Detailed implementation mode

[0022] In order to more clearly illustrate the purpose, technical solution and advantages of the embodiments of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. A clear and complete description is made. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention. In addition, the directional terms mentioned in the present invention, for example, "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., are only references to the directions of the attached drawings. The directional terms used are for better and clearer illustration and understanding of the present invention, rather than indicating or implying the orientation that the present invention must have. Therefore, it cannot be understood as a limitation to the present invention.

[0023] Examples of the present invention are as follows Figures 1 to 6As shown in the figure, an anti-glare LED display screen includes a display screen body 1 with a plurality of LED lamp beads 10 arranged at intervals in a row and column structure on the top surface. The display screen body 1 includes a display module, a control system, and a power supply system. The LED lamp beads 10 of the display module are arranged in a row and column structure, and the upper part of the LED lamp beads 10 protrudes outwards. Preferably, the display screen body 1 is a small-pitch LED display screen body. In this way, the pixel pitch of the display screen is small, and the resolution per unit area is high, so that higher-definition graphics, images, and videos can be displayed, more channels of videos and image frames can be displayed, and the displayed colors are natural and real. At the same time, the display screen can be completely seamless. A panel 2 for anti-glare is also covered on the top surface of the display screen body 1. The panel 2 is used to reduce the glare intensity so as to achieve the purpose of anti-glare. Panel through holes 20 for the LED lamp beads 10 to pass through are provided on the panel 2. The upper part of the LED lamp beads 10 passes through the panel through holes 20 and protrudes on the top surface of the panel 2. At this time, the anti-glare structure on the panel 2 is as follows: baffles 3 are also provided between adjacent rows or columns of panel through holes 20 on the panel 2. The baffles 3 separate the plurality of LED lamp beads 10 into rows or columns of LED lamp beads. The height of the baffles 3 is not lower than the height of the LED lamp beads 10 passing through the panel 2, that is to say, the height of the baffles 3 is slightly higher than the height of the LED lamp beads 10 protruding from the panel 2, so as to separate adjacent two LED lamp beads 10 and reduce the mutual influence between the LED lamp beads 10. A plurality of first notches 30 are arranged at intervals on the top surface of the baffles 3. The first notches 30 are arranged at intervals along the length direction of the baffles 3. The light directly coming from the outside can also be scattered multiple times through the first notches 30 to disperse the light and reduce its intensity. Second notches 31 are arranged at the positions corresponding to adjacent rows or columns of LED lamp beads 10 on the top surface of the baffles 3. The depth of the second notches 31 is greater than the depth of the first notches 30, and the bottom end of the second notches 31 is lower than the top end of the LED lamp beads 10. In this way, while ensuring the normal display of the display screen, the mutual influence between adjacent rows or columns of LED lamp beads 10 can be reduced. Both the first notches 30 and the second notches 31 are notches with an inverted trapezoidal structure. On the premise of ensuring the structural strength of the baffles 3, it is also convenient for the emission of light from the LED lamp beads 10. A plurality of strip-shaped protrusions 4 with a triangular cross-section and parallel to the baffles 3 are also arranged around each panel through hole 20 on the top surface of the panel 2. That is to say, the strip-shaped protrusions 4 extend along the length direction of the baffles 3. Each strip-shaped protrusion 4 is parallel to the baffles 3. The strip-shaped protrusions 4 surround the panel through holes 20. Tooth-like structures are formed between the plurality of strip-shaped protrusions 4. The triangular cross-section of the strip-shaped protrusions 4 enables the light directly coming from the outside to be scattered multiple times when hitting the inclined surface of the strip-shaped protrusions 4, dispersing the light and reducing the light intensity, so as to achieve the purpose of anti-glare.At this time, the LED lamp bead 10 protrudes from the top surface of the strip-shaped protrusion 4, that is, the upper part of the LED lamp bead 10 passes through the panel through-hole 20 and then protrudes from the top surface of the strip-shaped protrusion 4. That is to say, the strip-shaped protrusion 4 surrounds the middle part of the LED lamp bead 10, and the strip-shaped protrusion 4 will not affect the light emission of the LED lamp bead 10; at the same time, a V-shaped groove 40 is formed between two adjacent strip-shaped protrusions 4 along the direction perpendicular to the baffle 3 among the multiple strip-shaped protrusions 4 corresponding to the same panel through-hole 20. That is to say, the strip-shaped protrusions 40 are connected end to end in sequence from the end adjacent to the baffle 3 to the end far from the baffle 3, and a V-shaped groove 40 is formed between two adjacent strip-shaped protrusions 4 in this direction.;

[0024] Further improvements, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown in, a third notch 41 is provided between the strip-shaped protrusions 4 corresponding to two adjacent panel through-holes 20 in the same row or the same column. In this way, the strip-shaped protrusions 4 in the same row or the same column are separated into strip-shaped protrusions with shorter lengths, and an LED lamp bead unit is formed corresponding to each panel through-hole 20, further scattering the light directly coming from the outside, further reducing the glare intensity, and improving the anti-glare effect.

[0025] Further improvements, such as Figure 3 and Figure 6 As shown in, mounting grooves 5 are provided at the edges of the opposite two sides of the bottom surface of the display screen body 1, and a connecting member 6 can be detachably mounted in any one or two of the mounting grooves 5. Two connecting member protrusions 60 that can be matched and engaged in the mounting groove 5 are arranged side by side and at intervals on the connecting member 6. Through the connecting member 6, two display screen bodies 1 can be connected and assembled, and then a display screen with a larger screen can be formed; during assembly, one connecting member protrusion 60 on the connecting member 6 is correspondingly engaged in the mounting groove 5 on one side of a display screen body 1, and the other connecting member protrusion 60 on the connecting member 6 is located outside the display screen body 1. Then, the connecting member 6 is fixed on the display screen body 1 by using screws. After that, the other connecting member protrusion 60 on the connecting member 6 is engaged and installed in the mounting groove 5 on one side of another display screen body 1, and the connecting member 6 is fixed on the other display screen body 1 by using screws. Further improvement, a protrusion through-hole 61 that penetrates the upper and lower surfaces of the connecting member protrusion 60 and the connecting member 6 is provided on the connecting member protrusion 60. In this way, when the connecting member 6 is installed on a display screen body 1, on the one hand, the display screen body 1 can be lifted by using it, and on the other hand, it will not cause the assembled display screen to have an overly thick backplane at the mounting groove 5 and affect its heat dissipation.

[0026] Further improvements, such as Figure 3As shown in the figure, a handle 7 is also provided in the middle of the bottom surface of the display screen body 1. The provision of the handle 7 enables the display screen body 1 to be lifted conveniently, facilitating its handling.

[0027] Although the present utility model has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it based on the present utility model, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model fall within the scope of protection required by the present utility model.
