The most important touch-control layer material of screen is shown for non-curved LCD and OLED etc..But the brittle speciality of ITO, is not suitable for doing deep camber
The flexible touch control layer that even can arbitrarily bend, and transparent conductive film valence cost is high, about accounts for entire touch screen at present
The cost of curtain industry upstream materials part 30%-40%, especially " indium " belong to limited rare metal, therefore, the oxidation of indium tin
It is a kind of inevitable development trend that object, which is substituted,.
Nano silver technology is that silver ink material is coated on substrate, and nano-silver thread conduction is made using radium-shine technology
Layer.Its advantage is that yield is high, line width is small, good conductivity and resistance to around folding.Compared to metal grill, nano silver material has lesser song
Rate radius, and resistance variations when being bent are small, therefore is suitble in the high-resolution such as mobile phone and bracelet the reason of adding line width
It uses, but nano silver technical costs is high, limits its application in terms of mobile phone and bracelet.
The light transmittance of grapheme material compares traditional material, and light transmittance is higher, so that the display of graphene touch screen is more
It is clear to add；Conduction aspect, the resistivity of graphene is also lower than traditional material resistivity, so that graphene touch screen touch-control gets up
It is sensitiveer, but the conductive capability of graphene is also less desirable, limits its further application.
It is, therefore, desirable to provide a kind of more applicable flexible touch screen, to solve the above problems.
Utility model content:
The better flexible touch screen of lower and conductive capability the purpose of the utility model is to provide a kind of cost.
To achieve the above object, the utility model uses following technical scheme:
A kind of flexible touch screen provided by the utility model, comprising: flexible cover plate, the flexible cover plate side are sequentially arranged
Flexible substrate and display screen, the flexible cover plate, flexible base board and display screen form multi-layer compound structure, the flexible cover plate
Side far from the flexible base board is provided with hardening coat, and a side surface of the flexible base board towards the flexible cover plate is set
It is equipped with conductive circuit layer, the conductive circuit layer is graphene nano silver wire composite conductive film, and the flexible cover plate is led with described
The fitting of electric line layer, the flexible base board other side is bonded with the display screen.
The hardening coat with a thickness of 2-10 μm.
The flexible base board is PET film.
The display screen is AMOLED display panel.
The flexible cover plate is fitted with the conductive circuit layer by OCA optical cement, the flexible base board other side with
The display screen is fitted by OCA optical cement.
A kind of flexible touch screen of the utility model the utility model has the advantages that the touch screen of the utility model be multi-layer compound structure,
Floor graphene nano silver wire composite conductive film in conventional conductive line road is replaced, silver and graphene are combined, not only had
Effect control cost, and optimizes electric conductivity, while conductive circuit layer and flexible cover plate after solidify and display screen pass through OCA light
It learns sticker to be integrated, the generation of bubble when effectively reducing fitting, thus guarantee the higher yield of product, structure novel,
It is practical.
