Embodiment
In order that those skilled in the art more fully understand the utility model, below in conjunction with the accompanying drawings and it is embodied
The utility model is described in further detail for mode.Obviously, described embodiment is only the utility model part
Embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not doing
Go out under the premise of creative work the every other embodiment obtained, belong to the scope of the utility model protection.
Term " first ", " second ", " the 3rd " " in the description and claims of this application and above-mentioned accompanying drawing
Four " etc. be for distinguishing different objects, rather than for describing specific order.In addition term " comprising " and " having " and
Their any deformations, it is intended that cover non-exclusive include.Such as contain the process of series of steps or unit, method,
The step of system, product or equipment are not limited to list or unit, but the step of may include not list or unit.
Present inventor has found that, for the touch-screen of DITO structures, generally use is double in the prior art by research
Face printing fine line silver cabling, or laser dry etching silver cabling, in conductive layer printed circuit for connection FPC.But screen printing
Dataller's skill, it is high to environmental requirement, during dirty dust all lines can be caused defect occur, and the silver of touch-screen walks Line To Line
Bar definition, uniformity requirement are higher, will certainly greatly increase manufacturing cost；In addition, the complicated lines effect that screen printing brushes out
Fruit is poor, undesirable to the cabling printing effect of complexity.Although the effect lines even results that laser-induced thermal etching goes out are good, and laser loses
The silver-colored cabling at quarter can be made thinner, but for etch the laser of silver paste line can penetrate the glass breakdown back side silver paste cabling, it is necessary to
Need to consider evasion when designing circuit, more peripheral space can be taken, cause touch platen edge wide；In addition, touch
Screen needs a circle shielding earth to reduce the interference in the external world, is inevitably laser etched onto, is unfavorable for touch-screen
Stability and reliability.
In consideration of it, the application prints silver paste cabling by one side using mode of printing, another side uses laser dry etching mode
Silver paste cabling is etched to prepare touch-screen, not only avoid and evade design problem, also improves the yield, stably of touch-screen
Property and reliability, also reduce manufacturing cost.
After the technical scheme of the utility model embodiment is described, detailed description below the application's is various unrestricted
Property embodiment.
Referring to Fig. 2, Fig. 2 is a kind of structure of the touch-screen of the utility model embodiment offer under embodiment
Schematic diagram, specifically it may include：
Conductive layer 201, sensor glassy layers 202 and protective layer 203.
Sensor glassy layers 202 are the capacitor dielectric of touch-screen, are distributed multiple sensors on the layer, can also for sodium calcium base or
The glass of silicon boryl substrate, certainly, or the glass of other materials, sensor are generally the sensor of recognizable position.
Conductive layer 201 has two layers of ITO layer 2011 and 2012, that is, forms DITO structures, and ITO layer is to pass through sputter coating
Mode transparent conductive film material is covered in surface, such as by magnetron sputtering, ion sputtering, certainly, can also use it
His mode；Transparent conductive film material such as individual layer or few layer graphene, or indium tin oxide material, can also be led using other certainly
Electric material.
Two layers of ITO layer 2011 and 2012 of conductive layer 201, be respectively arranged at sensor glassy layers 202 upper surface and
Lower surface, ITO structure are referred to shown in Fig. 3, and ITO surfaces have latticed pattern.
The edge distribution of ITO layer 2011 and 2012 has silver paste line layer, for connecting flexible PCB FPC, so as to
It is connected to touch-control IC.Silver paste line layer is layer printed circuit board or etched circuit layer, and ITO layer one side uses mode of printing
Cabling circuit is prepared, cabling circuit is simultaneously prepared using dry etching mode.That is the silver paste line layer in ITO layer 2011 is print
Brush circuit layer, then the silver paste line layer in ITO layer 2012 is then etched circuit layer, if the silver paste circuit in ITO layer 2011
Layer is etched circuit layer, then the silver paste line layer in ITO layer 2012 is then layer printed circuit board.It so can both avoid mode of printing
Due to process environments require it is too high and caused by production cost increase, can avoid again laser dry etching need evade design, so as to lead
Cause the increase of touch-screen area.
Layer printed circuit board can be that conductive silver ink watermark is formed on into ITO layer in a manner of silk-screen printing or ink jet printing.Wherein,
The technique of silk-screen printing is more suitable for large area, Flexible Production, and ink jet printing is more suitable for preparing when circuit precision is higher, specifically
Using which kind of typography, those skilled in the art more actual conditions can be chosen.Certainly, other printings can also be used
Mode.
Protective layer 203 is arranged in the ITO layer of the upper surface of sensor glassy layers 202, as shown in Figure 2 2011 it
On.Protective layer can be one layer of glass cover-plate, for protecting whole touch-screen, and play a part of to cover；Certainly, or other
The substrate of transparent material, the application do not do any restriction to this.
In the technical scheme that the application provides, conduction is laminated to be adopted using mode of printing printing silver paste cabling, another side
Be etched silver paste cabling with laser dry etching mode, effectively avoid laser breakdown sensor glassy layers etch other cablings and
Cause the phenomenon of open circuit, improve the yield of touch-screen, and improve the reliability and stability of touch-screen；Avoid laser
Cabling evades design, saves the space that touch-screen takes because evading design, makes so as to reduce production cost and user
With cost, the economic benefit having had.
In a kind of specific embodiment, referring to Fig. 4, the touch-screen may also include：
Optical transparent adhesive packed layer 204, it is arranged between protective layer and the sensor glassy layer.Optical transparent adhesive is one
Kind high transmittance, the acrylic material of low haze, for protective layer 203 and sensor glassy layers 202 to be bonded, when
So, can also be bonded using other modes, for example with optical cement, the composite of silica gel.By the way that further each layer is entered
Row bonding, touch-screen overall reliability and stability can be improved.
In another embodiment, the touch-screen may also include：
Insulating barrier, insulating oil is printed on the conductive layer in a manner of printing, for protecting the silver of the conductive layer
Starch circuit.
Due to not resistance to oxidation of silver itself, in order to improve silver paste and extraneous insulating properties, and upper and lower surface silver paste cabling
Insulate power, one layer of insulating oil can be brushed on the exposed ground of conductive layer, to improve the reliability of whole touch-screen and stability.
Insulating oil can be IR type height head insulating oil FR-IT-CK, or the semi-transparent insulating oil CR-18T-CR of IR types, certainly,
Also other kinds of insulating oil can be used.
It should be noted that the silver paste cabling used above can also be substituted using other conductive inks, such as copper slurry,
The copper raw material mixed solvent for preparing the Nanometer Copper chip architecture of sheet prepares conductive copper ink, due to the majority filled in existing silver paste
For Argent grain, electric conductivity is not very good, and fills the copper slurry of copper sheet structure, can lift the electric conductivity of conductive ink and resist
Bending property, it can also greatly save the production cost of whole touch-screen.
Each embodiment is described by the way of progressive in this specification, what each embodiment stressed be with it is other
The difference of embodiment, between each embodiment same or similar part mutually referring to.For dress disclosed in embodiment
For putting, because it is corresponded to the method disclosed in Example, so description is fairly simple, related part is referring to method part
