[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0024] Figure 1 This is a schematic diagram of the digital display structure provided in this embodiment. Figure 2 This is a schematic cross-sectional view of the assembled digital display structure provided in the embodiment.

[0025] like Figure 1 , Figure 2 As shown, the digital display structure includes at least an LED display substrate 10, a support layer 20, a scattering layer 30, and a diffusion film 40, which are stacked and bonded together in sequence. The LED display substrate 10 is placed at the bottom layer and is used to provide a light source and display a pattern. The LED display substrate 10 is embedded in the support layer 20, and the scattering layer 30 is bonded above the support layer 20. The support layer 20 separates the LED display substrate 10 and the scattering layer 30, forming a hollow cavity between the LED display substrate 10 and the scattering layer 30. The scattering layer 30 is used to scatter the light source of the LED display substrate 10. Scattering particles are added to the scattering layer 30, and the scattering layer 30 provides a scattering cloud for the light source of the LED display substrate 10. The diffusion film 40 is bonded above the scattering layer 30.

[0026] Specifically, such as Figure 1 As shown, the LED display substrate 10 includes an LED module 11 and a printed circuit board 12, with the LED module 11 disposed on the printed circuit board 12. One side of the LED display substrate 10 having the LED module 11 is embedded in the support layer 20.

[0027] The LED module 11 includes a first LED module 111 located at the center of the printed circuit board 12 and a second LED module 112 located around the first LED module 111. In this embodiment, the first LED module 111 is circular in shape, and the second LED module 112 is annular in shape surrounding the first LED module 111. The first LED module 111 is mainly used to provide LED light source for the display pattern at the center of the digital display structure, and the area of ​​the first LED module 111 is set according to the actual usage requirements. The second LED module 112 is mainly used to provide LED light source for the periphery of the display pattern of the digital display structure, so as to achieve a centrifugal scattering effect around the circle.

[0028] Specifically, the light source of the first LED module 111 located at the center is mainly white monochromatic light, or it can be defined as red (R), green (G), and blue (B) multicolor light. By customizing the ratio of red (R), green (G), and blue (B) components, any color can be achieved, providing countless possible colors of light for the central display pattern of the digital display structure. The light source of the second LED module 112, located in a ring around the first LED module 111, is mainly red (R), green (G), and blue (B) multicolor visible light. By customizing the ratio of red (R), green (G), and blue (B) components, any color can be achieved, providing countless possible colors of light for the ring-shaped display pattern of the digital display structure. The LEDs of the second LED module 112 are evenly arranged in a ring shape around the first LED module 111.

[0029] In this embodiment, the printed circuit board 12 is mainly made of common materials such as FR4, CEM3, and CEM1, and provides pads and driving lines for the first LED module 111 and the second LED module 112. FR4 is a glass fiber reinforced epoxy resin substrate; CEM3 is an organic glass fiber reinforcing material composed of glass fiber and epoxy resin; and CEM1 is a single-sided glass fiber board.

[0030] like Figure 1 and Figure 2As shown, in this embodiment, the center of the support layer 20 is a circular hollow structure 21, the area of ​​which is the same as the area of ​​the first LED module 111. The first LED module 111 is embedded in the center of the circular hollow structure 21. The outer periphery of the hollow structure of the support layer 20 is a circular hollow structure 22, and the second LED module 112 is embedded in the circular hollow structure 22. Furthermore, the circular hollow structure 21 and the circular hollow structure 22 are separated by a partition wall 23, which completely isolates the light sources of the first LED module 111 and the second LED module 112. That is, the width of the outer circular hollow structure 22 of the support layer 20 is the same as the width of the ring of the second LED module 112. The partition wall 23 and the outer frame structure of the support layer 20 completely embed the second LED module 112, preventing light leakage from the second LED module 112.

[0031] The support layer 20 provides an annular cavity and a central cavity for the scattering layer 30, and the annular cavity and central cavity of the support layer 20 isolate the light sources of the first LED module 111 and the second LED module 112 on the surface of the LED display substrate 10. Furthermore, a connecting strip is provided between the circular hollow structure 21 and the annular hollow structure 22 of the support layer 20, thereby stabilizing the structures of the circular hollow structure 21 and the annular hollow structure 22. The isolation wall 23 separates the light sources of the first LED module 111 and the second LED module 112, but does not affect the propagation of the light sources of the first LED module 111 and the second LED module 112 within their respective areas. The bottom layer of the support layer 20 is fixed to the printed circuit board 12 of the LED display substrate 10, and the top layer of the support layer 20 is bonded and fixed to the scattering layer 30. The material of the support layer 20 is mainly engineering plastics such as PC, ABS, PC+ABS, and PPO.

[0032] In this embodiment, the scattering layer 30 is annular and is attached to the annular hollow structure 22 of the support layer 20. The scattering layer 30 is located above the second LED module 112 and scatters the light source of the second LED module 112. The scattering layer 30 forms hollow cavities between the first LED module 111 and the second LED module 112 through the support layer 20, and the light sources of the first LED module 111 and the second LED module 112 propagate between their respective hollow cavities.

[0033] The scattering layer 30 is located between the diffusion film 40 and the support layer 20. The scattering layer 30 is embedded in the top of the support layer 20 and is flush with the top of the support layer 20. The diffusion film 40 is attached to the scattering layer 30 and the support layer 20. In this embodiment, the substrate of the scattering layer 30 is one or more of epoxy resin, polycarbonate, polymethyl methacrylate, or acrylonitrile-butadiene-styrene plastic. The scattering layer 30 is doped with scattering particles, which provide a scattering cloud for the light source of the LED module 11 and are positioned above the LED light source of the LED module 11, providing a sufficiently scattering interface for the diffusion film 40. The scattering particles are incorporated into the scattering layer 30 through processes such as dispensing, mold injection, and mold molding.

[0034] In this embodiment, the diffusion film 40 is a gradient color diffusion film 40, and the material of the diffusion film 40 is a plastic film such as polycarbonate or PET; the center of the diffusion film 40 is a circular printed display pattern, and the content displayed at the center (such as a fan) is defined by color ink printing or printing; the outermost ring of the diffusion film 40 is a gradient gray-white layered circle. The outermost ring of the diffusion film 40 forms a layered, gradient gray-white layered circle.

[0035] This application provides a digital display structure that separates an LED display substrate 10 and a scattering layer 30 through a support layer 20, and forms a hollow cavity between the LED display substrate 10 and the scattering layer 30. Scattering particles are added within the scattering layer 30, and the scattering layer 30 provides a scattering cloud layer to the light source of the LED display substrate 10. A scattering depth is provided before the light source of the LED display substrate 10 reaches the scattering layer 30, making the light-emitting surface uniform. Then, combined with a diffusion film 40, a scattering ring effect is achieved. The digital display structure provided in this application, through structural design, allows for strong plasticity in the scattering area. Utilizing a gradual transition effect and configuring a certain sequence of running lights, a centrifugal scattering effect around a circle is achieved, enabling dynamic content display.
