[0020] Referring to FIG. 1, in some preferred embodiments, the disclosed LED floor screen includes a support base 10 and an LED display screen 20 mounted on the support base 10. Here, the support base 10 includes a plurality of holders 11 and a plurality of support rods 12. The support rods 12 are connected to two adjacent holders 11. The support base 10 is formed with a plurality of placement positions 13 surrounded by the holders 11 and the support rods 12, and a limiting portion 14 is formed at the upper end of each holder 11 (also see FIG. 3). The LED display screen 20 includes a plurality of LED display modules 21. As shown in FIG. 2, the LED display module 21 includes an LED display panel 210, a first tempered glass plate 212 mounted on the front of the LED display panel 210 via a first optical adhesive film 211, and a second tempered glass plate 214 mounted on the back of the LED display panel 210 via a second optical adhesive film 213. The LED display panel 210, the first tempered glass plate 212, and the second tempered glass plate 214 are laminated together to form an integrated unit. A plurality of LED display modules 21 are arranged corresponding to a plurality of placement positions 13 so as to be supported by the holder 11 and the support rods 12, and are joined to the LED display screen 20 by restricting the LED display modules 21 with the restricting portions 14. The LED display modules 21 of the disclosed LED floor screen are integrally manufactured using the double-sided adhesive tempered glass plate laminated LED display panel 210, and have excellent load-bearing capacity. Moreover, the LED display modules 21 can be directly placed at the placement positions 13 formed on the support seat 10 and positioned with the restricting portions 14, thereby joining to the LED display panel 20, improving the convenience of joining the LED floor screen.

[0021] Preferably, the first tempered glass plate 212 and the second tempered glass plate 214 have a thickness of 6 mm to 15 mm, and suitable tempered glass plates, such as conventional commercially available ultra-white tempered glass, can be selected. When manufacturing the LED display module 21 by laminating, the tempered glass substrate often needs to be washed and dried to remove foreign matter such as dust adhering to it. First, the tempered glass substrate is washed with water, acid, or alkali, or a combination thereof, and then placed in a clean environment and dried by a method such as fan purging or heat drying.

[0022] The first optical adhesive film 211 and the second optical adhesive film 213 can be made of conventional commercially available transparent non-conductive optical adhesives such as, but not limited to, ethylene-vinyl acetate copolymer (EVA) adhesive film and polyvinyl butyral (PVB) adhesive film.

[0023] The LED display panel 210 can be selected from conventional LED display panels, including openwork and non-openwork LED display panels. Generally, the LED display panel 210 includes a substrate, a conductive circuit formed on the substrate, and a plurality of LED beads welded to the conductive circuit. The conductive circuit may be printed on the substrate using a conductive paste such as silver paste, tin paste, or copper paste, or may be formed by cutting copper foil and then attaching it to the substrate, or may be fabricated by directly etching copper foil onto the substrate. The LED beads can be patch-type LEDs, which can be welded to the conductive circuit using a conventional welding method such as reflow welding. In some embodiments, an LED driver chip can also be welded to the conductive circuit at the same time.

[0024] 1, in some preferred embodiments, a cushion pad 15 is fixed to the upper surface of the support rod 12. The cushion pad 15 serves to protect the LED display module 21. Generally, the cushion pad 15 can be made of a soft elastic material such as rubber or polyurethane.

[0025] 1 and 3, in the embodiment shown in the drawings, the holder 11 includes support legs 110, a support plate 111 fixed to the upper ends of the support legs 110, and a shim 112 provided on the support plate 111. The limiting portion 14 includes a plurality of stoppers 140 formed by protruding from the upper surface of the shim 112, and the side surfaces of the stoppers 140 abut against the side surfaces of the LED display module 21. In this way, the LED display module 21 is restricted from different directions by the stoppers 140 of the plurality of limiting portions 146, and thus the LED display module 21 is positioned at the arrangement position 13.

[0026] The support plate 111 is formed with a number of connecting plates 1110 distributed along the outer edge of the support plate 111. The support rod 12 is designed as a hollow square tube. The connecting plates 1110 are inserted into the ends of the support rod 12 to support the support rod 12, and the connecting plates 1110 and the support rod 12 are connected by screws (not shown). In this way, the support base 10 can be easily removed and assembled.

[0027] In the embodiment shown in the drawings, the placement positions 13 are designed as rectangular structures. That is, each placement position 13 is surrounded by four holders 11 arranged in a rectangular pattern and four support rods 12 connected between each two linearly adjacent holders 11. Correspondingly, the LED display module 21 is also designed as a rectangular structure that fits the placement positions 13. The support plate 111 has four connecting plates 1110 uniformly distributed along the outer edge of the support plate 111. The limiting portion 14 includes four stoppers 140 uniformly distributed around the center of the shim 112, and the four stoppers 140 correspond to the positions of the four connecting plates 1110. In this way, rectangular placement positions 14 are formed, and the rectangular LED display module 21 is directly placed on the corresponding placement position 14, supported by the holders 11 and support rods 12, and limited by the blocks 140 at the four corners, thereby achieving stable installation of the LED display module 21. Of course, in other embodiments, the placement position 14 and the LED display module 21 may be designed as other suitable shapes.

[0028] Preferably, the support legs 110 are height-adjustable support legs to allow the LED floor screen to fit on uneven ground. As shown in Fig. 3, in this embodiment, the support legs 110 include a support base plate 1100, a sleeve 1101 with an internal thread fixed to the support base plate 1100, and a screw 1102 threaded into the sleeve 1101, and the support plate 111 is fixed to the upper end of the screw 1102.

[0029] As shown in FIGS. 1, 4, and 5, a periphery of the LED display screen 20 is provided with a border unit 30. The border unit 30 includes a plurality of border members 300 (only some of the border members 300 are shown in the drawings) joined together in series to surround the LED display screen 20. The border member 300 includes a top plate 301 and an outer plate 302 bent vertically downward from the outer edge of the top plate 301. At least one insertion post 303 is formed on the inner side of the underside of the top plate 301. An insertion hole 120 corresponding to the insertion post 303 is formed on the upper surface of the support rod 12. The insertion post 303 is inserted into the insertion hole 120 to fix the border member 300 to the outer side of the LED display screen 20. The installation of the border unit 30 serves to protect the LED display screen 20 and to decorate and beautify the LED floor screen.

[0030] As shown in FIGS. 1 and 4 , in some preferred embodiments, a tilting unit 40 is provided on the outer side of at least a portion of the edging unit 30. The tilting unit 40 includes a plurality of sloped members 400 joined together in series. The sloped member 400 includes an inner plate 401 and a convex arc-shaped sloped plate 402 extending from the upper end of the inner plate 401 at an angle outward. Each sloped member 400 has an end plate 403 formed on at least one end surface thereof, extending from the side edge of the inner plate 401 to the side edge of the sloped plate 402. The inner plate 401 is attached to the outer plate 302 of the edging unit 300. In practical applications, the installation of the tilting unit 40 can be determined depending on the environment of the usage scene. For example, if the LED floor screen is installed in an environment with walls, the tilting unit 40 is not installed on the edge close to the wall. If the LED floor screen is installed in the center of the usage location, the tilting unit 40 can be installed on the periphery of the LED floor screen. By installing this tilt unit 40, safety during use of the LED floor screen (for example, reducing the risk of employees tripping or falling) and barrier-free passage are ensured, while the design of the LED floor screen can be improved.

[0031] The above is merely a preferred embodiment of the present invention, and does not impose any formal limitations on the present invention. Those skilled in the art may make various equivalent modifications and improvements based on the above embodiment. Any equivalent modifications or modifications made within the scope of the utility model registration claims shall fall within the protection scope of the present invention.
