[technical field]
The present invention relates to technical field of touch control, a kind of especially contact panel.
[background technology]
Touch control device is subject to the favor of telecommunications industry gradually because of advantages such as its convenient operation, imaging are effective, function diversification, and is widely used on the products such as information system equipment, home appliance, communication apparatus, personal portable.
With contact panel in recent years in the rapid emergence of communications industry, flourish particularly in mobile communication industry, contact panel becomes the first-selected product of imaging display apparatus now at one stroke.Contact panel mainly electric resistance touch-control panel and the capacitance type touch-control panel that utilization rate is the highest, but user is for controllability, the consideration of ease for use and appearance, and capacitance type touch-control panel mostly can be selected as its best preferred unit.
At traditional intelligence mobile phone, as in the capacitance type touch-control panel of iphone etc., the material of touch control electrode is generally tin indium oxide (referred to as ITO).The transmittance of ITO is very high, and electric conductivity is better.But ITO is expensive, ITO is more crisp, pliability is poor, easily rupture time bending and cause dysfunction, even if be destroyed bending being also very easy to running into less physical stress, ITO conductance is generally greater than 70 ohm/sheet resistance, along with the progressively increase of contact panel size, when being particularly applied to the panel of more than 15 cun, the defect of ITO is more and more outstanding, wherein the most obvious defect is exactly that the surface resistance of ITO is excessive, ITO cannot meet the requirement of current touch-control product for resistivity, the electric conductivity that large touch panel is good and enough sensitivity cannot be ensured, also the development trend of the continuous low priceization of electronic product cannot be applicable to.
In addition, in manufacture method, ITO originally needs vacuum chamber, higher depositing temperature and/or high annealing temperature to obtain high conductance, causes the integral manufacturing cost of ITO very expensive.In processing procedure, ITO generally adopts sputter and gold-tinted light blockage coating, exposure, development, etching, stripping, numerous and diverse operation such as high-temperature baking, the high and length consuming time of cost.
Traditional ITO contact panel adopts metal routing usually, and therefore touch control electrode and metal routing will complete by a point twice processing procedure, so processing procedure is complicated and cost is higher; When panel size increases, track lengths need increase with the size of panel, and then causes trace resistances to become large, makes touch-control sensitivity decrease; Exist in addition and cause signal interruption, so new improvement design will be very necessary when fracture appears in part cabling.

Refer to Figure 13, for the schematic perspective view of eighth embodiment of the invention contact panel 70, this contact panel 70 is substantially identical with the structure of the first embodiment, difference is only: arrange a levelling blanket 715 at the second conductive layer 705 upper surface, certainly, also levelling blanket 715 can be set at the first conductive layer 703 lower surface.
Levelling blanket 715 is positioned at the second conductive layer 705 upper surface, or preferably, the second conductive layer 705 is partially submerged in levelling blanket 715 in a thickness direction.Nano-silver thread conductive layer 805 is coated on second substrate 707 upper surface and forms the second conductive layer 705.Nano-silver thread 801 can not tile equably and overlap more preferably, makes poor flatness, simultaneously due to phenomenon that the harmful effect nano-silver thread 801 that laps one another between nano-silver thread 801 is upturned.By applying levelling blanket 715 on the second conductive layer 705, and after certain PROCESS FOR TREATMENT, the overlap joint area between nano-silver thread 801 can be made to increase thus improve the conductance of nano-silver thread 801 and reach good surface smoothness.
Thus, contact panel 70 rhythmo structure from top to bottom of the present embodiment is followed successively by first substrate 701, the first conductive layer 703, bonding coat 709, levelling blanket 715, the second conductive layer 705 and second substrate 707.

Refer to Figure 14, contact panel 10,40,50,60,70 and 90 of the present invention can be used as touch sensible element in multiple device, is made into display device 80.Such as, when being used in LCD display by first embodiment of the invention contact panel 10, be disposed with polaroid 811 in the below of contact panel 10, upper substrate 813, liquid crystal layer 815, infrabasal plate 817, lower polaroid 819.Upper outside except being used in LCD display herein, can also be used on plasma display, on color flat panel display, on optoelectronic device and similar products.Wherein, wherein one deck electrode of this contact panel 10,40,50,60,70 and 90 can be formed in polaroid 811 or lower polaroid 819, or upper substrate 813, or on infrabasal plate 817.
Compared with prior art, first, first conductive layer 103 and/or second conductive layer 105 of contact panel 10 of the present invention by adopting nano-silver thread conductive layer 805 to be made into contact panel 10, due to nano-silver thread 801 material itself, to have resistivity low, light transmission rate is more than 85%, sheet resistance 12-120ohm/sq, contact panel 10 of the present invention is made to have the features such as good electric conductivity, ensure that the touch-control of contact panel 10 is highly sensitive, especially in particularly evident to the lifting of sensitivity in the middle of large-sized contact panel.Meanwhile, because nano-silver thread 801 has good light permeability, and trace width and spacing little, make the non-touch-control region 131 of contact panel 10 narrow especially, thus Rimless contact panel 10 be achieved.Rimless contact panel 10 makes user visually openr, and adding users is experienced.Secondly, the invention provides a kind of contact panel 10, and can increase by a levelling blanket in this contact panel layer structure, this levelling blanket makes the overlap joint between nano-silver thread 801 become good, thus conductance is effectively ensured, and the surface smoothness of contact panel 10 is greatly improved.
Again, contact panel 10 of the present invention can adopt bilateral cabling to improve the first conductive electrode cabling and the second conductive electrode cabling material when adopting nano-silver thread or other conductive metal material because make, use or the reason such as other improper operation and the cabling that is easy to produce overlaps bad situation, thus reinforcement signal transmission, one side open circuit of cabling makes signal cannot be transferred to situation on touch-control IC to prevent contact panel 10 from may occur in signals transmission, improves the touch-control sensitivity of contact panel.In addition, due to the size effect of its Nano grade, make it have excellent light transmission and flexible resistance, therefore be more suitable for the design needs for the more hommization products in present market, as wearable type products such as motion bracelets.On processing procedure, owing to adopting nano-silver thread 801 as cabling material, the first conductive electrode 121 and corresponding cabling 161 thereof can be made like this, 163, second conductive electrode 123 and corresponding cabling 165,167 thereof complete in processing procedure, simplify manufacture craft, consuming time few, cost is low.In addition, the first conductive electrode cabling 161,163 and the second conductive electrode cabling 165,167 are divided into multiple routing layer, the cabling quantity of each routing layer is reduced relatively, the area in the non-touch-control region shared by lead-in wire can be saved, realize the object of narrow frame design.And, in limited frame region, because the conductive electrode number of leads of each routing layer can reduce relatively, therefore suitably can strengthen the width between contact conductor and spacing, be convenient to arrangement and the making of conductive electrode lead-in wire, increase fine ratio of product.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within principle of the present invention, equivalent replacement and improvement etc. all should comprise within protection scope of the present invention.
