Description
Technical field
The invention belongs to touch screen technology fields, and in particular to a kind of touch screen structure for reducing silver-colored migration probability.
Background technique
The touch screen of membrane structure scheme at present, due to cost and sheet resistance, membrane material used is more and more by original
ITO be changed to nano silver material, for large scale (55 cun or more), requirement because of touch screen to resistance and transmitance, at present only
Nano silver membrane material can be selected, but is the master that current nano silver membrane material cannot be widely applied the problem of silver anode oxidation, silver migration
Want obstacle.
Silver migration refers in the wet environment there are Direct-current voltage gradient that hydrone is penetrated into be electrolysed to be formed containing silver conductor surface
Hydrogen ion and hydroxide ion, under the action of electric field, silver ion is migrated from high potential to low potential, and is formed cotton-shaped or complicated and confused
Shape extension positions in height and forms black oxidation silver on connected boundary.And nano-silver conductive membrane material is exactly to use Nano grade
The netted form homogeneous form of filamentary silver be coated in transparent membrane material and form conductive membrane material；For touch screen, in this conduction
Film surface etches the touch patterns of our needs, and channel forms the induced magnetic field needed；The production being made into for nano silver membrane material
Product, if humid environment, being powered on just would tend to occur silver migration and causes touch screen function bad.Nano silver membrane material at present
Manufacturer overcomes by adjusting their nano silver coating formulation, and nano silver is solidificated in membrane material surface as far as possible, but silver from
The migration of son still can be easy to appear problem because use environment influences.This is also the advantage that nano silver membrane material obviously has cost
And the market of ITO is not still replaced；But ito film material sheet resistance can not accomplish as nano silver is so low, for large scale touch screen,
ITO can not be supported.
Summary of the invention
The purpose of the present invention is to provide a kind of touch screen structures for reducing silver-colored migration probability, to solve to lead in the prior art
The drawbacks described above of cause.
The principle of touch screen based on the production of nano-silver conductive membrane material is it is found that silver migration needs to meet 2 conditions:
It (1) is moist environment；
(2) voltage difference of gradient.
Moist environment, this is the use environment of user, we cannot provide that client uses under which environment；So
The application is that silver migration is solved by solving the problems, such as the voltage difference of gradient.
Look first at the routing of layout of lower current capacitance plate: when touch screen is powered on, channel cabling just has electric entrance
And have voltage, but ground wire is ground connection, it is in the low potential of 0 state, always so as to cause touching between channel cabling and ground wire
Form a voltage difference；There is pressure difference, if client use environment is moist, is easy for caused by there is silver migration function not
It is good.
A kind of touch screen structure reducing silver-colored migration probability, including touch screen induction channel and pathway lead, the touch
Screen induction channels are connected to pathway lead, and the touch screen induction channel is made of nano silver material, and the touch screen induction is logical
The periphery in road is equipped with a peripheral channel, and the peripheral channel is connected to power supply, and power supply size is identical as touch screen induction channel,
Or the peripheral channel ground connection.
Preferably, the peripheral channel ground connection, and the distance between peripheral channel and touch screen induction channel D > 2mm, institute
Peripheral channel is stated using silver paste as electrocondution slurry.
Preferably, the peripheral channel is connected to power supply, and power supply size is identical as touch screen induction channel, peripheral channel
Periphery be additionally provided with a ground line, the ground wire is used as electrocondution slurry using silver paste, and peripheral channel is starched by copper or carbon slurry conduct is led
Plasma-based material.
Preferably, the peripheral channel is connected to power supply, and power supply size is identical as touch screen induction channel, then outer again
It is connected to electrostatic impedor.
Preferably, the distance between the ground line and peripheral channel D≤1mm.
Preferably, the pathway lead is used as electrocondution slurry using silver paste or copper slurry.
A kind of electronic equipment uses above-mentioned touch screen structure it includes touch screen body in the touch screen body.
Preferably, the electronic equipment is specially mobile phone, tablet computer, any one in touching-type monitor.
The present invention has the advantages that the present invention realizes the reduction of silver-colored migration probability using three kinds of modes: first is that adjustment touching
Screen the distance between induction channels and the peripheral channel of ground connection are touched, are adjusted to D > 2mm, specific distance can be according to each side IC
The supply voltage of case with the increasing of voltage, and increases distance, can reduce the probability for silver migration occur in this way；Second is that logical
It crosses and increases a peripheral channel between traditional touch screen induction channel and ground line, peripheral channel is connected to power supply, so that
Touch screen induction channel is always consistent for the voltage difference of periphery, therefore is not in the case where silver migrates；Third is that in tradition
Touch screen induction channel on the outside of increase a peripheral channel, peripheral channel is connected to power supply, so that touch screen induction channel pair
Voltage difference in periphery is always consistent, but also needs to be external to electrostatic impedor, to guarantee electrostatic attack occur when periphery
When, smoothly electrostatic can be guided and release is handled, to guarantee product not by electrostatic damage.
