Embodiment 1
As Figure 1-3, the present embodiment provides a kind of led display screen mask increasing visible angle, including mask originally
Body 1, mask body 1 is platy structure, and mask body 1 is provided with multiple regularly arranged through holes 3, and through hole 3 is used for and LED lamp
Pearl is socketed, and is provided with card contact (in figure does not mark) inside described through hole, so that led lamp beads 4 fixation is connected in through hole, realizes described
Led display screen mask and the connection of LED lamp plate 8；Compare by the way of mask is installed in punching, installing/dismounting is convenient.
The side of through hole 3 is surrounded by u shape curved surface 2, enables the visible angle of led display screen to reach more than 170 °.
The shape of through hole 3 is consistent with led lamp beads 4 profile, and in the present embodiment, through hole 3 is square, four sides of square through hole 3
While being respectively equipped with a u shape curved surface 2 to surround described through hole 3；And through hole 3 is more than the cross-sectional area of led lamp beads 4 so that through hole 3
Space is left between edge and the led lamp beads 4 being socketed in through hole 3；Can avoid there is friction between mask and led lamp beads 4, keep away
Exempt from mask friction damage led lamp beads 4, the installation effect of led lamp beads 4 can also be lifted simultaneously.
In the present embodiment, the rule of surface of mask body 1 is also uniformly placed with a plurality of transverse concave groove 6 and longitudinal fluting 7, horizontal
Staggered with longitudinal fluting 7 to groove 6, described transverse concave groove 6, the width of longitudinal fluting 7 are 0.2-0.4mm, and depth is
0.3-0.5mm.And vertical dimension d1 and adjacent two longitudinal fluting 7 centrage between the centrage of laterally adjacent two through hole 3 it
Between vertical dimension d2 equal；Vertical dimension d3 between the centrage of longitudinally adjacent two through hole 3 with adjacent two transverse concave grooves 6
Vertical dimension d4 between heart line is equal.
Additionally, the mask body 1 of square through hole 3 periphery of the present embodiment is provided with multiple salient points 5, described led display screen
Mask installs in the state of LED lamp plate, and the height sum of the thickness of mask body 1 and salient point 5 is more than the height of led lamp beads
Degree.
Salient point 5 is arranged in the mask body 1 of 3 four jiaos of square through hole.The height of the thickness of mask body 1 and salient point 5 it
With more than led lamp beads height 0.3mm-0.5mm.
It is additionally provided with anti-dazzle light oil reservoir, this anti-dazzle light oil reservoir can be sprayed on mask originally by injection mode in mask body 1
Body surface face, this anti-dazzle light oil reservoir also can play certain preventive effect to dazzle, improves the vision effect of led display screen further
Really.
As shown in Fig. 3,7-8, because the four side of the square through hole 3 on the present embodiment led display screen mask is by four u shapes
Curved surface surrounds, and mask can be avoided to stop the light that comes out of LED lamp, reduces the obstruct to light so that light can conventional four
Week dissipates, thus reaching the purpose increasing led display screen visible angle, in the present embodiment, led display screen mask can make led show
The visible angle of display screen reaches 170 °.The visible angle of lifting led display screen, can make audient face bigger.
Compared to existing technology, as shown in Fig. 4-6,9-10, it is not provided with the led display screen mask of u-shaped curved surface, the sending out of light
Dissipate and be substantially obstructed, divergence of beam angle is narrower, and the visible angle of therefore led display screen also have received restriction, and its visible angle is only
For 158.7 °, visible angle is relatively low.
Further, since the present embodiment arranges a plurality of transverse concave groove 6 and longitudinal fluting 7, transverse concave groove 6 He in mask body
The width of longitudinal fluting 7 is consistent with the splicing gap of mosaic display screen, can be effectively improved between splicing mask and mask
The splicing gap problem substantially uneven with absorption to the reflection of light, improves the globality of the picture of led display screen, and improves
The visual effect of people's viewing；And the transverse concave groove on mask and the staggered groove lines of longitudinal fluting, favourable mask
Absorption for light and diffuse-reflectance, also play the generation preventing dazzle to a certain extent.Usually, the spelling between splicing mask
Seam gap, between 0.2-0.4mm, therefore the width of transverse concave groove, longitudinal fluting is arranged between 0.2-0.4mm, can be relatively
Eliminate well light reflection and absorb uneven problem, preferably improve the picture globality of led display screen.
And, in the present embodiment by vertical dimension d1 between the centrage of two through hole 3 laterally adjacent on mask with adjacent
Vertical dimension d2 between two longitudinal fluting 7 centrage is arranged to equal, and by between the centrage of longitudinally adjacent two through hole 3
Vertical dimension d3 and adjacent two transverse concave groove 6 centrage between vertical dimension d4 be also configured to equal, also can preferably disappear
Except light reflects and absorbs uneven problem, thus improving the overall visual effect of display screen.
Additionally, the present embodiment is due to being also provided with salient point 5, and make mask body in the mask body 1 of mask through hole 3 periphery
1 thickness and the height of the height sum slightly above led lamp beads of salient point 5, can avoid the directly contact of lamp bead and plane, thus
The purpose of protection led lamp beads can be reached.Therefore, the present embodiment can enable led lamp beads to be subject on the basis of not changing mask toughness
To the protection of mask, do not make led lamp beads exposed outside, it is to avoid lamp bead is stressed directly, and with other object direct friction, reduce
The impaired probability of lamp bead, improving product stability.Thickness general control due to existing led display screen mask material of main part exists
Within 0.7mm-0.8mm, and the height of led lamp beads is typically in more than 1.0mm, and the material thickness of mask body 1 is convex with described
It is the most suitable that the height sum of point 5 arranges 0.3mm-0.5mm higher than led lamp beads.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model also can
There are various changes and modifications, these changes and improvements both fall within the range of claimed this utility model.This utility model will
Protection domain is asked to be defined by appending claims and its equivalent.
