Description
[technical field]
The utility model relates to touch technology field, particularly a kind of nano-silver thread large touch 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.
Follow in recent years contact panel in the rapid emergence of communications industry, particularly flourish in mobile communication industry, contact panel becomes the first-selected product of imaging display apparatus now at one stroke.The contact panel that utilization rate is the highest is mainly electric resistance touch-control panel and capacitance type touch-control panel, but user for controllability, the consideration of ease for use and appearance, can select capacitance type touch-control panel as its best preferred unit mostly.
Traditional large touch panel uses ITO (tin indium oxide) to make conducting layer electrode, but because the electric conductivity of ITO own is not good, the problems such as too high in resistance (ITO conductance is generally greater than 70 ohm/sheet resistance), make the sensitivity step-down of touch screen, response speed is slack-off, this problem is particularly evident after screen size is amplified, therefore when screen size exceedes after 14 cun or 15.6 cun, make electrode layer with ITO and be subject to certain restrictions that (if desired realizing sheet resistance is 100-500 ohm, conventionally can only be below 5 cun or 5 cun in panel size), and because ITO is expensive, cause adopting ITO higher as the price of the large touch panel of conducting layer electrode, the production cost of product is higher.Therefore at ATM and automatic vending machine, vehicle-mounted, on the large scale equipment such as aircraft, the application of capacitance type touch-control panel is less.Simultaneously, in the Trackpad of large-size, the length growth of electrode wires weakens the signal transmitting, the length that affects the sensitivity cabling of contact panel need increase with panel size, it is more and more that the quantity of cabling also can become, it is large that cabling region becomes, and viewing area reduces, and frame increases affects user's experience.
Along with the progressively increase of contact panel size, while being particularly applied to 15 cun of above panels, 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 large touch product for resistivity, cannot ensure electric conductivity that large touch panel is good and enough sensitivity, also cannot be applicable to the constantly development trend of low priceization of electronic product.
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, and exposure is developed, etching, stripping, numerous and diverse operation such as high-temperature baking, the high and length consuming time of manufacturing cost.
Therefore along with the progressively increase of contact panel size, ITO material can not be dealt with the demand in market gradually as conductive material and need to be eliminated gradually.Meanwhile, along with the requirement that people use is more and more higher, the simultaneously increase of manufacturing cost, also needs the smaller the betterly for the frame of contact panel or display, and even preferably surrounding does not all need to arrange, and is necessary therefore propose a kind of new solution.
[utility model content]
Obviously cause touch-control sensitivity low for overcoming existing ITO as the contact panel electricresistance effect of conductive layer making, large touch panel cabling is many, the large technical matters in coiling region, the utility model provides a kind of resistivity of large scale structure low, touch-control is highly sensitive, the contact panel of narrow frame.
The technical scheme that the utility model solves the problems of the technologies described above is: a kind of large touch panel is provided, it comprises a substrate, many nano-silver thread electrodes, be laid on described substrate, many nano-silver thread cablings, be connected corresponding with described nano-silver thread electrode tip, the same side nano-silver thread cabling is connected with touch control controller by least one flexible circuit board.

Preferably, further comprise a shielding line, be arranged at the periphery of described nano-silver thread cabling.
Preferably, the lead angle of described nano-silver thread cabling is arc.
Compared with prior art, the utility model large touch panel adopts nano-silver thread conductive layer to make conductive layer, first, it is low that nano-silver thread material itself has resistivity, light transmission rate is more than 85%, sheet resistance, in the superiority of 12-120ohm/sq, makes conductive layer have good electric conductivity, and the touch-control of contact panel is highly sensitive.Meanwhile, because nano-silver thread has good light transmission, and nano-silver thread trace width and spacing little, make the outer peripheral areas of contact panel narrow especially, thereby realize the design of contact panel Rimless, Rimless contact panel makes user visually openr, increase user and experience.Secondly, the unidirectional nano-silver thread conductive electrode of large touch panel of the present utility model at least connects a flexible electric circuit board by nano-silver thread cabling, therefore track lengths reduces, coiling region reduces, reduced the resistance of cabling, the touch-control that therefore can increase contact panel is sensitive simultaneously.Again, when the utility model contact panel cabling adopts nano-silver thread material, in the conductive layer of producing, easily exist nano-silver thread cabling to overlap bad situation.Therefore, adopt bilateral cabling design can strengthen signal transmission, prevent that the cabling that contact panel may occur in signals transmission from opening circuit and causing signal cannot be transferred to the situation on touch-control IC, improves the touch-control sensitivity of contact panel on one side.In addition, in the time adopting bilateral cabling design to be connected with electrode, the cabling on its each limit is connected with the flexible electric circuit board of its corresponding one end respectively, that is, bilateral cabling coordinates two flexible electric circuit boards to be connected to touch control controller can further to reduce the cabling quantity of the every end of electrode, can also increase the trace width of every end, therefore, it can effectively reduce the resistance of cabling, reduces processing procedure difficulty, anti-upward wiring overlap joint bad phenomenon.Again, in the time that the cabling of adjacent electrode is drawn from the different ends of electrode respectively, it can ensure that contact panel two ends cabling quantity all reduces by half, reduce monolateral cabling quantity, cabling region is reduced, due to the minimizing of cabling quantity, therefore can adopt wider trace width in addition, line impedence is reduced, and transmission speed increases; Next electrode cabling that is positioned at contact panel the same side is connected to one or two rich property circuit board of homonymy separately, thereby the track lengths of contact panel is shortened, thereby save the area in the shared cabling region of cabling, increase visual range, in the time that track lengths reduces, walk line resistance and also reduce, therefore accelerated the transmission speed of touching signals.Because the material of above-mentioned each cabling and conductive electrode is all selected nano-silver thread, therefore cabling can complete with conductive electrode in processing procedure in addition, has simplified processing procedure cost-saving.
