In an alternate embodiment, further include by flexible electrode assembly 320C be set to the first sub- touch-control module 30A and/Or second in sub- touch-control module 30B, the specific practice can refer to above description.
So far, the embodiment of the utility model can reduce the step of flexible cover board 70 is bonded by above-mentioned other embodiment i.e.Complete the touch panel of one of the utility model embodiment.
Touch sensing provided by the utility model, touch panel and preparation method thereof are carried by the first support plate and secondFlexible touch-control sensing component is formed on release film by the supporting role of plate, then is acted on by the reprinting of third support plate, can be withFlexible touch-control sensing component is attached on any on-plane surface and curved surface cover board, the touch panel being thusly-formed is lighter, thin,And cost of manufacture is relatively low.In addition, flexible touch-control sensing component uses the thin film sensor for including nanometer metal conducting layer, due toNanometer silver wire itself has good flexible resistance, therefore touch sensing provided by the utility model, touch panel can be used forFlexible touch-control and curved surface touch-control.In addition, since the material of bonding layer can be the active ink layer (Reactive with viscosityInk), there is no need to increase newly one layer of optical adhesive layer or gelatine layer can directly will be release after touch panel attach to it is any non-On the target support plate of plane, it can so that there is good optical characteristics, such as high-penetration while touch panel is more frivolousRate and low haze.
Touch sensing provided by the utility model has the electrode group of multilayer (two layers, three layers or more) with touch panelPart, the electrode assembly all have pliability, therefore are applicable to the attaching of plane or on-plane surface (such as surface with curvature)Surface, and the electrode assembly can should adjust its function because of different demands, to realize sensing function or electromagnetism with a greater varietyFunction of shielding makes touch sensing provided by the utility model and touch panel under conditions of flexible, tool ductility, has moreThe competitive advantage of product.In addition, touch sensing provided by the utility model and touch panel are because of the spy with flexible tool extensionProperty, therefore more it is applicable to bendable (bendable) display, folding (foldable) display or roll-type(rollable) display.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at thisWithin the spirit and principle of invention, any modification, equivalent substitution, improvement and etc. done should be included in the model that the present invention protectsWithin enclosing.
