With not existing together of traditional four corner electrodes, the present invention is the parallel pole that has designed many groups symmetry, and the scanning of using different sequential, carries out the single-point location of zones of different, but and then reaches the purpose of detecting multi-point touch.For example, adopt two pairs of X-axis parallel poles and two pairs of Y-axis parallel poles, can detect 4 touchings of four blocks; Adopt three pairs of X-axis parallel poles and three pairs of Y-axis parallel poles, can detect 9 touchings of nine blocks; Adopt two pairs of X-axis parallel poles and three pairs of Y-axis parallel poles, then can detect 6 touchings of six blocks.By that analogy, if M is arranged to the X-axis parallel pole, N can detect MxN block to the Y-axis parallel pole, carries out the touch detection that MxN is ordered, and M, N are at least 1 integer.
Adopt the benefit of analog contact panel to be, its technology is skillful, production yield height, and cheap.Under the situation that present precision day by day increases, the matrix type parallel electrode array of the present invention of arranging in pairs or groups again can be realized high-precision multi-point touch detecting.It compares with the contact panel of mainly taking PCT as multi-point touch detecting usefulness now, and great superiority of effectiveness is arranged.
In addition, matrix type parallel electrode structure of the present invention only need use one deck conductive layer can realize capacitive touch detection, and not need two conductive layers, can significantly reduce production costs.
Please refer to Fig. 4, it is the contact panel 100 first illustrations intention of matrix type parallel electrode array of the present invention, and it is the application examples of the parallel pole matrix of employing 3x3, can scan and obtain exactly the touching result of 9 blocks as shown in FIG..At first explanation is, the present invention can use identical electrode structure, produces the parallel pole matrix of MxN, and the embodiment of Fig. 4 is only for wherein a kind of, according to following exposure of the present invention, as the embodiment that can directly produce the various different blocks of MxN matrix.Below, will describe in detail.
The contact panel 100 of Fig. 4 is formed at substrate (not marking) by conductive layer 110.On conductive layer 110, then be formed with the X-axis parallel pole of 3 pairs of symmetries and the Y-axis parallel pole of 3 pairs of symmetries, be respectively Y-axis parallel pole YU-01/YD-01, YU-02/YD-02, YU-03/YD-03, and X-axis parallel pole XR-01/XL-01, XR-02/XL-02, XR-03/XL-03, it is formed on the edge of conductive layer 110.And the structure of each parallel pole is all same or similar, all can provide scanning area one uniform electric field.Parallel electrode array of the present invention is to apply to electric resistance touch-control panel (Resistive), and perhaps surface capacitance type contact panel (SCT) etc. has the demander that the equipotential field forms.
Wherein, 3 couples of Y-axis parallel pole YU-01/YD-01, YU-02/YD-02, the two-end-point of YU-03/YD-03 have gone here and there resistance R 1 respectively; X-axis parallel pole XR-01/XL-01, XR-02/XL-02, the two-end-point of XR-03/XL-03 have gone here and there resistance R 1 respectively.The resistance R 1 at each parallel pole two ends then is connected on the series connection electrode chains 120.Each parallel pole all disposes a series connection electrode chains 120, and sees through outside voltage control division, via battery lead plate YU-11, YD-11, YU-12, YD-12, YU-13, YD-13, XR-11, XL-11, XR-12, XL-12, XR-13, XL-13 sees through lead and transmits control voltage again to each parallel pole, to carry out the control of voltage output, allow the contact region, inside of conductive layer 110 form as 9 blocks among the figure, to carry out the detecting that scans of touch-control respectively.
Wherein, parallel pole and lead can adopt silver-colored lead or other metal, as preferable metals of electric conductivity such as molybdenum aluminium molybdenum layer, chromium or other, better person, the silver-colored lead that can adopt the high temperature silver slurry more than 500 ℃ to make, it can make lead narrow with the width of reduction frame effectively, and reaches low resistance (energy consumption be'ss few) effect, and can make that shake-up edges of regions linear support power is good.
Because the resistance value of silver-colored lead is all identical, approaches 0 nurse difficult to understand, so, by battery lead plate YU-11, YD-11, YU-12, YD-12, YU-13, YD-13, XR-11, XL-11, XR-12, XL-12, XR-13, XL-13 reaches parallel pole YU-01 via silver-colored lead, YD-01, YU-02, YD-02, YU-03, YD-03, XR-01, XL-01, XR-02, XL-02, XR-03, XL-03, the pressure drop that is produced is almost nil.In addition, because parallel pole also adopts silver-colored wire producing, therefore, the two-end-point of parallel pole just connects the part of resistance R 1, and its voltage is battery lead plate YU-11 no better than, YD-11, YU-12, YD-12, YU-13, YD-13, XR-11, XL-11, XR-12, XL-12, XR-13, the voltage that XL-13 supplied.And at the two ends of series connection electrode chains 120, then owing to resistance R 1 produces certain pressure drop.Produce the amplitude of pressure drop, look closely resistance R 1 and decide with the whole resistance (effective resistance) of the electrode chains 120 of connecting.That is the value of resistance R 1 can determine in advance, and design the resistance of resistance R 1 by the power consumption demand of reality.
To illustrate below how matrix type parallel electrode array of the present invention carries out the detecting of multi-point touch, Fig. 5～7th is that example describes with two touch points T1, the T2 of Fig. 4.The present invention sees through scanning in regular turn to X-axis, Y-axis parallel pole in each scan period, can obtain Y1, Y2 in regular turn, Y3, X1, X2, the X3 direction is because of the voltage that taken place of touching or the variation of electric current, and according to the point of the X-axis and the Y-axis of touch points, draws the position of touch points T1 accurately.
Fig. 5 is the scanning synoptic diagram that scans second axle for Fig. 4, the scanning of Y2 direction just, at this moment, parallel pole is supplied respectively+5V and ground connection YU-02/YD-02, other parallel pole is to suspension joint then, and conductive layer 110 is the state of not conducting in the part of Y1 direction and Y3 direction.So, be positioned at the touch points T1 in the 5th district, can be detected in the scanning of Y2 direction.
Fig. 6 is the scanning synoptic diagram that scans the 3rd axle for Fig. 4, the scanning of Y3 direction just, at this moment, parallel pole is supplied respectively+5V and ground connection YU-03/YD-03, other parallel pole is to suspension joint then, and conductive layer 110 is the state of not conducting in the part of Y1 direction and Y2 direction.So, be positioned at the touch points T2 in the 6th district, can be detected in the scanning of Y3 direction.
Fig. 7 is the scanning synoptic diagram that scans the 5th axle for Fig. 4, the scanning of X2 direction just, at this moment, parallel pole is supplied respectively+5V and ground connection XR-02/XL-02, other parallel pole is to suspension joint then, and conductive layer 110 is the state of not conducting in the part of X1 direction and X3 direction.So, being positioned at the touch points T1 in the 5th, 6 districts, T2 can be detected in the scanning of X2 direction.Wherein, because each block only can scan a point, therefore, the scanning result of Fig. 7 is the synthesis result for both.Therefore, the follow-up actual computation that also needs obtains real position.
After having scanned one-period, can obtain the touch points coordinate in the 5th district and the 6th district, and then judge that two touch points are arranged, and obtain the coordinate of two touch points by the scanning of Fig. 5～7.Because each parallel pole and connected series connection electrode chains are structurally identical or similar, as the embodiment of Fig. 4, it is nine parallel poles and the parallel electrode array that electrode chains constituted of connecting.So, when in the same scan period, supplying identical voltage, can obtain the result of identical touch position detecting.Wherein, in the power supply supply, the supply of operating voltage can be between 1.5～15V.
Matrix type parallel electrode array of the present invention can adopt the production method of different series connection electrode chains to reach the purpose that makes electric field homogenizing.The homogenising of Electric Field Distribution can make the precision of touch detection improve, and then promote user's user satisfaction.Therefore, each tame manufacturer is there's no one who doesn't or isn't at the precision improvement of analog contact panel and do effort.The precision of traditional analog Touch Screen can reach 1%, but, and can't carry out the detecting of multi-point touch.Use matrix type parallel electrode array of the present invention, can adopt single structure, design multiple different scan architecture, as the aforementioned MxN matrix person.
Because the influence of series electrical electrode structure is the precision nibble of touch detection, therefore, adopts different series electrical electrode structures, all can reach the purpose of multi-point touch detecting of the present invention.Below, will introduce several series electrical electrode structures.
Please refer to Fig. 8, it is contact panel first example of matrix type parallel electrode array of the present invention, and it has illustrated the series connection electrode chains 120 of Fig. 4 and the concrete framework of resistance R 1.The series connection electrode chains that each parallel pole connected is that corner electrode and the corner resistance that sees through two ends connects.In the present embodiment, each series connection electrode chains is to see through Z type electrode to make, and, in the part of Z type electrode, more be manufactured with discrete resistance chain near the contact region, inside of conductive layer 110.In addition, between parallel pole and the electrode chains of connecting and have insulating segment to isolate, in addition, between each parallel electrode array, also isolate with insulating segment.Detailed parallel electrode array 6 please refer to Fig. 9.
The parallel electrode array 6 of Fig. 9 is to be parallel pole YU-02 and 121 couplers in extension thereof.Because each parallel electrode array is structurally same or similar, therefore, only lifts a parallel electrode array at this and describes.On the both sides of structure, there is structure insulating segment 133 to allow parallel electrode array 6 and other parallel electrode array isolate, when scanning supply voltage to prevent to do, voltage is fed to adjacent parallel electrode array.Structure insulating segment 133 can allow the voltage of parallel electrode array 6, produces toward the electric field of the parallel pole YD-02 of an other symmetry, is formed with the regional electric field that separates.And in the bottom of parallel pole YU-02, one electrode insulation section 131 is then arranged, it allows the series connection electrode 123 of parallel pole YU-02 and the electrode chains of connecting form to isolate, and allows parallel pole YU-02 voltage can be seen through the parallel pole two ends but not central authorities are passed to the series connection electrode chains.The two ends of series connection electrode chains then respectively are connected with a corner electrode 122, and itself and parallel pole YU-02 form one at interval, and it is the part of conductive layer 110, can form resistance R 1.
The voltage that the Z type series connection electrode 123 of series connection electrode chains is transmitted behind the formed resistance in series chain of series connection electrode chains, has the generation of pressure drop, therefore, the voltage compensation of discrete resistance must be arranged, to allow the output voltage of series connection electrode chains can homogenising.Wherein, discrete resistance is by discontinuous insulation section 132 conductive layer 110 to be formed at interval to form.So the electric field that finally is created in the contact region, inside of conductive layer 110 will be comparatively even.
Electrode insulation section 131, discontinuous insulation section 132 can be made the space in the mode of etching or laser with structure insulating segment 133 on conductive layer 110, fill out with insulating material to form again.The pattern that it is concrete, person as shown in figure 10.Because each parallel electrode array is structurally same or similar, so electrode insulation section 131, discontinuous insulation section 132 and structure insulating segment 133 carry out balanced configuration according to 9 blocks of Figure 10.
On processing procedure, insulating segment is to be made on the conductive layer 110, again the conductive pane layer is made in conductive layer 110 afterwards.The conductive pane layer comprises the electrode that each are different, and person as shown in figure 11 according to the parallel pole YU-02 in the middle of the parallel electrode array of Fig. 9 and extension 121 thereof, the corner electrode 122 and the electrode chains 123 of connecting, produces the identical parallel electrode array of each block.By the electrode frame layer of Fig. 9 made, be formed at again on the conductive layer 110 of the insulating segment of having made Figure 10, can form the pattern of Fig. 8.
Fig. 8～11st is the explanation of first specific embodiment of series connection electrode of the present invention link structure, it has used series connection electrode chains and discontinuous insulation section to be formed on the conductive layer 110 constituting the discrete resistance section, and then is formed at the contact region, inside of conductive layer with allowing voltage homogenising that parallel pole transmitted.So, under the Control of Voltage of voltage control division that can be externally, produce the uniform electric field of different blocks according to the result of sequential control and voltage input, and then can detect the touch action of different blocks.
Next, please refer to Figure 12～14, it is second embodiment explanation of series connection electrode link structure of the present invention, and it is to make one first homogenizing electrode chains again in the contact region, inside of the close conductive layer 110 of discontinuous insulation section, it is formed at interval by a plurality of first equal polarizing electrode 124, as shown in figure 12 the person.Similarly, in the middle of each parallel electrode array, each makes one group of first homogenizing electrode chains, and it respectively comprises a plurality of first equal polarizing electrode 124.The first homogenizing electrode chains is the electric field that discrete resistance chain produced to be done homogenizing output, makes electric field energy that parallel electrode array produces on the border of the first homogenizing electrode chains, forms good homogenizing Electric Field Distribution, and its ripple effect significantly reduces.
Then, please refer to Figure 13, it is the enlarged drawing of parallel electrode array 7.Because each parallel electrode array is structurally same or similar, therefore, only lifts a parallel electrode array at this and describes.Parallel electrode array 7 is that with the difference of the parallel electrode array 6 of Fig. 9 it is made in the edge of discrete resistance chain, and is close to the contact region, inside of conductive layer 110 by the first equal polarizing electrode 124 formed first homogenizing electrode chains.Because the first homogenizing electrode chains is evenly distributed in the edge of discrete resistance chain, therefore, spread out of next voltage through compensation by discrete resistance chain, can on the first homogenizing electrode chains, conduct to fifty-fifty on the conductive layer 110, formation one is the electric field of homogenising more.That is, increase by the first homogenizing electrode chains after, can increase the linearity of the fringe field at conductive layer 110 edges, make the ripple effect lower.
Then, Figure 14 has then illustrated in the second embodiment of the invention of Figure 12, the figure of electrode frame layer.Can know discovery with Figure 11 comparison, the electrode frame layer of Figure 14 has increased the part of the first homogenizing electrode chains, and the rest is identical.In addition, the graphic designs of insulating segment can adopt the design of Figure 10 equally.
Next, please refer to Figure 15～17, it is the 3rd embodiment explanation of series connection electrode link structure of the present invention, and it is to make one second homogenizing electrode chains again in the contact region, inside of the close conductive layer 110 of the first homogenizing electrode chains, it is formed at interval by a plurality of second equal polarizing electrode 126, as shown in figure 15 the person.Similarly, in the middle of each parallel electrode array, each makes one group of second homogenizing electrode chains, and it respectively comprises a plurality of second equal polarizing electrode 126.The first homogenizing electrode chains is the electric field that discrete resistance chain produced to be done homogenizing output, makes electric field energy that parallel electrode array produces on the border of the first homogenizing electrode chains, forms good homogenizing Electric Field Distribution, and its ripple effect significantly reduces.
Then, please refer to Figure 16, it is the enlarged drawing of parallel electrode array 8.Because each parallel electrode array is structurally same or similar, therefore, only lifts a parallel electrode array at this and describes.Parallel electrode array 8 is with the difference of the parallel electrode array 7 of Figure 13, the first equal polarizing electrode 124 of Figure 13 is a line style, the first equal polarizing electrode 125 of Figure 16 then is T type (a cross bar portion and a straight-bar portion), and, Figure 16 includes the second homogenizing electrode chains of being made up of a plurality of second equal polarizing electrode 126 in addition, it is made in the edge of discrete resistance chain, and is close to the contact region, inside of conductive layer 110.Because the first homogenizing electrode chains is evenly distributed in the edge of discrete resistance chain, therefore, spread out of next voltage through compensation by discrete resistance chain, can on the first homogenizing electrode chains, conduct to fifty-fifty on the conductive layer 110, formation one is the electric field of homogenising more.That is, increase by the first homogenizing electrode chains after, can increase the linearity of the fringe field at conductive layer 110 edges, make the ripple effect lower.See through the configuration of the second homogenizing electrode chains again, can allow electric field homogeneity more.
Wherein, by observing among the figure, the second equal polarizing electrode 126 is to be line style, and the present invention adopts the straight-bar portion bottom and the second equal polarizing electrode 126 of the first equal polarizing electrode 125 to be arranged in parallel, so, can allow the output of the first equal polarizing electrode 125 identical, can allow its voltage be distributed in the contact region, inside of conductive layer 110 equably with the output reference point of the second equal polarizing electrode 126.Wherein, the best is the length that T type bottom (straight-bar portion) length of the first equal polarizing electrode 125 equals the second equal polarizing electrode 126, and the T type of the first equal polarizing electrode 125 bottom (straight-bar portion) edge and the formed clearance distance in edge of the second equal polarizing electrode 126 and the length ratio of the second equal polarizing electrode, the best is 2: 3, remaining ratio also can, as 1/5,1/4,1/3,1/2,2/5,2/7,3/5,3/7,4/5 ....The field uniformity the best that can actual test decides He Zhesuo to reach.
Then, Figure 17 has then illustrated in the third embodiment of the invention of Figure 15, the figure of electrode frame layer.Can know discovery with Figure 14 comparison, the electrode frame layer of Figure 17 has increased the part of the second homogenizing electrode chains, and the rest is identical.In addition, the graphic designs of insulating segment can adopt the design of Figure 10 equally.
First specific embodiment of Fig. 8～11, second specific embodiment of the 12nd～14 figure, and the 3rd specific embodiment of Figure 15～17 all apply to the design of discrete resistance chain.Can know discovery from Fig. 9, Figure 13 and Figure 16, the interior section of each Z type series connection electrode 123 all has a section an of discrete resistance; And the center of the vertical component of Z type series connection electrode, then to a section an of discrete resistance should be arranged.Because discrete resistance chain provides different resistance to export with the compensation as voltage as voltage to Z type electrode, so each Z type electrode will be consistent via the output voltage of discrete resistance section.Through the electric field homogenizing of the first homogenizing electrode chains and the second homogenizing electrode chains, fringe field distribution quite uniformly can be obtained again, the ripple effect of fringe field can be reduced effectively.
Wherein, the length of discrete resistance is that the making by discrete resistance section 132 realizes.Its length calculation can adopt multiple mode.Below, the present invention enumerates an example and does explanation, and the rest repeats no more.The length of discrete resistance can be according to Y=aX 2The formula of+b calculates its length.Computing method are described as follows:
1.X be Z type number of electrodes, for example, begin to start at total X1=1, X2=2, X3=3, X4=4, X5=5,5 Z type electrodes from the corner electrode for starting at by the corner electrode.
2.b be default value, it is obtained by experiment and statistics, the best is between 0.3～2.0mm.
3.a be to be calculated and got by Ymax, the size of Ymax can be obtained by contre electrode 429 length of Fig. 6 top.As for the length of contre electrode, then assess acquisition with the size of panel and the number of series connection electrode chains.The Ymax preferably respectively deducts 0.1mm about again for best for this electrode length.
4. by Ymax, b value and X value can obtain the worth parameter of a.
So, Y N-1Length, with Y N-1=a (n-1) 2+ b calculates, Y nLength, with Y n=a (n) 2+ b calculates it.And Y N-1With Y nMiddle Y N-0.5Length, can calculate it in two ways: I.X=(X N-1+ X n)/2, substitution formula again; II. with Y=(Y N-1+ Y n)/2.Actual effect, preferable with first formula.
Wherein, the optimum position of discrete resistance, be with the vertical section center of Z type electrode with and the center (centers at two vertical section centers) of interior section, the center that the center of the first equal polarizing electrode then corresponds to discrete resistance gets final product.Certainly, a little deviation that is produced on manufacturing perhaps, is carried out acentric configuration during design, but also is the present invention supplier, and it all can reach the effect that the present invention desires to reach.
In addition, on practice, the design that also can adopt the interior section of Z type electrode to distribute a plurality of discrete resistances.In other words, the present invention is between each electrode and electrode of series connection electrode chains, disposes a discrete resistance, and the interior section of each electrode, also configurable more than one the company is resistance.In addition, each noncontinuous electrode then configurable more than one first equal polarizing electrode, and between the first equal polarizing electrode, the then configurable more than one second equal polarizing electrode.That is, discrete resistance, the configuration of the quantity of the first equal polarizing electrode or the second equal polarizing electrode is a purpose with the problem that can reach the electric field homogenizing that institute of the present invention desire solves, accessible precision of its visual production equipment and cost are main consideration.
If adopt the electrode interior of each series connection electrode partly to design in the mode of a plurality of discrete resistances, just at the vertical section center of two Z type electrodes (if adopt other electrode framework, then be the electrode interior part between electrode and the electrode) dispose a plurality of discrete resistances, then be disposed at the length computation of discrete resistance therebetween, can adopt two kinds of above-mentioned account forms to obtain equally.For example, when adopting two discrete resistances to be disposed at the interior section of Z type electrode, its preferably is for to do equidistant configuration with the discrete resistance of both sides, as between Y N-1With Y nBetween the time, be respectively Y N-0.67, Y N-0.33And Y N-0.67=a (n-0.67) 2+ b is with Y N-0.33=a (n-0.33) 2+ b; Perhaps, Y N-0.67=(Y N-1* 2+Y n* 1)/3 with Y N-0.33=(Y N-1* 1+Y n* 2)/3.Wherein, also preferable with the former effect.
In addition, with the different discrete resistances that computing method obtained, also can be used for the present invention.As long as see through the of the present invention first equal polarizing electrode, perhaps, see through the collocation of the of the present invention first equal polarizing electrode and the second equal polarizing electrode, can form the good homogeneous voltage distribution.And Z type electrode only is an embodiment of the present invention, and the shape of other difference series connection electrode chains also can be used as embodiments of the invention.Because its principle is all identical, below repeats no more.
Wherein, the first homogenizing electrode chains, the second homogenizing electrode chains, corner electrode, series connection electrode chains, parallel pole, lead and battery lead plate or the like, good to take identical materials and method for making to form simultaneously.For example, adopt a kind of high temperature silver slurry of environmental-friendly lead-free, on screen painting program seal row transparency conducting layer.Be connected on the transparency conducting layer (conductive layer) through the silver of the high temperature more than 500 ℃ slurry Metal Melting, make conducting interface resistance value atomic little (can be considered nearly zero resistance) therebetween.It has the characteristic of high opposing variation of ambient temperature.In addition, silver-colored lead and conductive layer can obviously promote chemical resistance, product trust and permanance after high temperature crystallizationization.Perhaps, adopt other metal, as preferable metals of electric conductivity such as molybdenum/aluminium/molybdenum layer, chromium or other.
