Technical Field
[0001] This utility model relates to the field of LED display technology, specifically a recessed LED display module. Background Technology
[0002] With the continuous advancement of LED display technology, the market demand for thinner, lighter, and better-performing LED displays is growing. However, existing LED displays are not only bulky but also typically require the splicing of multiple LED display modules. Each module consists of multiple components such as a base shell, LED display panels, and a mask. Due to the gaps between adjacent components, light emitted from the LED display panels can easily leak from the sides, resulting in high brightness at the splicing points of adjacent LED display modules and a poor overall display effect. To address this, the industry commonly uses light-shielding cotton pasted on the side walls of the LED display cabinet to reduce light leakage. However, this method also has limitations. Because the light-shielding cotton pasted on the side walls is far from the modules, the gaps widen when the splicing angle of the modules is too large. At this point, the light-shielding cotton farther from the modules cannot completely cover the gaps, resulting in a poor light-shielding effect. Increasing the thickness of the light-shielding cotton on the side walls can cover the gaps, but with the trend towards thinner and lighter LED displays, excessively thick light-shielding cotton can affect the flatness of the module splicing. Therefore, how to make LED displays thin and light while solving the problem of side light leakage is a technical problem that researchers in this field urgently need to solve. Utility Model Content
[0003] To solve the above problems, this utility model provides a recessed LED display module, including a bottom shell, an LED display board and a face mask. The face mask is located on the front of the bottom shell, and the LED display board is located between the bottom shell and the face mask. The side wall of the bottom shell is provided with a recessed first step surface and a second step surface. The first step surface is close to the side of the face mask, and a groove is formed on the first step surface. Light-blocking cotton is placed in the groove.
[0004] Preferably, the thickness of the light-blocking cotton is a, the depth of the groove is b, and 2b≥a≥b.
[0005] Preferably, the light-blocking cotton is made of cotton or sponge.
[0006] Preferably, the first step surface is inclined relative to the second step surface, and the angle of inclination between the first step surface and the second step surface is 10 to 45°.
[0007] Preferably, the bottom shell is provided with magnetic suction holes that are staggered and evenly distributed, and magnetic suction blocks are embedded in the magnetic suction holes.
[0008] Preferably, the bottom shell has magnetic holes at its four corners, with magnetic blocks embedded in the holes, and a nut post with threaded holes on the bottom shell.
[0009] Preferably, there are ten nut posts, which are staggered and evenly distributed on the bottom shell.
[0010] Preferably, two handle slots are provided on the back of the bottom shell, and handles are provided in the handle slots.
[0011] The beneficial effects are as follows: This application provides a thin and light-leakage recessed LED display module with no side light leakage. By adopting a recessed design, most of the module volume is embedded in the LED display cabinet, reducing the volume of the exposed module and achieving the purpose of reducing the overall thickness of the LED display. At the same time, a groove is opened on the first step surface, and light-shielding cotton is placed in the groove, which brings the light-shielding cotton closer to the LED display panel, which is more conducive to light blocking. Furthermore, even if the thickness of the light-shielding cotton is increased, it can be compressed into the groove during the splicing of the modules without affecting the splicing flatness of the LED display. Thus, a thin and light design can be achieved while solving the side light leakage problem, resulting in a better visual experience. Attached Figure Description

[0020] Example
[0021] Please see Figure 3 , Figure 3 This is an exploded view of the recessed LED display module. This embodiment provides a recessed LED display module, which is installed on an LED display cabinet during use. The recessed LED display module includes a base shell 1, an LED display panel 2, and a face mask 3. The face mask 3 is located on the front of the base shell 1, and the LED display panel 2 is located between the base shell 1 and the face mask 3. The LED display panel 2 can be fixed to the base shell 1 with screws, and the face mask 3 can be fixed to the LED display panel 2 by adhesive or screws.
[0022] See also Figure 3 Please refer to the following for further details. Figure 1 , Figure 1This is a schematic diagram of the rear structure of the recessed LED display module. The bottom shell 1 is mounted on the LED display cabinet. The bottom shell 1 has at least 14 magnetic suction holes 113, which are staggered and evenly distributed. Magnetic blocks 114 are embedded within each magnetic suction hole 113. The magnetic blocks 114 can be magnetized magnets. A permanent magnet is located inside the LED display cabinet. The magnetic blocks 114 and the permanent magnet attract each other, magnetically connecting the recessed LED display module to the LED display cabinet. This magnetic attraction method allows for quick disassembly and assembly of the recessed LED display module and the LED display cabinet, greatly improving work efficiency. To reduce costs, this embodiment also provides another design: magnetic suction holes 113 are provided at the four corners of the bottom shell 1, with magnetic blocks 114 embedded within each hole. Nut posts 115 with threaded holes are provided on other parts of the back of the bottom shell 1, with the threaded holes staggered from the magnetic suction holes 113. The number of nut posts 115 can be reasonably set according to the area of the LED display module. For example, on an LED display module that is 1 meter long and 0.5 meters wide, the preferred number of nut posts 115 is 10, which are staggered and evenly distributed on the back of the bottom shell 1. Through holes are provided on the LED display cabinet, and fasteners such as screws are threaded through the through holes and screwed onto the nut posts 115, thereby securing the recessed LED display module to the LED display cabinet. Compared with the magnetic connection method, the screw connection method is more cost-effective. However, using only the screw connection method results in slower installation and disassembly, and the bolts at the top corners are difficult to remove. Therefore, using a combination of magnetic and screw connections can not only save costs to the greatest extent but also speed up the installation and disassembly of the LED display module. Whether using a full magnetic connection method or a combination of magnetic and screw connections, a single mold can be used when manufacturing the bottom shell using injection molding, eliminating the need for additional molds and saving mold costs.
[0023] See also Figure 1 and Figure 3 The side wall 11 of the base shell 1 has a recessed first step surface 111 and a second step surface 112. The first step surface 111 is closer to the face mask 3. This recessed step design allows most of the volume of the base shell 1 to be embedded in the LED display cabinet, reducing the volume of the exposed modules. This not only reduces the overall thickness of the LED display but also reduces the chance of damage to the modules during transportation and ensures that adjacent base shells do not collide when modules are spliced. To improve the impact resistance of the modules, highly elastic buffer protective sleeves can be added to the four corners of the first step surface 111. The first step surface 111 is inclined relative to the second step surface 112, and the angle of inclination between the first step surface 111 and the second step surface 112 is 10-45°. This inclined design ensures that multiple modules can be spliced to form LED displays with various degrees of curvature, meeting diverse curved display requirements.
[0024] Please see Figure 2 , Figure 2 This is an enlarged view of part A of the recessed LED display module. A groove 1111 is formed on the first step surface 111, and light-shielding cotton is placed inside the groove 1111. The light-shielding cotton can be fixed inside the groove 1111 by adhesive. The light-shielding cotton is made of cotton or sponge, preferably with a density of 50-60 kg / m³. 3 The light-blocking cotton is made of sponge. This sponge not only ensures a certain degree of softness so that it can be compressed into the groove 1111, but also provides good light-blocking properties and is durable. The thickness of the light-blocking cotton is 'a', and the depth of the groove 1111 is 'b', where 2b ≥ a ≥ b. This design allows the light-blocking cotton to be closer to the LED display panel 2, which is more conducive to light blocking. Furthermore, even if the thickness of the light-blocking cotton is increased, it can be compressed into the groove 1111 during the splicing module process without affecting the splicing flatness of the LED display screen.
[0025] See also Figure 1 and Figure 3 Two handle slots 116 are provided on the back of the bottom shell 1. Each handle slot 116 contains a handle 1161 and a handle cover 1162. The handle cover 1162 is fixedly connected to the handle slot 116. The handle 1161 is inserted into the handle cover 1162. The handle cover 1162 has a through hole, through which a fastener passes and abuts against the handle 1161, locking the handle 1161 within the handle cover 1162. This also allows the handle 1161 to rotate relative to the handle slot 116. The handles facilitate the transport and installation of this recessed LED display module, enhancing portability.
[0026] In summary, this embodiment provides a thin and light-leakage recessed LED display module. By adopting a recessed design, most of the module's volume is embedded in the LED display cabinet, reducing the exposed module volume and achieving the goal of reducing the overall thickness of the LED display. At the same time, a groove 1111 is provided on the first step surface 111, and light-shielding cotton is provided in the groove 1111, bringing the light-shielding cotton closer to the LED display panel 2, which is more conducive to light blocking. Furthermore, even if the thickness of the light-shielding cotton is increased, it can be compressed into the groove 1111 during the splicing process without affecting the splicing flatness of the LED display. Thus, a thin and light design can be achieved while solving the side light leakage problem, resulting in a better visual experience.
