Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
The anti-glare optical thin film of the present invention is the globule bionics principle utilizing lotus leaf surface, as shown in Figure 2, by studying the imitation of this phenomenon, has drawn the present invention.
Minimum state can be reduced to because liquid has forever by interior, when a kind of liquid and another kind of material not affine time, surface will shrink, form small structure, as the globule figure on the lotus leaf on Fig. 3.Present invention employs above-mentioned bionics principle, by adopting two kinds of not affine resins, producing the film with anti-dazzle function, this technology can be applied to existing display outmost surface layer, and this display has antiglare effect.
As shown in Figure 4, the present invention adopts two kinds of incompatible liquid coating A and B.By methods such as existing offset printing, spraying, the printings of Ke's formula, application is formed and is positioned at FPD(FlatPanelDisplay flat-panel monitor) the first film 20 on 10 and the second film 30, wherein, the thickness H1 of the first film 20 is 2-10um, and the thickness H2 of the second film 30 is 0.05-5um.Minimum trend is retracted to because liquid itself has, coating B will shrink on the first film 20, when the thickness of coating B is when 0.05-5um, second film 30 forms some kicks of the uniform arrangement be positioned on the first film 20, thus achieve to be formed on FPD10 surface there is regularly arranged kick, and the thickness proportion of the thickness of the first film 20 and the second film 30 is greater than 2.
Anti-glare optical thin film of the present invention be a structure simple, there is the phase retardation film that concave-convex lens buys at competitive price, the visual angle of polarization type 3D liquid crystal display can be promoted.
The process that coating B forms uniform kick on the first film 20 is as follows:
Further: by the refractive index N that adjusting coating A and B is respective
a, N
b, make the refractive index N of coating A
abe greater than the refractive index N of coating B
b.According to interferometric optical principle, ambient lighting is mapped to display surface, and boundary reflection will reduce.
Further: containing fluorine or polymeric silicon by doping in coating A, can be, to this film surface, there is low surface energy, and there is self-cleaning function.
Above-mentioned coating A is fat-soluble coating, and coating B is water soluble paint, also namely: do not melt mutually between coating A and coating B.Wherein, fat-soluble coating is for becoming the coating of film substrate with fat-soluble resin, this material is using non-polar solvent (as benzene, ether, sherwood oil etc.) as dispersion medium solvent, usually with longer carbochain in the molecule of fat-soluble resin, such as: alkane, fat etc., in general, containing organism more than six carbon atom in molecule, such as: alcohol more than six carbon atom, aldehyde, ketone, acid etc. are normal not soluble in water and have fat-soluble; Water soluble paint take water as the coating of solvent composition dispersion media, all be called water soluble paint, it is a kind of environmental protection coating material, at many woodenware, car surface application is brought into use, water soluble paint film forming matter is water soluble resin, and it contains polar group usually as-OH ,-SO3H ,-NH2 ,-NHR ,-COOH etc. or not oversize carbochain.
Not affine due to two kinds of liquid coatings of the present invention, formed after the first film 20 contacts when coating B forms the second film 30 and coating A, liquid B will shrink to reduce energy in liquid.Because the very thin thickness of the second film 30 is at 0.05-5um, through curing process, the second film 30 will form thickly dotted well-regulated point projection on the first film 20 surface.
The present invention adopts existing coating, and existing technique achieves the anti-dazzle of optical thin film, and technique is simply applicable to producing in enormous quantities.
The manufacture method of the anti-glare optical thin film of the present invention, as shown in Figure 5, it is specific as follows:
The first step: as Fig. 5-C1, by spraying or printing process on backing material 10, is coated on backing material by coating A, forms the first film 20.
Described backing material 10 is the surface of FPD10, and the thickness of the first film 20 remains on 0.5-5um.
Second step: as Fig. 5-C2, heat through baking oven, allows partial solvent volatilization in the first film 20, and makes to produce certain adhesion between the first film 20 and backing material 10.
3rd step: as Fig. 5-C3 and Fig. 5-C4, coating B is sprayed on the first film 20 by spraying and forms the second film 30, the thickness controlling the second film 30, between 0.05-2um, makes the second film 30 be formed and is positioned at the thickly dotted well-regulated point projection of the first film 20 surface formation.
Because the thick end of the second film 30 is thinner, the second ultra-thin thin layer need be realized by high pressure painting, after the solidification of rear end, the kick formed on the first film 20 to be of a size of as 1um at the end, highly be the conicle of 0.2um.
4th step: as Fig. 5-C5, again hyperthermia drying, forms anti-glare optical thin film of the present invention.
Anti-glare optical thin film of the present invention and manufacture method thereof is introduced by above-mentioned.
