Abstract
The invention provides a Newton-ring-resistant transparent conductive composite plate. For the plate, a base plate is a poly(ethylene terephthalate) (PET) plate, wherein a hard coating is coated on the front side of the PET plate, and a polyethylene protective film is covered on the hard coating; and a Newton-ring-resistant coating is coated on the back of the base plate, and a transparent conductive layer is sputtered on the Newton ring resistant coating, and a PE protective film is covered on the transparent conductive layer. The Newton-ring-resistant transparent conductive composite plate can effectively eliminate the phenomenon of Newton ring, has excellent surface hardness, scratch resistance, dimension stability and profile processability, and can be widely applied to the aspects of touch panels, electronic game machines, children electronic tutors, intelligent mobile phones, tablet personal computers and the like.
Description
Technical field
The present invention relates to a kind of conducing composite material, relate 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 objective of the invention is to overcome the deficiency that prior art exists, a kind of Newton's ring-resisting electrically conducting transparent composite board is provided.
Purpose of the present invention 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 solution of the present invention 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 solution of the present invention is described further:
Fig. 1: schematic cross-section of the present invention;
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, 5PE diaphragm, 6PE 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
2O
3Ratio be 9: 1.
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 present invention 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 invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. Newton's ring-resisting electrically conducting transparent composite board, base material is the PET plate, it is characterized in that: 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.
