[0030] The utility model provides a display screen mask, which is used for an LED display screen.

[0031] In the embodiment of the present utility model, Figures 1 to 4 As shown, the display screen mask comprises a mask body 10 and a handle rib.

[0032] Specifically, the mask body 10 has a mounting surface 12 and a display surface 13 opposite to each other, and the mask body 10 is provided with a plurality of mounting holes 11, each mounting hole 11 penetrates the mounting surface 12 and the display surface 13, any two adjacent mounting holes 11 are spaced apart from each other, and the size of each mounting hole 11 is gradually reduced in the direction close to the display surface 13. A plurality of convex ribs are provided on the display surface 13, and one convex rib is provided corresponding to the periphery of one mounting hole 11.

[0033] A plurality of mounting holes 11 are arranged in a matrix on the mask body 10, and any two adjacent mounting holes 11 are spaced apart from each other. The shape of the mounting hole 11 is the same as the shape of the LED lamp bead. For example, when the LED lamp bead is a cylinder, the shape of the mounting hole 11 is a round hole, and when the LED lamp bead is a rectangular parallelepiped, the shape of the mounting hole 11 is a square hole. The diameter of one end of the mounting hole 11 close to the mounting surface 12 is larger than the diameter of the other end close to the display surface 13.

[0034] The convex ribs arranged on the display surface 13 can absorb and diffusely reflect ambient light, thereby reducing glare and improving the display effect.

[0035] During installation, the mounting surface 12 of the mask body 10 faces the LED lamp bead, and then the mask body 10 is driven to move in the direction of the LED lamp bead so that the LED lamp bead extends into the mounting hole 11. As the mask body 10 continues to move, the distance between the side wall of the LED lamp bead and the hole wall of the mounting hole 11 is continuously reduced until they are tightly pressed together. At this time, the side wall of the LED lamp bead can fit the hole wall of the mounting hole 11. In this way, when it rains, rainwater cannot flow from the mounting hole 11 to the display screen body, and dust, flying insects, etc. cannot enter from the mounting hole 11, which improves the waterproofness of the display screen mask while ensuring the installation stability of the mask body 10. Setting the side with a larger aperture of the mounting hole 11 as the installation side can also reduce the difficulty of installing the mask body 10.

[0036] The technical solution of the utility model is to set a plurality of mounting holes 11 on the mask body 10, each mounting hole 11 penetrates the mounting surface 12 and the display surface 13 of the mask body 10, and the size of each mounting hole 11 is gradually reduced in the direction close to the display surface 13. In this way, during installation, the LED lamp bead extends into the mounting hole 11 from one side of the mounting surface 12 of the mask body 10, and as the mask body 10 moves toward the display screen body, the distance between the side wall of the LED lamp bead and the hole wall of the mounting hole 11 is gradually reduced until the side wall of the LED lamp bead is tightly against the hole wall of the mounting hole 11, even if the side wall of the LED lamp bead can fit with the hole wall of the mounting hole 11, in this way, when it rains, rainwater cannot flow from the mounting hole 11 to the display screen body, and dust, flying insects, etc. cannot enter from the mounting hole 11, thereby improving the waterproofness of the display screen mask.

[0037] In some embodiments, the hole wall of the mounting hole 11 is provided with a flexible layer, and the flexible layer extends along the circumference of the mask body 10. Specifically, during installation, the flexible layer can increase the friction between the hole wall of the mounting hole 11 and the LED lamp bead, which can improve the installation stability of the mask body 10. At the same time, it can also achieve seamless fit when the hole wall of the mounting hole 11 abuts against the side wall of the LED lamp bead. Such a setting is conducive to further improving the dustproof and waterproof effect. Among them, the flexible layer can be but not limited to rubber, silicone, etc., and can be selected according to actual conditions. Of course, in other embodiments, the hole wall of the mounting hole 11 may not be provided with a flexible layer.

[0038] In some embodiments, each convex rib is arranged around the mounting hole 11. That is, the convex rib surrounds the periphery of the mounting hole 11. Such an arrangement enables the convex rib to absorb light from the LED lamp beads in multiple directions, which is beneficial to further improve the display effect. Of course, in other embodiments, the convex rib can also be arranged only on one side of the periphery of the mounting hole 11.

[0039] In some embodiments, a light-transmitting hole is formed between the inner walls of the ribs, and the light-transmitting hole is connected to the mounting hole 11. The size of the mounting hole 11 is gradually expanded in the direction away from the mounting hole 11. Such a setting can increase the display area of ​​the LED lamp bead, which is conducive to improving the display effect. Of course, in other embodiments, the size of the light-transmitting hole in the direction away from the mounting hole 11 is the same as the size in the direction close to the mounting hole 11.

[0040] In some embodiments, the ribs around any two adjacent mounting holes 11 are arranged at intervals. In this way, the gap between the two adjacent ribs can be used to absorb light, thereby reducing the light reflection on the outer surface of the cover body, which can further improve the display effect. Of course, in other embodiments, crisscross ribs can also be arranged on the outer surface of the cover body.

[0041] In some embodiments, a pattern layer is laid on the side of the convex ribs facing away from the display surface 13 , and the pattern layers on several convex ribs are combined to form a large pattern.

[0042] Specifically, each convex rib is paved with a small pattern, and a plurality of small patterns are combined to form a preset large pattern, so that after the LED display screen is turned off, it can be displayed by laying the pattern layer on the convex rib, so as to avoid the LED display screen being a whole black screen after being turned off, resulting in a large difference between the LED display screen and the surrounding environment, and appearing abrupt, which is conducive to improving the functionality and user experience of the display screen mask. Of course, in other embodiments, the pattern layer may not be set on the convex rib.

[0043] Furthermore, the pattern layer is covered with a transparent waterproof layer. In this way, the display of the pattern layer will not be affected, and the transparent waterproof layer can also protect the pattern layer and extend the display life of the pattern layer. Optionally, the transparent waterproof layer is formed by spraying an anti-ultraviolet coating.

[0044] In some embodiments, a plurality of arc surfaces are provided on the side of the convex rib away from the display surface 13, and the plurality of arc surfaces are distributed along the circumference of the mounting hole 11, and each arc surface is provided with a pattern layer. Optionally, the arc surface is a concave arc surface. In this way, the top of the convex rib can be roughly in a wave structure, which is conducive to further reducing the light reflection on the outer surface of the display screen mask and further improving the display effect. Of course, in other embodiments, the arc surface can also be a convex arc surface.

[0045] In some embodiments, the mask body 10 includes a plurality of mask bodies, which are spliced ​​together to form the mask body 10, each mask body is provided with a mounting hole 11, and a plurality of ribs are arranged in one-to-one correspondence with the plurality of mask bodies.

[0046] Specifically, during the production process, a preset pattern is generally designed according to the shape and size of the display screen body. After the preset pattern is determined, the preset pattern is divided into several small patterns according to the shape and size of the display screen body, and several small patterns are combined to form the preset pattern. Compared with the method of directly laying a whole pattern, this method is conducive to reducing the difficulty of setting.

[0047] The utility model also proposes an LED display screen, which includes a display screen body and a display screen mask. The specific structure of the display screen mask refers to the above-mentioned embodiment. Since the LED display screen adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here. Among them, the display screen mask is installed at the LED lamp beads on the display screen body, and the LED lamp beads extend into the mounting holes 11 and are exposed from the mounting holes 11 on the display screen mask, and the side of the LED lamp beads abuts against the hole wall of the mounting hole 11. The display screen body can be a straight screen, a curved screen or a special-shaped screen, which can be set according to the needs.

[0048] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
