Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.

Refer to Fig. 1, shown a kind of coiled strip 100, is curled into by nesa coating 10.Refer to Fig. 2 and Fig. 3, be depicted as the section layer structure of nesa coating 10, diaphragm 12 is endured in the heat-resisting increasing that nesa coating 10 comprises ITO conducting film 11 and is connected to ITO conducting film 11 lower surface.ITO conducting film 11 comprises from top to bottom ITO conductive layer 111, optical adjustment layer 112, substrate layer 113 and the hard conating 114 that layer is successively established.

ITO conductive layer 111 is indium tin oxide conductive layer, its tin oxide (SnO2) ratio is between 1 ~ 10%, and be formed in described optical adjustment layer 112 in the mode of thin film deposition, and via at 150 DEG C through 60 minutes burin-in process, the sheet resistance of ITO conductive layer 111 is through 1N salt acid soak after 3 minutes, its Bianization Shuai≤20%, described ITO layer 3 thickness is 20nm ~ 30nm, the sheet resistance You Xuan Wei≤400 Ω/ of ITO layer 3, Ω/ is the unit of film resistor, i.e. ohm-sq.

Optical adjustment layer 112 is formed on the upper surface of substrate layer 113, and for adjusting the refractive index of incident light, optical adjustment layer 112 can be one or more layers of textural association and forms.When being a low-index layer, refractive index is preferably 1.35-1.5, and thickness is preferably 5-70nm.Optical adjustment layer 112 can select following material one or more obtain: the oxide of magnesium fluoride, silicon, the nitrogen oxide of silicon, acryl resin etc., preferred silicon dioxide but be not limited to above material.When optical adjustment layer 112 is the structure of more than one deck, use the overlapping collocation of high low-index layer to form, the refractive index of high refractive index layer is preferably 1.6-2.3, and the refractive index of low-index layer is preferably 1.35-1.5.

Substrate layer 113 is light-permeable material, and surface uniform and smooth, its material can be the one in such as PET, PEN, PC, COP or COC, is preferably PET film.

Hard conating 114 is for having the slip hard conating of anti scuffing effect or the anti-hyun smooth hard conating containing outstanding particle, and its thickness is 0.5 ~ 5 μm.

The adhesion layer 122 that diaphragm 12 comprises diaphragm substrate layer 121 and is arranged on diaphragm substrate layer 121 upper surface is endured in heat-resisting increasing, the lower surface of the hard conating of adhesion layer upper surface bonding ITO conducting film.Diaphragm substrate layer 121 is identical with described substrate layer 113 material, preferably selects PET film.

Refer to Fig. 4, very property test is carried out to nesa coating, get the electrically conducting transparent film sheet 10 that a L*W (long * is wide) is 20*5cm, be placed in marble or glass platform 20, sheet material 10 is required to be smooth nothing and sticks up the state of getting, be placed in marble platform edge, the unsettled 10cm in one end of the length of sheet material 10,10cm remaining on platform pushes down sheet material 10 by loading 21, then the unsettled end of sheet material and horizontal angle is measured, angle is less, the sheet material property endured better (minimum is 0 degree, is 90 degree to the maximum).And the ITO conducting film 11 of same mode to electrically conducting transparent film sheet 10 carries out very property test.The relevant parameter recorded and conclusion as follows.(in process operations, zero is easy to operate, and △ still can operate, ╳ (easy injured) not easy to operate).

ITO conducting film 11 property endured test data refers to following table one;

Table one,

Ito film base material thickness	Base material pliability	Very property	Process operations
				23umm	Φ＝3mm3	85 degree	╳
50um	Φ＝4mm	60 degree	╳
				100um	Φ＝6mm	30 degree	╳
125um	Φ＝8mm	20 degree	△
				188um	Φ＝10mm	8 degree	○
250um	Φ＝12mm	6 degree	○

Nesa coating 10 property endured test data refers to following table two;

Table two,

Can find out from table one, because of slimming demand, ito film base material thickness does thinner and thinner, but causes process operations not easily because very property is not good, reduces yield.From ITO conducting film base material thickness when below 125um, very property about 20 degree, between exercisable critical edges; When thickness arrives 188um, the additionally increasing that substantially do not need to arrange in pairs or groups is endured diaphragm and can be met process requirement.So, nesa coating 10 is when enduring diaphragm 12 without heat-resisting increasing, and ITO conducting film base material thickness is selected at more than 125um, considers, be preferably selected in below 188um for thickness.In conjunction with consulting table 2; nesa coating 10 has heat-resisting increasing when enduring diaphragm 12, and require that lower inclined angle need be less than 30 degree according to very property, very property is more preferred from less than 20 degree; ito film substrate layer thickness and diaphragm substrate layer thickness sum are selected between 145um to 250um, can guarantee process requirement.Further, increasing very heat-resisting protective film base material is good with PET protection film.

Refer to Fig. 5, pliability test is carried out to nesa coating, get the electrically conducting transparent film sheet 10 of a 20*5cm (long * is wide), be placed on a carrying platform 30, and select the roller 31 of different coil diameter, sheet material 10 prolongs this roller 31 flexing 180 degree, after replication former state again, whether tortoise is bad for the face of observation sheet material 10, and measures resistance variations before and after conducting film, represents that this coiled strip is defective more than 10%.After tested, within this nesa coating pliability need reach coil diameter (being namely rolled into the diameter in cylinder after reel) 12mm, pliability is more preferred from below coil diameter 10mm.After diaphragm is endured in this nesa coating attaching increasing, through temperature 130 degree, 30 minutes time tested, and its warpage degree is less than 20mm, meets pliability test request.

In sum, the utility model nesa coating, by enduring diaphragm at ITO conducting film in conjunction with heat-resisting increasing, makes ITO conducting film also have required very property in the pliability having itself concurrently simultaneously, and guarantees the yield of overall process, avoid injured.

As long as without prejudice to the thought that the utility model is created, carry out combination in any to various different embodiment of the present utility model, all should be considered as content disclosed in the utility model; Within the scope of technical conceive of the present utility model, to the combination in any of the thought created without prejudice to the utility model that technical scheme carries out that multiple simple modification and different embodiment carry out, all should within protection range of the present utility model.
