Description

Technical Field

[0001] This utility model relates to a flexible LED folding screen. Background Technology

[0002] Flexible LED foldable screens are a new type of display device based on bendable substrate technology. They achieve repeated folding by integrating micro-LED units onto flexible circuits. Their core advantages lie in their lightweight portability and adaptability, making them widely applicable in wearable devices, portable display terminals, and curved advertising devices.

[0003] Traditional flexible screens are prone to circuit breakage and LED unit detachment when repeatedly folded; the lack of precise positioning in the folding mechanism leads to uneven creases on the screen; insufficient heat dissipation causes localized overheating; and complex cable connections are required when splicing multiple screens, affecting expansion efficiency and aesthetics. In addition, the surface protective layer has weak impact resistance and is easily damaged by bumps and knocks in mobile scenarios. Utility Model Content

[0004] The purpose of this invention is to provide a flexible LED folding screen to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flexible LED folding screen includes a flexible substrate, LED units, signal lines, connecting terminals, magnetic interfaces, and a protective layer. Multiple LED units are equidistantly welded to the front side of the flexible substrate. The signal lines are embedded in the flexible substrate and welded to the LED units. The connecting terminals are fixedly connected to the upper right side of the flexible substrate. The magnetic interfaces are fixedly connected to the outside of the connecting terminals. The protective layer is fixedly connected to the front side of the flexible substrate.

[0007] Based on the above technical solution, the back side of the flexible substrate includes a hinge shaft, a positioning groove, an elastic rubber connector, a flexible buckle, and anti-bending reinforcing ribs. The hinge shaft is installed at the center of the back side of the flexible substrate, the positioning groove is opened on both sides of the hinge shaft, the elastic rubber connector is fixedly connected between the hinge shaft and the inside of the positioning groove, the flexible buckle is fixedly connected to both sides inside the positioning groove, and multiple anti-bending reinforcing ribs are equidistantly embedded inside the flexible substrate.

[0008] Based on the above technical solution, the protective layer includes a wear-resistant coating, a buffer air cushion layer, and a copper foil heat sink. The wear-resistant coating is distributed on the outside of the buffer air cushion layer, and the copper foil heat sink is fixedly connected to the inside of the buffer air cushion layer.

[0009] Compared with the prior art, this utility model has the following advantages: This utility model significantly improves the overall performance through triple innovative design: First, it adopts a synergistic buffer structure of chain shaft and elastic rubber connector, combined with the mechanical positioning design of flexible buckle locking positioning groove, which effectively eliminates folding stress and ensures the uniformity of creases, while the anti-bending reinforcing rib inhibits substrate deformation; Second, it achieves multi-functional protection through three-layer composite protective layer; the wear-resistant coating resists surface wear, the buffer cushion layer absorbs external impact, and the built-in copper foil heat sink efficiently dissipates the heat of the LED unit; In addition, the integrated design of magnetic interface and connection terminal realizes non-destructive adsorption connection between screens, greatly improving the efficiency of multi-screen splicing.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1-3 As shown, a flexible LED folding screen includes a flexible substrate 1, LED units 2, signal lines 3, connection terminals 4, magnetic interfaces 5, and a protective layer 6. Multiple LED units 2 are equidistantly welded to the front side of the flexible substrate 1. The signal lines 3 are embedded in the flexible substrate 1 and welded to the LED units 2. The connection terminals 4 are fixedly connected to the upper right side of the flexible substrate 1. The magnetic interfaces 5 are fixedly connected to the outside of the connection terminals 4. The protective layer 6 is fixedly connected to the front side of the flexible substrate 1.

[0016] The back of the flexible substrate 1 includes a hinge shaft 7, a positioning groove 8, an elastic rubber connector 9, a flexible buckle 10, and anti-bending reinforcing ribs 11. The hinge shaft 7 is installed at the center of the back of the flexible substrate 1. The positioning groove 8 is formed on both sides of the hinge shaft 7. The elastic rubber connector 9 is fixedly connected between the hinge shaft 7 and the inside of the positioning groove 8. The flexible buckle 10 is fixedly connected to both sides inside the positioning groove 8. Multiple anti-bending reinforcing ribs 11 are equidistantly embedded inside the flexible substrate 1.

[0017] The protective layer 6 includes a wear-resistant coating 12, a cushioning air cushion layer 13, and a copper foil heat sink 14. The wear-resistant coating 12 is distributed on the outside of the cushioning air cushion layer 13, and the copper foil heat sink 14 is fixedly connected to the inside of the cushioning air cushion layer 13.

[0018] The working principle of this utility model is as follows: When the screen is folded, the hinge shaft 7 acts as a rotation fulcrum to guide the bending trajectory. At this time, the elastic rubber connector 9 compresses and stores energy to buffer stress, while the flexible buckle 10 is embedded in the positioning groove 8 to lock the folding angle. In the unfolded state, the anti-bending reinforcing rib 11 maintains the flatness of the flexible substrate 1. During the display process, the signal lines 3 embedded in the substrate transmit driving signals to the equidistantly distributed LED units 2 to achieve image display. For protection, external impacts are first dispersed and absorbed by the buffer air cushion layer 13, while the heat generated by the LEDs is dissipated laterally through the copper foil heat sink 14. At the same time, the wear-resistant coating 12 continuously resists surface friction damage. When multi-screen expansion is performed, the magnetic interface 5 automatically adsorbs and aligns and connects the connection terminal 4, thereby achieving instantaneous and seamless transmission of power and signals.

[0019] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
