Abstract
The utility model provides a transparent electric conduction film, includes a PET substrate layer, attaches to the ITO transparent conducting film of a PET substrate layer lower surface, supreme adhering to in proper order has first layer, the 2nd PET substrate layer and anti -dazzling layer after that at the upper surface of a PET substrate layer under by, and wherein, the refracting index of a PET substrate layer is greater than the refracting index of the 2nd PET substrate layer. The utility model discloses a transparent electric conduction film sets up two -layer PET substrate layer, and two PET substrate layers are through catching the stacking together, and just the refracting index of two PET substrate layers is different to, satisfying under the prerequisite of strength requirement, ensured that transparent electric conduction film has higher luminousness.
Description
Technical field
The utility model relates to a kind of nesa coating.
Background technology
Nesa coating is a kind of can to conduct electricity and can the film material of printing opacity, and it is mainly applied on the display screen of electronic equipment, and comparatively common nesa coating is ito film; Along with the development of electronic product correlation technique, the requirement for nesa coating is more and more higher.
Existing nesa coating normally comprises pet layer and is deposited on the ITO transparency conducting layer on pet layer, this film material has higher transmissivity, that is, by this film material as after on the screen of electronic equipment, screen can be made to have higher definition and color rendition degree.But the electronic equipment of present stage, it adopts touch-screen mostly, and this proposes higher requirement to the intensity of screen, and the structure of existing nesa coating is difficult to meet requirement of strength.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model aims to provide the higher nesa coating of a kind of intensity.
For achieving the above object, the utility model adopts following technical scheme:
A kind of nesa coating, comprise the first PET base material layer, be attached to the ITO transparency conducting layer of the first PET base material layer lower surface, the first following layer, the second PET base material layer and anti-dazzle photosphere is attached with from the bottom to top successively at the upper surface of the first PET base material layer, wherein, the refractive index of the first PET base material layer is greater than the refractive index of the second PET base material layer.
Between anti-dazzle photosphere and the second PET base material layer, be also provided with a reinforced layer, between reinforced layer and the second PET base material layer, be provided with second following layer will be engaged togather both it.
The thickness of ITO transparency conducting layer is 25 ~ 35nm.
The thickness of the first PET base material layer is 45-60nm, and the thickness of the second PET base material layer is 80-90nm.
The beneficial effects of the utility model are:
Compared to prior art, nesa coating of the present utility model arranges two-layer PET base material layer, and two PET base material layer are combined by following layer, and the refractive index of two PET base material layer is different, thus, under the prerequisite meeting requirement of strength, ensure that nesa coating has higher light transmittance.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of nesa coating of the utility model.
Fig. 2 is the structural representation of the another kind of nesa coating of the utility model.
Wherein: 10, the first PET base material layer; 20, ITO transparency conducting layer; 30, the first following layer; 40, the second PET base material layer; 50, anti-dazzle photosphere; 60, reinforced layer; 70, the second following layer.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
As shown in Figure 1, for a kind of nesa coating of the present utility model, it comprises the first PET base material layer 10, is attached to the ITO transparency conducting layer 20 of the first PET base material layer 10 lower surface, the first following layer 30, second PET base material layer 40 and anti-dazzle photosphere 50 is attached with from the bottom to top successively at the upper surface of the first PET base material layer 10, wherein, the refractive index of the first PET base material layer 10 is greater than the refractive index of the second PET base material layer 40.Above-mentioned each layer all has good light transmission, and anti-dazzle photosphere 50 is for promoting nesa coating viewing effect under high light.In above-mentioned nesa coating, first PET base material layer 10 and the second PET base material layer is set, electrically conducting transparent film strength can be improved greatly, to be applicable to the touch-screen of present stage electronic product, first following layer 30 is arranged between the first PET base material layer 10 and the second PET base material layer 40, not only can increase the bond strength of the first PET base material layer 10 and the second PET base material layer 40, plane of refraction can also be formed at the first following layer 30 with the face that the first PET base material layer 10 and the second PET base material layer 40 are combined simultaneously, be greater than the refractive index prerequisite of the second PET base material layer 40 in the refractive index of the first PET base material layer 10 under, better can strengthen the translucent effect of nesa coating
As shown in Figure 2, for another kind of nesa coating of the present utility model, be actually on the basis of nesa coating shown in above-mentioned Fig. 1, a reinforced layer 60 is provided with between anti-dazzle photosphere 50 and the second PET base material layer 40, second following layer 70 will be engaged togather both it is provided with between reinforced layer 60 and the second PET base material layer 40, this reinforced layer 60 can be the light-transmissive film material that intensity is larger, and it can further increase electrically conducting transparent film strength.
In nesa coating shown in above-mentioned Fig. 1 and Fig. 2, the thickness of ITO transparency conducting layer 20 is 25 ~ 35nm, the thickness of the first PET base material layer 10 is 45-60nm, the thickness of the second PET base material layer 40 is 80-90nm, the concrete thickness of each layer can be selected in above-mentioned number range, to guarantee under the prerequisite that electrically conducting transparent film-strength meets the demands, improving the light transmittance of nesa coating.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection range of the utility model claim.
