The base, LED display panel and transparent panel are bonded into a whole by lamination.
[0007] Furthermore, a sealant portion is formed between the channel portion and the first through hole to seal the gap between them.
[0008] Furthermore, the sealant portion is formed by the first optical adhesive layer and / or the second optical adhesive layer being cast into the gap between the channel portion and the first through hole during lamination.
[0009] Furthermore, the lower end of the channel portion extends out of the first through hole.
[0010] Furthermore, a reinforcing rib is formed on the lower surface of the base, the reinforcing rib including a plurality of first reinforcing ribs formed longitudinally on the lower surface of the base and a plurality of second reinforcing ribs formed laterally on the lower surface of the base and distributed intersecting with the first reinforcing ribs.
[0011] Furthermore, the base has a positioning flange formed along its upper surface edge, and the transparent panel has a positioning step that matches the positioning flange along its lower surface edge, with the positioning flange inserted into the positioning step.
[0012] Furthermore, the base adopts a rectangular structure, with all four sides being inclined surfaces at a 45° angle from top to bottom.
[0013] Furthermore, the perforation rate of the transparent panel is 5% to 70%.
[0014] Furthermore, screws are used to pass through the transparent panel and the LED display panel and screw them onto the base; a receiving portion is formed on the base, the control card of the LED display is disposed in the receiving portion, a cover plate is used to cover the receiving portion, and the receiving portion is filled with sealant; the power supply of the LED display is a DC-DC power supply; the base is made of acrylic or polycarbonate plastic, and the transparent panel is made of acrylic or polycarbonate plastic.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] It should be understood that, in the description of this utility model, unless otherwise expressly specified and limited, the terms "first", "second", ... are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated; the terms "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation or be constructed in a specific orientation.
[0027] refer to Figures 1 to 4In some preferred embodiments, the disclosed LED display screen 1 includes a base 10, an LED display panel 20, and a transparent panel 30. The base 10 has a receiving position 11 formed on its upper surface, and a plurality of first through holes 12 vertically penetrating the base 10 are formed on the receiving position 11. The LED display panel 20 is disposed in the receiving position 11 and has a plurality of hollow holes 21 corresponding to the first through holes 12. The transparent panel 30 covers the LED display panel 20 and has a plurality of second through holes 31 corresponding to the first through holes 12. The second through hole 31 includes a cylindrical channel portion 310 extending downward around the edge of the second through hole 31. The channel portion 310 passes through the corresponding hollow hole 21 and is inserted into the corresponding first through hole 12. Thus, through the arrangement of the first through hole 12, the perforated hole 21, and the second through hole 31 with a channel portion 310, and by having the channel portion 310 pass through the perforated hole 21 and insert into the first through hole 12, multiple water-permeable channels are formed on the LED display screen 1, penetrating the screen body. By providing these multiple water-permeable channels, the air and water permeability of the LED display screen 1 can be effectively improved, enabling display devices constructed using the LED display screen 1 (such as...) Figure 8 The columnar display shown or as Figure 9 When the stage (or similar structure) rises and falls in water, air and water can circulate through the permeable channels, preventing air and water trapping and thus facilitating the smooth raising and lowering of the display device. Furthermore, the multiple permeable channels also facilitate the drainage of water accumulated on the LED display screen 1. In addition, the presence of multiple second through-holes 31 on the transparent panel 30 provides the LED display screen 1 with an anti-slip effect.
[0028] Admittedly, the LED display screen 1 disclosed in this utility model is not limited to the construction of such... Figure 8 The columnar display shown and such Figure 9 The stage shown can also be used to construct display devices of other shapes or structures, such as floor displays.
[0029] In some preferred embodiments, the LED display panel 20 can be sandwiched between the base 10 and the transparent panel 30 using a transparent non-conductive optical adhesive. Referring to the accompanying drawings, a first optical adhesive layer 40 is disposed between the LED display panel 20 and the base 10, and a second optical adhesive layer 50 covering the LED display panel 20 is disposed between the transparent panel 30 and the LED display panel 20. The base 10, LED display panel 20, and transparent panel 30 are bonded together as a whole through lamination. Thus, the first optical adhesive layer 40 and the second optical adhesive layer 50 encapsulate the LED display panel 20 between them, providing both waterproofing and protection for the LED display panel 20. Simultaneously, during lamination, the first optical adhesive layer 40 and the second optical adhesive layer 50 can flow into the gaps between the base 10, the LED display panel 20, and the transparent panel 30, thereby improving the waterproof rating of the LED display screen 1.
[0030] Preferably, a sealant portion (not shown in the figure) is formed between the channel portion 310 and the first through hole 12 to seal the gap between them, thereby preventing water from flowing into the LED display panel 20 from the gap between the channel portion 310 and the first through hole 12, ensuring the waterproof performance of the LED display screen. This sealant portion can be formed by the first optical adhesive layer 40 and / or the second optical adhesive layer 50 being cast into the gap between the channel portion 310 and the first through hole 12 during lamination. The first optical adhesive layer 40 and the second optical adhesive layer 50 can be optical adhesive films, which are laminated to bond the base 10, the LED display panel 20, and the transparent panel 30. During manufacturing, through holes for the channel portion 310 to pass through can be machined into the optical adhesive film. Optical films can be selected from, but are not limited to, ethylene-vinyl acetate copolymer (EVA) films, polyvinyl butyral (PVB) films, and other existing transparent non-conductive optical adhesives available on the commercial market.
[0031] like Figure 5 As shown, in this preferred embodiment, the lower end of the channel portion 310 extends out of the first through hole 12. This can prevent optical adhesive from flowing into and adhering to the channel portion 310 during the lamination process, and can also increase the sealant portion formed between the channel portion 310 and the first through hole 12, thereby improving the sealing performance.
[0032] In the embodiment shown in the accompanying drawings, the first through hole 12, the hollow hole 21, and the second through hole 31 are all designed as matching elongated holes. Of course, those skilled in the art will understand that the first through hole 12, the hollow hole 21, and the second through hole 31 can also be designed as other regular or irregular holes, such as circles.
[0033] As shown in the attached figures, the second through holes 31 are uniformly distributed on the transparent panel 30. Generally, the perforation rate of the transparent panel 30 (i.e., the ratio of the perforated area of the second through holes 31 to the area of the transparent panel 30) is set between 5% and 70%.
[0034] like Figure 2 and Figure 4 As shown, in some preferred embodiments, a reinforcing rib 13 is formed on the lower surface of the base 10. The reinforcing rib 13 includes a plurality of first reinforcing ribs 130 formed longitudinally on the lower surface of the base 10 and a plurality of second reinforcing ribs 131 formed laterally on the lower surface of the base 10 and intersecting with the first reinforcing ribs 130. By providing the reinforcing rib 13, the load-bearing capacity of the LED display screen can be significantly improved.
[0035] In the preferred embodiment shown in the accompanying drawings, the base 10 has a positioning flange 14 formed along its upper surface edge, and the transparent panel 30 has a positioning step 32 matching the positioning flange 14 formed along its lower surface edge. The positioning flange 14 is inserted into the positioning step 32. The cooperative arrangement of the positioning flange 14 and the positioning step 32 ensures that the transparent panel 30 is accurately installed on the base 10, and enhances the seal between the transparent panel 30 and the base 10, improving the waterproof performance of the LED display screen, especially when a second optical adhesive layer 50 is provided between the LED display panel 20 and the transparent panel 30.
[0036] Preferably, the base 10 and the transparent panel 30 can be made of transparent materials such as acrylic (Polymeric MethylMethacrylate; PMMA) or polycarbonate (PC), which have the advantage of being lightweight and can reduce the overall weight of the LED display screen.
[0037] See Figure 1 and Figure 3 In some embodiments, screws 60 can be used to pass through the transparent panel 30 and the LED display panel 20 and screw them onto the base 10. This further ensures the firmness of the connection between the transparent panel 30, the LED display panel 20 and the base 10.
[0038] Preferably, the base 10 adopts a rectangular structure, with all four sides designed as sloping surfaces inclined inward at 45° from top to bottom. Therefore, combined with Figure 7 As shown, a 90-degree seamless splicing between two LED displays 1 can be achieved, which facilitates the installation of LED displays.
[0039] The LED display panel 20 can be an existing LED display panel with perforated holes. Combined with... Figure 6As shown, in some embodiments, the LED display panel includes a substrate 22, a conductive line formed on the substrate 22 (not shown), and a plurality of LED beads 23 soldered to the conductive line. A plurality of perforated holes 21 are uniformly distributed on the substrate 22. The substrate 22 can be made of a phenolic paper substrate, a metal substrate, a fiberglass substrate, or a composite substrate (e.g., CEM-3). The perforated holes 21 are formed on the LED substrate 22 using suitable processing methods such as drilling or laser drilling. The conductive line is located in the non-perforated area of the substrate 22. It can be formed by printing conductive pastes such as silver paste, solder paste, or copper paste onto the non-perforated area of the substrate 22, or by cutting copper foil and placing it in the non-perforated area of the substrate 22, or by directly etching copper foil onto the substrate 22. The LED beads 23 can be surface-mount LEDs, which can be soldered to the conductive line using existing soldering methods such as reflow soldering. In some embodiments, the LED driver chip can also be soldered and fixed to the conductive line at the same time. The arrangement of the conductive line and its connection with the LED bead 23 and the LED driver chip can be carried out using existing technology, and will not be described in detail here.
[0040] Combination Figure 3 and Figure 4 As shown, a receiving portion 15 is formed on the base 10, and the control card 70 of the LED display screen is disposed in the receiving portion 15. A cover plate 80 covers the receiving portion 15, and sealant is used to fill the receiving portion 15. In some preferred embodiments, the power supply 90 of the LED display screen uses a DC-DC power supply, such as a 400V DC input DC-DC power supply. Compared with AC-DC power supply, using a DC-DC power supply is safer, especially in underwater environments. In the embodiment shown in the figures, the power supply 90 is fixed to the back of the base 10; however, the power supply 90 can also be fixed in other locations. The electrical connection between the control card 70 and the power supply 90 can be made using existing technology and will not be described in detail here.
[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Those skilled in the art can make various equivalent changes and improvements based on the above embodiments. All equivalent changes or modifications made within the scope of the claims should fall within the protection scope of the present utility model.
