In this first embodiment, before using contactor control device 100, the user can need select contactor control device 100 will operate in figure pattern or simulation model according to it.Then, control die set 111 is just sent control signal (not illustrating) to commutation circuit 112 according to user's selection result, so as to the control signal that causes commutation circuit 112 to be sent according to control die set 111, and contact panel 120 is coupled to digital control circuit 111-1 or analog control circuit 111-2, thereby make contactor control device 100 under figure pattern or simulation model, to operate.In other words, the user can select to see through digital control circuit 111-1 by commutation circuit 112 and judge the touched induction block of contact panel 120, or sees through analog control circuit 111-2 and find out touching coordinate (being touched position).
How to switch this two kinds of operator schemes for describing commutation circuit 112 in detail, please be simultaneously with reference to Fig. 1～Fig. 3, Fig. 3 is the synoptic diagram according to the commutation circuit 112 of first embodiment of the invention.Commutation circuit 112 comprises a plurality of multiplexers 311～318.Multiplexer 311～318 has signal end p1～p8, first pattern end a1～a8 and second pattern end b1～b8 respectively, and multiplexer 311～318 is controlled by the control signal that control die set 111 is sent.Wherein, signal end p1～p8 is coupled to the conductive electrode X1～X4 and the Y1～Y4 of contact panel 120 respectively.In this first embodiment, the multiplexer that is coupled to the conductive electrode that is positioned at contact panel 120 the same sides is regarded as same switching group, for example multiplexer 311 and 313 be all switch the G1 of group, multiplexer 312 and 314 be all switch the G2 of group, multiplexer 315 and 317 is all the switching G3 of group, and multiplexer 316 and 318 is all the switching G4 of group.
In this first embodiment, the switching group that is coupled to digital control circuit 111-1 corresponds to the different transparent conductive patterns of contact panel 120, for example is to switch the G1 of group and switch the G3 of group.In other words, first pattern end a1～a8 of multiplexer 311,313,315,317 is coupled to digital control circuit 111-1.In addition, the identical second pattern end b1～b8 part short circuit mutually of switching the multiplexer of group, for example be the second pattern end b1 and b3 short circuit, the second pattern end b2 and b4 short circuit, by that analogy to the short circuit mode of second pattern end b5～b8, and second pattern end b1～b8 is coupled to analog control circuit 111-2 again.
Hold above-mentionedly, the control signal that multiplexer 311～318 is sent according to control die set 111 decides a signal end p1～p8 to be couple to first pattern end a1～a8, or is couple to second pattern end b1～b8, so as to switching the operator scheme of contactor control device 100.When contactor control device 100 operates in figure pattern, digital control circuit 111-1 can carry out comprehensive scanning to contact panel 120 via conductive electrode X1, X3, Y1 and Y3, so as to when the user touches contact panel 120, sense the electric current that the induction block that touched produced and change or change in voltage.At this moment, digital control circuit 111-1 utilizes digital signal to define touched induction block, and different induction blocks is touched Shi Douhui and produces corresponding curtage variation.
For instance, when induction block R12 is touched by the user, overlapping transparent conductive patterns 222 and 211 can become conducting state, when digital control circuit 111-1 provided sweep signal to conductive electrode Y1 and Y3, digital control circuit 111-1 can detect voltage or electric current variation via conductive electrode X1.Similarly, if the user touches when responding to block R13 simultaneously, digital control circuit 111-1 can detect voltage or electric current variation via conductive electrode X3, and with the output matrix data, it corresponds to the transparent conductive patterns 222 and 221 that constitutes the induction block.Whereby, contactor control device 100 can be sensed a plurality of induction blocks simultaneously to reach function of multi-spot touch.
Transparent conductive patterns 221,222,211 and 212 overlapping parts among this first embodiment constitute four induction block R11, R12, R13 and R14 altogether, so contactor control device 100 at the most can four inductions of while sensing block.Certainly, if the quantity of induction block 140 increases (promptly increasing the quantity of transparent conductive patterns), then contactor control device 100 can carry out the more sensing of multiple spot.That is the transparent conductive patterns of above-mentioned 2 * 2 arrays is for illustrating, and practical design is not so limited, and can be the transparent conductive patterns of N * N array, and N is a positive integer.
On the other hand, when contactor control device 100 operates in simulation model, because identical second pattern end b1～b8 partly short circuit mutually earlier before being couple to analog control circuit 111-2 of switching the multiplexer of group, so contact panel 120 can be equivalent to traditional electric resistance touch-control panel, so analog control circuit 111-2 can detect the electric signal of contact panel 120, and calculated and orient the touching coordinate, and output coordinate data.Yet the technology of these location is not the emphasis that the present invention ponders, and these technology belong to field of the present invention again and have and know that usually the knowledgeable knows well, so at this and no longer given unnecessary details.
Based on the content that above-mentioned first embodiment is disclosed, the driving method of putting in order out a kind of contactor control device 100 of below will converging has for field of the present invention to know that usually the knowledgeable considers and examines.Fig. 4 illustrates the method flow diagram into the operator scheme of the switching contactor control device 110 of first embodiment of the invention.Please refer to Fig. 4, the method for the operator scheme of the switching contactor control device 100 of present embodiment comprises the following steps: at first, and control signal (step S410) is provided.Then, contactor control device 110 to be operated in figure pattern or simulation model (step S420) according to control signal to judge.When control signal corresponds to figure pattern, scan and detect induction block (step S430) touched in the contact panel; When control signal corresponds to simulation model, detect and calculate the touched position (step S450) in this contact panel.
In addition, after step S430, more can corresponding output matrix data (step S440).And after step S450, more can corresponding output touching coordinate (step S460).
From the above, the user can look its operator scheme that need decide contactor control device 100, if need carry out multi-point touch, then can see through commutation circuit 112 contactor control device 100 is switched to figure pattern, if carry out the location of high-res, then can switch to simulation model to contactor control device 100.
Second embodiment
In addition, the present invention more provides another commutation circuit to carry out different switching modes.Fig. 5 is the synoptic diagram according to the commutation circuit 112 of second embodiment of the invention.Please be simultaneously with reference to Fig. 1 and Fig. 5, commutation circuit 112 comprises to be switched the G1～G4 of group and selects circuit 513.Switch the G1～G4 of group and comprise a plurality of multiplexers 311～318, and select circuit 513 to comprise multiplexer 513-1～513-4.
Similarly, the same signal end that switches the multiplexer of group can be coupled to the conductive electrode that is positioned at contact panel 120 the same sides, and the switching group that corresponds to contact panel 120 different transparent conductive patterns is coupled to digital control circuit 111-1, for example is to switch the G1 of group and switch the G3 of group.In other words, the first pattern end a1, a3, a5 and the a7 of multiplexer 311,313,315,317 are coupled to digital control circuit 111-1.In addition, second pattern end b1～b8 of multiplexer 311～318 sees through multiplexer 513-1～513-4 and is couple to analog control circuit 111-2.
More specifically, the second pattern end of the multiplexer of same group can be couple to the first data end of multiplexer 513-1～513-4 respectively, for example the second pattern end b1, b3 see through multiplexer 513-1 and are coupled to analog control circuit 111-2, the second pattern end b2, b4 and see through that multiplexer 513-2 is coupled to analog control circuit 111-2, the second pattern end b5, b7 see through multiplexer 513-3 and be coupled to analog control circuit 111-2, and the second pattern end b6, b8 see through multiplexer 513-4 and be coupled to analog control circuit 111-2.Wherein, multiplexer 513-1～513-4 is controlled by the matrix data that digital control circuit 111-1 is exported.
Further, contactor control device 100 can operate in figure pattern earlier, this moment, the signal end p1～p8 of multiplexer 311～318 was coupled to first pattern end a1～a8, allow digital control circuit 111-1 scan contact panel 120 earlier, to find touched induction block, and the output matrix data (s1, s2), it is to correspond to touched induction block.As previously mentioned, two transparent conductive patterns overlapping block be the induction block, and the matrix data (s1 s2) can be in order to store the relative position in contact panel 120 of these two transparent conductive patterns.Then, digital control circuit 111-1 can send control signal (not illustrating) to commutation circuit 112, so that contactor control device 100 is switched to simulation model, just allows commutation circuit 112 that signal end p1～p8 is switched to and is coupled to second pattern end b1～b8.
Then, more (s1 s2) selects to desire to be coupled to the conductive electrode of analog control circuit 111-2 according to the matrix data to select circuit 513.Thus, analog control circuit 111-2 just can find the touching coordinate, and will touch coordinate respectively and be stored in the matrix data (s1 is s2) in the pairing working area.
For instance, when the user touched the induction block R12 of contact panel 120, (s1, s2), (s1 s2) promptly corresponded to transparent conductive patterns 211 and 222 respectively to the matrix data via meeting output matrix data after the digital control circuit 111-1 scanning detection.Then, commutation circuit 112 is coupled to analog control circuit 111-2 according to the control signal that digital control circuit 111-1 is exported with contact panel 120 again.
Wherein, multiplexer 513-1 and 513-2 are according to matrix data (s1, s2) the matrix element s1 in selects the conductive electrode X1 and the X2 at transparent conductive patterns 211 two ends to be coupled to analog control circuit 111-2, just the second pattern end b1 and b2 is coupled to analog control circuit 111-2.Similarly, multiplexer 513-3 and 513-4 are according to matrix data (s1, s2) the matrix element s2 in selects the second pattern end b7 and b8 to be coupled to analog control circuit 111-2, and just conductive electrode Y3 and the Y4 with transparent conductive patterns 222 two ends is coupled to analog control circuit 111-2.
At last, analog control circuit 111-2 just can scan and calculate the touching coordinate at induction block R12, and with this coordinate data storage in matrix data (s1, s2) pairing working area.Similarly, at present embodiment, detect the incident of touching whenever digital control circuit 111-1, just can switch to analog control circuit 111-2, to do the action of location at these touch points, thus, just can reach multi-point touch function with high-res at touched induction block.
Based on the content that above-mentioned second embodiment is disclosed, the driving method of putting in order out another kind of contactor control device 100 of below will converging has for field of the present invention to know that usually the knowledgeable considers and examines.Fig. 6 illustrates the method flow diagram into the operator scheme of the switching contactor control device 110 of second embodiment of the invention.Please refer to Fig. 6, the method for the operator scheme of the switching contactor control device 100 of present embodiment comprises the following steps: at first, and scanning numbering X and Y (step S605) are provided, and sets X=1, Y=1.In the present embodiment, contact panel 120 has m horizontal transparent conductive patterns and n vertical transparent conductive patterns, wherein horizontal transparent conductive patterns is the transparent conductive patterns of extending along first direction D1, and vertical transparent conductive patterns is the transparent conductive patterns of extending along second direction, and first direction for example is vertical with second direction, but not as limit.
Then provide electric signal (step S610) by X horizontal transparent conductive patterns.Wherein, electric signal for example is that change in voltage or electric current change, but not as limit.In addition, operate in figure pattern, can export control signal earlier so that contactor control device is switched to figure pattern for guaranteeing contactor control device.When control signal corresponds to figure pattern, detect electric signal (step S615) by Y vertical transparent conductive patterns.Afterwards, judged whether to detect electric signal (step S620), if detect electric signal, i.e. representative has touch event to take place.
When detecting electric signal, detect and calculate touching coordinate (step S625), it should be noted that this is the operation of simulation model, so need to export control signal earlier so that contactor control device is switched to simulation model.Then, the touching coordinate is stored the working area (step S630) that the matrix data is corresponded to, this matrix data promptly corresponds to X horizontal transparent conductive patterns and Y transparent conductive patterns.
Otherwise, if when not detecting electric signal, then skips steps S625 and step S630, directly carry out next step to judge whether Y equals n (step S635), this promptly judges whether to have scanned whether been scanned of all vertical transparent conductive patterns, if Y is not equal to n, then sets Y=Y+1 (step S640), carrying out the scanning of next vertical transparent conductive patterns, and then get back to step S615.If Y equals n, promptly represent all been scanned of all vertical transparent conductive patterns, and judge then whether X equals m (step S645), similarly, this judges whether that promptly all horizontal transparent conductive patterns all provide electric signal, if X is not equal to m, then sets X=X+1 (step S650), so that next horizontal transparent conductive patterns provides electric signal, and then get back to step S610.
If X equals m, i.e. expression is fully once scanned at contact panel 120, and output matrix data (step S655), and this matrix data has promptly comprised aforesaid matrix data.In other words, after contact panel 120 was scanned once, each touched position can be detected, so contactor control device 110 just can carry out multi-point touch.

Please refer to Fig. 8 B, show the analog driving method process flow diagram of third embodiment of the invention.Present embodiment system only is set in the operator scheme of analog driving method, so step S814 here is omitted.Analog driving method step comprises: chip for driving is imported different voltages respectively by the two ends of first conductive pattern 711,712,713 in regular turn by first electrode X10～X31.The voltage of X10, X20, X30 input 0V (volt) for example, the voltage of X11, X21, X31 input 5V (volt) makes the voltage difference (step S816) of a 5V of formation between the two end electrodes of each first conductive pattern.Then, detect by the 5V voltage difference by the second electrode Y10～Y31 at second conductive pattern, 721～723 two ends and calculate the one or more sensing voltage signals (sensing voltagesignal) of one or more voltage division signal of gained as correspondence.At this moment, can directly above-mentioned sensing voltage signal directly be back to the coordinate (step S824) of chip for driving to define one or more first directions, also can optionally open one and get rid of the function that flase drop is surveyed, this can be described follow-up.
Then, chip for driving is imported different voltages respectively to the two ends of second conductive pattern 721,722,723 in regular turn by second electrode Y10～Y31.The voltage of Y10, Y20, Y30 input 0V for example, the voltage of Y11, Y21, Y31 input 5V makes the voltage difference (step S826) that forms a 5V between the two end electrodes of each second conductive pattern.Form the voltage difference of a 5V between the two end electrodes of second conductive pattern.Then, detect by the 5V voltage difference by the first electrode X10～X31 at first conductive pattern, 711～713 two ends and calculate the one or more sensing voltage signals of one or more voltage division signal of gained as correspondence.At this moment, can directly above-mentioned sensing voltage signal directly be back to the coordinate (step S834) of chip for driving to define one or more second directions, also can optionally open one and get rid of the function that flase drop is surveyed, this also can be described follow-up.
At last, obtain an accurate coordinate points position after the coordinate of the coordinate of a first direction and a second direction occured simultaneously, or obtain a plurality of accurate coordinate points positions (step S836) behind the coordinate of the coordinate of a plurality of first directions and a plurality of second directions common factor, and be output as one or more coordinates (step S838) that touch.Like this, can reach single-point or function of multi-spot touch.
Please return with reference to figure 7, when induction block I, VII, when IX is touched simultaneously (the label star is arranged), can will be arranged in conductive pattern 721,723 mutual conduction of the conductive pattern 711,713 of transparency carrier and following transparency carrier and form a conduction path shown in graphic dotted line.Might derive a problem like this, the electrode Y10 at second conductive pattern, 721 two ends or Y11 might detect the sweep signal of input first conductive pattern 713, for example be the voltage of 5V, thereby be driven chip and think that induction block III (the label cross is arranged) has and touched by mistake.Make that last output matrix data is to comprise I, III, VII, four inductions of IX block.In fact this do not touched but really have the induction block III of OPADD information to be surveyed by flase drop significantly on the contrary.
In view of the above-mentioned problem that may derive, between aforesaid step S816 and the step S824, also can optionally insert one and get rid of the function that flase drop is surveyed, for example described flow process of step S818～S822.Be summarized as follows: after second electrode detection arrives one or more sensing voltage signals, with each sensing voltage signal with one first predetermined numerical range compare (step S818), judge whether the sensing voltage signal falls in first numerical range (step S820), if set up the coordinate of the corresponding first direction of then output.If be false, then with second electrode detection to one or more sensing voltage signals be considered as the flase drop measured value and do not exported.
Similarly, between step S826 and the step S834, also can optionally insert one and get rid of the function that flase drop is surveyed.After first electrode detection arrives one or more sensing voltage signals, with each sensing voltage signal with a predetermined second value scope compare (step S828), judge whether the sensing voltage signal falls in the second value scope (step S830), if set up the coordinate of the corresponding second direction of then output.If be false, then with first electrode detection to one or more sensing voltage signals be considered as the flase drop measured value and do not exported.
Please also refer to Fig. 7 and Fig. 8 B, step S818～S822 can further followingly illustrate.At first define the always total n of first conductive pattern that extends along first direction (for example D1 direction among Fig. 7)
tIndividual, n
t=1,2,3...n-1, n, n+1......, n is a positive integer, the always total n of first conductive pattern among Fig. 7
t=3, from bottom to top be defined as n=1,2,3 (also can from top to bottom define).Second conductive pattern that extends along second direction (for example D2 direction among Fig. 7) always has m
tIndividual, m
t=1,2,3...m-1, m, m+1..., m is a positive integer, the always total m of second conductive pattern among Fig. 7
t=3, the right side is defined as m=1,2,3 (also can by right and left side definition) by a left side.
The driving method that judges whether wrong detection comprises: one first voltage V1 is provided first electrode to n bar first conductive pattern one end, for example provides V1=5V (volt) to give first electrode (X31) of the 1st (n=1) first conductive pattern 713 1 ends.One second voltage V2 then is provided first electrode to the identical n bar first conductive pattern other end, for example provides V2=0V (volt) to give first electrode (X30) of same the 1st (n=1) first conductive pattern 713 other ends.The voltage difference that therefore two ends of first conductive pattern 713 can exist 5V (volt) is detected by second conductive pattern 721～723 again.Suppose the m bar second conductive pattern two ends second electrode (Y20 and Y21) one of them detects sensing voltage signal Vs at least, then begin comparison sensing voltage signal Vs whether fall into first numerical range of setting [(V1-V2)/m
t] * (m-1)＜Vs＜[(V1-V2)/m
t] in the * m.If sensing voltage signal Vs falls in first numerical range, then export the coordinate of this first direction, if this sensing voltage signal Vs does not fall in this first numerical range, then sensing voltage signal Vs is considered as a flase drop measured value and is got rid of.
For example, touched and touched simultaneously the duration when induction block I, VII, IX and enough can be scanned complete contact panel by the sweep signal of the bilateral input of contact panel.Article 1, first electrode (X11) of first electrode (X31) of (n=1) first conductive pattern 713 1 ends and the 3rd (n=3) first conductive pattern 711 1 ends has for example 5V (volt) voltage input, first electrode (X10) with for example (X30) have 0V (volt) voltage and import.This moment the 1st (m=1) second conductive pattern 721 can detect two respectively from the 5V (volt) of first electrode (X11 and the X31) input of first conductive pattern 711 and 713 1 ends or less than and near the voltage of 5V, correspond to respectively and respond to block I and III.It is because the relation of conduction path shown in dotted lines in Figure 7 that induction block III can be surveyed by flase drop.
Can be set in [(5-0)/3] * (1-1) and [(5-0)/3] * 1 between by the 1st (m=1) second conductive pattern 721 detected first numerical ranges this moment, that is between 0～1.67.Mode can be set between [(5-0)/3] * (2-1) and [(5-0)/3] * 2 by the 2nd (m=2) second conductive pattern 722 detected first numerical ranges according to this, that is between 1.67～3.33.Can be set between [(5-0)/3] * (3-1) and [(5-0)/3] * 3 by the 3rd (m=3) second conductive pattern 723 detected first numerical ranges, that is between 3.33～5.
After first numerical range defines and finishes, promptly can inspect judgement.Article 1, (m=1) second conductive pattern 721 is by conduction path shown in dotted lines in Figure 7 in response to the 1st (n=1) first conductive pattern 713, and then detects a sensing voltage signal Vs=5V (volt).Significantly, Vs does not fall between first numerical range 0～1.67, gives and gets rid of so Vs is considered as a flase drop measured value.Therefore, induction block III promptly can not be mistaken as and touched.Otherwise, article 1, detected sensing voltage signal Vs is near 0V or than 1.67V little (actual value needs to get according to dividing potential drop calculating) to (m=1) second conductive pattern 721 in response to the 3rd (n=3) first conductive pattern 711, therefore be to fall between first numerical range 0V～1.67V, be considered as right value and be output as the first direction coordinate.
In like manner, step S828～S832 can adopt above-mentioned mode, with first electrode detection to sensing voltage signal and second value scope compare, to judge whether the being flase drop measured value.The type of drive flow process is exemplified below: second electrode of a tertiary voltage V3 to m bar second conductive pattern one end (for example Y11, Y21, Y31 import 5V) at first is provided, second electrode of one the 4th voltage V4 to the same m bar second conductive pattern other end (for example Y10, Y20, Y30 import 0V) then is provided, then by first electrode at the n bar first conductive pattern two ends (for example X10～X31) at least wherein one detect another sensing voltage signal Vf.First electrode this moment (X10 and X11) can detect near or equal the voltage (sensing voltage signal Vf) of 5V, and first electrode (X30 and X31) also can detect 5V voltage (sensing voltage signal Vf).With the comparison of above-mentioned two sensing voltage signal Vf and second value scope, judge and whether fall into [(V3-V4)/n
t] * (n-1)＜Vf＜[(V3-V4)/n
t] in the * n scope.If sensing voltage signal Vf falls in the second value scope, then export the coordinate of this second direction, if this sensing voltage signal Vf does not fall in this second value scope, then sensing voltage signal Vf is considered as a flase drop measured value and is got rid of.
Can be set in 0～1.67 between by the 1st (n=1) first conductive pattern 713 detected second value scopes this moment, can be set between 1.67～3.33 by the 2nd (n=2) first conductive pattern 712 detected second value scopes, can be set between 3.33～5 by the 3rd (n=3) first conductive pattern 713 detected second value scopes.
After the second value scope definition is finished, inspect judgement.Article 1, (n=1) first conductive pattern 713 is the conduction path shown in dotted line in Fig. 7 reverse in response to the 1st (m=1) second conductive pattern 721, and then detects a sensing voltage signal Vf=5V (volt).Significantly, Vf does not fall between the second value scope 0～1.67, gives and gets rid of so Vf is considered as a flase drop measured value.Therefore, induction block III promptly can not be mistaken as and touched.Otherwise, article 3, detected sensing voltage signal Vf is near 5V or than 3.33V big (actual value needs to get according to dividing potential drop calculating) to (n=3) first conductive pattern 711 in response to the 1st (m=1) second conductive pattern 721, therefore be to fall between second value scope 3.33V～5.0V, be considered as right value and be output as the second direction coordinate.
By step S818～S822 and step S828～S832, can screen wrong sensing voltage signal, make correct single-point or the multiple spot of chip for driving output touch coordinate position.Moreover the step S450 that step S814～S836 can be considered as among the figure four further illustrates.
Step S816～S838 is set in simulation model to detect, as above-mentioned be to adopt respectively mode to detect for example to each conductive pattern input scan signal.Another kind of simulation model detection mode also can will be positioned at the electric pole short circuit of the same side of contact panel in the driving process.For example, please refer to Fig. 7, in the driving process of scanning and detection, can will be positioned at the electric pole short circuit at the first or second conductive pattern two ends by chip for driving.Clearer and more definite, (X10～X31) be positioned at the mutual short circuit of first electrode (X10, X20, X30) of the same end of first conductive pattern (711～713) in all first electrodes to receive one first voltage (for example 0V volt) simultaneously.The mutual short circuit of all the other first electrodes (X11, X21, X31) that is positioned at first conductive pattern (711～713) other end is to receive one second voltage (for example 5V volt) simultaneously, making wins forms one first voltage difference between the conductive pattern two ends, that is 5 volts voltage difference is as sweep signal.Simultaneously, (Y10～Y31) is positioned at second electrode (Y10, Y20, the Y30) short circuit mutually of the same end of second conductive pattern (721～723), is positioned at all the other second electrodes (Y11, Y21, Y31) short circuit mutually of the second conductive pattern other end in all second electrodes.At this moment, second electrode can be in order to detect at least one voltage division signal of calculating gained by first voltage difference, and be back to chip for driving to define the coordinate of first direction, for example hypothesis detects 0.5 volt, the coordinate of first direction contact panel 701 left sides relatively partially then, if detect 4 volts, the coordinate of first direction contact panel 701 right sides relatively partially then.Next, use same type of drive, be positioned at second electrode (Y11, Y21, the Y31) short circuit mutually of second conductive pattern (721～723) upper end, to receive a tertiary voltage (for example 5V volt) simultaneously, all the other second electrodes (Y10, Y20, Y30) short circuit mutually make to form one second voltage difference (5V volt) between the second conductive pattern two ends as sweep signal to receive one the 4th voltage (for example 0V volt) simultaneously.(short circuit mutually of X10～X30) is positioned at the first electrode (X11～X31) also short circuit mutually of the first conductive pattern right-hand member to be positioned at first electrode of the first conductive pattern left end this moment.Detect as detecting electrode with first electrode, can calculate a voltage division signal, and be back to chip for driving to define the coordinate of second direction by second voltage difference.At last, can obtain one in conjunction with first direction coordinate and second direction coordinate and touch coordinate position accurately.
Please also refer to Fig. 7, Fig. 8 A, Fig. 8 B, present embodiment also can be contacted step S802～S838, and carries out carrying out after the first Digital Detecting pattern of analog detection.For example, when chip for driving goes out the induction block I and the IX of being touched with the mode-definition of Digital Detecting earlier, for example step S802～S806 then just judges to enter analog detecting pattern (step S810) and coherent in step S816～S838 by illustrated B flow process.With different being in before entering step S816～S838 of aforementioned analog detection pattern, a action (step S814) that meeting is many by driving governor change detection pattern.In other words, after defining the induction block I and IX of being touched, first conductive pattern 711 and second conductive pattern 721 of corresponding induction block I can switch to analog detecting pattern, and first conductive pattern 713 and second conductive pattern 723 of corresponding induction block IX also can switch to analog detecting pattern.So, just can be simultaneously in conjunction with the advantage of Digital Detecting and two kinds of patterns of analog detection, can reach multi-point touch again energy measure the dual purpose of accurate position.Type of drive can refer step S802～S838, and something in common is no longer given unnecessary details.
