The utility model adopts the technical proposal that: a face mask of an LED display screen comprises a face mask body and a plurality of grid surrounding walls, wherein the grid surrounding walls are arranged on the upper surface of the face mask body at equal intervals in a longitudinal and transverse mode; the grid enclosure wall is formed by four side walls in an enclosing mode, every two adjacent side walls are perpendicular to each other, a column is formed at the intersection of the two side walls, the top surface of the column is a plane, and the top surface of the side wall between the two columns is sunken from two sides to the middle to form a cambered surface.

Preferably, the height of the side wall is 0.45-0.6 mm.

Preferably, the height difference of the cambered surfaces is 0.25-0.35 mm.

Preferably, the outer side of the side wall is inclined outwardly from the top end to the bottom end.

Preferably, the inner side surface of the side wall is inclined toward the lamp hole from the top end to the bottom end.

Preferably, the lower surface of the mask body is provided with a step opening along the edge of the lamp hole.

Preferably, the mask body is provided with a screw hole.

Preferably, the screw hole is located at the intersection of the transverse groove and the longitudinal groove.

The utility model has the advantages that: compared with the prior art, the utility model discloses intersection between the both sides wall forms a pillar, the top surface that the lateral wall is located between two pillars is the cambered surface, and cooperate the horizontal groove and erect the groove structure, when people see the face guard body, the entity formation of image of reflecting back people's eyes can make the luminance of the cambered surface that is close to the pillar darker, luminance in the middle of pillar and the cambered surface is brighter, thus, can effectively weaken equidistant vertical and horizontal grid leg's the overall structure's of grid leg itself overall structure who is in the same place, and then the visual effect of one grid leg that can effectual desalination, strengthen the display effect of LED display screen LED lamp.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are only some sub-embodiments of the present invention. Based on the embodiments in the present invention, other embodiments obtained by the skilled in the art without creative work all belong to the protection scope of the present invention.

Referring to fig. 1-4, in the embodiment of the present invention, a LED display screen mask comprises a mask body 1 and a plurality of grid walls 2, a plurality of grid walls 2 are arranged on the upper surface of the mask body 1 at equal intervals, a plurality of transverse grooves 5 and longitudinal grooves 4 are formed between the grid walls, and the grid walls 2 form lamp holes 3 penetrating through the mask body 1. The grid surrounding wall 2 is formed by surrounding four side walls 21, every two adjacent side walls 21 are perpendicular to each other, a column 22 is formed at the intersection between the two side walls 21, the top surface of the column 22 is a plane, and the top surface of the side wall 21 between the two columns 22 is recessed from two sides to the middle to form an arc surface 23.

The utility model discloses in grid leg 2, intersection between both sides wall 21 forms a pillar 22, top surface that lateral wall 21 is located between two pillars 22 is cambered surface 23, and cooperate horizontal groove 5 and erect groove 4 structure, when people see face guard body 1, the entity formation of image of reflection back people's eyes can make the luminance of the cambered surface 23 that is close to pillar 22 darker, luminance in the middle of pillar 22 and cambered surface 23 is brighter, thus, can effectively weaken equidistant grid leg 2 the overall structure's of itself overall structure who is in the same place of indulging horizontally visual effect, and then can be effectual the visual effect of a grid lattice leg 2 of desalination, strengthen the display effect of LED display screen LED lamp.

In some embodiments, for better and effective visual effect of desalting the one-lattice-one-grating lattice surrounding wall 2, the utility model discloses a deeper transverse groove 5 and vertical groove 4 are adopted, the height of the lateral wall 21 is 0.45-0.6mm, namely the deepest depth of the transverse groove 5 and vertical groove 4 is 0.45-0.6mm, the height difference of the cambered surface 23 is 0.25-0.35 mm. In another embodiment, in order to further reduce the visual effect of the grid surrounding wall 2, the outer side surface of the sidewall 21 is inclined outward from the top end to the bottom end, and the inner side surface of the sidewall 21 is inclined toward the lamp hole from the top end to the bottom end.
