First please refer to Fig. 1, Fig. 1 is the schematic diagram of the contactor control device of the embodiment of the present invention.Contactor control device 1 has touch-control sensing unit, and touch-control sensing unit comprises many first direction lines of induction 11, many second direction lines of induction 12, front-end circuit 14 and touch sensings 15 (Controller).Many the first direction line of induction 11 is electrically insulated each other with many second direction lines of induction 12, many the first direction line of induction 11 is set parallel to each other and extends (such as X-direction) with first direction, many the second direction line of induction 12 is set parallel to each other and extends (such as Y-direction) with second direction, many the first direction line of induction 11 has multiple staggered part that overlaps each other, to form multiple induction point 13 by this with many second direction lines of induction 12 on plane graph.Many the first direction line of induction 11 is electrically connected front-end circuit 14, and front-end circuit 14 is electrically connected touch sensing 15.
When copper post 16 or other touch control objects touch multiple induction point 13 at least one of them, then the induced electricity capacitance of touched induction point 13 correspondence has and changed.Therefore, front-end circuit 14 can obtain the induction amount that copper post 16 touches induction point 13, and wherein induction amount is the inductance capacitance variable quantity representing the touched front and back of induction point 13.In addition, in this embodiment, the horizontal range between each induction point 13 is at least 6 centimetres, and is such as 12 centimetres in order to the distance of two the copper posts 16 testing contactor control device 1, but the present invention is not as limit.
In addition, touch sensing 15 comprises a multiple or circuit to perform the multiple touch control methods in the embodiment of the present invention.Touch sensing 15 obtains the induction amount of each induction point 13 with specific scanning sequency (such as from top to bottom column by column by left and the right side is scanned), and finds out multiple induction points that induction amount is greater than induction critical value.Then, induction amount is greater than described multiple induction points 13 multiple induction point 13 adjacent thereto of induction critical value by touch sensing 15 again induction amount with specific scanning sequency is compared, judge whether that the induction point 13 induction amount being greater than induction critical value is judged as peak induction point, multiple induction points 13 that wherein induction amount is greater than the vicinity of described multiple induction points 13 of induction critical value determined by operator scheme, and operator scheme can be the first or second pattern.
For example, in FIG, the induction amount of two induction points 13 of copper post 16 touch-controls is greater than induction critical value, and be also greater than the induction amount of its contiguous induction point 13, therefore the induction measurer of two induction points 13 of copper post 16 touch-controls has peak value, and two induction points 13 of copper post 16 touch-controls can be regarded as peak induction point.In addition, if operator scheme is first mode, and first mode is such as peak-mode looked in X word, then the induction point 13 in the induction point 13 of the vicinity of two induction points 13 of copper post 16 touch-controls upper left corner that is two induction points 13 of copper post 16 touch-controls, the upper right corner, the lower left corner and the lower right corner.If operator scheme is the second pattern, and the second pattern is such as peak-mode looked in cross, then above two induction points 13 that the induction point 13 of the vicinity of two induction points 13 of copper post 16 touch-controls is copper post 16 touch-controls, below, the induction point 13 on the left side and the right.
If the induction point that induction amount is greater than induction critical value is judged as described peak induction point, then multiple induction points 13 that peak induction point is contiguous can be judged as described multiple peak induction point by touch sensing 15 forcibly, and the described induction point wherein closing on peak induction point determined by operator scheme.Such as, in Fig. 1, when the preset mode of operator scheme is first mode (as peak-mode looked in X word), then two induction points 13 of copper post 16 touch-controls the right, the left side, will not be judged as peak induction point forcibly with the induction point of four below 13 above.When the pattern of operator scheme is the second pattern (as peak-mode looked in cross), then four induction points 13 in the upper right corner of two induction points 13 of copper post 16 touch-controls, the upper left corner, the lower right corner and the lower left corner will not be judged as peak induction point forcibly.Then, touch sensing 15 can according to the determining positions touch trajectory of each peak induction point.
In an alternative embodiment of the invention, with specific scanning sequency, touch sensing 15 also can judge whether one of them the induction amount of described multiple induction points 13 of the vicinity of described multiple peak induction point is greater than the induction amount of described peak induction point, wherein described multiple induction points 13 of contiguous described peak induction point make to be preset as the first or second pattern according to specific scanning sequency and operator scheme and decide.If one of them induction amount of described multiple induction point of contiguous described peak induction point is greater than the induction amount of described peak induction point, then described peak induction point is not judged as peak induction point, and the maximum of the induction amount of described multiple induction points 13 contiguous for described peak induction point is judged as described peak induction point.In other words, if the induction amount of described peak induction point is less than the induction amount of its contiguous multiple induction points 13 one of them, then current peak induction point will be moved to the maximum of the induction amount of its contiguous multiple induction points 13.
For example, in Fig. 1, suppose that specific scanning sequency is for from top to bottom the right side is scanned by a left side column by column, and described operator scheme is preset as first mode, if the right of the induction point 13 of copper post 16 touch-controls is greater than the induction point 13 of copper post 16 touch-controls with the induction amount of one of them of induction point 13 below, then peak induction point is judged as that the greater is measured with induction in induction point 13 below in the right of the induction point 13 of copper post 16 touch-controls, and the induction point 13 of copper post 16 touch-controls is not judged as peak induction point.
Suppose that specific scanning sequency is for from top to bottom the right side is scanned by a left side column by column, and described operator scheme is preset as the second pattern, if the induction amount of one of them of the lower right corner of the induction point 13 of copper post 16 touch-controls and the induction point 13 in the lower left corner is greater than the induction point 13 of copper post 16 touch-controls, then peak induction point is judged as that in the lower right corner of induction point 13 of copper post 16 touch-controls and the induction point 13 in the lower left corner, the greater is measured in induction, and the induction point 13 of copper post 16 touch-controls is not judged as peak induction point.
Suppose that specific scanning sequency is for from bottom to top the right side is scanned by a left side column by column, and described operator scheme is preset as the second pattern, if the induction amount of one of them of the upper right corner of the induction point 13 of copper post 16 touch-controls and the induction point 13 in the upper left corner is greater than the induction point 13 of copper post 16 touch-controls, then peak induction point is judged as that in the upper right corner of induction point 13 of copper post 16 touch-controls and the induction point 13 in the upper left corner, the greater is measured in induction, and the induction point 13 of copper post 16 touch-controls is not judged as peak induction point.
In an alternative embodiment of the invention, touch sensing 15 can also use peak value fusion function (peak merge function) optionally by described multiple peak induction point at least one of them is not judged as peak induction point.For example, if the difference of the induction amount of the induction amount of at least one induction point between two peak induction points and described two peak induction points little (also namely the induction amount of described two peak induction points and at least one induction point between it changes very little), then described two peak induction points can be merged into a peak induction point by peak value fusion function.
Because operator scheme can be first mode or the second pattern, and first mode and the second pattern are applicable to the line (level determining different trend, vertical or diagonal) touch trajectory, therefore in an alternative embodiment of the invention, touch sensing 15 can also according to described multiple peak induction point move towards judge whether operator scheme should carry out switching maybe need not switching, wherein move towards to judge touch trajectory be level or vertical line and cornerwise one of them, if therefore current operator scheme is not suitable for determining touch trajectory, then always can switch operator scheme according to walking of judging.If touch sensing 15 judges that this operator scheme should switch, then accordingly operator scheme is switched, and touch sensing 15 will find peak induction point with the operator scheme after switching again, and decide touch trajectory according to the peak induction point again found out.There is the obtain manner about trend to describe in detail in follow-up content, first do not describe in detail at this.
The contactor control device being then please the embodiment of the present invention with reference to Fig. 2 A and Fig. 2 B, Fig. 2 A uses first mode to judge the schematic diagram of peak induction point, and the contactor control device that Fig. 2 B is the embodiment of the present invention uses the schematic diagram of the second mode decision peak induction point.In Fig. 2 A and Fig. 2 B, first mode and the second pattern are respectively X word and look for peak-mode and cross to look for peak-mode.But it should be noted that, the type of first mode and the second pattern is also not used to limit the present invention.
In Fig. 2 A, when operator scheme is first mode, whether the induction amount dv (x, y) of the induction point of touch sensing meeting comparison position (x, y) is greater than induction critical value.If position (x, the induction amount dv (x of induction point y), y) induction critical value is greater than, then touch sensing meeting comparison position (x, the induction amount dv (x of induction point y), y) with position (x-1, y-1), (x+1, y-1), the induction amount dv (x-1 of the induction point of (x-1, y+1), (x+1, y+1), y-1), dv (x+1, y-1), dv (x-1, y+1), dv (x+1, y+1).If position (x, the induction amount dv (x of induction point y), y) position (x-1 is all greater than, y-1), (x+1, y-1), (x-1, y+1), (x+1, the induction amount dv (x-1 of induction point y+1), y-1), dv (x+1, y-1), dv (x-1, y+1), dv (x+1, y+1), then the induction point of position (x, y) is judged as peak induction point by touch sensing.In other words, when operator scheme is first mode, touch sensing can compare the induction amount of four induction points that induction amount is greater than the induction induction point of critical value and the upper left corner thereof, the upper right corner, the lower left corner, the lower right corner, to judge whether that described induction point induction amount being greater than induction critical value is judged as peak induction point.
In Fig. 2 B, when operator scheme is the second pattern, whether the induction amount dv (x, y) of the induction point of touch sensing meeting comparison position (x, y) is greater than induction critical value.If position (x, the induction amount dv (x of induction point y), y) induction critical value is greater than, then touch sensing meeting comparison position (x, the induction amount dv (x of induction point y), y) with position (x, y-1), (x, y+1), the induction amount dv (x of the induction point of (x-1, y), (x+1, y), y-1), dv (x, y+1), dv (x-1, y), dv (x+1, y).If the induction amount dv (x, y) of the induction point of position (x, y) is all greater than position, position (x, y-1), (x, y+1), the induction amount dv (x of the induction point of (x-1, y), (x+1, y), y-1), dv (x, y+1), dv (x-1, y), dv (x+1, y), then the induction point of position (x, y) is judged as peak induction point by touch sensing.In other words, when operator scheme is the second pattern, touch sensing can compare the induction amount that induction amount is greater than the induction induction point of critical value and the left side thereof, the right, four induction points, above below, to judge whether that described induction point induction amount being greater than induction critical value is judged as peak induction point.
Subsidiary one carries, and first mode is suitable for the touch trajectory determining to draw horizontal or vertical line, but the second pattern is then suitable for determining to draw cornerwise touch trajectory.Therefore, touch sensing 15 can according to walk always to judge touch trajectory be whether draw horizontal or vertical line with draw cornerwise one of them.If by moving towards to judge that touch trajectory is as drawing horizontal or vertical line, and operator scheme is first mode, then touch sensing 15 will maintain first mode, that is need not switching operation modes.If by moving towards to judge that touch trajectory is as drawing horizontal or vertical line, and operator scheme is the second pattern, then touch sensing 15 will switch to first mode, to obtain comparatively accurate touch trajectory.If by moving towards to judge that touch trajectory is as drawing diagonal, and operator scheme is the second pattern, then touch sensing 15 will maintain the second pattern, also namely need not switching operation modes.If by moving towards to judge that touch trajectory is as drawing diagonal, and operator scheme is first mode, then touch sensing 15 will switch to the second pattern, to obtain comparatively accurate touch trajectory.
Please then with reference to the flow chart that Fig. 3, Fig. 3 are the touch control methods of the embodiment of the present invention.First, in step S31, touch sensing obtains the induction amount of each induction point with a specific scanning sequency, and find out induction amount be greater than induction critical value multiple induction points.Specific scanning sequency such as by upper and under column by column by left and the right side is scanned, but the present invention is not as limit.In other embodiments, specific scanning sequency also can such as from top to bottom by the right side, a left side is scanned column by column.
Then, in step s 32, induction amount is greater than described induction point multiple induction point adjacent thereto of induction critical value by touch sensing induction amount with specific scanning sequency is compared, judge whether that described induction point induction amount being greater than induction critical value is judged as peak induction point, the multiple induction points wherein induction amount being greater than the vicinity of the described induction point of induction critical value determined by operator scheme, and operator scheme is first mode or the second pattern.If the induction amount of described induction point that induction amount is greater than induction critical value is all greater than multiple induction points of the vicinity of described induction point, (such as: when operator scheme is first mode, then contiguous multiple induction points are four induction points in the upper left corner, the upper right corner, the lower left corner, the lower right corner; Or when operator scheme is the second pattern, then contiguous multiple induction points are the left side, the right, four induction points below, above) induction amount, then the described induction point described induction amount being greater than induction critical value is judged as peak threshold point.If the induction amount of described induction point that induction amount is greater than induction critical value is not all greater than the induction amount of multiple induction points of the vicinity of described induction point, then the described induction point described induction amount not being greater than induction critical value is judged as peak induction point.
Then, in step S33, if the induction point that induction amount is greater than induction critical value is judged as peak induction point, then touch sensing is not judged as described multiple peak induction point by mandatory for multiple induction points of contiguous described peak induction point, and wherein multiple induction points of contiguous described peak induction point determined by operator scheme.When operator scheme is first mode, multiple induction points of contiguous described peak induction point are above described peak induction point, below, the induction point on the left side and the right.When operator scheme is the second pattern, multiple induction points of contiguous described peak induction point are the induction point in the upper right corner of described peak induction point, the upper left corner, the lower left corner and the lower right corner.Step S33 can suitable choice for use or need not.Then, in step s 35, touch sensing is according to the determining positions touch trajectory of each peak induction point.
For example, when operator scheme is first mode, and specific scanning sequency is for when from top to bottom by a left side, the right side is scanned column by column, then in step s 32, multiple induction points contiguous in same row may be judged as peak induction point, or may be judged as peak induction point with multiple induction points contiguous in a line, such as, in step s 32, be judged the right of the induction point of peak induction point, the left side, induction point above, below also may be judged as peak induction point.Therefore, in step S33, touch sensing according to specific scanning sequency, scanning peak induction point, with by current scanline to the right of peak induction point, the left side, above, below induction point be not forcibly judged as peak induction point.When operator scheme is the second pattern, and specific scanning sequency is for when from top to bottom by a left side, the right side is scanned column by column, then in step s 32, in online with pair of horns, contiguous multiple induction points may be judged as peak induction point, such as, in step s 32, be judged the upper right corner of the induction point of peak induction point, the lower left corner, the upper left corner, the lower right corner induction point also may be judged as peak induction point.Therefore, in step S33, touch sensing according to specific scanning sequency, scanning peak induction point, with by current scanline to the upper right corner of peak induction point, the lower left corner, the upper left corner, the lower right corner induction point be not forcibly judged as peak induction point
Note that the touch control method of Fig. 3 can also comprise step S34 at this.In step S34, according to peak value fusion function selectivity, touch sensing judges whether described multiple peak induction point is left peak induction point.Then, after step S34, step S35 will be performed.Peak value fusion function in order to judge induction amount and the changing condition of multiple sensitive amount between it of two peak induction points, to determine whether two peak induction points are merged into a peak induction point.Note that step S34 is not the steps necessary of the touch control method of Fig. 3 at this, it also can remove in the touch control method of Fig. 3.
Then, please refer to the schematic diagram that Fig. 4 A and Fig. 4 B, Fig. 4 A and Fig. 4 B is the induction amount of multiple induction points in the contactor control device of the embodiment of the present invention.In the embodiment of Fig. 4 A and Fig. 4 B, operator scheme is first mode, specific scanning sequency is for from top to bottom by a left side, the right side is scanned column by column, touch sensing uses the touch control method of Fig. 3, and the copper post that line test mode is respectively 12,12,12,12 and 24 centimetres with five center distance carries out vertical score.
Position (X in Fig. 4 A 1, Y 1) ~ (X 10, Y 10) the induction amount of multiple induction points be greater than critical influence value, and position (X 1, Y 1) ~ (X 10, Y 10) the induction amount of each of multiple induction points be greater than the induction amount of induction point in its upper left corner, the upper right corner, the lower left corner and the lower right corner, therefore position (X 1, Y 1) ~ (X 10, Y 10) multiple induction points in above-mentioned steps S32, be judged as peak induction point.Then, in step S33, touch sensing according to specific scanning sequency to position (X 1, Y 1) ~ (X 10, Y 10) multiple peak induction points scan, by above current scanline to peak induction point, below, the right, the left side induction point be not forcibly judged as peak induction point (as shown in Figure 4 B).
For example, position (X in Fig. 4 B 1, Y 1) peak induction point can first be scanned, although the induction point (position (X on the right of it 2, Y 2) induction point) though step S32 is judged peak induction point, in step S33, position (X in Fig. 4 B 2, Y 2) induction point be not then forcibly judged as peak induction point.Again, due to position (X 2, Y 2) induction point be not judged as peak induction point, therefore position (X 3, Y 3) induction point would not because of position (X 2, Y 2) induction point be the impact of peak induction point and be not judged as peak induction point, therefore position (X 3, Y 3) induction point can be judged as peak induction point.In like manner known, in Fig. 4 B, be judged other multiple induction points (position (X of peak induction point in step S32 4, Y 4), (X 6, Y 6), (X 8, Y 8) and (X 10, Y 10) induction point) in step S33, forcibly will not be judged as peak induction point.
The contactor control device being then please the embodiment of the present invention with reference to Fig. 5, Fig. 5 presents the schematic diagram of the touch trajectory of vertical score according to aforementioned embodiments.When user carries out vertical score in contactor control device, then the touch control method of Fig. 3 is when operator scheme is first mode, and its touch trajectory judged is as shown in Figure 5.In addition, other embodiments of the invention also proposed another kind of touch control method, and it can have the situation of slightly shaking to improve for the touch trajectory of Fig. 5.
Please refer to Fig. 6, Fig. 6 is the flow chart of the touch control method of another embodiment of the present invention.The touch control method of Fig. 6 comprises step S61 ~ S65, and wherein step S61 ~ S63 is identical respectively with step S35 with the step S31 ~ S33 of step S65 and Fig. 3, therefore identical step content will repeat no more.In step S64, touch sensing judges with specific scanning sequency whether one of them the induction amount of described multiple induction point of the vicinity of described multiple peak induction point is greater than the induction amount of described peak induction point, if one of them induction amount of the contiguous described multiple induction point of described peak induction point is greater than the induction amount of described peak induction point, then described peak induction point is not judged as peak induction point, and the maximum of the induction amount of described multiple induction point contiguous for described peak induction point is judged as described peak induction point, wherein described multiple induction point of contiguous described peak induction point is preset as the first or second pattern according to described specific scanning sequency and operator scheme determined.
When specific scanning sequency is for from top to bottom by a left side, the right side is scanned column by column, and operator scheme is preset as first mode, then described multiple induction point that peak induction point is contiguous is herein the right of described peak induction point and two induction points below.When specific scanning sequency is for from top to bottom by a left side, the right side is scanned column by column, and operator scheme is preset as the second pattern, then described multiple induction point that peak induction point is contiguous is herein the lower right corner of described peak induction point and two induction points in the lower left corner.
In more detail, in step S62, the multiple induction points being judged as the vicinity of the induction point of peak induction point are also likely judged as peak induction point.Then, in step S63, touch sensing is with specific scanning sequency, by current scanline to peak induction point near multiple induction points be not judged as peak induction point, therefore current scanline to the induction amount of neighbouring multiple induction point of peak induction point likely can be greater than the induction amount of peak induction point, but it is not but judged as peak induction point by touch sensing.Therefore, in step S64, touch sensing again scans all peak induction points with specific scanning sequency, and inspect current scanline to peak induction point vicinity multiple induction points induction amount at least whether one of them is greater than the induction amount of the peak induction point that current scanline arrives.
If current scanline to peak induction point vicinity multiple induction points induction amount at least one of them is greater than the induction amount of the peak induction point that current scanline arrives, then touch sensing can by current scanline to the induction of multiple induction points of vicinity of peak induction point measure the maximum and be judged as peak induction point, current scanline to peak induction point be not then judged as peak induction point.So, determine that the touch control method than Fig. 3 is determined that the accuracy of track is come high by the accuracy of touch trajectory by the touch control method of step S64, Fig. 6.In addition, it should be noted that, the touch control method of Fig. 6 can also comprise the step S34 of Fig. 3, and the execution sequence of step S34 is between step S64 and S65.
Please refer to Fig. 7 A ~ Fig. 7 C, Fig. 7 A ~ Fig. 7 C is the schematic diagram of the induction amount of multiple induction points in the contactor control device of another embodiment of the present invention.In the embodiment of Fig. 7 A ~ Fig. 7 C, operator scheme is preset as first mode, specific scanning sequency is for from top to bottom by a left side, the right side is scanned column by column, touch sensing uses the touch control method of Fig. 6, and the copper post that line test mode is respectively 12,12,12,12 and 24 centimetres with five center distance carries out vertical score.
In Fig. 7 A, position (X 1, Y 1) ~ (X 10, Y 10) multiple induction points in above-mentioned steps S62, be judged as peak induction point, then, in step S63, touch sensing scans according to specific scanning sequency, by above current scanline to peak induction point, below, the right, the left side induction point be not forcibly judged as peak induction point.Therefore, position (X in Fig. 7 B 1, Y 1) peak induction point can first be scanned to, although the induction point (position (X on the right of it 2, Y 2) induction point) though step S62 is judged peak induction point, in step S63, position (X in Fig. 7 B 2, Y 2) induction point be not then forcibly judged as peak induction point.Again, due to position (X 2, Y 2) induction point be not judged as peak induction point, therefore position (X 3, Y 3) induction point would not because of position (X 2, Y 2) induction point be the impact of peak induction point and be not judged as peak induction point, therefore position (X 3, Y 3) induction point can be judged as peak induction point.In like manner known, in Fig. 7 B, be judged other multiple induction points (position (X of peak induction point in step S62 4, Y 4), (X 6, Y 6), (X 8, Y 8) and (X 10, Y 10) induction point) in step S63, forcibly will not be judged as peak induction point.
Please note at this, because operator scheme is preset as first mode, and scanning sequency is for from top to bottom by a left side, the right side is scanned column by column, even if therefore current scanline to peak induction point the right with below one of them of induction amount of induction point be greater than the induction amount of current scanline to peak induction point, but step S63 by its current scanline to peak induction point the right with below induction point be not forcibly judged as peak induction point, therefore the touch trajectory that result in as Fig. 5 has the situation of slightly shaking.Therefore, need to inspect current scanline to peak induction point the right with below one of them of induction amount of induction point whether be greater than the induction amount of current scanline to peak induction point, to determine whether current peak induction point is not judged as that peak induction point is judged as peak induction point with the maximum induction amount on the right of peak induction point and induction point being below greater than the induction amount of peak induction point.So, the situation that touch trajectory is shaken slightly can effectively be improved.
In addition on the one hand, can learn from above, in step 64, described multiple induction point of contiguous described peak induction point is preset as the first or second pattern according to described specific scanning sequency and operator scheme determined.If scanning sequency is for from top to bottom by the right side, a left side is scanned column by column, and operator scheme is preset as first mode, then current scanline to peak induction point the left side with below one of them of induction amount of induction point be greater than current scanline and can be judged as peak induction point to the induction amount person of peak induction point, therefore, in in the case, described multiple induction point of contiguous described peak induction point is the left side of peak induction point and induction point below.
If scanning sequency is for from bottom to top by a left side, the right side is scanned column by column, and operator scheme is preset as first mode, then be greater than current scanline above current scanline to peak induction point with one of them of the induction amount of the induction point on the right and can be judged as peak induction point to the induction amount person of peak induction point, therefore, in in the case, described multiple induction point of contiguous described peak induction point is the right of peak induction point and induction point above.If scanning sequency is for from bottom to top by the right side, a left side is scanned column by column, and operator scheme is preset as first mode, then current scanline to peak induction point the left side with above one of them of induction amount of induction point be greater than current scanline and can be judged as peak induction point to the induction amount person of peak induction point, therefore, in in the case, described multiple induction point of contiguous described peak induction point is the left side of peak induction point and induction point above.
Shown in Fig. 7 C, in step S64, position (X 1, Y 1) peak induction point can first be scanned, due to position (X 1, Y 1) peak induction point on the right of induction point (position (X 2, Y 2) induction point) induction amount be greater than position (X 1, Y 1) the induction amount of peak induction point, therefore, by position (X 1, Y 1) peak induction point be not judged as peak induction point, and by (X 2, Y 2) the peak induction point of induction point be judged as peak induction point.Then, position (X 3, Y 3) peak induction point can be scanned, but position (X 3, Y 3) the right of peak induction point be not greater than position (X with the induction amount of induction point below 3, Y 3) the induction amount of peak induction point, therefore position (X 3, Y 3) peak induction point do not need not to be judged as peak induction point.In like manner known, position (X 9, Y 9) peak induction point will be judged as peak induction point, position (X 10, Y 10) the peak induction point of induction point will be judged as peak induction point, in addition, position (X 5, Y 5) and (X 7, Y 7) peak induction point do not need not to be judged as peak induction point.
Please refer to Fig. 8 A ~ Fig. 8 C, Fig. 8 A ~ Fig. 8 C is the schematic diagram of the induction amount of multiple induction points in the contactor control device of another embodiment of the present invention.In the embodiment of Fig. 8 A ~ Fig. 8 C, operator scheme is preset as the second pattern, specific scanning sequency is for from top to bottom to scan from left to right or from right to left column by column, touch sensing uses the touch control method of Fig. 6, and the copper post that line test mode is respectively 12,12,12,12 and 24 centimetres with five center distance carries out diagonal line.
In Fig. 8 A, position (X 1, Y 1) ~ (X 5, Y 5) multiple induction points in above-mentioned steps S62, be judged as peak induction point, then, in step S63, touch sensing scans according to specific scanning sequency, by current scanline to the upper left corner of peak induction point, the lower right corner, the upper right corner, the lower left corner induction point be not forcibly judged as peak induction point.Therefore, in Fig. 8 B as position (X 3, Y 3) peak induction point when can be scanned, although the induction point in its lower left corner (position (X 2, Y 2) induction point) be judged peak induction point in step S62, but in step S63, position (X in Fig. 8 B 2, Y 2) induction point be not then forcibly judged as peak induction point.
Please note at this; because operator scheme is preset as the second pattern; and scanning sequency is for from top to bottom by a left side, the right side is scanned column by column; even if therefore current scanline is greater than the induction amount of current scanline to peak induction point to the induction amount of the induction point in the lower right corner of peak induction point and the lower left corner one of them; but its current scanline is not forcibly judged as peak induction point to the lower right corner of peak induction point and the induction point in the lower left corner by step S63, therefore the touch trajectory finally judged may be caused to have the situation of slightly shaking.Therefore, need to inspect current scanline and whether be greater than the induction amount of current scanline to peak induction point, to determine whether current peak induction point is not judged as that peak induction point is judged as peak induction point with the maximum induction amount in the lower right corner of peak induction point and the induction point in the lower left corner being greater than the induction amount of peak induction point to one of them of the induction amount of the induction point in the lower right corner of peak induction point and the lower left corner.So, the situation that touch trajectory is shaken slightly can effectively be improved.
In addition on the one hand, can learn from above, in step 64, described multiple induction point of contiguous described peak induction point is preset as the first or second pattern according to described specific scanning sequency and operator scheme determined.
If scanning sequency is for from bottom to top to scan from left to right or from right to left column by column, and operator scheme is preset as the second pattern, then current scanline is greater than current scanline to one of them of the induction amount of the induction point in the upper right corner of peak induction point and the upper left corner and can be judged as peak induction point to the induction amount person of peak induction point, therefore, in in the case, described multiple induction point of contiguous described peak induction point is the upper right corner of peak induction point and the induction point in the upper left corner.
Shown in Fig. 8 C, in step S64, position (X 5, Y 5) peak induction point can first be scanned, but position (X 5, Y 5) the lower right corner of peak induction point and the induction amount of the induction point in the lower left corner be not greater than position (X 5, Y 5) the induction amount of peak induction point, therefore position (X 5, Y 5) peak induction point do not need not to be judged as peak induction point.Then, position (X 4, Y 4) peak induction point can be scanned, but position (X 4, Y 4) the lower right corner of peak induction point and the induction amount of the induction point in the lower left corner be not greater than position (X 4, Y 4) the induction amount of peak induction point, therefore position (X 4, Y 4) peak induction point do not need not to be judged as peak induction point.Then, as position (X 3, Y 3) peak induction point when can be scanned, due to position (X 3, Y 3) the induction point (position (X in the peak induction point lower left corner 2, Y 2) induction point) induction amount be greater than position (X 3, Y 3) the induction amount of peak induction point, therefore, by position (X 3, Y 3) peak induction point be not judged as peak induction point, and by (X 2, Y 2) the peak induction point of induction point be judged as peak induction point.Afterwards, position (X 1, Y 1) peak induction point can be scanned, but position (X 1, Y 1) the lower right corner of peak induction point and the induction amount of the induction point in the lower left corner be not greater than position (X 1, Y 1) the induction amount of peak induction point, therefore position (X 1, Y 1) peak induction point do not need not to be judged as peak induction point.Please then with reference to Fig. 9 A and Fig. 9 B, Fig. 9 A is the contactor control device of another embodiment of the present invention presents the touch trajectory of vertical score schematic diagram according to aforementioned embodiments, Fig. 9 B is the contactor control device of another embodiment of the present invention the presents diagonal line schematic diagram of touch trajectory according to aforementioned embodiments, wherein the operator scheme of Fig. 9 A corresponds to first mode, and the operator scheme of Fig. 9 B corresponds to the second pattern.Can be learnt by the touch trajectory of Fig. 9 A and 9B, the touch trajectory that the touch control method that the touch control method of Fig. 6 can improve Fig. 3 effectively determines has the situation of slightly shaking.
In addition, first mode is suitable for the touch trajectory determining to draw horizontal or vertical line, and the second pattern is suitable for determining to draw cornerwise touch trajectory.When current operator scheme is not suitable for determining moving towards of current touch trajectory, need switching operation modes further, to obtain more accurate touch trajectory.Therefore, other embodiments of the invention propose another kind of touch control method, can check that the operator scheme used at present is the need of switching, to obtain more accurate touch trajectory.
Please refer to Figure 10, Figure 10 is the flow chart of the touch control method of another embodiment of the present invention.The touch control method of Figure 10 comprises step S91 ~ S97, and wherein step S91 ~ S94 is identical respectively with step S65 with the step S61 ~ S64 of step S97 and Fig. 6, therefore identical step content will repeat no more.In step S95, touch sensing moves towards to judge whether operator scheme should carry out switching maybe need not switching according to one of described multiple peak induction point.If judge, operator scheme should switch, then perform step S96.If judge, operator scheme need not switch, then perform step S97.In step S96, operator scheme is switched, such as, switch to the second pattern from first mode, or switch to first mode from the second pattern.After step S96, step S91 ~ S94 can be performed again, also namely again obtains described multiple peak induction point with the operator scheme after switching.It is worth mentioning that, the touch control method of Figure 10 can also comprise the step S34 of Fig. 3, and the execution sequence of step S34 is between step S94 and S95, and generally speaking, the touch control method of Figure 10 is also not used to limit the present invention.
What deserves to be explained is, described trend can in order to judge that touch trajectory is level or vertical line or diagonal, and first and second pattern is applicable in order to determine level or vertical line or cornerwise touch trajectory respectively, therefore can determine whether needing switching operation modes or maintaining present operator scheme by trend.When operator scheme is the second pattern, and move towards to judge that touch trajectory is level or vertical line, then operator scheme should switch to first mode.When operator scheme is first mode, and move towards to judge that touch trajectory is diagonal, then operator scheme should switch to the second pattern.When this first mode of operator scheme, and move towards to judge that touch trajectory is level or vertical line, then operator scheme need not switch.When operator scheme is the second pattern, and move towards to judge that touch trajectory is diagonal, then operator scheme need not switch.Note that the acquisition pattern of above-mentioned trend at this and be not used to limit the present invention, such as anyly can judge that the implementation of the trend of touch trajectory all can be applied in the present invention.
For example, above-mentioned trend can be the slope obtained by the position calculation of described multiple peak induction, and slope can in order to determine whether switching operation modes.If slope is less, then the trend of touch trajectory is level or vertical line, therefore operator scheme should switch to first mode or maintain first mode.If slope is comparatively large, then the trend of touch trajectory is diagonal, therefore operator scheme should switch to the second pattern or second pattern of maintenance.
Furthermore, if each of described multiple peak induction point and wherein the horizontal range summation Dx of one and the absolute difference of vertical range summation Dy | Dx-Dy| is less than special value THD, then represent that slope is comparatively large, therefore can judge that operator scheme should switch to the second pattern or second pattern of maintenance.If the absolute difference of the horizontal level distance summation Dx and vertical range summation Dy of each of described multiple peak induction point and wherein one | Dx-Dy| is not less than special value THD, then represent that slope is less, therefore judge that operator scheme should switch to first mode or maintain first mode.The each of described multiple peak induction point with wherein the horizontal range summation Dx of one and the account form of vertical range summation Dy can be as described below, Dx=(Σ | X i-X j|) and Dy=(Σ | Y i-Y j|), wherein i is not equal to j, and i is the index value of one of them peak induction point, and the index value of j multiple peak induction point that is other.
In other embodiments of the present invention, above-mentioned trend also can be decided by the induction amount of multiple induction points of each vicinity of described multiple peak induction point, and multiple induction points of wherein said peak induction point vicinity are determined by specific scanning sequency.When specific scanning sequency is for from top to bottom (or from bottom to top) is column by column by left and the right side is scanned, then multiple induction points that described peak induction point is contiguous are three induction points in the right of described peak induction point, the lower right corner and the upper right corner.When specific scanning sequency is for from top to bottom (or from bottom to top) is column by column by right and a left side is scanned, then multiple induction points that described peak induction point is contiguous are three induction points in the left side of described peak induction point, the lower left corner and the upper left corner.
The wherein a kind of implementation deciding to move towards by the induction amount of multiple induction points of each vicinity by described multiple peak induction point is described as follows, and the present invention is not restricted to this.When specific scanning sequency for from top to bottom (or from bottom to top) column by column by left and the right side is scanned time, and the induction amount of the induction point on the right of any one of described multiple peak induction point is less than the induction amount of the lower right corner of described peak induction point or the induction point in the upper right corner, the trend then representing touch trajectory is diagonal, therefore judges that operator scheme switches to the second pattern or second pattern of maintenance.When the induction amount of the induction point on the right of each of described multiple peak induction point is more than or equal to the induction amount of the lower right corner of described peak induction point and the induction point in the upper right corner, the trend then representing touch trajectory is level or vertical line, therefore judges that operator scheme switches to first mode or maintains first mode.
In addition, the wherein another kind of implementation deciding to move towards by the induction amount of multiple induction points of each vicinity by described multiple peak induction point is described as follows, and the present invention is not restricted to this.The induction amount that the quantity being less than the induction amount of the lower right corner of described peak induction point or the induction point in the upper right corner when the induction amount of the induction point on the right of described multiple peak induction point is more than or equal to the induction point on the right of described multiple peak induction point is greater than the quantity of the induction amount of the lower right corner of described peak induction point and the induction point in the upper right corner, then represent that the trend of touch trajectory is diagonal, therefore operator scheme should switch to the second pattern or second pattern of maintenance.The induction amount that the quantity being less than the induction amount of the lower right corner of described peak induction point or the induction point in the upper right corner when the induction amount of the induction point on the right of described multiple peak induction point is less than the induction point on the right of described multiple peak induction point is greater than the quantity of the induction amount of the lower right corner of described peak induction point and the induction point in the upper right corner, then represent that the trend of touch trajectory is level or vertical line, therefore operator scheme should switch to first mode or maintain first mode.
Figure 11 is the schematic diagram of the induction amount of multiple induction points in the contactor control device of another embodiment of the present invention.In the embodiment of Figure 11, operator scheme is first mode, specific scanning sequency is for from top to bottom by a left side, the right side is scanned column by column, touch sensing uses the touch control method of Figure 10, and the copper post that line test mode is respectively 12,12,12,12 and 24 centimetres with five center distance carries out vertical line line.In Figure 11, the position of multiple peak induction point is respectively (X 1, Y 1), (X 2, Y 2), (X 3, Y 3), (X 4, Y 4), (X 5, Y 5).
For trend for the position calculation by described multiple peak induction and the slope that obtains is described.The horizontal range summation Dx of each of multiple peak induction point and wherein one (Dx=(| X 2-X 1|+| X 3-X 1|+| X 4-X 1|+| X 5-X 1|)=1+3+5+10) be 19, and the vertical range summation Dy of each of multiple peak induction point and wherein one (Dy=(| Y 2-Y 1|+| Y 3-Y 1|+| Y 4-Y 1|+| Y 5-Y 1|)=0+0+0+0) be 0.If suppose, special value THD is 10, the then each of described multiple peak induction point and wherein the horizontal range summation Dx of one and the absolute difference of vertical range summation Dy | Dx-Dy| (| Dx-Dy|=19) be not less than special value THD, then represent slope less (trend of touch trajectory is level or vertical line), therefore judge that operator scheme should maintain first mode.
In addition, to move towards to be decided to be described by the induction amount of the contiguous multiple induction points of each of described multiple peak induction point.Position is (X 1, Y 1) the induction amount (induction amount is c1, adopt hexadecimal) of the right induction point of peak induction point be greater than position for (X 1, Y 1) the upper right corner of peak induction point and the induction amount (induction amount be respectively 19 and 2a) of the induction point in the lower right corner.Position is (X 2, Y 2) the induction amount (induction amount is b4) of the right induction point of peak induction point be greater than position for (X 2, Y 2) the upper right corner of peak induction point and the induction amount (induction amount is respectively 15 and 24) of the induction point in the lower right corner.Position is (X 3, Y 3) the induction amount (induction amount is a9) of the right induction point of peak induction point be greater than position for (X 3, Y 3) the upper right corner of peak induction point and the induction amount (induction amount is respectively d and 27) of the induction point in the lower right corner.Position is (X 4, Y 4) the induction amount (induction amount is a1) of the right induction point of peak induction point be greater than position for (X 4, Y 4) the upper right corner of peak induction point and the induction amount (induction amount is respectively 2 and 31) of the induction point in the lower right corner.Position is (X 5, Y 5) the induction amount (induction amount is 0) of the right induction point of peak induction point equal position for (X 5, Y 5) the upper right corner of peak induction point and the induction amount (induction amount is respectively 0 and 0) of the induction point in the lower right corner.
If the rule taked is: if the induction amount of the induction point on the right of any one of described multiple peak induction point is less than the induction amount of the lower right corner of described peak induction point or the induction point in the upper right corner, namely judge that the trend of touch trajectory is diagonal; And if the induction amount of induction point on the right of described whole peak induction point is all more than or equal to the induction amount of the lower right corner of described peak induction point or the induction point in the upper right corner, namely judges that the trend of touch trajectory is level or vertical line.Therefore, in above-mentioned situation, touch sensing judges that operator scheme should maintain first mode.
Figure 12 A and Figure 12 B is the schematic diagram of the induction amount of multiple induction points in the contactor control device of another embodiment of the present invention.In the embodiment of Figure 12 A, operator scheme is preset as first mode, specific scanning sequency is for from top to bottom by a left side, the right side is scanned column by column, touch sensing uses the touch control method of Figure 10, and the copper post that line test mode is respectively 12,12,12,12 and 24 centimetres with five center distance carries out diagonal line.In Figure 12 A, the position of multiple peak induction point is respectively (X 1, Y 1), (X 2, Y 2), (X 3, Y 3), (X 4, Y 4).
For trend for the position calculation by described multiple peak induction and the slope that obtains is described.The horizontal range summation Dx of each of multiple peak induction point and wherein one (Dx=(| X 2-X 1|+| X 3-X 1|+| X 4-X 1|)=2+5+8) be 15, and the vertical range summation Dy of each of multiple peak induction point and wherein one (Dy=(| Y 2-Y 1|+| Y 3-Y 1|+| Y 4-Y 1|)=1+3+5) be 9.If suppose, special value THD is 10, the then each of described multiple peak induction point and wherein the horizontal range summation Dx of one and the absolute difference of vertical range summation Dy | Dx-Dy| (| Dx-Dy|=6) be less than special value THD, then represent slope comparatively large (trend of touch trajectory is diagonal), therefore judge that operator scheme should switch the second pattern.
The position of the multiple peak induction points after operator scheme switches to the second pattern, as shown in Figure 12 B, obtained is respectively (X ' 1, Y ' 1), (X ' 2, Y ' 2), (X ' 3, Y ' 3), (X ' 4, Y ' 4), (X ' 5, Y ' 5).Now, each and the wherein one of multiple peak induction point horizontal range summation Dx (Dx=(| X ' 2-X ' 1|+| X ' 3-X ' 1|+| X ' 4-X ' 1|+| X ' 5-X ' 1|)=2+3+5+8) be 18, and the vertical range summation Dy of each of multiple peak induction point and wherein one (Dy=(| Y ' 2-Y ' 1|+| Y ' 3-Y ' 1|+| Y ' 4-Y ' 1|+| Y ' 5-Y ' 1|)=1+2+3+5) be 11.If suppose, special value THD is 10, the each of described multiple peak induction point and wherein the horizontal range summation Dx of one and the absolute difference of vertical range summation Dy | Dx-Dy| (| Dx-Dy|=7) be less than special value THD, then represent slope comparatively large (trend controlling track is diagonal).Therefore, operator scheme is maintained the second pattern by touch sensing.
In addition, to move towards to be decided to be described by the induction amount of the contiguous multiple induction points of each of described multiple peak induction point.In Figure 12 A, position is (X 1, Y 1) the induction amount (induction amount is 26, adopt hexadecimal) of the right induction point of peak induction point be less than position for (X 1, Y 1) the upper right corner of peak induction point and one of them (induction amount is respectively b0 and 0) of induction amount of the induction point in the lower right corner.Position is (X 2, Y 2) the induction amount (induction amount is 11) of the right induction point of peak induction point be less than or equal to position for (X 2, Y 2) the upper right corner of peak induction point and one of them (induction amount is respectively b7 and 0) of induction amount of the induction point in the lower right corner.Position is (X 3, Y 3) the induction amount (induction amount is 7c) of the right induction point of peak induction point be greater than position for (X 3, Y 3) the upper right corner of peak induction point and the induction amount (induction amount is respectively 34 and 0) of the induction point in the lower right corner.Position is (X 4, Y 4) the induction amount (induction amount is b1) of the right induction point of peak induction point be greater than position for (X 4, Y 4) the upper right corner of peak induction point and the induction amount of the induction point in the lower right corner (induction amount is respectively 1f and 1 a).
If the rule taked is: if the induction amount of the induction point on the right of any one of described multiple peak induction point is less than the induction amount of the lower right corner of described peak induction point or the induction point in the upper right corner, namely judge that the trend of touch trajectory is diagonal; And if the induction amount of induction point on the right of described whole peak induction point is all more than or equal to the induction amount of the lower right corner of described peak induction point or the induction point in the upper right corner, namely judges that the trend of touch trajectory is level or vertical line.Therefore, in above-mentioned situation, touch sensing judges that operator scheme should switch to the second pattern.
The position of the multiple peak induction points after operator scheme switches to the second pattern, as shown in Figure 12 B, obtained is respectively (X ' 1, Y ' 1), (X ' 2, Y ' 2), (X ' 3, Y ' 3), (X ' 4, Y ' 4), (X ' 5, Y ' 5).Now, position be (X ' 1, Y ' 1) the induction amount (induction amount is 26, adopt hexadecimal) of the right induction point of peak induction point be less than or equal to position for (X ' 1, Y ' 1) the upper right corner of peak induction point and one of them (induction amount is respectively b0 and 0) of induction amount of the induction point in the lower right corner.Position be (X ' 2, Y ' 2) the induction amount (induction amount is 11) of the right induction point of peak induction point be less than or equal to position for (X ' 2, Y ' 2) the upper right corner of peak induction point and one of them (induction amount is respectively b7 and 0) of induction amount of the induction point in the lower right corner.Position be (X ' 3, Y ' 3) the induction amount (induction amount is a7) of the right induction point of peak induction point be greater than position for (X ' 3, Y ' 3) the upper right corner of peak induction point and the induction amount (induction amount is respectively 58 and 0) of the induction point in the lower right corner.Position be (X ' 4, Y ' 4) the induction amount (induction amount is 7c) of the right induction point of peak induction point be greater than position for (X ' 4, Y ' 4) the upper right corner of peak induction point and the induction amount (induction amount is respectively 34 and 0) of the induction point in the lower right corner.Position be (X ' 5, Y ' 5) the induction amount (induction amount is b1) of the right induction point of peak induction point be greater than position for (X ' 5, Y ' 5) the upper right corner of peak induction point and the induction amount (induction amount is respectively 1f and 1a) of the induction point in the lower right corner.
If the rule taked is: if the induction amount of the induction point on the right of any one of described multiple peak induction point is less than the induction amount of the lower right corner of described peak induction point or the induction point in the upper right corner, namely judge that the trend of touch trajectory is diagonal; And if the induction amount of induction point on the right of described whole peak induction point is all more than or equal to the induction amount of the lower right corner of described peak induction point or the induction point in the upper right corner, namely judges that the trend of touch trajectory is level or vertical line.Therefore, in above-mentioned situation, touch sensing judges that operator scheme maintains the second pattern.
Figure 13 A and Figure 13 B is the schematic diagram of the induction amount of multiple induction points in the contactor control device of another embodiment of the present invention.In the embodiment of Figure 13 A, operator scheme is preset as first mode, specific scanning sequency is for from top to bottom by a left side, the right side is scanned column by column, touch sensing uses the touch control method of Figure 10, and the copper post that line test mode is respectively 12,12,12,12 and 24 centimetres with five center distance carries out vertical line line.
In Figure 13 A, the contactor control device chip (also namely having plural touch sensing) of more than two processes the induction point of zones of different, therefore, the induction amount of the induction amount of multiple induction points in primary area and multiple induction points of catchment area can be stored in storage element, wherein primary area is except storing the induction amount of multiple induction points of master chip process, also be configured with the induction amount of storage compartment catchment area, part district, to enable primary area chip judge peak induction point smoothly, and catchment area stores the induction amount of multiple induction points of slaves chips process.In the embodiment of Figure 13 A, in primary area, the position of multiple peak induction point is respectively (X 1, Y 1), (X 2, Y 2), (X 3, Y 3), (X 4, Y 4), and in catchment area the position of multiple peak induction point be respectively (X ' 1, Y ' 1), (X ' 2, Y ' 2), (X ' 3, Y ' 3).
Because part district is difficult to the size defining special value THD, therefore use trend for the position calculation by described multiple peak induction and the practice of slope that obtains may cause vertical line to be merged, cause erroneous judgement.In addition, in primary area, if the angle of diagonal line is little, the each of described multiple peak induction point and wherein the horizontal range summation Dx of one and the absolute difference of vertical range summation Dy may be caused | Dx-Dy| is not less than special value THD, diagonal is caused to be merged, or primary area only has a peak induction point, and causes judging touch trajectory.
For trend for the position calculation by described multiple peak induction and the slope that obtains is described.In Figure 13 A, the horizontal range summation Dx of each of multiple peak induction points in primary area and wherein one (Dx=(| X 2-X 1|+| X 3-X 1|+| X 4-X 1|)=2+3+5) be 10, and the vertical range summation Dy of each of multiple peak induction points in primary area and wherein one (Dy=(| Y 2-Y 1|+| Y 3-Y 1|+| Y 4-Y 1|)=0+0+0) be 0.If suppose, special value THD is 11, the then each of described multiple peak induction points in primary area and wherein the horizontal range summation Dx of one and the absolute difference of vertical range summation Dy | Dx-Dy| (| Dx-Dy|=10) be less than special value THD, then represent moving towards misjudged and breaking as diagonal of touch trajectory, therefore operator scheme can be switched the second pattern by master chip mistakenly.
In addition, in Figure 13 A, the horizontal range summation Dx of each of multiple peak induction points of catchment area and wherein one (Dx=(| X ' 2-X ' 1|+| X ' 3-X ' 1|)=2+6) be 8, and the vertical range summation Dy of each of multiple peak induction points of catchment area and wherein one (Dy=(| Y ' 2-Y ' 1|+| Y ' 3-Y ' 1|)=0+1) be 1.If suppose, special value THD is 11, the then each of described multiple peak induction points of catchment area and wherein the horizontal range summation Dx of one and the absolute difference of vertical range summation Dy | Dx-Dy| (| Dx-Dy|=7) be less than special value THD, then represent moving towards misjudged and breaking as diagonal of touch trajectory, therefore operator scheme can be switched the second pattern by slaves chips mistakenly.
After operator scheme switches to the second pattern, as shown in Figure 13 B, the position of peak induction point that obtains, primary area for (X ' ' 1, Y ' ' 1), and the position of the peak induction point that catchment area obtains (X ' ' ' 1, Y ' ' ' 1), (X ' ' ' 2, Y ' ' ' 2).Peak induction due to primary area is counted out not, therefore master chip cannot judge touch trajectory.In addition, because touch trajectory can be judged as that diagonal is rule by slaves chips mistakenly.Generally, master chip and slaves chips cannot obtain the touch trajectory that vertical line is rule smoothly.
In contactor control device processes the induction point of zones of different with the chip of more than two when, preferably, embodiment of the present invention suggestion uses the mode moving towards to be decided by the induction amount of the contiguous multiple induction points of each of described multiple peak induction point to judge whether operator scheme should switch or maintain.
Decide to be described for the induction amount of trend by multiple induction points of each vicinity of described multiple peak induction point.As shown in FIG. 13A, primary area meta is set to (X 1, Y 1) the induction amount (induction amount is 9d, adopt hexadecimal) of the right induction point of peak induction point be greater than position for (X 1, Y 1) the upper right corner of peak induction point and the induction amount (induction amount is respectively 62 and 0) of the induction point in the lower right corner.Primary area meta is set to (X 2, Y 2) the induction amount (induction amount is 91) of the right induction point of peak induction point be greater than position for (X 2, Y 2) the upper right corner of peak induction point and the induction amount (induction amount is respectively 66 and 0) of the induction point in the lower right corner.Primary area meta is set to (X 3, Y 3) the induction amount (induction amount is 86) of the right induction point of peak induction point be greater than position for (X 3, Y 3) the upper right corner of peak induction point and the induction amount (induction amount is respectively 60 and 0) of the induction point in the lower right corner.Primary area meta is set to (X 4, Y 4) the right of peak induction point, the upper right corner and the lower right corner not there is induction point, therefore need not compare.
If the rule taked is: if the induction amount of the induction point on the right of any one of described multiple peak induction point is less than the induction amount of the lower right corner of described peak induction point or the induction point in the upper right corner, namely judge that the trend of touch trajectory is diagonal; And if the induction amount of induction point on the right of described whole peak induction point is all more than or equal to the induction amount of the lower right corner of described peak induction point or the induction point in the upper right corner, namely judges that the trend of touch trajectory is level or vertical line.Therefore, in above-mentioned situation, operator scheme can be maintained first mode by master chip.
As shown in FIG. 13A, catchment area meta be set to (X ' 1, Y ' 1) the induction amount (induction amount is 86, adopt hexadecimal) of the right induction point of peak induction point be greater than position for (X ' 1, Y ' 1) the upper right corner of peak induction point and the induction amount (induction amount is respectively 60 and 0) of the induction point in the lower right corner.Catchment area meta is set to (X ' 2, Y ' 2) the induction amount (induction amount is 81) of the right induction point of peak induction point be greater than position for (X ' 2, Y ' 2) the upper right corner of peak induction point and the induction amount (induction amount is respectively 66 and 0) of the induction point in the lower right corner.Catchment area meta is set to (X ' 3, Y ' 3) the induction amount (induction amount is 90) of the right induction point of peak induction point be greater than position for (X ' 3, Y ' 3) the upper right corner of peak induction point and the induction amount (induction amount is respectively 0 and 81) of the induction point in the lower right corner.
If the rule taked is: if the induction amount of the induction point on the right of any one of described multiple peak induction point is less than the induction amount of the lower right corner of described peak induction point or the induction point in the upper right corner, namely judge that the trend of touch trajectory is diagonal; And if the induction amount of induction point on the right of described whole peak induction point is all more than or equal to the induction amount of the lower right corner of described peak induction point or the induction point in the upper right corner, namely judges that the trend of touch trajectory is level or vertical line.Therefore, in above-mentioned situation, slaves chips can judge that operator scheme should maintain first mode.
Then the peak induction point that part district and catchment area are repeated to locate by master chip and slaves chips merges (i.e. position (X in part district 3, Y 3) and (X 4, Y 4) peak induction point can respectively with position in catchment area (X ' 1, Y ' 1) with (X ' 2, Y ' 2) peak induction point merge), and remaining five peak induction points (result after the not shown fusion of Figure 13 A) after merging, correctly to determine the touch trajectory of vertical score by this according to multiple peak induction point.
