Description
Technical field
The present invention relates to touch screen transparent conductive film and preparation method thereof, this conducting film is transparent under the visible light environment, has conductivity, is suitable for touch-screen, liquid crystal display, electroluminescence demonstration, electromagnetic wave shielding and transparency electrode.
Background technology
Along with the touch-screen commodity enter huge numbers of families, touch quality is required more and more higher, to compete more and more fiercely, cost performance is even more important.The kind of touch-screen has infrared optics mode, ultrasonic wave mode, capacitive way and Impedance Membrane mode etc., because the Impedance Membrane mode is simple in structure, the cost performance excellence, rapidly popularize in recent years, the touch-screen of Impedance Membrane mode uses in consumer products in a large number, as touch-screen mobile phone, game machine, dictionary, translating machine etc., in the industry control product, obtained widely applying as auto navigation, photocopier display screen, plant equipment control flow, automatic teller machine, public sector's ticket machine and double screen touch screen computer.
The impedance type touch-screen has the transparency and conductivity, be suitable for the transparency electrode of touch-screen and other display screens, length direction and Width evenly distribute, sheet resistance is a transparent conductive laminate, dispose by the partition subtend with the glass that has transparent conducting film, electric current flows through transparent conductive laminate, and measures the voltage on glass that has transparent conducting film.By push the operation of transparent conductive laminate by finger or pen etc., make itself and the glass contact that has transparent conductive film, the position that this contact portion energising just can be experienced this contact portion is so it is relevant with transparent conducting film to improve near the pen input durability of the peripheral part of touch-screen.
The electrically conducting transparent film base material is PETG (PET) or poly-naphthalene dicarboxylic acid glycol ester (PEN), flexibility, and processability, impact resistance excellence, light weight, easily cleaning surfaces is handled, and is the nesa coating preferred substrates.But because such substrate preparation nesa coating, the light reflectivity on transparent membrane surface is big, and it is transparent poor to exist, and scratch property and resistance to bend(ing) are poor, scratches back resistance and increases or produce breaking phenomena.Conducting film is a pair of film that is oppositely arranged by partition, each other by pushing to get ready and carry out touch operation from a side's wherein screen board side, and has a powerful contact, thereby the opposing wear properties is descended, just because of get characteristic ready, conducting film just exists the defective of poor durability and lifetime.
And, above-mentioned nesa coating also can produce Newton's ring because of film expands and curls, cause identity poor, at these problems and conform poor, scratch and to cause resistance to increase, produce problems such as broken string, light scattering layer is set and layered product inhibitory reflex light obtains the high reliability nesa coating as the Japanese CN1729410A of Teijin Ltd.The Japan CN1531736A of Toyo Boseki K.K is provided with inorganic hardened layer between nesa coating, by indium tin composite oxides or tin antimony composite oxides, suppress electric current sheet resistance that eddy current produces and distribute unstable.Japan electrician CN101010661A, CN101127255A, CN1947204A adopt dry process to form SiO
2Layer forms four layers of two-fold 2 mechanism's nesa coating of high index of refraction.
Summary of the invention
The present invention is for a kind of high-performance touch screen transparent conductive film is provided, and described nesa coating has the excellent chemical medicine, and wear-resisting wiping is damaging, resistance to water, and can suppress not to be prone to Newton's ring by curling that expansion causes, the touch-screen with stable identification nesa coating can be provided.
Nesa coating of the present invention comprises: anti-reflection layer that the base material upper side is coated with successively and hard conating, and the ITO conductive layer of base material downside.
