Protect glass 7) inside, transparent LCD 9 and transparent LCD 9 be set in structural member 6, and is installed on the vehicles by structural member 6
Or on building.
Since transparent LCD 9 can not shine in itself, it is therefore desirable to which LED5 and light guide plate provide light source, light guide plate for it
Selection such as an above-mentioned embodiment shown in unidirectionally go out light guide tabula rasa 1, and be positioned in transparent LCD 9 with protect glass 7 it
Between, LED5 is set to the side of unidirectional light guide tabula rasa 1 out.Meanwhile also needing to be arranged a pdlc film 8 in the back side of transparent LCD 9,
The light source of transparent LCD 9 is adjusted.
Transparent LCD 9 on daytime in use, can work by natural light, close LED5, can watch by opening pdlc film 8
The content that transparent LCD 9 plays, can also be with the scenery of viewing window open air；When at night in use, closing pdlc film 8, is opened
LED5, the light guide tabula rasa 1 that unidirectionally goes out through this embodiment is that transparent LCD 9 provides uniform source of light, and transparent LCD 9 is supported to continue work
Make, while outside does not have a light pollution.
In three embodiments of the invention, referring to FIG. 4, unidirectionally going out light guide tabula rasa 1 it illustrates three embodiments of the invention
Production method 4 structural schematic diagram.The production method 4 of unidirectional light guide tabula rasa 1 out includes the following steps 401-403, in which:
Step 401, carrier is provided.One light conducting plate body 2 is provided.
Specifically, being preferably glass, organic glass (Polymethyl for the selection of the material of light conducting plate body 2
Methacrylate, PMMA) or polycarbonate (Polycarbonate, PC), but be not limited thereto.
More specifically, being selected as 1-10 millimeters (mm) for the thickness of light conducting plate body 2, for example, can for 1mm, 3mm,
5mm, 7mm or 10mm, but be not limited thereto.
Step 402, ink is formed.Aluminium powder, titanium dioxide and synthetic resin are mixed, ink is formed.
Specifically, the weight content of titanium dioxide is 33%, the weight content of aluminium powder is more than or equal to 27%, remaining is adhesive
Weight content, but be not limited thereto.
Specifically, the weight ratio of aluminium powder, titanium dioxide and synthetic resin is 27:33:40, but it is not limited thereto.
Specifically, titanium dioxide (TiO in ink2) specific gravity 4.26g/cm3, the specific gravity of aluminium (Al) is 2.7g/cm3, due to
Titanium dioxide (TiO2) specific gravity be greater than aluminium (Al) specific gravity, two kinds of material mixings together when, titanium dioxide (TiO2) can under
Heavy, aluminium (Al) can float, and form layering shape, synthetic resin is adhesive, together by two kinds of binding substances.
Step 403, multiple sites are formed.Using ink as raw material, multiple sites 3 are formed in the side of light conducting plate body 2.
Specifically, ink to be applied to the outside of light conducting plate body 2, due to ink using printing or inkjet printing mode
It is titanium dioxide (TiO2) lower layer, aluminium (Al) upper layer formation be layered shape so that formed multiple sites 3 also in point
Stratiform namely the first ink layer 31 and the second ink layer 32, the first ink layer 31 are located in light conducting plate body 2, titanium dioxide
(TiO2) it is located at the first ink layer 31, the second ink layer 32 is located on the first ink layer 31, and aluminium (Al) is located at the second ink layer 32
On.
Specifically, each site 3 with a thickness of being more than or equal to 30 microns, each site 3 (first in the thickness range
Ink layer 31) both can effective reflection light, (the second ink layer 32) can effectively prevent to be penetrated by light again, but not with this
It is limited.
Unidirectionally go out the production method 4 of light guide tabula rasa 1 and the design method of traditional light guide plate mesh point disclosed in the present embodiment
It compares, is the change being in the change and product using effect of the formula of ink, does not need special installation or technique, at
This is cheap, the requirement of uniform area light source not only may be implemented by the unidirectional light guide tabula rasa 1 out of the present embodiment production, but also multiple
Visual influence also very slight (the application is silvery white in color), is especially watched in site 3 in larger distance.
In four embodiments of the invention, the production method 4 of light guide tabula rasa 1 is unidirectionally gone out according to shown in above-mentioned three embodiment
Production unidirectionally goes out light guide tabula rasa 1, wherein aluminium powder: titanium dioxide: the ratio of synthetic resin is 27:33:40, ink thickness 35
Micron.
For common TV, general brightness requirement is in 300nit or so, since transparent LCD penetrance is 40% or so, such as
Fruit will reach requirement, and the brightness of backlight needs 800nit or more namely light guide plate to need to provide the brightness of 800nit.
When using the light guide plate of the prior art, go out light ratio substantially in 1:1 due to its front and back sides, existing skill
For the light guide plate of art while front provides the brightness of 800nit, the brightness at the back side is also 800nit, is had greater environmental impacts,
It will cause light pollution.
When using unidirectionally light guide tabula rasa 1 out manufactured in the present embodiment, while front provides the brightness of 800nit,
Back side brightness is reduced to 20nit, and therefore, the ratio for going out light of the unidirectional front and back sides of light guide tabula rasa 1 out of the present embodiment can reach 40:
1, compared with the light guide plate of the prior art, the light emission rate of guide-lighting back can be effectively reduced, and then reduce light to the bad of environment
It influences.
Several preferred embodiments of the invention have shown and described in above description, but as previously described, it should be understood that this hair
It is bright to be not limited to forms disclosed herein, it is not to be taken as the exclusion to other embodiments, and can be used for various other
Combination, modification and environment, and can within that scope of the inventive concept describe herein, by the technology of above-mentioned introduction or related fields or
Knowledge is modified.And changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, then it all should be
