Abstract
The utility model provides a transparent conductive composite plate resisting a Newton ring. A PET (Polyester) plate is used as a substrate; the front side of the PET plate is coated by a hardening coating which is coated by a PE (Poly Ethylene) protecting film; the back side of the substrate is coated by a Newton ring resistant coating; and a transparent conductive layer is sputtered on the Newton ring resistant coating and is coated by the PE protecting film. By using the transparent conductive composite material resisting the Newton ring, the Newton ring phenomenon can be effectively eliminated; and meanwhile, the transparent conductive composite plate has favorable surface hardness, scratching resistance, size stability and special-shaped processing performance, and is widely applied to touch panels, electronic game machines, infant teaching machines, intelligent mobile phones, tablet computers, and the like.
Description
Technical field
The utility model relates to a kind of conducing composite material, relates in particular to a kind of electrically conducting transparent composite board of Newton's ring-resisting.
Background technology
Along with the development of computer, communication and consumption electronic product with popularize, display contact panels such as liquid crystal indicator have become indispensable a kind of instrument in modern's life.Mostly known display contact panel is to be made up of two electrode base boards, electrode base board comprises sandwich constructions such as glass plate, resin plate, thermal plastic high polymer film and conductive layer, this sandwich construction tends to because film interference shows light and dark donut on display, it is the Newton's ring phenomenon, the display quality of the generation meeting interferoscope of Newton's ring phenomenon, influence its market admittance degree, therefore how to avoid this Newton's ring phenomenon in display, to occur receiving much attention.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of Newton's ring-resisting electrically conducting transparent composite board is provided.
The purpose of this utility model is achieved through the following technical solutions:
Newton's ring-resisting electrically conducting transparent composite board, base material is the PET plate, characteristics are: the front of described PET plate scribbles hardening coat, is covered with the PE diaphragm on the described hardening coat; The back side of described substrate scribbles the Newton's ring-resisting coating, and sputter has transparency conducting layer on the described Newton's ring-resisting coating.
Further, above-mentioned Newton's ring-resisting electrically conducting transparent composite board, wherein: be covered with the PE diaphragm on the described transparency conducting layer.
The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in:
Have the coating of the optical microstructures that prevents that Newton's ring from producing in the substrate backside spraying, effectively contain the generation of Newton's ring, obviously improve the display quality of display; Establish hardening coat in the base material front, improve the surperficial scratch resistance and the chemical resistance of product, prolonged the service life of product greatly; Conductive layer directly on the Newton's ring-resisting coating mode by vacuum splashing and plating form, saved the step of using optical cement to paste conducting film, provide cost savings.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: schematic cross-section of the present utility model;
The implication of each Reference numeral among the figure:
The 1-PET plate, 2-hardening coat, 3-Newton's ring-resisting coating, 4-transparency conducting layer, 5-PE diaphragm, 6-PE diaphragm.
The specific embodiment
As shown in Figure 1, Newton's ring-resisting transparent conducting Composite material, its substrate are PETG plates (PET plate) 1, scribble hardening coat 2 in the front of PET plate 1, and hardening coat 2 is provided with PE diaphragm 5; Scribble Newton's ring-resisting coating 3 at the back side of PET plate 1, sputter has transparency conducting layer 4 on the Newton's ring-resisting coating 3, and transparency conducting layer 4 is provided with PE diaphragm 6.The light transmittance of PET plate 1 is more than 90%, and dielectric strength is 16.9KV/mm, but shielding of ultraviolet, and gas and vapor permeability are low.Case hardness after hardening coat 2 sclerosis reaches more than the 3H/750g, light transmittance＞90%, and the hardening process of hardening coat is to finish under the condition of illumination; Newton's ring-resisting coating 3 and hardening coat 2 can be by any enforcements in roller coat or the spraying method; The material of transparency conducting layer 4 is nano indium tin metal oxide, wherein Ln
2O
3And Sn

Adopting PETG (PET) is substrate, under the prerequisite of giving the material high light transmittance, the possibility that provides composite to be processed into different structure is coated with the hardening coat of special substance on pet substrate, can improve the scratch resistance of product, prolong the service life of product; Be coated with the Newton's ring-resisting coating at the back side of pet substrate and can contain effectively that substrate and its transparency conducting layer produce the oily oil shadow of Newton's ring, improve display quality; Transparency conducting layer uses the mode sputter nano indium tin metal oxide of vacuum splashing and plating, saves the step of pasting conducting film by optical glue, provides cost savings.
The utility model can be widely used in aspects such as contact panel, electronic game machine, childhood teaching machine, smart mobile phone, panel computer.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
