Line touch screen and manufacture method thereof.
Background technology
Touch screen, as a kind of man machine interface window, can optimize the convenience of man-machine communication significantly, preferably carry
For Consumer's Experience.Capacitive touch screen is widely used in consumer electronics product, such as before making: smart mobile phone, panel computer
Deng equipment.And along with these products popularization degree more and more higher, and manufacturing process is more and more ripe, comes for module factory
Saying, a kind of easier processing technique, the processing method that a kind of cost is lower reforms into the hard requirement of module factory.Arc touch-control
Product, flexing or the touch-control product that can arbitrarily fold can will become the developing direction of next-generation technology of touch screen, along with
The raising that family experience requires, these all will become mainstream demand.
The main flow transparent conductive material of capacitance present formula touch screen is ITO, and its preparation flow is as shown in Figure 2.Though this material
So there is the characteristics such as high light transmittance, low colour cast, and suitable conductive resistance, substantially can meet the function of common touch screen
Requirement, but the problem that ITO itself yet suffers from much being difficult to overcome.Such as (1) fragility is big, frangible, easily split so that it is adding
For producing the management and control of line relatively strictly during work, poor fault tolerance, extra increase management and control cost；And due to its mechanicalness
Can the problem of difference so that ITO cannot realize making flexible, folding touch product；(2) ito film is before the course of processing
Carry out high-temperature process, need recrystallization that its electric conductivity just can be made to meet and use requirement, and on the one hand high-temperature process increases into
This, the most also may require that the base material of carrying ITO possesses resistant to elevated temperatures requirement, and this most also can increase cost,
And high-temperature process can make base material produce deformation, certain difficulty also can be increased for follow-up processing and design.
For the drawbacks described above of prior art, find suitable ITO substitution material and more cost-effective processing side
Method just becomes current urgent problem.
Summary of the invention
For the defect of prior art, it is an object of the invention to by a kind of copper facing nano-silver thread touch screen and preparation thereof
Method, it is achieved that capacitive touch screen can flexing, folding function, and in terms of processing, due to copper facing nano-silver thread
The characteristic of conducting film, also achieves the work flow without high temperature process, is greatly saved processing cost.
In order to realize above-mentioned technical purpose, the technical scheme is that a kind of copper facing nano-silver thread touch screen, including lid
Plate, described cover plate is glass, sapphire, PMMA hard material, or be PET, tempering flexible membrane flexible material, at described lid
The side of plate stacks gradually structure and is provided with Optical transparent adhesive, touch sensing element, anisotropic conductive adhesive, flexible PCB, described
Cover plate is mutually bondd by described Optical transparent adhesive with described touch sensing element, integrated various electricity above described flexible PCB
Sub-device, described flexible PCB is connected with described touch sensing element by anisotropic conductive adhesive, and both combine and realize touching
Touch positioning function.
Above-mentioned touch sensing element is to process, by gold-tinted processing procedure, the copper facing nano-silver thread conducting film drawn.Above-mentioned is soft
Property circuit board top can integrated various electronic devices, such as: IC, electric capacity, resistance, diode etc..
A kind of manufacture method of copper facing nano-silver thread touch screen, including following preparation process:
A, use copper facing nano-silver thread conducting film；
B, by gold-tinted processing procedure by copper facing nano-silver thread conducting film make touch pattern, produce described in claim 1
Touch sensing element；
C, empty the flexible PCB bindings bit in Optical transparent adhesive according to design, and IR hole and preposition camera hole；
D, the Optical transparent adhesive emptied is posted on touch sensing element；
Flexible PCB is connected by E, use anisotropic conductive adhesive with the Pin foot of touch sensing element；
F, laminating cover plate.
Above-mentioned copper facing nano-silver thread conducting film, its copper conductive layer can be copper or copper alloy；Above-mentioned anisotropic conductive adhesive
Interior gold goal particle diameter is less than 5um.
The present invention is equivalent to nano-silver thread layer as transparency conducting layer, and copper conductive layer is just when the cabling for ultralow sheet resistance
Layer, nano-silver thread has low square resistance, the resistance to advantage around folding relative to the ITO material of main flow, and plates on nano-silver thread layer again
Copper then can simplify work flow during follow-up making contact panel, is greatly saved processing cost；And nano-silver thread can also be solved
Conducting film starch instability in electrical contact or bad etc. the problem of adhesion with silver；And also can greatly letter in terms of processing procedure
Change production link, it is easier to realize automated production.
Disclosed by the invention is a kind of brand-new touch screen and manufacture method thereof, and the present invention uses a kind of novel transparent lead
Electric material---copper facing nano-silver thread conducting film.The present invention can be greatly simplified making step, improves production efficiency, improves and produces
Product yield, and the touch screen made can realize the bending property of destroying or force to yield that main flow ITO product cannot realize, and has important meaning
Justice.Based on this, the present invention is widely used in various touch screen and manufacture method thereof.
