DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0035] In order to reduce the damage to human eyes caused by blue light emitted by the display module in life, the present invention provides an LED display module and an LED display device. Figure 1 to Figure 1And specific embodiments are provided to explain the LED display module and the LED display device in detail.

[0036] The LED display module 100 includes: a substrate 10, a plurality of LED lamp beads 20, a solid glue layer 30, a light shielding layer 40 and a filter structure 50. The LED lamp beads 20 have a light-emitting area 21 and a plastic bracket 22 that wraps the light-emitting area 21. The plurality of LED lamp beads 20 are arranged on the substrate 10 and arranged in an array; the solid glue layer 30 is arranged on the substrate 10 and wraps each of the LED lamp beads 20; the light shielding layer 40 has a plurality of openings 41, the light shielding layer 40 is arranged on the solid glue layer 30, the openings 41 of the light shielding layer 40 correspond to the light-emitting areas 21 of the LED lamp beads 20 one by one, and the openings 41 of the light shielding layer 40 expose the light-emitting areas 21 of each of the LED lamp beads 20; the filter structure 50 is arranged on the solid glue layer 30, and the filter structure 50 is used to filter the light beams emitted by each of the LED lamp beads 20.

[0037] Specifically, Figures 1 to 4 For the LED display module, a plurality of LED lamp beads 20 are arranged on the substrate 10. In the present invention, the substrate can be exemplarily a metal substrate, a FR-4 substrate, a ceramic substrate or other forms of LED substrates. The substrate is a carrier on which each LED lamp bead is installed.

[0038] The LED lamp bead 20 can be exemplarily a 1010 lamp bead, a 1515 lamp bead, a 3535 lamp bead, a 1515 lamp bead or the lamp bead 20 of other specifications and models.

[0039] In the utility model, each of the LED lamp beads 20 is welded and set on the substrate 10. When the substrate 10 is naturally placed flat, each of the LED lamp beads 20 is set on the upper surface of the substrate 10, and each of the LED lamp beads 20 is arranged in an array, with a spacing between each of the LED lamp beads 20, and they are arranged at intervals from each other.

[0040] On the substrate 10, the solid glue layer 30 is provided, and the solid glue layer 30 can wrap each of the LED lamp beads 20, that is, the solid glue layer 30 is provided at the intervals between each of the LED lamp beads 20 and on the outer surface of each of the LED lamp beads 20. In the specific setting, the area between each of the LED lamp beads 20 is filled with solid glue, and the upper surface of each of the LED lamp beads 20 is also filled with solid glue, which together form the solid glue layer 30. Through the setting of the solid glue layer 30, each of the LED lamp beads 20 can be more firmly arranged on the substrate 10, and the solid glue layer 30 can be made of materials such as polyaspartate, epoxy glue or silicone.

[0041] In addition, the provision of the solid glue layer 30 can also prevent the LED lamp beads 20 from being disturbed by the external environment, such as moisture, dust, dew, etc., to ensure the performance and life of the LED lamp beads 20. In addition, the provision of the solid glue layer 30 can also increase the structural strength of the LED display module 100, improve the overall mechanical strength, and make each LED lamp bead 20 more stable and avoid damage due to external impact.

[0042] Furthermore, the LED display module provided by the present invention is as follows: Figure 3 , Figure 4 and Fig.12 As shown, a light shielding layer 40 is covered on the solid glue layer 30 , and the light shielding layer 40 has a plurality of openings 41 , and the openings 41 correspond one by one to the light emitting areas 21 of the LED lamp beads 20 , and the openings 41 can reveal the light emitting areas 21 of each of the LED lamp beads 20 .

[0043] By setting the light shielding layer 40, only the light emitting area 21 of each LED lamp bead 20 is exposed on the entire substrate 10. The chromaticity of other positions outside the light emitting area 21, that is, the substrate 10 and the plastic bracket 22 of each LED lamp bead 20, can be unified to the same chromaticity due to the existence of the light shielding layer 40, thereby achieving the effect of improving the product contrast, enhancing the clarity and readability of the displayed image, and improving the user experience.

[0044] Therefore, in the utility model, by setting the shading layer 40, in the manufacturing process of the LED display module 100, there is no need to perform additional printing steps on the substrate 10; and there is no need to perform additional printing on each surface of the LED lamp bead 20, and there is no need to unify the color of the plastic bracket 22 of each LED lamp bead 20, thereby achieving the effect of improving and optimizing the process flow and saving costs.

[0045] The light shielding layer 40 in the present invention has the function of absorbing light, that is, it is opaque, so that when the LED display module 100 is in a natural state, only the light-emitting area 21 of each LED lamp bead 20 is exposed, and the colors of other parts remain consistent.

[0046] In a possible implementation, the shading layer 40 may be white, so that the LED display module 100 can be used in situations where it is placed on a white wall for display; of course, the shading layer 40 may also be black, which is the conventional design of the display module; in addition, the shading layer 40 may also be set to other colors, such as green, blue, etc., according to user needs, so as to achieve the effect of meeting user-specific needs and improving the flexibility of use of the LED display module 100.

[0047] Specifically, in the present invention, the light shielding layer 40 can be formed by silk screen printing, laser hole washing or drill hole washing.

[0048] Furthermore, in order to reduce the blue light in the light beam emitted by each of the LED lamp beads 20 in the LED display module 100, the utility model further provides the light filtering structure 50 on the solid glue layer 30, and the light filtering structure 50 is used to filter the light beam emitted by each of the LED lamp beads 20. The light filtering structure 50 is specifically the light filtering structure 50 that can filter out light beams with a wavelength below 430nm.

[0049] The blue light is specifically a light beam with a wavelength between 400nm and 500nm. Therefore, in the present invention, through the setting of the filtering structure 50, part of the blue light emitted by each of the LED lamp beads 20 can be filtered to reduce the harm of the light beam emitted by the LED display module 100 to the human eye, thereby achieving the effect of protecting the human eye.

[0050] In addition, the filter structure 50 can also filter external natural light and ambient light. For example, ultraviolet light beams with a wavelength below 390nm in natural light can be filtered. When the ultraviolet light beam enters the LED display module 100, it may cause the solid glue layer 30, the LED lamp beads 20 and the substrate 10 to turn yellow. Therefore, in the utility model, through the setting of the filter structure 50, the ultraviolet light beam of natural light can be filtered to prevent the ultraviolet light beam from damaging the LED display module 100, thereby achieving the effect of increasing the service life of the LED display module 100.

[0051] Further, in a possible implementation manner, as Figure 1 and Figure 3 As shown, the light shielding layer 40 may be disposed on the outer surface of the light filtering structure 50, or; Figure 2 and Figure 4 As shown, the light filtering structure 50 can be arranged on the outer surface of the light shielding layer 40, the light shielding layer 40 is arranged on the outer surface of the solid glue layer 30, and the light shielding layer 40 is located between the solid glue layer 30 and the light filtering structure 50. Specifically, the position of the light filtering structure 50 is arranged. Figure 1 and Figure 3 As shown, the light shielding layer 40 can be arranged on the outer surface of the filter structure 50 , that is, the filter structure 50 is arranged on the outer surface of the solid glue layer 30 , and the light shielding layer 40 is arranged at the outermost side of the LED display module 100 .

[0052] Or, if Figure 2 and Figure 4 As shown, the light filter structure 50 can also be arranged on the outer surface of the light shielding layer 40, and the light shielding layer 40 is arranged on the outer surface of the solid glue layer 30, that is, the light filter structure 50 is arranged at the outermost side of the LED display module 100, and the light shielding layer 40 is arranged between the solid glue layer 30 and the light filter structure 50. Users can choose according to actual conditions.

[0053] Further, in a possible implementation, the filter structure 50 is a filter structure 50 that has been sprayed or soaked with a hardener. Specifically, before the filter structure 50 is installed, the filter structure 50 may be sprayed or soaked with a hardener to enhance the scratch resistance of the filter structure 50.

[0054] In addition, an anti-fingerprint agent layer (not shown) may be added to the outermost layer of the LED display module 100 to prevent fingerprints from sticking and improve the hydrophobicity of the LED display module 100. When the light filter structure 50 is disposed on the outer surface of the light shielding layer 40, the anti-fingerprint agent layer is disposed on the outer surface of the light filter structure 50; when the light shielding layer 40 is disposed on the outer surface of the light filter structure 50, the anti-fingerprint agent layer is disposed on the outer surface of the light shielding layer 40.

[0055] Further, in a possible implementation, the opening 41 is circular, elliptical or rectangular. That is, the opening 41 of the light shielding layer 40 can be circular, elliptical or rectangular. In particular, when the filter structure 50 can also be disposed on the outer surface of the light shielding layer 40, the size of the opening 41 and the light emitting area 21 of the LED lamp bead 20 is set to be circular, elliptical or rectangular.

[0056] Specifically, the opening 41 of the light shielding layer 40 can be a circle with the same diameter as the light emitting area 21 of the LED lamp bead 20, or a circle or ellipse that is larger or smaller than the light emitting area 21 by 2 mm. Of course, the opening 41 can also be rectangular, such as a square or a rectangle.

[0057] For example, if the diameter of the light-emitting area 21 of the LED lamp bead 20 is 1.6 mm, the shading layer 40 can be made on the filter structure 50, and the shading layer 40 is provided with a light-transmitting hole (i.e., the opening 41) corresponding to the light-emitting area 21 of the LED lamp bead 20. The size of the opening 41 can be a square with a length of 1.6 mm and a width of 1.6 mm. Moreover, the size of the opening 41 can be adjusted in the shading layer 40 according to the size of the light-emitting area 21 of the LED lamp bead 20. For example, if the diameter of the light-emitting area 21 of the LED lamp bead 20 is 2.5 mm, the opening 41 can be set to a rectangle with a size of 3.0 mm and a width of 2.0 mm. Further, for the specific structure of the filter structure 50, such as Figures 6 to 11 As shown, the filter structure 50 can be a multi-layer structure.

[0058] like Figures 9 to 11 As shown, the filter structure 50 includes: a PET adhesive layer 52 and an anti-blue light agent adhesion layer 53, wherein the PET adhesive layer 52 is disposed on the solid adhesive layer 30, and the anti-blue light agent adhesion layer 53 is adhered to the surface of the PET adhesive layer 52. Fig. 9 As shown, the anti-blue light agent adhesion layer 53 can be arranged on the outer surface of the PET adhesive layer 52; Fig.10 As shown, the anti-blue light agent adhesion layer 53 can also be arranged on the inner surface of the PET adhesive layer 52; as shown in Figure 11, of course, the anti-blue light agent adhesion layer 53 can also be arranged on both the inner and outer surfaces of the PET adhesive layer 52.

[0059] certainly Figures 9 to 11 The PET adhesive layer 52 in the figure can also be replaced by a layered structure of other materials. Figures 6 to 8 The filter structure 50 includes: a PC glue layer 51 and an anti-blue light agent adhesion layer 53, wherein the PC glue layer 51 is disposed on the solid glue layer 30, and the anti-blue light agent adhesion layer 53 is adhered to the surface of the PC glue layer 51. Figure 6 As shown, the anti-blue light agent adhesion layer 53 can be disposed on the outer surface of the PC adhesive layer 51; Figure 7 As shown, the anti-blue light agent adhesion layer 53 can also be arranged on the inner surface of the PC adhesive layer 51; as shown in FIG. 8 , of course, the anti-blue light agent adhesion layer 53 can also be arranged on both the inner and outer surfaces of the PC adhesive layer 51.

[0060] Furthermore, if Figure 5 As shown, the filter structure 50 may also be a single-layer structure, wherein the filter structure is a mixed single-layer structure made by mixing PC glue and anti-blue light agent. Alternatively, the filter structure 50 may also be a mixed single-layer structure made by mixing PET glue and anti-blue light agent.

[0061] That is, an anti-blue light agent is mixed into PC glue or PET glue to form a layered structure to form the single-layer filter structure 50 .

[0062] Thus, in the present invention, the anti-blue light agent can be introduced into the LED display module 100 by using PC glue or PET glue as a carrier. PC glue or PET glue as a carrier can help to evenly distribute the anti-blue light agent in the LED display module 100, avoiding the problem of differences in light transmittance due to uneven concentration in local areas, thereby ensuring that the filtering light beam effect of the entire LED display module 100 is uniform.

[0063] Further, in a possible implementation manner, as Fig.12 and Fig.13 As shown, the plastic bracket 22 can be specifically made of polyphthalamide plastic, polycyclohexylene dimethylene terephthalate resin plastic or epoxy resin molding plastic. Of course, it is not limited to this. The plastic bracket 22 can also be made of other plastic materials.

[0064] Further, in a possible implementation, a plurality of polarity pads 23 are provided at the bottom of the LED lamp bead 20, and the LED lamp bead 20 is soldered to the substrate 10 through the polarity pads 23. The number of the polarity pads 23 can be selected according to the actual application, such as the size of the LED lamp bead 20, etc. The utility model is described as a single LED lamp bead 20 having two polarity pads 23 at the bottom, but is not limited thereto.

[0065] The present invention also provides an LED display device, which includes: a device body, and the LED display module 1000 described above, wherein the LED display module 100 is arranged in the device body. Since the LED display module 100 has been described in detail above, it will not be described again here.

[0066] It should be noted that the present invention takes an LED display module and an LED display device as an example to introduce the specific structure and working principle of the present invention, but the application of the present invention is not limited to LED display modules and LED display devices, and can also be applied to the use of other similar workpieces.

[0067] It should be understood that the present invention is not limited to the precise structure described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
