Be described further below in conjunction with the method for concrete applied environment to the application's middle identification touch point:
Be illustrated in figure 2 as user's touch operation synoptic diagram, the touch-screen described in the embodiment of the present application can be the touch-screen of arbitrary induction information that can detect characteristics of human body's information or be caused by characteristics of human body's information.
In this specific embodiment electronic equipment A used be capacitive screens, detect at electronic equipment A and to have a plurality of touch points on the screen simultaneously, be provided with regularly pick-up unit of a screen electric capacity in electronic equipment A, described capacitance detecting device can remove to obtain the capacitance on the screen according to default time point.
When first user and second user touch simultaneously on the screen of electronic equipment in the present embodiment, electronic equipment A will detect three touch informations on the screen, corresponding three capacitance C1, C2 of difference, C3 in these three touch informations, therefore, the electric capacity range value S that in three touch informations, has just comprised three capacitance correspondences1, S2, S3
Determine to have three touch points at electronic equipment by described three electric capacity range values, be the M1 shown in Fig. 2, M2, three touch points of M3, for M1, M2, three touch points of M3 are corresponded to first user and second user, therefore M1, M2, three touch points of M3 need be sorted out.
In electronic equipment, prestore reference signal range value and a threshold value of first user and second user, at first obtain first user's reference signal range value S0An and threshold value L of first user's correspondence0, with each the electric capacity range value S that obtains1, S2, S3With S0Subtract each other, that is:

Wherein, L0For according to the user when the contacting electronic equipments screen, touch the change value range of the electric capacity range value of generation for a long time because of the user.
Embodiment two
In this application, also provide another kind of and determine that the operator of M touch point correspondence is the individual embodiment of N, specific as follows:
Electronic equipment obtains a preset range value, and this preset range value changes for the electric capacity range value that causes according to the sustained touch of user on electronic equipment screen.
After obtaining the preset range value, do merchant's quotient afterwards with being the merchant in twos between M the signal amplitude value, obtaining, quotient and preset range value are compared, the quotient in preset range is classified as a class.
Because each quotient is to be obtained by being the in twos merchant in M the signal amplitude value, just corresponding two signal amplitude values of each quotient so, and then after quotient is classified as a class, the signal amplitude value of quotient correspondence also correspondence be classified as a class.
After by above-mentioned method M signal amplitude value being sorted out, thereby the operator who determines M touch point correspondence is that N is individual.
Further specify technical scheme among the embodiment two below in conjunction with concrete applied environment.
At first electronic equipment gets access to first user and second user's M1, M2, the electric capacity range value S of three touch point correspondences of M31, S2, S3(as shown in Figure 2), with the S that gets access to1, S2, S3These three electric capacity range values are the merchant in twos, that is:
S1/S2＝K1 S2/S1＝K3 S3/S1＝K5
S1/S3＝K2 S2/S3＝K4 S3/S2＝K6
Wherein, K1, K2, K3, K4, K5, K6Be quotient, in order to make S1, S2, S3The electric capacity range value that is close in these three electric capacity range values is classified as a class, therefore, is provided with a preset range value in the embodiment of the present application, and this preset range value is the value range close to 1.
K wherein1, K3Value close to 1, S then1And S2Approach and equate.Therefore with K1, K2Corresponding electric capacity range value S1, S2Be classified as a class, and then with electric capacity range value S1, S2Corresponding touch point M1, M2 are classified as first user.
After touch point is sorted out, because the self-capacitance layer is made up of horizontal and longitudinal electrode array, therefore the self-capacitance layer detects respectively laterally and the longitudinal electrode array successively, according to changes in capacitance before and after touching, namely during the capacitance on gathering electronic equipment screen, can get access to X-amplitude value and Y-axis range value simultaneously, therefore, after getting access to M bar touch information and M bar touch information sorted out, obtain X-amplitude value and Y-axis range value in every touch information.
And then the self-capacitance layer calculates coordinate in X-axis and Y direction respectively according to X-amplitude value and Y-axis range value, is combined into the coordinate of touch point at last.
Further, after getting access to every touch information X-axis coordinate and Y-axis coordinate, according to every touch information X-axis coordinate in the described N touch information and Y-axis coordinate, determine the position of touch of each touch point on described screen in N the touch point of described N touch information correspondence.
In order to further specify the localization method to touch point, elaborate below in conjunction with concrete applied environment.
Be illustrated in figure 3 as a kind of touch point of the application location synoptic diagram, the specific implementation step is as follows:
At first, after M1, M2, three touch points of M3 are sorted out, the self-capacitance layer detects respectively laterally and the longitudinal electrode array successively, obtain the coordinate position on touch-screen of M1, M2, three touch point correspondences of M3 according to the electric capacity range value in each touch point, namely the M1 coordinate is that (X1, Y1), M2 coordinate are that (X2, Y2), M2 coordinate are (X3, Y3).
If single-point touches, then the projection in X-axis and Y direction all is unique, and the coordinate that is combined into also is unique.
M1, M2, three touch points of M3 are arranged on the touch-screen in the embodiment of the present application, because two touch points of M1, M2 not in same directions X or same Y-direction, have two projections respectively at X and Y-direction, therefore be combined into 4 coordinates.Obviously, it is real having only three coordinates, and another one is exactly that " the pseudo-touch point " that be commonly called as is touch point M4 (as shown in Figure 4).Therefore, the self-capacitance screen can't be realized real multiple point touching.
Further, for true coordinate and the realization multi-point touch that gets access to each touch point, be provided with a mutual capacitance layer in self-capacitance layer lower floor in the embodiment of the present application, wherein, the mutual capacitance layer also is to make transverse electrode and longitudinal electrode at glass surface with ITO, the place that two arrays of electrodes intersects will form electric capacity, also is the two poles of the earth that this two arrays of electrodes has constituted electric capacity respectively.
At four touch points of M1, M2, M3, M4 that are obtained from the capacitor layers, influenced the coupling between near two electrodes in touch point, thereby changed the electric capacity between these two electrodes.When detecting the mutual capacitance size, horizontal electrode sends pumping signal successively, and all electrodes receive signal simultaneously longitudinally, can obtain the capacitance size of all horizontal and vertical electrode joints like this, i.e. the capacitance size of the two dimensional surface of whole touch screen.
According to touch screen two-dimensional capacitance change data, can calculate the coordinate of each touch point in M1, M2, four touch points of M3, M4, therefore, even a plurality of touch points are arranged on the screen, also can calculate the true coordinate of each touch point.
Therefore, the mutual capacitance layer gets access to signal amplitude value and the rough coordinates position of touch point, be that the M1 coordinate is (X3, Y3) and pseudo-touch point coordinate M4 (X1, Y3) for (X1, Y1), M2 coordinate for (X2, Y2), M2 coordinate, in the mutual capacitance layer, be preset with error margin, touch point in this error margin scope is actual touch spots, be the difference of the range value between X-amplitude value and the Y-axis range value, judge according to this difference and error margin whether touch point is pseudo-touch point.
Therefore, according to the X-amplitude value of touch point M4 and the difference of the range value between the Y-axis range value, determine that touch point M4 is pseudo-touch point.
And therefore the mutual capacitance layer, can accurately locate the coordinate of M1, M2, three touch points of M3 by the mutual capacitance layer the induction sensitivity of touch point range value.
Therefore, by the self-capacitance layer a plurality of touch points on the electronic equipment screen are referred to corresponding operator, and by the mutual capacitance layer a plurality of touch points are accurately located on screen, arrived a plurality of operators when the enterprising line operate of screen, electronic equipment is distinguished user's operation by the self-capacitance layer on the screen and mutual capacitance layer.
