Specific embodiment

In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain The utility model, is not used to limit the utility model.

It should be noted that when element is referred to as " being fixed on " or " being arranged at " another element, it can be directly another On one element or it is connected on another element.When an element is known as " being connected to " another element, it can To be directly to another element or be indirectly connected on another element.

Also, it should be noted that the orientation term such as left and right, upper and lower in the present embodiment, be only each other relative concept or Normal operating condition with product is reference, and be should not be regarded as restrictive.

The advantages of LED display is with its high-resolution, high brightness, has been widely used for indoor and outdoor word, video and throws Shadow.

As depicted in figs. 1 and 2, a kind of LED display mask is present embodiments provided, mask 100 has multiple accommodating LED The through hole 101 that lamp 200 is passed through a, side end face of mask 100 is connected with LED lamp panel 300, and mask 100 is metal mask 100, gold Another side end face for belonging to mask 100 is provided with sub- black film layer 102.

In the present embodiment, as shown in Fig. 2 the one side of metal mask 100 refers to the lower surface of metal mask 100, metal Another side end face of mask 100 refers to the upper surface of metal mask.In the present embodiment, mask 100 is metal material, in high temperature and Any smog and toxic gas will not be discharged under the barbecue of flame, safety non-toxic and fire prevention is used.Metal material Surface is usually silver color, with metallic luster, easily forms reflected light, causes glare phenomenon, reduces the contrast of LED display Degree.Sub- black film layer 102 is covered in the upper surface of metal mask 100, can efficiently reduce the reflected light of metal mask 100, increases Plus the contrast of LED display.Therefore, the metal mask 100 of the present embodiment can be by Britain BS476 construction materials and component Flammability test, with fire protecting performance higher, the contrast of LED display can be increased again.

Specifically, metal mask 100 can be made by techniques such as oil spout, baking vanish, black anodizing, electrophoresis, vacuum coatings Upper surface be coated with one layer of sub- black film layer 102, to cover metal metallic luster in itself, reduce reflected light, lifting LED shows The contrast of display screen.

In the present embodiment, if the upper surface of metal mask 100 coats sub- black film layer 102, there is part area The side wall of domain such as through hole 101 forms reflected light.As shown in figure 3, the outer surface of the preferred metal mask 100 of the present embodiment is provided with Sub- black film layer 102, makes sub- black film layer 102 that the outer surface of metal mask 100 is completely covered, and reflection light is completely eliminated.

Alternatively, sub- black film layer 102 is sub- black insulating barrier.Have many electronic components, electronics in LED lamp panel 300 Part metals part on element exposes, and is easily contacted with metal mask 100, influences the performance of LED lamp panel 300.Such as LED 200, when especially SMD LED 200 is welded with LED lamp panel 300, solder joint 201 is exposed to outside LED 200, pole It is easily caused metal mask 100 to be contacted with solder joint, metal mask 100 is likely to be contacted with the stitch of LED 200 in addition.Work as metal When mask 100 is contacted with the stitch of solder joint 201 or LED 200, it is most likely that cause the short circuit of LED 200, influence LED shows The normal of screen is used.Therefore, in the present embodiment, sub- black film layer 102 is sub- black insulating barrier, so that the table of metal mask 100 Insulate in face.It is acrylic resin paint or Al that the present embodiment Central Asia black film layer 102 can be₂O₃The film layer of material, also may be used The superposition of the tunic of the above material.

Alternatively, microgroove layer 103 is provided between metal mask 100 and sub- black film layer 102, microgroove layer 103 is one layer Rough fine structure, increases the surface roughness of metal mask 100, and sub- black film layer 102 is attached to metal mask 100 During surface, the roughness of sub- black film layer 102 is increased, more efficiently reduce reflected light.In addition, microgroove layer 103 can increase Plus sub- black film layer 102 and the contact area of metal mask 100, make the attachment of sub- black film layer 102 more firm.It is no matter sub- black Color film layer 102 is covered in the upper surface of metal mask 100 or sub- black film layer 102 is covered in and metal mask 100 is completely covered Outer surface, metal mask 100 can be set microgroove layer 103 with sub- black film layer 102, with identical beneficial effect.

Specifically, to have etching layer or frosted layer, etching layer is by punch forming, laser cutting, carving to microgroove layer 103 In the Surface Machining of metal mask 200 is formed, frosted layer is to be made by way of mechanical grinding to the modes such as quarter, electric spark, CNC Form frosted layer.

Alternatively, the lower surface of metal mask 100 is provided with the mucigel 104 for being connected with LED lamp panel 300.This reality In applying example, can also by the modes such as double faced adhesive tape, glue spraying, threaded connection, riveting, welding make metal mask 200 entirely with LED Lamp plate 300 is assembled.

Alternatively, the rectangular array of through hole 101 distribution, the shape of through hole 101 can be circular hole or square hole.

The present embodiment additionally provides a kind of LED display, as shown in figure 4, including LED lamp panel 300, being fixed on LED lamp panel LED 200 and metal mask 100 on 300.

The lower surface of metal mask 100 is laid in LED lamp panel 300, and LED 200 passes through through hole 101.LED 200 is in Rectangular array is distributed in LED lamp panel, and the rectangular array of LED 200 is identical with the rectangular array of metal mask 100, and LED 200 are of similar shape with metal mask 200.

In the present embodiment, the mask of conventional plastic material is replaced with the metal mask 200 with sub- black film layer 102, Can effectively avoid discharging smog and harmful poison gas under the barbecue of high temperature or flame, make again LED display have compared with Contrast high.

Preferred embodiment of the present utility model is these are only, is not used to limit the utility model, it is all in this practicality Any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model Within the scope of shield.
