[0002] With the continuous advancement of LED display technology, its application in various scenarios such as advertising, stage, and conference is becoming more and more extensive.
[0003] In order to ensure the stable operation of LED lamp beads and extend their service life, it is usually necessary to set a mask to protect the LED lamp beads. The mask not only protects the LED lamp beads from the external environment, but also effectively blocks the solder pins and solder paste of the LED lamp beads, improving the overall aesthetics and reliability of the display.
[0004] In the traditional design of LED display screen masks, in order to adjust the visual range of the LED display screen, such as blocking the light emitted by the LED display screen in a certain direction, a brim structure with an inclined angle is often integrated. However, when a certain angle is formed between the brim and the mask, it often makes it extremely difficult to demold the mask during the one-piece injection molding process. This may eventually lead to warping of the finished product, which in turn affects the display effect and overall quality of the LED display screen. Utility Model Content

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0034] Example 1
[0035] Combination Figures 1 to 6 As shown, the display screen mask of the utility model is schematically shown, including a shell 10 and a shielding component 20. The shell 10 can be detachably connected to the light board by existing screws, bolts, buckles and other parts. The shell 10 has a mounting surface 11 and a fixing surface arranged back to back, and the fixing surface is directly or indirectly attached to the light board.
[0036] like Figure 3 and Figure 4 The shielding component 20 is detachably connected to the mounting surface 11 of the shell 10. Therefore, the shielding component 20 and the shell 10 can be produced by integral injection molding respectively, and then the two can be detachably connected, which can solve the problem of difficult demoulding and high mold cost caused by injection molding of the shielding component 20 and the shell 10 as an integral structure. Of course, the materials of the shielding component 20 and the shell 10 can be the same, or they can be made of different materials. For example, the shielding component 20 is made of magnesium-aluminum alloy, and the shell 10 is manufactured by integral injection molding. The shell 10 is large in size and uses a large amount of material. Therefore, the use of integral injection molding can effectively reduce material costs. The shielding component 20 plays a protective role. It is made of magnesium-aluminum alloy with high rigidity, which can effectively improve its protective performance.
[0037] The mounting surface 11 of the housing 10 is provided with a receiving structure 111 for arranging the lamp beads 51. The receiving structure 111 specifically includes a receiving hole opened on the mounting surface 11. The receiving hole is used to accommodate the lamp beads 51. The light-emitting end of the lamp beads 51 passes through the receiving hole and is located on one side of the mounting surface 11 of the housing 10, that is, the light emitted by the lamp beads 51 can be scattered on the mounting surface 11. The shielding component 20 is located on the side of the receiving structure 111, wherein part or all of the receiving structure 111 overlaps with the projection of the shielding component 20 on the mounting surface 11. Therefore, the shielding component 20 can not only block the light scattering of the lamp beads 51 in a certain direction to adjust the visible range of the display screen and reduce the stray light pollution in a certain direction, but also the shielding component 20 can shield the lamp beads 51 from rain. When the shell 10 is installed on the facade of a building, the shell 10 is perpendicular to the horizontal plane, the axis of the receiving hole is parallel to the horizontal plane, and the shielding component 20 is located above the receiving hole. Therefore, the shielding component 20 can shield the receiving hole and the lamp beads 51 therein from rain.
[0038] In this embodiment, if Figure 4There are multiple accommodating structures 111, which are arranged in a matrix to correspond to the lamp beads 51 arranged in a matrix. The shielding components 20 are arranged along the row or column direction of the matrix. When the shell 10 is installed on the facade of the building, the shielding components 20 are arranged along the row direction of the matrix, that is, the shielding components 20 are arranged parallel to the horizontal direction. Each row of accommodating structures 111 corresponds to a shielding component 20, and the shielding components 20 provide shielding and protection for the row of accommodating structures 111.
[0039] In order to detachably connect the housing 10 and the shielding member 20, Figure 3 As shown, the display screen mask further includes a connection assembly, which includes a snap-in block 21 and a snap-in groove 12 that are detachably connected, one of which is provided on the mounting surface 11, and the other is provided on the shielding component 20. In this embodiment, a snap-in block 21 is provided on one side of the shielding component 20, and a snap-in groove 12 is provided on the mounting surface 11, and the snap-in groove 12 is provided adjacent to the accommodating structure 111, wherein the number of the snap-in blocks 21 and the snap-in groove 12 is the same and both are provided in plurality, and each shielding component 20 is provided with a plurality of snap-in blocks 21, so that the shielding component 20 is stably connected to the housing 10.
[0040] Furthermore, the shielding component 20 includes a mounting member 22 and a shielding member 23 connected to each other. Figure 5 The mounting member 22 is provided with a clamping block 21, and the mounting member 22 is detachably connected to the mounting surface 11. The extending direction of the shielding member 23 is inclined to the mounting surface 11, that is, the shielding member 23 and the mounting member 22 are inclined to each other, which makes the cross-section of the shielding component 20 present an obtuse L-shape.
[0041] like Figure 5 and Figure 6 The shielding component 20 is provided with a plurality of first reflecting surfaces 24 arranged opposite to the accommodating structure 111. The first reflecting surfaces 24 are arranged obliquely to the mounting surface 11. An opening 30 for exposing the accommodating structure 111 to the outside is provided between the shielding component 20 and the shell 10. The first reflecting surfaces 24 are arranged to face away from the opening 30. The light emitted by the lamp beads 51 arranged in the accommodating structure 111 is reflected by the first reflecting surfaces 24 and then emitted toward the inner wall surface of the shielding component 20 or the mounting surface 11 of the shell 10, and then reflected by the inner wall surface of the shielding component 20 or the mounting surface 11 of the shell 10 to the outside of the opening 30, so as to maximize the use of the light emitted by the lamp beads 51. More preferably, the mounting surface 11 is provided with a second reflecting surface 112 adjacent to the accommodating structure 111. The second reflecting surface 112 and the first reflecting surface 24 are arranged opposite to each other, and the second reflecting surface 112 is arranged toward the opening 30. Light is emitted by the lamp bead 51 and is reflected by the first reflecting surface 24 and the second reflecting surface 112 in sequence to the outside of the opening 30. In this way, light can be emitted in a directionally-oriented manner, so that the audience perceives a higher brightness of the display screen.
[0042] In this embodiment, the angle between the first reflective surface 24 and the mounting surface 11 is smaller than the angle between the second reflective surface 112 and the mounting surface 11. A plurality of second reflective surfaces 112 are provided on both sides of each accommodating structure 111. In particular, on the mounting surface 11 of the housing 10, along the extending direction of the shielding component 20, the accommodating structures 111 and the second reflective surfaces 112 are alternately arranged.
[0043] In order to reflect more light emitted by the lamp beads 51, a plurality of first reflecting surfaces 24 are provided, and the plurality of first reflecting surfaces 24 are parallel to each other so that the cross-section of the shielding component 20 facing the side of the accommodating structure 111 is stepped, and the light can be reflected by each first reflecting surface 24 to the second reflecting surface 112.
[0044] In order to reduce the light transmittance of the shielding component 20 and suppress the light leakage of the shielding component 20, an ink layer is coated on the shielding component 20, and the ink layer is specifically coated on the outer wall surface and / or the inner wall surface of the shielding member 23.
[0045] Example 2
[0046] like Figure 7 In order to solve the same technical problem, the utility model also provides a display module, including a circuit board 50 and the above-mentioned display screen mask. Specifically, a plurality of lamp beads 51 arranged in a matrix are arranged on the circuit board 50, and a glue layer 40 is coated on the surface of the circuit board 50 on which the lamp beads 51 are arranged. The shell 10 is attached to the glue layer 40. The shell 10 and the circuit board 50 can be connected by existing screws or bolts. The lamp beads 51 pass through the accommodating holes of the shell 10 so that the light-emitting end of the lamp beads 51 is located on one side of the mounting surface 11 of the shell 10.
[0047] To summarize, the mounting surface 11 of the shell 10 is provided with a receiving structure 111 for receiving the lamp beads 51, the shielding component 20 is detachably connected to the mounting surface 11 and is located on the side of the receiving structure 111, part or all of the receiving structure 111 overlaps with the projection of the shielding component 20 on the mounting surface 11, the shielding component 20 can block the lamp beads 51 from scattering light in certain directions to adjust the visible range of the display screen, and the shielding component 20 can also shield the receiving structure 111 from rain, the shielding component 20 is detachably connected to the shell 10, so that the shell 10 and the shielding component 20 can be injection molded separately to avoid the difficulty of demolding, which is conducive to reducing the manufacturing cost of the display screen mask.
