In addition, the terms "first", "second", "third" and the like are only used for differentiation in description, and cannot be understood as indicating or implying relative importance. In the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more.

[0037] In the description of the utility model, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0038] The embodiments of the utility model will be described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as a limitation on the utility model.

[0039] In order to improve the structural strength of the mask and facilitate the large-screen display after the LED display screen is spliced and combined, the embodiments provide a mask and an LED display screen, which will be described below in combination with Figures 1 to 4The specific content of this embodiment will be described in detail. The first direction mentioned in this embodiment is the X direction, and the second direction mentioned in this embodiment is the Y direction.

[0040] like Figure 1 Combination Figure 2 As shown, the face mask 100 in this embodiment includes a face mask body 1, light-transmitting holes 2, a brim assembly, and a reinforcing assembly. Multiple light-transmitting holes 2 are disposed through the face mask body 1, allowing light from the LED light-emitting element 2001 to escape through them. The brim assembly includes a first brim 3 extending along a first direction, disposed on the face mask body 1 and located above the light-transmitting holes 2. The reinforcing assembly includes first reinforcing ribs 4 and second reinforcing ribs 5. Multiple first reinforcing ribs 4 are spaced apart on the left side of each light-transmitting hole 2, and multiple second reinforcing ribs 5 are spaced apart on the right side of each light-transmitting hole 2. Both the first reinforcing ribs 4 and the second reinforcing ribs 5 extend along a second direction.

[0041] In short, the mask 100 provided by this utility model has multiple light-transmitting holes 2 on the mask body 1 for emitting light from the LED light-emitting element 2001. A first brim 3 extending along a first direction is provided above each light-transmitting hole 2, which can block rainwater or sunlight from above the light-transmitting hole 2. By installing multiple first reinforcing ribs 4 on the left side and multiple second reinforcing ribs 5 on the right side of the light-transmitting hole 2, the overall structural strength of the mask 100 is improved, which is helpful for large-area assembly of the LED display screen. Since both the first reinforcing ribs 4 and the second reinforcing ribs 5 extend along a second direction, rainwater can be quickly drained downwards, avoiding water accumulation. When two masks 100 are spliced ​​together, a black line extending along the second direction is generated between the two masks 100 due to the gap. Since a black line is also formed between adjacent reinforcing ribs, the overall abrupt appearance of the mask 100 can be reduced, improving the visual appeal of the LED display screen.

[0042] Furthermore, the top of the first brim 3 is provided with a plurality of first arc-shaped surfaces 31 along the first direction. The plurality of first arc-shaped surfaces 31 on the top of the first brim 3 are connected in sequence to form a wave surface, which facilitates the scattering of external light and reduces the impact on the light parameters of the LED light-emitting element 2001.

[0043] Furthermore, the top of the first reinforcing rib 4 is provided with a second arc-shaped surface 41, and / or the top of the second reinforcing rib 5 is provided with a third arc-shaped surface 51. The second arc-shaped surfaces 41 on the top of multiple first reinforcing ribs 4 are connected in sequence to form a wave-like surface, and the third arc-shaped surfaces 51 on the top of multiple second reinforcing ribs 5 are connected in sequence to form a wave-like surface, which serves to both scatter sunlight and improve the aesthetics of the mask 100.

[0044] Further, the height of the plurality of first reinforcing ribs 4 protruding relative to the mask body 1 gradually increases in a direction away from the light transmission hole 2; and / or the height of the plurality of second reinforcing ribs 5 protruding relative to the mask body 1 gradually increases in a direction away from the light transmission hole 2. The first reinforcing ribs 4 and the second reinforcing ribs 5 can also shield sunlight and dust, and facilitate increasing the light-emitting angle of the LED light-emitting piece 2001.

[0045] Further, the brim assembly further includes a second brim 6 extending in the first direction, and the second brim 6 is arranged on the mask body 1 and located below the light transmission hole 2. By additionally arranging the second brim 6, rainwater or sunlight from below the light transmission hole 2 can be shielded. Optionally, the top of the second brim 6 is provided with a fourth arc surface 61.

[0046] Further, the height of the first brim 3 protruding relative to the mask body 1 is greater than the height of the second brim 6 protruding relative to the mask body 1. Since the height of the second brim 6 is less than the height of the first brim 3, the second brim 6 does not block the view of the audience.

[0047] Further, the reinforcing assembly further includes third reinforcing ribs 7, and the plurality of third reinforcing ribs 7 are arranged on the mask body 1 and located between the light transmission hole 2 and the second brim 6, and the third reinforcing ribs 7 extend in the second direction. By additionally arranging the third reinforcing ribs 7, the structural strength of the mask body 1 is further improved.

[0048] Further, the mask 100 further includes a plurality of connecting holes 8, and the connecting holes 8 are arranged through the mask body 1. By using fasteners such as screws or bolts to pass through the connecting holes 8, the mask 100 can be mounted and fixed on the PCB board 200 or a mounting frame or the like.

[0049] Further, the brim assembly further includes a plurality of third brims 9, and the third brims 9 are arranged on the mask body 1 and located at the periphery of the connecting holes 8. The third brims 9 shield the reflection of metal parts such as screws or bolts, thereby improving the display quality of the LED display screen.

[0050] As shown in Figure 3 In combination Figure 4 As shown in the accompanying drawings, the present embodiment also provides an LED display screen, which includes a PCB board 200 having a plurality of LED light-emitting pieces 2001 and the above-mentioned mask 100. The mask 100 is arranged on the PCB board 200, the LED light-emitting piece 2001 is located in the light transmission hole 2, and the mask 100 has high structural strength, which is conducive to large-screen display after the LED display screen is spliced and combined.
