[0035] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0036] Example

[0037] Depend on Figure 1As shown, this embodiment provides a boneless transparent ultra-thin LED display screen with integrated lamp and driver. The display screen is spliced ​​by multiple LED display screen modules 1. Each LED display screen module 1 includes a transparent glass PCB substrate 11 (thickness 0.5 mm), and at least one packaging body 12 is arranged on one side of the substrate.

[0038] In this embodiment, a magnet is provided at the bottom of the package body 12, which corresponds to the magnetic attraction structure (not shown in the figure) on the upper surface of the PCB substrate 11. The package body 12 is fixed to the PCB substrate 11 by magnetic adsorption, while ensuring electrical connection. When disassembling, only opposite force needs to be applied.

[0039] The specific structure of the package body 12 is as follows: a driver IC 121 and at least one LED lamp bead 123 are integrated inside the package body 12, and a lamp driver package cover 122 is wrapped around the driver IC 121 and the at least one LED lamp bead 123. The LED lamp bead 123 includes an LED chip and a chip package cover wrapped around its light-emitting body. The chip package cover adopts a transparent epoxy resin package cover with a thickness of 0.8 mm to ensure transparency and ultra-thin characteristics. The welding part of the LED chip realizes precise electrical connection with the driver IC 121 through micro solder balls. The diameter of the solder balls is less than 0.2 mm, which ensures efficient current conduction and ultra-thin package design.

[0040] In this embodiment, a lens-shaped reflective structure is arranged around the light-emitting body of the LED chip inside the package 12 to enhance the light utilization and display effect of the LED lamp bead 123. At the same time, phosphor is coated on the surface of the light-emitting body to improve color saturation and consistency.

[0041] The inner and outer surfaces of the package body 12 are specially treated: the inner surface is coated with an antistatic isolation coating to prevent static electricity from damaging the LED chip; the outer surface is coated with a transparent conductive coating, which not only enhances the antistatic ability but also plays an electromagnetic shielding role.

[0042] The dot spacing between two adjacent LED lamp beads 123 is set to 15 mm, ensuring a good display effect and sufficient transparency. At the edge of the LED display screen module 1, a buckle assembly is used for locking connection to ensure the stability and convenience of the connection between the modules.

[0043] A layer of transparent adhesive is applied to the side of the PCB substrate 11 away from the package body 12 so that it can be easily attached to a transparent or translucent mounting surface. At the same time, in order to protect the surface of the display screen, a layer of acrylic transparent protective mask 13 is also attached to the surface of the entire display screen to enhance the wear resistance and scratch resistance of the display screen.

[0044] In practical applications, the size and shape of the display screen can be easily adjusted by quickly disassembling the LED display screen module 1 as needed to meet the needs of different scenarios. In addition, the connection method using the magnetic absorption layer 14 is also feasible. It only needs to apply the magnetic absorption layer 14 on the edge of the module, and the adjacent modules can be automatically adsorbed and locked by magnetic force, which improves the convenience of installation and disassembly.

[0045] The embodiment of the utility model provides a light-driven integrated boneless transparent ultra-thin LED display screen, which has the advantages of significantly simplified structure and easy maintenance compared with the prior art due to the modular design, integrated light-driven packaging and detachable connection technology. By using a magnetic layer 14 or a snap-on assembly connection at the edge of the LED display screen module 1, not only is the display screen easy to assemble and flexible to disassemble, but the size of the display screen can also be freely changed according to actual needs, thereby meeting a variety of scene applications.

[0046] The package body 12 integrates the driver IC 121 and the LED lamp bead 123, and uses the solder ball technology to achieve precise connection. The chip package cover with a reflective structure (such as a lens or a reflective cup) on the inner surface effectively improves the light effect and display quality. The package cover is made of transparent epoxy resin or silicone material to ensure ultra-thin and transparent characteristics. At the same time, by setting an antistatic isolation coating on the inner surface and coating the outer surface with a metal grid or a transparent conductive coating, the antistatic ability and conductive performance of the product are enhanced.

[0047] The dot spacing between the LED lamp beads 123 is reasonably designed, and the PCB substrate 11 is made of transparent glass, plastic or film, which not only ensures the transparency of the display screen, but also ensures the overall ultra-thin design. In addition, by adhering a transparent or translucent adhesive or magnetic material to the back of the PCB substrate 11, the display screen can be easily attached to various surfaces, further reflecting its boneless film screen characteristics.

[0048] Finally, an acrylic transparent protective mask 13 is added to the surface of the display screen, which improves the durability and protection level of the display screen and ensures stable operation in various environments.

[0049] To sum up, the integrated lamp-driven boneless transparent ultra-thin LED display provided in this embodiment has made outstanding contributions in terms of simplified structure, convenient maintenance, flexible splicing and improved display performance, successfully solved many technical problems existing in traditional LED display screens, and realized a new round of innovation and upgrading of display screen technology.
