfectly integrate with the building glass curtain wall 3 without obstructing natural light. It supports curved, spherical, and other irregular shapes for installation, with a bending radius as low as 10cm, making its application scenarios highly expandable. No steel structure support is required; simply peel off the lower transparent protective film 14 to directly mount it onto the glass curtain wall 3 or the wall surface. Figure 2 As shown, this greatly improves installation efficiency and reduces installation costs; under the protection of vacuum sealing 12, the weather resistance of components is improved, greatly extending their service life.

[0037] Please see Figure 5, in one embodiment, a power supply 21 and a control circuit board 22 are provided inside the power supply box 2. The control circuit board 22 is electrically connected to the power supply 21 and the transparent mesh circuit 15 respectively. A power supply terminal 23 is provided on the control circuit board 22, and a power supply opening corresponding to the power supply terminal 23 is provided on the power supply box 2. In this embodiment, by integrating the power supply 21 and the control circuit board 22 inside the power supply box 2 to form an independent control module, the connection structure between the screen body and the outside is simplified, the clutter problem of traditional decentralized wiring is avoided, and the system compactness is improved; the power supply terminal 23 is exposed through the power supply opening, supporting quick plug-and-play wiring (such as AC 220V input), and the strong power connection can be completed without professional tools, reducing the installation threshold and shortening the construction time.

[0038] Please refer to Figure 3 , Figure 5 , in one embodiment, the control circuit board 22 is electrically connected to the transparent mesh circuit 15 through a module wiring port 24. Specifically, a module wiring head 17 is provided on one side of the transparent mesh circuit 15, and a module wiring port 24 matching the module wiring head 17 is provided on the control circuit board 22. The settings of the module wiring head 17 and the module wiring port 24 achieve the electrical connection between the control circuit board 22 and the transparent mesh circuit 15, and make the connection between the two more stable and reliable. In addition, a wiring opening 25 for inserting the module wiring head 17 is provided at the bottom of one end of the power supply box 2 close to the transparent mesh circuit 15. The module wiring head 17 of the transparent mesh circuit 15 is inserted into the wiring opening 25, making the installation and maintenance of the power supply box 2 and the LED crystal film screen module 1 more convenient.

[0039] Please refer to Figure 5 , in one embodiment, a receiving card 26 is provided on the control circuit board 22. As the core component of the display control system, the receiving card 26 is responsible for receiving external signals (such as HDMI, USB) and converting them into driving signals for the LED lamp beads 16. Preferably, the receiving card 26 is an R5S receiving card. The R5S receiving card supports 4K resolution input, with a refresh rate of up to 1920Hz, meeting the requirements for high-definition dynamic picture display; it supports mainstream control protocols (such as SPI, CAN), is compatible with multiple signal sources (computers, mobile devices, sensors), and can be seamlessly connected to the intelligent building management system (BMS) or the vehicle central control system to achieve linkage control; it supports cascading expansion, and a single receiving card 26 can drive multiple LED crystal film screen modules 1, suitable for large-area curtain wall splicing scenarios, reducing the number of control nodes and the system complexity.

[0040] Please refer to Figure 5In one embodiment, the control circuit board 22 is provided with a plurality of signal interfaces 27, and the power supply box 2 is provided with a plurality of signal openings corresponding to the signal interfaces 27. Preferably, the signal interface 27 is an RJ45 interface. The RJ45 interface supports Ethernet communication (TCP / IP protocol), can be directly connected to a local area network, and realizes remote control (such as updating advertising content in real time through a cloud platform), meeting the needs of multi-store cluster management in new retail scenarios.
