Technical field

The present invention relates to display with surfacing with have this display display with surfacing, this display is arranged on glass housing, plastic casing etc. with surfacing and shows surface with displays such as image display such as display and personal computer, televisor, portable phones.

Background technology

In this display, if from the light of outside in this surface (display surface) no scattering ground reflection, then as being mapped to herein, be difficult to see the image of inside, so be provided with the antiglare film that is used to make from the light generation scattering of outside at display surface.

But, when using display, because finger touches this surface, so can adhere to from the teeth outwards by (hereinafter referred are " fingerprint ") such as the fingerprints that lipid components produced from biosome such as sebum, the visibility (Knowledge Recognize of image) and impaired easily.For this reason, proposed to be used to prevent the countermeasure of fingerprint attached to display surface.For example, following antiglare film is disclosed: lamination resin bed on the transparent base film, form antiglare layer thereon with soil resistance, constitute antiglare film (for example, with reference to patent documentation 1) thus.Antiglare layer with soil resistance contains the fluorine modified compound, spends greater than 43 with the contact angle of glyceryl triacetate.

Patent documentation 1: TOHKEMY 2000-194272 communique (second page and the 4th page)

The above-mentioned stain-proofing layer that is formed by fluorochemicals has following advantage: because its surface free energy is low, thus the minimizing of the adhesion amount of fingerprint, and accompanying fingerprint is wiped easily.But, antiglare layer contains fluorochemicals, and spend greater than 43 with the contact angle of glyceryl triacetate, so, the lipid components from biosome that is used to form attached to the fingerprint on the antiglare layer forms fine droplet easily, this fine droplet is to adhere to the descried major reason of fingerprint, and light at this fine droplet place diffuse reflection takes place, and fingerprint does not still improve in the obviously visible this point of display surface.Therefore, the problem that has the display image visibility decline of display.

Summary of the invention

The object of the present invention is to provide a kind of display with surfacing with have this display display with surfacing, this display has anti-dazzle function and makes the fingerprint attached to the surface be difficult for tangible function with surfacing, can improve visibility.

For the fingerprint attached to display surface, owing to form fine droplet from the lipid components of biosome on this surface, light is by this fine droplet generation diffuse reflection, thereby fingerprint is seen by eyes.Therefore, change the thinking of angle: if even producing to adhere to from the lipid components of biosome does not generate this fine droplet yet, for example, display surface is in wetting regime, then can make visual in fingerprint obvious hardly.That is to say, if to be used to show the concave-convex surface portion of anti-dazzle property, minimizing is from the adhesion amount of the lipid components of biosome, and make and constitute this material and merge easily with lipid components from biosome with concavo-convex surface, absorb lipid components more by siphonage (kapillary now looks like) from biosome, then can prevent accompanying fingerprint obvious effects effectively, finish the present invention thus.

The display surfacing of first aspect present invention is to be configured in the surface of display and the display surfacing that uses, it is characterized in that, it constitutes by antiglare layer is set on transparent base, this antiglare layer has jog on the surface that is formed by resin, and the planar film that is formed by above-mentioned resin and the contact angle of oleic acid drop are below 60 degree.

According to the present invention, can access following effect.

With in the surfacing, by being formed by resin and the surface has the antiglare layer of jog, the reflection of light direction is changed and scattering at display of the present invention, inhibition enters into the reflected light of eyes, shows anti-dazzle property.Further infer, owing to have jog, can guide surperficial recess (a kind of kapillary) into based on the lipid components that siphonage will form fingerprint from biosome on the surface.Infer in addition, since the planar film that forms by above-mentioned resin and the contact angle of oleic acid drop be set at 60 spend below, thereby the resin that constitutes antiglare layer lipid components easy and from biosome merges, lipid components from biosome is drawn towards surperficial recess rapidly, and accompanying fingerprint is difficult to be recognized.Therefore, display has anti-dazzle function and make the fingerprint attached to the surface be difficult for tangible function in the lump with surfacing, can improve the visibility of display image etc.

Fig. 2 (a) is the sectional view of other example of schematically illustrated display usefulness surfacing 10 of the present invention to Fig. 2 (c).Shown in Fig. 2 (a), this display is with in the surfacing 10, and the buckle layer 14 among above-mentioned Fig. 1 is provided with has confluent coating (fingerprint fused layer) 16 to the lipid components from biosome, and other structure is identical with Fig. 1.Shown in Fig. 2 (b), this display forms buckle layer 14 with surfacing 10 by concavo-convex transfer printing, and the resin that constitutes this buckle layer 14 has amalgamation to the lipid components from biosome, and other structure is identical with Fig. 1.Shown in Fig. 2 (c), this display forms buckle layer 14 with surfacing 10 by concavo-convex transfer printing, and this buckle layer 14 is provided with coating 16, and 16 pairs of lipid components from biosome of this coating have amalgamation, and other structure is identical with Fig. 1.Shown in Fig. 2 (a) and Fig. 2 (c), buckle layer 14 is provided with under the situation of coating 16, constitutes antiglare layer by these buckle layers 14 and coating 16.

As above-mentioned transparent base 11, can use transparent resin sheet, transparent resin film, transparency glass plate etc., be not particularly limited.As the resin material that forms transparent base 11, specifically, can enumerate poly-(methyl) acrylic resin, poly-(methyl) vinyl cyanide resin, polystyrene resins, the polysulfones resin, the polyether sulfone resin, the polyethers resin, the polymethylpentene resinoid, Triafol T (TAC) resinoid, polyethylene terephthalate (PET) resinoid, the polyurethanes resin, the regenerated cellulose resinoid, the diacetyl cellulose resinoid, the cellulose acetate-butyrate resinoid, polyester resin, acrylonitrile-styrene-butadiene tri-component copolymerization resinoid, polycarbonate resin, the polyetherketone resinoid, polyvinyl chloride resin, the Vingon resinoid, polyvinyl alcohol resin, nylon-based resin, polythylene resin, polypropylene-based resin, polyamide-based resin, polyimide based resin, norbornene resin etc.Wherein, from viewpoints such as versatility and purposes actual effects, preferred poly-(methyl) acrylic resin, polystyrene resins, Triafol T (TAC) resinoid, polyethylene terephthalate (PET) resinoid, polycarbonate resin.

The thickness of transparent base 11 is generally 10 μ m～5000 μ m, is preferably 25 μ m～1000 μ m, more preferably 35 μ m～500 μ m.This thickness is under the situation of 10 μ m～5000 μ m, and operability is good, and the intensity of transparent base 11 does not descend, necessarily thickening.

As mentioned above, buckle layer 14 utilizes resin to be formed with jog 13, need be preferably below 50 degree below 60 degree by the contact angle of formed planar film of above-mentioned resin and oleic acid drop, more preferably 1 degree～40 degree.This buckle layer 14 can be to have jog 13 on the surface of himself as mentioned above, and has good confluent mode with lipid components from biosome, also can be to have a jog 13 on the surface, be provided with thereon and have the mode of good confluent coating 16 from the lipid components of biosome.By inference, by making this contact angle below 60 degree, the resin lipid components easy and from biosome that constitutes buckle layer 14 merges, guided into the recess 13a on buckle layer 14 or coating 16 surfaces rapidly from the lipid components of biosome, thereby can be realized that the fingerprint that adheres to is difficult to descried function.Under the situations of contact angle greater than 60 degree, form fine droplet easily from the lipid components of biosome, make the light diffuse reflection, the visibility variation of display image etc. is so be not suitable for.

For example, for contact type panel, have to be assembled in above-mentioned various display and to become one-piece type situation and be disposed on the display surface of various displays and become the situation of divergence type.As the mode of contact type panel, can use the mode of any known, do not limit especially.Specifically, can enumerate modes such as ultrasound wave mode, resistive film mode, static capacity mode, electric mode of texturing, magnetism mode of texturing, infrared mode and way of electromagnetic induction.Consider from the aspect of power consumption and manufacturing cost, be preferably the contact type panel of resistive film mode, consider, be preferably the contact type panel of way of electromagnetic induction from the resolving power aspect.

Fig. 3 (a) is the sectional view of the contact type panel 20 of expression resistive film mode.As shown in the drawing, its structure is as follows: the base material of fixation side (downside among the figure) and movable side (upside among the figure) 23,24 is formed by the transparent resin sheet, this base material 23,24 is provided with transparent conductive film 21,22 at single face respectively, dispose this base material 23,24 and make transparent conducting film 21,22 opposite to one another, make described base material 23,24 keep certain intervals to constitute with reinforcing material 25 adhesion on every side with adhesion.Point-like is provided with a plurality of insulating spacers 26 on the one side of transparent electrical conductance film 21, becomes insulation system thereby make between the transparent conducting film opposite to one another 21,22.Wait the main body that constitutes contact type panel by above-mentioned base material 23,24, transparent conducting film 21,22, insulating spacer 26.The base material 24 of movable side is provided with the aforementioned display device surfacing.Or the contact type panel 20 of following formation shown in Fig. 3 (b): on base material 24 surfaces of movable side,, the display that is formed with buckle layer 14 is set with surfacing 10 on its surface by adhering agent layer 15 transparent base 11 of adhering.And, by pushing display with surfacing 10, the transparent conducting film 22 of movable side is contacted with the transparent conducting film 21 of fixation side, thereby conduct and can import with finger 27.

The contact type panel 20 of way of electromagnetic induction constitutes by the sectional view of Fig. 4.That is, be bonded with display with surfacing 10 in the surperficial lamination of the base material 24 that constitutes by transparent resin, and, being provided with a position detector 28 at the back side of base material 24, this position detector 28 is covered with receiving circuit on liquid crystal cell (LCD).Display constitutes with surfacing 10: the surface at the transparent base 11 that is made of the transparent resin sheet is provided with buckle layer 14, is provided with adhering agent layer 15 overleaf.Further, possesses the electromagnetic type input pen 29 that is built-in with not shown transmission coil.And, by pushing display with input pen 29, produce electromagnetic induction with surfacing 10, utilize a position detector 28 to detect the electromagnetic wave that is produced, the record input position.

If the effect of present embodiment is described, then display with surfacing 10 be by transparent base 11 and on buckle layer 14 constituted, this buckle layer 14 has jog 13 on the surface that is formed by resin.This this display is configured under the situation about using as the surface of the contact type panel 20 of the resistive film mode of display with surfacing 10,, carries out the operation of contact type panel 20 by pushing the surfaces of display with surfacing 10 to point 27.At this moment, at the lipid components from biosome of display with the surface attachment formation fingerprint of surfacing 10, the image visibility of contact type panel 20 descends.Contact type panel 20 is under the situation of way of electromagnetic induction, operate with input pen 29, and the mode of operation that does not adopt finger 27 to contact, but when operation input pen 29, palm touches display surface, can make from the lipid components of biosome attached to it, even or operate sometimes, finger tip touches on the display surface, and makes from the lipid components of biosome attached to it.Under this situation, similarly the image visibility of contact type panel 20 descends.

But, because buckle layer 14 has jog 13 on the surface that is formed by resin, so the reflection of light direction that incides the surface changes and scattering at jog 13, has suppressed to enter into the reflected light of eyes, reduces dazzling degree.And by the siphonage that the jog 13 on surface is shown, the lipid components from biosome that forms fingerprint is drawn towards the recess 13a on surface.And, constituting the formed planar film of resin of buckle layer 14 and the contact angle of oleic acid drop is set to below 60 degree, so, this resin lipid components easy and from biosome merges, guided into the recess 13a on surface rapidly from the lipid components of biosome, fingerprint becomes can not be in sight, can improve the image visibility of contact type panel 20.

According to preferred implementation, can access following effect.

With in the surfacing 10, because buckle layer 14 has jog 13 on the surface that is formed by resin, and the light generation scattering of feasible reflection demonstrates anti-dazzle property at display.And by have jog 13 on the surface, according to siphonage, the lipid components from biosome that forms fingerprint is drawn towards the recess 13a on surface.In addition, constituting the formed planar film of resin on surface and the contact angle of oleic acid drop is set to below 60 degree, thereby the resin that constitutes buckle layer 14 lipid components easy and from biosome merges, from the recess 13a that the lipid components of biosome is guided into the surface rapidly, accompanying fingerprint becomes and is difficult to identification.Therefore, display is with the function that surfacing 10 has anti-dazzle function in the lump and makes the fingerprint attached to the surface become and be difficult to recognize, can improve the visibility of the image etc. of display.

In addition by inference, owing to contain the metal oxide that mean grain size is 1nm～200nm in the resin, thereby make the jog 13 on antiglare layer surface become the fine part of nanoscale, promote siphonage, from the recess that the lipid components of biosome is guided into the antiglare layer surface rapidly, accompanying fingerprint becomes and is difficult to see.

By make in the above-mentioned resin contain fluorine atoms not or contain make this fluorine atom under the situation of fluorine atom content below 0.05 quality %, the fine dropletization from the lipid components of biosome due to the fluorine atom is inhibited, and can suppresses the diffuse reflection of light.

Jog 13 for above-mentioned buckle layer 14 surfaces, the arithmetic average roughness (Ra) of JIS B 0601-1994 defined is 0.05 μ m～5 μ m, the equispaced of jog 13 (Sm) is 5 μ m～500 μ m, thereby can more effectively demonstrate the siphonage based on jog 13.In the surface state of such jog 13, haze value is less, in tangible zone, therefore, can play preventing the fingerprint obvious effects effectively attached to the fingerprint on surface.

This display is configured in the surface of display with surfacing 10, constitutes display, thereby makes display play above-mentioned effect with surfacing 10, can give full play to the function of display.
