Embodiment one
When user carries out touch operation to electronic equipment, the first time of user is contacted the signal amplitude value that generates on screen as reference signal range value by electronic equipment, and is stored by this reference signal range value.
First the reference signal range value of a threshold value and each operator prestored in electronic equipment is obtained in the application, the signal amplitude value getting each touch point in M touch point and the reference signal range value prestored are subtracted each other, thus obtains M difference between signal amplitude value and reference signal range value.
The described threshold value prestored is change according to the characteristic information of human body the value range determined.
Further, each difference in M difference and the threshold value prestored are compared, if have multiple difference in threshold range, so touch information corresponding for this multiple difference is classified as a class, the corresponding signal amplitude value of each difference in this multiple difference, the corresponding touch point of each signal amplitude value, therefore, after signal amplitude value being sorted out, and then multiple touch point is classified as a class.
M touch point to be sorted out respectively in the embodiment of the present application, and then M touch point is defined as N class touch point, therefore a described M touch point is defined as N number of operator.
Below in conjunction with embody rule environment to identifying in the application that the method for touch point is described further:
Be illustrated in figure 2 user's touch operation schematic diagram, the touch-screen described in the embodiment of the present application can be the touch-screen of arbitrary induction information that characteristics of human body's information can be detected or caused by characteristics of human body's information.
In this specific embodiment, electronic equipment A is used is capacitive screens, detect that screen exists multiple touch point simultaneously at electronic equipment A, in electronic equipment A, be provided with a screen electric capacity timing detection device, described capacitance detecting device can go according to the time point preset to obtain the capacitance on screen.
When first user and the second user touch on the screen of the electronic device simultaneously in the present embodiment, electronic equipment A will detect three touch informations on screen, difference corresponding three capacitances C1, C2, C3 in these three touch informations, therefore, in three touch informations, just contain the electric capacity range value S that three capacitances are corresponding1, S2, S3.
Determine to there are three touch points at electronic equipment by described three electric capacity range values, namely M1, M2, M3 shown in Fig. 2 tri-touch points, in order to M1, M2, M3 tri-touch points are corresponded to first user and the second user, therefore need M1, M2, M3 tri-touch points to sort out.
Prestore reference signal range value and a threshold value of first user and the second user in the electronic device, first obtain the reference signal range value S of first user0and the threshold value L that first user is corresponding0, by each electric capacity range value S obtained1, S2, S3with S0subtract each other, that is:
S1-S0＝J1
S2-S0＝J2
S3-S0＝J3
Thus obtain difference J corresponding to three touch informations1, J2, J3, by three difference J1, J2, J3with threshold value L0compare, wherein J1, J2at threshold value L0in the scope of setting, then by J1, J2corresponding touch information is classified as a class, J in the present embodiment1, J2corresponding touch point is M1 and M2, and therefore M1 touch point and M2 touch-control are classified as first user by electronic equipment.
Wherein, L0for according to user when contacting electronic equipments screen, touch the change value range of the electric capacity range value of generation for a long time because of user.
Embodiment two
In this application, the operator that M touch point is corresponding is N number of embodiment also to provide another kind to determine, specific as follows:
Electronic equipment obtains a preset range value, and this preset range value is that the electric capacity range value caused according to the sustained touch of user on electronic equipment screen changes.
After acquisition preset range value, be business between two by between M signal amplitude value, obtain the quotient after being business, quotient and preset range value are compared, the quotient in preset range is classified as a class.
Because each quotient is business by carrying out between two in M signal amplitude value to obtain, so each quotient just corresponding two signal amplitude values, and then after quotient is carried out being classified as a class, signal amplitude value corresponding to quotient is also corresponding is classified as a class.
After M signal amplitude value being sorted out by above-mentioned method, thus determine that operator that M touch point is corresponding is for N number of.
The technical scheme in embodiment two is further illustrated below in conjunction with embody rule environment.
First electronic equipment gets electric capacity range value S corresponding to M1, M2, M3 tri-touch points of first user and the second user1, S2, S3(as shown in Figure 2) S, will got1, S2, S3these three electric capacity range values are business between two, that is:
S1/S2＝K1S2/S1＝K3S3/S1＝K5
S1/S3＝K2S2/S3＝K4S3/S2＝K6
Wherein, K1, K2, K3, K4, K5, K6for quotient, in order to make S1, S2, S3the electric capacity range value be 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.
Wherein K1, K3value close to 1, then S1and S2close to equal.Therefore by K1, K2corresponding electric capacity range value S1, S2be classified as a class, and then by electric capacity range value S1, S2corresponding touch point M1, M2 are classified as first user.
After touch point is sorted out, because self-capacitance layer is made up of transverse direction and longitudinal electrode array, therefore self-capacitance layer detects laterally and longitudinal electrode array successively respectively, according to the change touching front and back electric capacity, namely, when gathering the capacitance on electronic equipment screen, X-amplitude value and Y-axis range value can be got, therefore simultaneously, after getting M bar touch information and sorted out by M bar touch information, obtain the X-amplitude value in every bar touch information and Y-axis range value.
And then self-capacitance layer calculates coordinate in X-axis and Y direction respectively according to X-amplitude value and Y-axis range value, is finally combined into the coordinate of touch point.
Further, after getting every bar touch information X-axis coordinate and Y-axis coordinate, according to bar touch information X-axis coordinate every in described N number of touch information and Y-axis coordinate, determine each touch point position of touch on the screen in N number of touch point that described N number of touch information is corresponding.
In order to further illustrate the localization method to touch point, elaborate below in conjunction with embody rule environment.
Be illustrated in figure 3 a kind of touch point location of the application schematic diagram, specific implementation step is as follows:
First, after M1, M2, M3 tri-touch points are sorted out, self-capacitance layer detects laterally and longitudinal electrode array successively respectively, obtain coordinate position on the touchscreen corresponding to M1, M2, M3 tri-touch points according to the electric capacity range value in each touch point, namely M1 coordinate is (X1, Y1), M2 coordinate is (X2, Y2), M2 coordinate is (X3, Y3).
If single-point touches, be then all unique in the projection of X-axis and Y direction, the coordinate be combined into also is unique.
In the embodiment of the present application touch-screen there are M1, M2, M3 tri-touch points, because M1, M2 two touch points are not in same X-direction or same Y-direction, have two projections respectively at X and Y-direction, be therefore combined into 4 coordinates.Obviously, only have three coordinates to be real, another one is exactly that " the pseudo-touch point " that be commonly called as is touch point M4 (as shown in Figure 4).Therefore, self-capacitance screen cannot realize real multiple point touching.
Further, in order to get the true coordinate of each touch point and realize multi-point touch, in the embodiment of the present application self-capacitance layer lower floor is provided with a mutual capacitance layer, wherein, mutual capacitance layer is also make transverse electrode and longitudinal electrode at glass surface ITO, the place that two arrays of electrodes intersects will form electric capacity, and also namely this two arrays of electrodes constitutes the two poles of the earth of electric capacity respectively.
At M1, M2, M3, M4 of being obtained from capacitor layers tetra-touch points, have impact on the coupling between two electrodes near touch point, thus change the electric capacity between these two electrodes.When detecting mutual capacitance size, horizontal electrode sends pumping signal successively, and longitudinal all electrodes Received signal strength simultaneously, can obtain the capacitance size of all horizontal and vertical electrodes intersect points, i.e. the capacitance size of the two dimensional surface of whole touch-screen like this.
According to touch screen two-dimensional capacitance change data, the coordinate of each touch point in M1, M2, M3, M4 tetra-touch points can be calculated, therefore, even if screen there is multiple touch point, also can calculate the true coordinate of each touch point.
Therefore, mutual capacitance layer gets signal amplitude value and the rough coordinates position of touch point, namely M1 coordinate is (X1, Y1), M2 coordinate is (X2, Y2), M2 coordinate is (X3, Y3) and pseudo-touch point coordinate M4 (X1, Y3), error margin is preset with in mutual capacitance layer, touch point in this error tolerance range is actual touch spots, the difference of the range value namely between X-amplitude value and Y-axis range value, judges touch point whether as pseudo-touch point according to this difference and error margin.
Therefore, according to the difference of the range value between the X-amplitude value of touch point M4 and Y-axis range value, determine that touch point M4 is pseudo-touch point.
Further, the induction of mutual capacitance layer to touch point range value is sensitive, therefore, the coordinate of M1, M2, M3 tri-touch points accurately can be located by mutual capacitance layer.
Therefore, by self-capacitance layer, the multiple touch points on electronic equipment screen are referred to corresponding operator, and by mutual capacitance layer, multiple touch point is accurately located on screen, reached multiple operator when the enterprising line operate of screen, the operation of user is distinguished by the self-capacitance layer on screen and mutual capacitance layer by electronic equipment.
