Embodiment
Below, the preferred embodiments of the present invention are described in detail with reference to accompanying drawing.
Embodiment one
First, the necessary etching solution when impregnate glass substrate is prepared.
Etching solution 600 is fabricated to and comprises fluorine (F) ion, and mix the weak acid of distilled water and/or citric acid (being not limited thereto) etc., spray in the mode using sprayer etc. to apply external pressure to glass substrate, the etching performance thus under this occupation mode of constant and manufacture etching solution.Now, select the content ratio of the etch capabilities that can possess within several μm per minute better in boosting productivity to manufacture etching solution.
Now, thickness for the glass substrate used does not limit, employ the glass substrate of 0.2mm to 2mm in the present embodiment, etching solution is made up of the acid solution comprising F ion, but without the need to its content ratio is limited to some number ranges, as long as enable by adjustment rose and its expulsion pressure to glass substrate spray and the etching test result that draws with the rate etch glass substrate within etching number per minute μm, then can become satisfied etching solution.This etch capabilities is also exemplary, is the etching solution considered productivity ratio etc. and have selected the etch capabilities had as above.
Material for glass substrate does not also limit, and employs the soda lime glass substrate between 0.2mm to 2mm in the present embodiment, and sets rank to the concentration of F ion, simultaneously through having fixing expulsion pressure (0.5 to 2kgf/cm 2) sprayer injection etching test, constitute etching solution with various mixing ratio.The manufacture of this etching solution is exemplary, and the manufacture of etching solution, by mutually adjusting the concentration of F ion, expulsion pressure and time of immersion technique described later together with etch capabilities related to this, can have the embodiment of multiple combination completely.
When the etching solution equally manufactured as mentioned above is at room temperature filled in tank, and impregnate glass substrate and make glass substrate in the several seconds to when maintaining immersion state in several minutes, the nanometer of severals nm as shown in the photo of Fig. 4 extremely several μm of sizes will be produced on the glass substrate to the indenture of micron.Compared to the left photo of Fig. 4, right photograph is high magnification photo.This can with the immersion process implementing of Fig. 3 before the surface of general glass substrate compare, nanometer is formed as illustrated in fig. 4 randomly to the size of micron indenture.This nanometer to micron indenture as concavees lens, irregular reference is caused while divergent rays, prevent from producing total reflection etc. on the critical surface of plane, thus make more light transmission outer (namely to glass substrate, more light propagates into outside glass substrate, to present higher brightness).For the etching solution with predetermined etch capabilities, if the immersion time is too short, then the formation degree of indenture does not reach requirement, the extraction efficiency of light also can not rise, but the immersion of exceedance minute is then unfavorable for productivity ratio, and also may there is the albinism that glass substrate fogs, be therefore necessary to select the best immersion time.The immersion time can be adjusted to best selection according to the etch capabilities of etching solution and the thickness etc. of glass substrate as described above.
Nanometer can be formed at the two sides of glass substrate to micron indenture, but mask or film etc. also can be utilized only to be formed on a side.

Then, utilize mild acid wash glass substrate, to prevent the strong basicity component residue of sodium hydrate aqueous solution in glass substrate.The weak acid used comprises citric acid, acetic acid, carbonic acid etc., and its pH value can be prepared as 3 or 4 and use.The clean temperature of weak acid is utilized to be set as normal temperature to 60 DEG C, be preferably 45 ± 5 DEG C, the glass substrate that will clean is loaded into conveyer belt by cleaning way employing and level is transferred, and by nozzle, weak acid solution is ejected into the upper and lower sides of glass substrate with spray pattern, the mode of cleaning on the whole thus.The expulsion pressure of nozzle is decided to be 1.0 ± 0.5kgf/cm 2, the screen of glass substrate is decided to be 1.0 to 1.5m/min, with applicable cleaning, is preferably set to 1.2m/min.This cleaning condition is only exemplary, can mutually adjust variable and use other selection also can reach optimization.
After having carried out described mild acid wash step, clean glass substrate with distilled water (pure water), terminated cleaning step thus.
Utilized light source to carry out according to the luminance test of light extraction efficiency by above-mentioned technique to being formed with the glass substrate of nanometer to micron indenture, its photo as shown in Figures 5 and 6.From Fig. 5 and Fig. 6, can with the naked eye confirm to present according to the difference of immersion time under identical etching solution, according to being formed with the luminance difference of nanometer to the light extraction efficiency of the glass substrate of micron indenture.Thereby, it is possible to find out composition and the combination of immersion time of the etching solution presenting best brightness.
Constructed in accordance go out nanometer to the light extraction efficiency of the glass substrate of micron indenture that is formed compare existing light extraction efficiency and improve 25% to 50%, its result presents more than 25% to 30% light extraction efficiency for luminous quantity.
Embodiment two
Below, with reference to Fig. 7 to Figure 11, another embodiment of the present invention is described.
As shown in Figure 7, prepare laterally and to be vertically all formed with that there are the several μm of mesh masks 100 to more than 300 mesh of tens of μm of sizes, and be positioned on glass substrate 200, as shown in Figure 8, comprise the slurry of metal dust with silk screen printing coating.The metal dust being contained in described slurry is made up of several μm of metallics to tens of μm of sizes, and the kind for metal is not particularly limited, as long as can by fluorine ion (F +) etching is just passable, but preferably use one of them in Ag, Fe, Cu, Al.Described slurry uses mixed metal powder and adhesive (binder) and manufactures the slurry of the state of easily coating.
As shown in Figure 8, by utilizing squash type scraper by described slurry silk screen printing on glass substrate 200, metallic 300 is pressed on glass substrate 200 as illustrated in fig. 9 by the mesh of described mesh mask 100.In this case, be fixing metal particle 300, in the drying machine of 50 DEG C to 200 DEG C, drying implemented to the glass substrate 200 being coated with slurry.The drying that drying can adopt natural drying or use ultraviolet (UV) to irradiate, has no particular limits for drying time, suitably can adjust according to the state of slurry.
After drying terminates, remove described mesh mask 100 from glass substrate 200, and to described glass substrate 200 sprayer sprayed resin material, fill the blank between metallic 300 by resin material as illustrated in fig. 10 thus.Now used resin material should use and can not to be pasted onto on slurry and can not by the heat-curing resin of fluoride ion etch, is preferably that to use in epoxy resin or mylar some.
In order to make described heat-curing resin form resin portion 400 securely between metallic 300, at 50 DEG C to 200 DEG C, carry out drying.Glass substrate 200 be coated with metallic 300 that average grain diameter is micron order (several μm to tens of μm) and utilize resin portion 400 to fill between metallic 300, and this glass substrate 200 is put into etching solution once etching.The object once etched is to melt described metallic 300, and then etches the glass substrate 200 of the part that metallic 300 covers, to form the micron indenture 500 of micron-scale.Therefore, fluorine ion (F is preferably used +) etching solution 600 that concentration is slightly high, preferably at least comprise the F of 55% +etching solution 600.But, without the need to F +concentration limits especially, this is because can implement the etching of short time in higher concentrations, or implements etching for a long time at low concentrations.
Take out glass substrate 200 after completing once etching, and by being immersed in alkaline solution, resin portion 400 is stripped out or is peeled off by physics mode, and then put into new etching solution and implement second etch.The object of second etch is that in the micron indenture 500 formed, form average diameter is the nanometer indenture 550 of several nm to hundreds of nm nano-scale, and should implement relatively once to etch more weak etching.
That is, compare and once etch, reduce the concentration of etching solution, if or the etching solution of same concentrations, then reduce etching period, or suitably reduce concentration and the etching period of etching solution, form nanometer indenture 550 (with reference to Figure 11).
When completing second etch, from etching solution, take out glass substrate 200, clean with the cleaning way described in previous embodiment one.
Embodiment three
Another embodiment of the present invention is described in detail referring to Figure 12 to Figure 15.
The size prep solution groove of corresponding glass substrate, and load in this solution tank and improve fluorine ion (F a little +) etching solution 600 of concentration.Be preferably the F using and comprise at least 55% +etching solution 600, but without the need to being particularly limited to F +concentration, this is because the etching can implementing the short time in higher concentrations, or implements etching for a long time at low concentrations.When loading etching solution 600 in solution tank, in the height of solution tank should vacant go out several about cm, be preferably vacant go out 5cm to 10cm, with the etching steam space that can exist produced after guaranteeing solution evaporation.The direct placing glass substrate in the upper end of described solution tank, implements etching to make the etching steam (fume) comprising fluorine ion to the surface of described glass substrate.Accordingly, multiple indenture with the average diameter of nano-scale will be formed randomly on the surface of glass substrate.
That is, the molecule of composition etching steam does the Brownian movement of random movement in the clearance spaces of described solution tank, the therefore surface of Ground shock waves glass substrate out of order, thus with fine size etching glass substrate surface, forms the indenture of nano-scale thus randomly.
Consider productivity ratio, when the concentration of etching solution 600 being decided to be high concentration (about 70%), it is then relatively abundant that etching period reaches 1 minute to 5 minutes, along with the concentration of etching solution is high, and can the slightly high alkaline cleaning fluid of working concentration in cleaning.
And, as one of scheme boosted productivity, also can select the etching solution that volatility is high, to form nanometer indenture at short notice.
In the present embodiment, under normal temperature (18 ~ 25 DEG C), make F +concentration is the etching solution evaporation of about 55%, jetted 15 seconds to the 1 point etching steam of about 30 seconds thus to glass substrate.
Below, with reference to Figure 13, another embodiment of the present invention is described.
