S101, the capacitance variation from appearance formed between the capacitance variation and the driving electrodes that determine the mutual tolerance formed between driving electrodes and induction electrode in the same sampling period and reference ground；
In the present embodiment, within the same sampling period, it is first determined the capacitance variation of the mutual tolerance formed between complete driving electrodes and induction electrode, then determine identical driving electrodes and the capacitance variation with reference to the appearance certainly formed between ground；Alternatively, within the same sampling period, it is first determined driving electrodes and the capacitance variation with reference to the appearance certainly formed between ground have determined the capacitance variation of the mutual tolerance formed between driving electrodes and induction electrode.Further, in order to save sampling time or power saving, it can determine between the capacitance variation of mutual tolerance between the driving electrodes and all induction electrodes of possible position of touch on touch-control array, and the driving electrodes and reference ground of possible touch-control within the same sampling period from the capacitance variation held.
In addition, it is necessary to which explanation, when due to there is touch-control generation, it is identical to report point induction electrode corresponding with true touch position by mistake, accordingly, it is difficult to distinguish wrong report point and true position of touch from appearance by induction electrode and with reference between ground.And for driving electrodes, wrong report point driving electrodes corresponding with true touch position are different, therefore, wrong report point and true position of touch can be distinguished from appearance by driving electrodes and with reference between ground, therefore, in the present embodiment, selects driving electrodes and determine wrong report point with reference to being formed between ground from the capacitance variation held, rather than by induction electrode and with reference to being formed between ground from holding
Capacitance variation determines wrong report point.
The present embodiment, when the capacitance variation of the mutual tolerance formed between the determining driving electrodes and induction electrode in step S101, can by the mutual tolerance that is formed between sample circuit turntable driving electrode and induction electrode with the determination mutual tolerance in current corresponding initial characteristic data, according to the mutual tolerance scanned in current corresponding initial characteristic data with mutual tolerance in no touch-control when corresponding reference characteristic data, so that it is determined that the capacitance variation of the mutual tolerance formed between driving electrodes and induction electrode, the structure of specific sample circuit can be found in the existing circuit of the prior art, details are not described herein.
In the present embodiment, in the specific implementation, driving signal can be provided to driving electrodes by driving circuit, and the inductive signal of induction electrode output is detected by sensor circuit, thus, passing through inductive signal described in sampling circuit samples, when due to there is finger touch, driving signal can be coupled to the inductive signal formed on induction electrode by mutual tolerance and be changed to reflect the variation of mutual tolerance, thus according to can the inductive signal of driving signal and acquisition determine the mutual tolerance formed between driving electrodes and induction electrode in current corresponding initial characteristic data.Specific driving circuit and sensor circuit can use the existing circuit of the prior art, and details are not described herein.
In the present embodiment, when determining the capacitance variation held certainly formed between the driving electrodes and reference ground in step S101, the driving electrodes can be specifically scanned by sample circuit to hold certainly with reference to what is formed between ground to determine described hold certainly in currently corresponding initial characteristic data, according to scanning from the corresponding reference characteristic data when current corresponding initial characteristic data is with from Rong Wu touch-control are held, the driving electrodes are determined and with reference to the capacitance variation held certainly formed between ground.
In the present embodiment, in the specific implementation, driving signal is provided to driving electrodes by driving circuit, and it detects and the output signal from the divider resistance for holding connection, the output signal of the divider resistance and the driving signal of driving electrodes are sampled by sample circuit, when due to there is finger touch, from the output signal that the variation of appearance can reflect divider resistance indirectly, come from appearance in current corresponding initial characteristic data to determine according to the driving signal of acquisition and the output signal of divider resistance.Can also be referring to other modes in the prior art about being sampled from the capacitance variation held, details are not described herein.
S102, it is determined according to the capacitance variation and the capacitance variation from appearance of determining mutual tolerance because dry
It disturbs and reports point caused by signal by mistake.
In the present embodiment, in step s 102, when reporting point by mistake caused by determining according to the capacitance variation of determining mutual tolerance and the capacitance variation from appearance because of interference signal, position of touch specifically can be determined according to the capacitance variation of determining mutual tolerance first, be determined in position of touch from the capacitance variation held because being reported by mistake a little caused by interference signal further according to described.
Specifically, in the present embodiment, according to it is described from the capacitance variation of appearance determine in position of touch the wrong report point caused by interference signal may include: due to the capacitance variation of the mutual tolerance is greater than or equal to set mutual capacitance change threshold described in be less than setting from the capacitance variation held and be judged to reporting by mistake a little caused by because of interference signal from the position of touch of capacitance change threshold, the capacitance variation of the mutual tolerance is more than or equal to and sets mutual capacitance change threshold and the capacitance variation from appearance is greater than or equal to setting and is determined as true position of touch from the position of touch of capacitance change threshold.
Above-mentioned mutual capacitance change threshold and it can determine that mutual capacitance change threshold and the size from capacitance change threshold can be adjusted according to actual needs according to there is the variation of capacitance before and after touch-control from capacitance change threshold.In the specific implementation, it is referred to above-described embodiment, the difference i.e. characteristic that capacitance variations are converted to said reference characteristic and initial characteristic data is changed, mutual capacitance change threshold is converted to corresponding characteristic change threshold from capacitance change threshold.Therefore, by the mutual tolerance, it is described be compared from the difference held between corresponding reference characteristic data and initial characteristic data with corresponding mutual capacitance change threshold, from capacitance change threshold, judgement be because of interference signal caused by wrong report put or true position of touch.
In addition, the capacitance of mutual tolerance can become smaller when having touch-control for mutual tolerance, and for having the capacitance of touch-control Shi Zirong that can become larger from for holding.But, for mutual tolerance or from for holding, since the transformation of capacitance can be converted into the variation of inductive signal or divider resistance output signal, the difference that sampling processing changes reference characteristic data and initial characteristic data into is carried out by adc circuit again, however, it is desirable to explanation, in other embodiments, also initial characteristic data and reference characteristic data difference can be set into, repeat no more in detail.Therefore in the present embodiment, in order to which unified judgment rule can be used to determine whether touching, no matter for mutual tolerance or from holding, reference characteristic data and initial characteristic data are set to as long as being all provided with
Difference, that is, characteristic variation (being equivalent to the variation of capacitor) be greater than corresponding threshold value then determine corresponding position of touch be true position of touch.

S201, the capacitance variation from appearance formed between the capacitance variation and the driving electrodes that determine the mutual tolerance formed between driving electrodes and induction electrode in Different sampling period respectively and reference ground.
Unlike the embodiments above is, in the present embodiment, in the capacitance variation for determining the mutual tolerance formed between driving electrodes and induction electrode in the previous sampling period, the same driving electrodes are determined in the latter sampling period and with reference to the capacitance variation from appearance formed between ground.
Alternatively, the capacitance variation from appearance formed between the driving electrodes and reference ground is determined in the previous sampling period, in the capacitance variation for determining the mutual tolerance formed between the same driving electrodes and induction electrode in the latter sampling period in an other embodiment.
Alternatively, in other embodiments, within the previous sampling period, determining the capacitance variation of the mutual tolerance formed between a driving electrodes and induction electrode, within the latter sampling period, another driving electrodes are determined and with reference to the capacitance variation from appearance formed between ground；Alternatively, in other embodiments, within the previous sampling period, determining another driving electrodes and determining the capacitance variation of the mutual tolerance formed between a driving electrodes and induction electrode within the latter sampling period from the capacitance variation held with reference to what is formed between ground.
S202, the first position of touch is determined according to the capacitance variation of determining mutual tolerance, determines the second position of touch from the capacitance variation held further according to described, is reported by mistake a little caused by being determined in the first position of touch according to second position of touch because of interference signal.
It is the position of touch for determining to report by the capacitance variation of mutual tolerance in above-described embodiment Fig. 1 embodiment in the present embodiment, then directly goes to determine wrong report point therein with from the capacitance variation held.And in the present embodiment, unlike the embodiments above is, the first position of touch, the second position of touch are determined according to the capacitance variation of mutual tolerance and from the capacitance variation held respectively, then it according to the intersection of second position of touch and the first position of touch, goes to determine the wrong report point in the first position of touch.Its detailed process
Can be with are as follows: the position of touch for including in first position of touch and second position of touch is determined as true position of touch, and only described first position of touch includes and the second position of touch touch location not to be covered is determined as reporting point by mistake.
In the present embodiment or above-mentioned Fig. 1 embodiment, for the mutual tolerance, when there is no finger touch, the capacitance of system direct-to-ground capacitance is smaller, so that interference signal such as the common mode interference signal can not be systematically formed into a loop between the earth, so that the original value characteristic of the correspondence mutual tolerance capacitance variation of detection does not change or varies less relative to reference characteristic data；And when there is finger touch, system direct-to-ground capacitance becomes larger from appearance, work mould interference signal can be flowed into the earth by human body at this time, so as to form interference loop transfer so the inductive signal of induction electrode changes with the variation of interference signal intensity, the capacitance for eventually leading to mutual tolerance also will receive interference and change.
In addition, in above-mentioned Fig. 1 or embodiment illustrated in fig. 2, it is contemplated that in different moments, the intensity of interference signal may quickly change with the time, can also can be changed so as to cause the wrong report point, simultaneously it is also possible to multiple wrong report points can occur in synchronization.
