Abstract
The invention provides a back adhesive type transparent conducting film. The conducting film is characterized in that a transparent conducting layer is sputtered on the front of a PET film; a PE protective film is covered on the transparent conducting layer; an optical adhesive is coated on the back of the PET film; and a heavy ion type film is covered on the optical adhesive. The conducting film has the following beneficial effects: the manpower gram of touch sensed pressure can be substantially reduced and the touch sensitivity is improved; the friction-resistant PET film is adopted, thus not only omitting the costly hardened coating originally coated on the film surface, but also substantially reducing the thickness of the film to achieve the aim of being light, thin, short and small; and the conducting film is widely applied to touch panels, electronic games, child teaching machines, smart 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 back glue type nesa coating.
Background technology
Nesa coating is a main material of making liquid crystal flat panel display (LCD), uses very extensive in the LCD field.Along with characteristics such as the consumer proposes higher requirement to LCD, and volume is little, in light weight, energy consumption is low, the screen reaction speed is fast more and more are embodied in the new display, give the new direction of researching and proposing of nesa coating.In addition, nesa coating can also be applied in fields such as the dizzy window, tank laser rangefinder of windshields such as aircraft, automobile, aerospace craft as the face heater, not only plays the heat insulation and heat control effect, and can also remove frost after the energising.Therefore, transparent conductive material has boundless market prospects.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of back glue type nesa coating is provided.
Purpose of the present invention is achieved through the following technical solutions:
The back glue type nesa coating, base material is the PET film, characteristics are: the front sputter of described PET film has transparency conducting layer, and the back of described PET film scribbles optical cement, is covered with heavy release film on the described optical cement.
Further, above-mentioned back glue type nesa coating wherein, is 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:
Adopt of the substrate of the PET film of rub resistance, fatigue durability, omitted and be coated on the expensive hardening coat in film surface originally as the sputter transparency conducting layer; Mode by vacuum splashing and plating forms transparency conducting layer; Being provided with heavy promptly getting promptly of product of release film realization at the PET film back side uses.When using this product, only heavy release film need be torn off, get one and be posted on the support base material as electricity level down, another is posted on the decoration panel as powering on level, scatters the insulation strong point between the two-stage and just can make contact panel.Whole compact, touch-control is highly sensitive; Combination by optical cement and heavy release film realizes promptly getting i.e. usefulness, and the user can shorten operation, and the defective products that reduces in the operation produces, and reduces manufacturing cost.
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 film, 2-transparency conducting layer, 3-PE diaphragm, 4-optical cement, the heavy release film of 5-.
Embodiment
As shown in Figure 1, back glue type nesa coating, base material are polyethylene terephtalate film 1, and the light transmittance of PET film 1 is more than 90%, and dielectric strength is 16.9KV/mm, but shielding of ultraviolet, and gas and vapor permeability are low; The front sputter of PET film 1 has transparency conducting layer 2, and the material of transparency conducting layer is nano indium tin metal oxide, wherein Ln

3Ratio be 9: 1; Be covered with PE diaphragm 3 on the transparency conducting layer 2, the back of PET film 1 scribbles optical cement 4, optical cement 4 light transmittances＞99%, mist degree＜1%, high temperature resistant, high humidity; Be covered with heavy release film 5 on the optical cement 4.
Adopt of the substrate of the polyethylene terephtalate film 1 of rub resistance, fatigue durability as the sputter transparency conducting layer, omitted and be coated on the expensive hardening coat in film surface originally, but also the thickness of PET film can be thinned to 50 μ m significantly from customary 188 μ m, to satisfy compact purpose; Mode by vacuum splashing and plating forms transparency conducting layer 2, sputter nano indium tin metal oxide, and thickness of coating is even, and resistance value reaches 400 Ω; Being provided with heavy release film 5 promptly getting promptly of product of realization at PET film 1 back side uses.When using this product, only heavy release film 5 need be torn off, get one and be posted in support base material (PC or glass) and go up as electricity level down, another is posted on the decoration panel as powering on level, scatters the insulation strong point between the two-stage and just can make contact panel.Whole compact, touch-control is highly sensitive; Combination by optical cement and heavy release film realizes promptly getting i.e. usefulness, and the user can shorten operation, and the defective products that reduces in the operation produces, and reduces manufacturing cost.
The people that the back glue type nesa coating can reduce the touch-control pressure-sensitive significantly makes every effort to overcome number, thereby improve touch-control sensitivity, adopt the PET film of wear-resisting difference simultaneously, not only omitted and be coated on the expensive hardening coat in film surface originally, but also the thickness that can reduce film significantly is to satisfy compact purpose.The present invention promptly gets i.e. usefulness, 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. back glue type nesa coating, base material is the PET film, it is characterized in that: the front sputter of described PET film has transparency conducting layer, and the back of described PET film scribbles optical cement, is covered with heavy release film on the described optical cement.
2. back glue type nesa coating according to claim 1 is characterized in that: be covered with the PE diaphragm on the described transparency conducting layer.
