Description
Technical field
The utility model relates to touch screen technology, is specifically related to flexible touch screen conducting film.
Background technology
At present, the base material that touch screen uses can roughly be divided into two classes: a class is glass; Another kind of is organic polymer.Substrate of glass has low birefringence, low-expansion coefficient, low roughness, high-dimensional stability, the plurality of advantages such as high temperature resistant, but the touch-screen taking glass as substrate fabrication is easily cracked, and cannot realize bending fold, along with electronic product is towards lightness, miniaturization development, performance to base material has proposed new demand, need to have the new material that can make up substrate of glass deficiency to occur.
Organic polymer is the good flexible base material of a class, has good flexibility and cost lower, and applicable R-TO-R technique is produced in enormous quantities.Organic polymer is mainly divided into according to its different performance: thermoplasticity half hitch crystal formation, thermoplasticity non-crystalline type and high glass transition temperature material.Thermoplasticity half hitch crystal formation mainly contains PET, PEN material; Thermoplasticity non-crystalline type mainly contains PC, PES material; High glass transition temperature material mainly contains PAR, PCO, PI etc., is comparatively extensively thermoplasticity hypocrystalline shaped material and use at present.
Touch-screen taking organic polymer as base material has had extensive use, but have that transmitance is low, edge lead-in wire makes by traditional vacuum plating, lead-in wire easily comes off, not the problem such as resistance to bending.
Utility model content
The purpose of this utility model is to propose a kind of flexible touch screen conducting film, and it can solve the problem that transmitance is low.
In order to achieve the above object, the technical scheme that the utility model adopts is as follows:
A kind of flexible touch screen conducting film, it comprises from the bottom to top stacked successively organic polymer layers, niobium pentaoxide membrane dielectric layer, silicon dioxide adhesive linkage, ITO transparency conducting layer and trace layer, in described trace layer, offer groove, in described groove, be filled with conductive nano metal.
Preferably, described organic polymer layers is PET(Polyethylene terephthalate) layer or PEN(PEN) layer.
Preferably, the ranges of indices of refraction of described niobium pentaoxide membrane dielectric layer is 2.0-2.5.
Preferably, the ranges of indices of refraction of described silicon dioxide adhesive linkage is 1.4-1.7.
Preferably, described ITO(Indium Tin Oxides, indium tin oxide) ranges of indices of refraction of transparency conducting layer is being 1.9-2.2.
Preferably, the thickness range of described niobium pentaoxide membrane dielectric layer is 100-150 dust.
Preferably, the thickness range of described silicon dioxide adhesive linkage is 500-700 dust.
Preferably, the thickness range of described ITO transparency conducting layer is 500-1500 dust.
Preferably, described trace layer is OC material layer.
Preferably, the thickness range of described trace layer is 1-3um.
The utlity model has following beneficial effect:
Organic polymer layers is as substrate, between substrate and ITO transparency conducting layer, be coated with niobium pentaoxide membrane dielectric layer and silicon dioxide adhesive linkage, effectively improve the transmitance of product, simultaneously, utilize transfer printing nano-level conducting metal, form conductive lead wire, efficiently solve traditional vacuum plating and make lead-in wire, lead-in wire easily comes off and the problem such as resistance to bending not.
Brief description of the drawings
Fig. 1 is the structural representation of the flexible touch screen conducting film of the utility model preferred embodiment.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further.
As shown in Figure 1, a kind of flexible touch screen conducting film, it comprises from the bottom to top stacked successively organic polymer layers 10, niobium pentaoxide membrane dielectric layer 20, silicon dioxide adhesive linkage 30, ITO transparency conducting layer 40 and trace layer 50, in described trace layer 50, offer groove (figure does not mark), in described groove, be filled with conductive nano metal 60.Shown in organic polymer layers 10 as substrate.
The organic polymer layers 10 of the present embodiment is preferably PET(Polyethylene terephthalate) layer or PEN(PEN) layer.The highlighted PET polyester film that specifically can select transmitance to be greater than 90%.
The ranges of indices of refraction of the niobium pentaoxide membrane dielectric layer 20 of the present embodiment is 2.0-2.5, and its thickness range is 100-150 dust.
The ranges of indices of refraction of the silicon dioxide adhesive linkage 30 of the present embodiment is 1.4-1.7, and its thickness range is 500-700 dust.
