Wherein, first glue-line and the second glue-line are insulating film.
The beneficial effects of the utility model are: compared with prior art, bilayer glue sealing structure provided by the utility model
LED display is set on the first glue-line equipped with the first glue-line for covering on circuit boards and being filled in the luminous lamp bead gap LED
There is the second glue-line, the first glue-line is played, and thermal conductivity is good and moisture-proof, and the hardness of the first glue-line is less than the second glue-line
Hardness, in addition, by two layers of encapsulation, the second glue-line can play the role of anticollision；In the second glue-line far from the first glue-line
Matte surface or pattern plane are formed on surface, the light emitting source of lamp bead carries out astigmatism, forming face light by matte surface so that LED shines
Source reaches entire LED display and shines consistent effect, and light source, into after crossing the astigmatism of matte surface, light is less dazzling, compared with
To be soft, and it is set as pattern plane, so that the appearance that molding LED display is presented is more preferable, meets the demand in market.
Detailed description of the invention
Fig. 1 is the overall schematic of the utility model；
Fig. 2 is the explosive view of the utility model.
Main element symbol description is as follows:
1, the luminous lamp bead of circuit board 2, LED
3, the first glue-line 4, the second glue-line
5, matte surface 6, adhered layer.
Specific embodiment
In order to more clearly state the utility model, the utility model is further described with reference to the accompanying drawing.
Referring to Fig. 1, the utility model is to achieve the above object, the utility model provides a kind of double-deck glue sealing structure
LED display shines lamp bead 2 including circuit board 1 and attachment LED on the circuit card 1, further include covering on the circuit card 1 and
It is filled in first glue-line 3 in luminous 2 gap of lamp bead LED, and the first glue-line 3 is lower than the upper surface of the luminous lamp bead 2 of LED；First glue
3 upper surface of layer are covered with the second glue-line 4, and the hardness of the first glue-line 3 is less than the hardness of the second glue-line 4, the first glue-line 3 relative to
Second glue-line 4 is flexible glue, and the second glue-line 4 is ebonite, the second glue-line 4 is equipped in the first glue-line 3, so that after encapsulation is formed
It is good and moisture-proof that first glue-line of LED display can play thermal conductivity；Second glue-line can play the role of anticollision.
In the present embodiment, referring to Fig.2, further including adhered layer 6, one side and the circuit board 1 of adhered layer 6 are pasted with LED hair
The one side of light lamp bead 2 connects, and the another side of adhered layer 6 is connect with the first glue-line 3, since circuit board 1 is pasted with the luminous lamp bead of LED
2 one side is varnish coating, therefore relatively smooth, in this way when Nian Jie with the first glue-line 3, it is not easy to be bonded together, be easy
There is the problem of degumming, and adhesive layer 6 is set, adhered layer 6 can be alite paste, be pasted with the luminous lamp bead 2 of LED in circuit board 1
One side and the first glue-line 3 between form adhesive surface, increase the frictional force that LED shines between lamp bead 2 and the first glue-line 3, make
It is more preferable to obtain compactness.
In the present embodiment, the second glue-line 4 is matte surface 3 or pattern plane, matte surface 5 or pattern from 3 surface of the first glue-line
Face can by be covered with have transparent frosting processing release paper or graphic printing paper glass blocks and special demoulding plane bloom
It realizes, glass blocks and special demoulding plane bloom is had and be covered with processing release paper or graphic printing paper with transparent frosting
It is pressed on the upper surface of the second glue-line 4 on one side, so that release paper forms matte surface 5 or pattern plane in 4 upper surface of the second glue-line,
It carries out matt in this way or carries out the printing of pattern, after avoiding the effect of release paper matt, be difficult from the second glue
The deficiency taken off on layer 4, so that LED shines, the light emitting source of lamp bead 2 carries out astigmatism by matte surface, forms area source, reaches
Entire LED display shines consistent effect, and light source, into after crossing the astigmatism of matte surface, light is less dazzling, more soft,
Surface of second glue-line 4 far from the first glue-line 3 can also be pattern plane, so that the appearance that molding LED display is presented is more preferable,
Meet the demand in market；And second glue-line 4 thickness less than the thickness of the first glue-line 3, for example the thickness of the second glue-line 4 is less than
0.5-1 millimeters of the thickness of first glue-line 3, upper surface 0.1-1 millimeters by the height of the first glue-line 3 lower than the luminous lamp bead of LED, this
After sample LED display is assembled, the light that adjacent LED lamp bead issues not will form apparent refractive power line after reflecting, whole
Illumination effect is good.
In the present embodiment, the characteristics of according to the first glue-line 3 and the second glue-line 4, the first glue-line 3 is rubber, silica gel, asphalt mixtures modified by epoxy resin
The glue-lines such as rouge, PU glue or UV glue, and the second glue-line 4 is the wherein asphalt mixtures modified by epoxy resin for the glue-lines such as epoxy resin, PC, PVC or transparent plastic
Rouge can be to be a variety of, and meeting the first glue-line 3 can prevent from deforming, and can be with the perfect fitting of the second glue-line 4, and the second glue-line 4
Reinforced surface hardness can be carried out, realize crashworthiness and prevents the effect of deformation；And since most LED display is with circuit
The primitive color of plate and plastic face mask is background color, generally black, therefore the first glue-line 3 can be set to Transparent color, can also
With black, and the second glue-line 4 is necessary for Transparent color, and the visual impression of display is more preferable, further, the first glue-line 3 and the second glue-line
Equal 4 be insulating film, in this way according to the application places for meeting LED display.
The advantage of the utility model is:
(1) the first glue-line and the second glue-line are set, and the hardness of the first glue-line plays moisture-proof, heat dissipation less than the second glue-line
And the effect of crashworthiness；
(2) it sets matte surface on one side far from the first glue-line by the second glue-line, astigmatism, forming face is carried out by matte surface
Light source reaches entire LED display and shines consistent effect.
One or several specific embodiments of upper disclosed only the utility model, but the utility model is not limited to
This, the changes that any person skilled in the art can think of should all fall into the protection scope of the utility model.
