And image.Electronic display billboard area is usually very big, will receive the erosion of dust storm sleet of nature etc., anti-dazzle cover board also has
There is strong protection intensity, can protect not damaged in outdoor electronic ink screen.
Detailed description of the invention
Specific structure of the invention is described in detail with reference to the accompanying drawing
Fig. 1 is a kind of layer structure figure of the electronic display billboard of anti-dazzle of the invention.
Wherein, the anti-dazzle cover board of 1-, 2- electronic ink screen, 3- light guide plate, the first optical adhesive layer of 4-, the second optical adhesive layer of 5-.
Specific embodiment
The most critical design of the present invention is: carrying out anti-dazzle setting on the cover sheet of electronic display billboard, make to protect
Protecting cover plate has certain mist degree, so that electronic display billboard be made to be not in strong reflective phenomenon.
For the present invention will be described in detail design feasibility, from technology contents of the invention, construction feature, realized purpose and
Effect, cooperation attached drawing are explained in detail.
Referring to Fig. 1, a kind of electronic display billboard of anti-dazzle, the ontology including electronic display billboard, described
Body includes the anti-dazzle cover board 1, light guide plate 3 and electronic ink screen 2 of 2-4mm thickness, the light guide plate 3 be located at the anti-dazzle cover board 1 with
Between the electronic ink screen 2.
As can be seen from the above description, the beneficial effects of the present invention are: the light of electronic ink screen 2 can pass through anti-dazzle cover board 1 just
Often display, it is not in concentration reflective phenomenon that sunlight, which is radiated on anti-dazzle cover board 1, which occurs diffusing reflection, will not influence personnel's reading
Writings and image on electronic ink screen.Electronic display billboard area is usually very big, will receive dust storm sleet of nature etc.
Erosion, anti-dazzle cover board 1 also have strong protection intensity, can protect be in open air electronic ink screen 2 it is not damaged.
Further, the anti-dazzle cover board 1 is made of the strengthened glass of 3mm thickness, and the anti-dazzle cover board 1 is far from the leaded light
The etching texture that the face of plate 3 carries out 8-10min through the hydrofluoric acid reagent that over-richness is 3-5% is handled.Strengthened glass has fine
Protection intensity and light transmittance make strengthened glass surface that there is certain mist degree, light is irradiated to reinforcing by etching texture processing
Diffusing reflection occurs when glass surface, and then will not influence the text and pattern on people's reading screen.In actual use test,
The strengthened glass light transmittance of etched texture is 86~90%, and glossiness is 30 °~100 °, mist degree 2-30%.Therefore it passes through
Reflective phenomenon will not occur for electronic display billboard made of the strengthened glass of over etching texture, not influence people's reading.And without
The strengthened glass of texture is etched, light transmittance is 86~90%, and glossiness is 140 °, and mist degree is less than 1%.Therefore it not etched stings
Reflective phenomenon can occur for electronic display billboard made of colored strengthened glass, influence people's reading.
Further, the anti-dazzle cover board 1 is made of strengthened glass or PMMA or PC or PMMA/PC composite plate, described anti-
Dizzy cover board 1 is provided with anti-dazzle film layer far from the face of the light guide plate 3.By the good strengthened glass of translucency or PMMA or PC or
On substrate made of PMMA/PC composite board material, selection is laid by attaching the anti-dazzle film layer with anti-dazzle function or by applying
The mode of material forms anti-dazzle film layer.In actual use test, is attached or be coated with after forming anti-dazzle film layer, anti-dazzle cover board
1 light transmittance is 86~90%, and glossiness is 30 °~100 °, mist degree 2-30%.Therefore by attached or be coated with formed it is anti-
Reflective phenomenon will not occur for electronic display billboard made of the substrate of dizzy film layer, not influence people's reading.It does not attach or is coated with
The substrate of anti-dazzle film layer is formed, light transmittance is 86~90%, and glossiness is 140 °, and mist degree is less than 1%.Therefore without attach or
Person, which is coated with electronic display billboard made of the substrate to form anti-dazzle film layer, can occur reflective phenomenon, influence people's reading.
Further, including the first optical adhesive layer 4 and the second optical adhesive layer 5, the anti-dazzle cover board 1 pass through first light
It learns glue-line 4 to be bonded with the light guide plate 3, the light guide plate 3 is pasted by second optical adhesive layer 5 with the electronic ink screen 2
It closes.Anti-dazzle cover board 1, light guide plate 3 and electronic ink screen 2 are combined by optical cement, an entirety is formed, makes electronic ink
Water screen 2 is effectively supported and is protected, meanwhile, the light that electronic ink screen 2 issues penetrates optical adhesive layer and enters light guide plate 3, then
The secondary optical adhesive layer that penetrates finally injects human eye, people is allowed to obtain the text and pattern of electronic curtain into anti-dazzle cover board 1.Optical cement
It is smaller on the direction of propagation influence of the light of electronic ink screen sending while bonding force is provided, i.e., text and pattern are shown
Show that influence is smaller.
Further, first optical adhesive layer 4 is OCA optical cement or LOCA optical cement or SCA optical cement, described second
Optical adhesive layer 5 is OCA optical cement or LOCA optical cement or SCA optical cement；The light guide plate 3 is made of glass or PMMA or PC.
OCA optical cement or LOCA optical cement or SCA optical cement have good adhesion, and it is smaller to relay direction influence to light.Glass
Or the light guide plate of PMMA or PC material, guide-lighting performance are good.
A kind of production method of the electronic display billboard of anti-dazzle, comprising steps of
(5) two layers of optical cement is attached to the upper and lower surface of light guide plate 3 respectively under conditions of pressure is 3.8-4.2Mpa；
(6) on the jig that temperature is 59.5-60.5 DEG C, by anti-dazzle cover board 1 under conditions of pressure is 4.8-5.2Mpa
It is fitted on a side of the light guide plate 3, the fitting time is 118-122s；
(7) on the jig that temperature is 59.5-60.5 DEG C, by electronic ink screen under conditions of pressure is 4.8-5.2Mpa
2 are fitted on another side of the light guide plate 3, and the fitting time is 118-122s；
(8) described in the anti-dazzle cover board 1, the light guide plate 3 and the electronic ink screen 2 that fit together being formed
The electronic display billboard of anti-dazzle, which is put into vacuum degasing machine, removes bubble present on binding face, inclined heated plate 39-
41min。
Bubble is generated between binding face will affect the extent of refraction of light, and then influence the display of text and pattern.It bonded
Journey needs to stablize output laminate pressure on idler wheel, makes adhesion process fitting uniformly, reduces bubble and generates.In vacuum degasing machine
In, achieve the purpose that eliminate bubble using the pressure difference of air bubble and vacuum environment.When the jig for being 59.5-60.5 DEG C in temperature
On, the melting of optical cement water layer, optical cement water layer hardens again after leaving jig, realizes anti-dazzle cover board 1 and light guide plate 3, light guide plate 3
With the bonding between electronic ink screen 2.
Further, the anti-dazzle cover board 1 is made of strengthened glass, before fitting, the hydrofluoric acid for the use of concentration being 3-5%
Reagent is etched texture, action time 8-10min far from the face of the light guide plate 3 to the anti-dazzle cover board 1.Use difference
The hydrofluoric acid of concentration obtains the anti-dazzle cover board 1 of different mist degrees under different action time, meets to the anti-dazzle lid of different mist degrees
The demand of plate 1.
Further, anti-dazzle film layer or anti-dazzle of spraying are sticked on the face of the anti-dazzle cover board 1 far from the light guide plate 3
Grain.The anti-dazzle film layer of anti-dazzle cover board 1 can be also made by way of attaching existing anti-dazzle film layer or the anti-dazzle particle of spraying.
