DETAILED DESCRIPTION

[0032] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The following is combined with Figures 1 to 10 And specific embodiments discuss the present invention in detail.

[0034] like Figures 1 to 9 As shown, the utility model provides a display screen module, including a bottom shell 1, a lamp board 2 and a mask 3 arranged in sequence, the mask 3 including a first surface 31 opposite to the light board 2 and a second surface 32 away from the light board; a plurality of lamp bead holes 33 are provided on the mask 3, which pass through the first surface 31 and the second surface 32, and a plurality of lamp beads 21 are provided on the lamp board 2, which extend from the lamp bead holes 33 to the outside of the mask 3, and a brim structure 34 is provided on the outside of the lamp bead holes 33 on the second surface 32, and at least one brim structure 34 is provided on the outside of each lamp bead hole 33, and a serrated or arc-shaped groove 341 is provided on at least one brim structure 34 on the outside of each lamp bead hole 33. It is understood that this embodiment does not limit the number of brim structures 34 outside each lamp bead hole 33, and can be one or more. When the number of brim structures 34 is two or more, at least one of the brim structures 34 is provided with a serrated or arcuate groove 341, and the serrated or arcuate grooves are arranged along the length of the brim structure 34. In this embodiment, the brim structure 34 outside each lamp bead hole 33 can enhance the protection of the mask 3 for the lamp bead 21, resisting the impact of direct sunlight on the display effect of the display module. At the same time, the serrated or arcuate grooves 341 provided on the brim structure 34 can improve the appearance of moiré on the display screen. That is, the serrated or arcuate grooves 341 can weaken the periodicity of the pixel structure, thereby reducing the appearance of moiré. It is understood that moiré is generally caused by interference between the LED pixel arrangement and the perception of the observer (or camera). When two or more different grid structures (such as the LED pixel arrangement and the pixel arrangement of the camera sensor) overlap at similar frequencies, moiré is generated. However, the present application can interrupt this regular network-like overlap by providing serrated or arc-shaped grooves on the brim structure 34, so that the interference phenomenon is weakened or eliminated.

[0035] It should be noted that the shape of the brim structure 34 is not limited, which can be adapted to the shape of the lamp bead 21. For example, if the lamp bead 21 is square, the brim structure 34 can be arranged on the left side, the right side, the upper side, the lower side, or three of the above sides of the lamp bead 21, as long as it does not affect the function of the lamp bead 21 itself. The brim structure 34 of the present application refers to a protruding part protruding from the mask 3 and extending outward for a distance. When the lamp bead 21 is square, the brim structure 34 is a strip-shaped protruding part. When the lamp bead 21 is circular, the brim structure 34 is an arc-shaped protruding part. The brim structure 34 in the embodiment needs to surround the lamp bead 21 to a certain extent.

[0036] By arranging the brim structure 34 outside the lamp bead hole 33 and arranging the sawtooth-shaped and arc-shaped grooves 341 on the brim structure 34, the present application can reduce moire, environmental reflection, glare and other visual disturbances, making the display screen module more suitable for outdoor environments, and at the same time, the service life of the display screen module can be improved.

[0037] Referring to Figure 2 and Figure 3 , in at least some embodiments, the brim structure 34 is in a conical structure, that is, it is a tapered structure outward from the second surface 32 of the mask 3. The small end of the conical structure is away from the mask 3, and the large end of the conical structure is close to the mask 3. The brim structure 34 in the embodiment of the present application does not need to be too thick, as long as it can achieve the protection of the lamp bead 21 and improve the moire. The brim structure 34 designed in the present application is a conical structure, which can reduce the use of materials, reduce the weight of the display screen, and at the same time, it can also reduce the occupation of the space around the lamp bead 21, avoid blocking the light of the lamp bead 21, and affect the lighting effect.

[0038] In some embodiments, the lamp bead hole 33 is a square hole. A plurality of square holes are arranged in the horizontal direction (i.e. the X-axis direction in Figure 2 ) and the vertical direction (i.e. the Y-axis direction in Figure 2 ). The opposite sides of each square hole in the horizontal direction are respectively provided with a first brim structure 35 and a second brim structure 36. The first brim structure 35 is provided with a sawtooth-shaped or arc-shaped groove 341, and the second brim structure 351 is not provided with a sawtooth-shaped or arc-shaped groove, or the first brim structure 35 is not provided with a sawtooth-shaped or arc-shaped groove, and the second brim structure 36 is provided with a sawtooth-shaped or arc-shaped groove, or both the first brim structure 35 and the second brim structure 36 are provided with a sawtooth-shaped or arc-shaped groove. In the present application, there is an adjacent first brim structure 34 and a second brim structure 35 between two adjacent lamp bead holes 33 in the horizontal direction, that is, the brim structures outside each lamp bead hole 33 are not shared. Of course, in other embodiments, the brim structures between two adjacent lamp bead holes 33 can also be shared.

[0039] It should be noted that the horizontal direction in the present application refers to the X-axis direction in Figure 2The X-axis direction in the vertical direction is Figure 2 In addition, the arrangement of the lamp beads 21 and the brim structure 34 in the embodiment of the present application is arranged in a certain regular pattern. If in other embodiments, the arrangement of the lamp beads 21 and the brim structure 34 has no specific rules, it also falls within the scope of protection of the present application, as long as the purpose of protecting the lamp beads 21 is achieved.

[0040] In some embodiments, to avoid affecting the viewing angle of the lamp beads, the first brim structure 35 and the second brim structure 36 have different heights. If a person is viewing the display screen from the bottom up, the brim structure located above the lamp beads 21 is relatively high, so that the brim structure does not affect the viewing angle of the lamp beads 21. Of course, in other embodiments, the height of the brim structure can be adjusted accordingly to the viewing angle of different lamp beads.

[0041] See Figure 4 and Figure 5 In some embodiments, grooves 37 are provided on the first surface 31 at positions opposite the first brim structure 35 and the second brim structure 36. The size of grooves 37 is adapted to the brim structure. When the brim structure is a strip-shaped structure, grooves 37 are also strip-shaped grooves. Grooves 37 are also located next to the lamp bead holes 33. Their function is to reduce the material used in the brim structure 34, ensure uniform material use throughout the mask 3, and maintain consistent strength. The present embodiment does not limit the depth, shape, or size of grooves 37. The purpose of providing grooves 37 is to reduce material use and the weight of the LED display without reducing strength, thereby saving costs.

[0042] See Figure 6 In some embodiments, an arched reinforcement structure 11 is provided on the surface of the bottom shell 1 opposite to the light board 2. The arched reinforcement structure 11 is located around the bottom shell 1. The arched reinforcement structure 11 is superior to the flat structure and can improve the strength of the display screen module. Specifically, when pressure is applied to the arched reinforcement structure 11, the pressure is decomposed and transmitted to the planar structure of the bottom shell 1 through the arched reinforcement structure 11, thereby reducing the force on the bottom shell 1 and increasing the overall strength of the bottom shell 1.

[0043] In some embodiments, heat dissipation holes (not shown in the figure) are provided on the side of the bottom shell 1 to enhance the heat dissipation function of the display screen module, improve heat dissipation, and increase the service life of the module.

As can be seen from the above, the mask support 4 is clamped between the bottom shell 1 and the lamp plate 2, and the bottom shell 1 is directly connected with the lamp plate 2, so that more fixing holes are avoided to be machined on the bottom shell 1, and the production efficiency of the bottom shell 1 is increased.

[0045] In some embodiments, the mask support 4 is provided with a second protruding column 41 facing the mask 3, the second protruding column 41 is provided with a second threaded hole, the lamp plate 2 is provided with a through hole corresponding to the second protruding column 41, the mask 3 is provided with a second connecting hole 38 at a position opposite to the second protruding column 41, and a second connecting piece is locked in the second threaded hole after passing through the second connecting hole 38. The bottom shell 1 of the present application is made of metal, and through the above connecting mode, on the one hand, more fixing holes are avoided to be machined, and the production efficiency of the bottom shell 1 is increased, and on the other hand, by contacting the lamp plate 2 with the mask support 4, the flatness of the display screen module can be controlled by controlling the flatness of the mask support 4, so that the display module is not affected by the unevenness of the internal contact surface of the bottom shell 1, and the influence of the unevenness of the bottom shell 1 on the display surface does not need to be considered. In addition, the mask support 4 of the present application is made of PC material, and the bottom shell 1 is made of metal, and the two are matched, so that the display screen module has the advantages of high strength, small deformation, high precision control, low cost and the like.
