Embodiment
The present invention is described in detail below in conjunction with drawings and Examples:
Consult Fig. 1, the present invention reports the preferred embodiment of point apparatus to be applicable to a display system 100, and this display system 100 comprises a panel 1, a panel controller 2 and a processor 3, and panel controller 2 comprises receiving element 21 and this newspaper point apparatus 20.
As shown in Figure 2, panel 1 comprises a matrix 11, a plurality of inductor 12 and a deckle board 13, and wherein these inductors 12 are arranged on matrix 11, and deckle board 13 superpositions are on these inductors 12 and partly cover those inductors 12 that are positioned at side.And panel 1 also comprises a display surface 15 that is defined by deckle board 13, and the first axle element and the usually expression jointly of the second axle unit of a coordinate can be used in the arbitrary position on display surface 15.
Preferably, this panel 1 is a capacitance type touch-control panel, comprises the individual induction module 17 of as shown in Figure 3 (M+1) and (N+1) individual induction module 18.These induction modules 17 are disposed on the first axle element x along first direction X
m=m * d place, these induction modules 18 are disposed on the second axle element y along second direction Y
n=n * d place, m=0～M, n=0～N, d are the induction module spacing, and d＞0.
Each induction module 17 has a plurality of aforementioned inductors 12 of arranging along second direction Y, and each induction module 18 has a plurality of aforementioned inductors 12 of arranging along first direction X.And for ease of expression, Fig. 3 draws with M=5 and N=4.
When external force applies pressure to the display surface 15 of panel 1, each induction module 17,18 can be sent a sense data that represents sensed intensities to receiving element 21, calculates for newspaper point apparatus 20 that on display surface 15, which coordinate is clicked.And newspaper point apparatus 20 can provide this to click coordinate to processor 3 when a newspaper point request of receiving self processor 3, makes it carry out subsequent job.Preferably, these induction modules 17,18 provide the frequency of sense data higher than the generation frequency that clicks coordinate, and click the generation frequency of coordinate higher than the frequency of newspaper point request.
Because the preferred embodiment of reporting the performed newspaper point methods of point apparatus 20 is to calculate with identical flow process the first axle element and the second axle element that clicks coordinate, so this paper only describes for the first axle element, and hypothesis display surface 15 corresponding the first axle elements 0 of energy, 1,2,3 ... X, m induction module is located at the first axle element x
m=m * d place, and X=x
M=M * d.
Generally, the user can press display surface 15 with finger tip or pointer, so on transverse axis, maximum 5 adjacent induction modules 17 sense pressure, and the induction module 17 in the middle of occuping can record the sense data of higher value.But, if press points is partial to the side of display surface 15, the sense data of side induction module 17 may be because of suffering deckle board 13 cover and diminish, so newspaper point apparatus 20 can be processed side induction module 17 especially when reckoning clicks coordinate.
Specifically, as shown in Figure 4, newspaper point apparatus 20 comprises a selected cell 22, a compensation deals unit 23, an arithmetic element 25, a border processing unit 26, and a setup unit 27.As shown in Figure 5, the newspaper point methods comprises the following steps:
Step 70: setup unit 27 is set each calculating when clicking coordinate at most with reference to (2C+1) individual induction module 17.Preferably, this example is set C=2, but also can adopt other values.
Step 71: selected cell 22 is selected J induction module of corresponding maximum sense data, 0≤J≤M from the sense data of these induction modules 17.
Step 72: selected cell 22 judgement J＞C or J＜(M-C).If continue step 73; If not, flow process jumps to step 81, contains the situation of side induction module with otherwise processed above-mentioned reference induction module 17.
Step 73: as J＞C or J＜(M-C), selected cell 22 is chosen (J-C)～(J-1) individual induction module as the first evaluation group, and choose (J+1)～(J+C) individual induction module and be used as the second evaluation group.
For ease of narration, hereinafter the first evaluation group, the second evaluation group and J induction module are collectively referred to as " statistics group "
Step 74: whether the relativeness between the sense data of compensation deals unit 23 assessment statistics groups meets pre-conditioned.If be not inconsistent, rebound step 71 receives the next group sense data; If meet, continue execution in step 75.
Consult Fig. 6, the evaluation condition of this step has two: the first, and whether the sense data of the first evaluation group sequentially increases progressively with induction module sequence number; Whether the sense data of the second, the second evaluation group sequentially successively decreases with induction module sequence number.That is to say, when the sense data of statistics group internal induction module 17 spacing along with itself and J induction module widens and diminishes, just can execution in step 75.
This is that sense data can change as aforementioned condition because when on transverse axis, a plurality of adjacent induction modules 17 are pressed panel 1 and experienced pressure because of finger tip or pointer.If sense data does not meet aforementioned, be that unexpected interference behavior causes most probably, do not consider rebound step 71 crawl next group sense data so do not list in.
Step 75: each sense data of statistics group is inspected in compensation deals unit 23, if wherein a collection of sense data value is less than a sensing threshold, makes these data be adjusted into 0; If not, keep former data value.Because too small sense data may be to result from external environment to disturb, but not the touch control operation behavior, so this step is given up too small sense data.
Step 76: compensation deals unit 23 is each sense data S of statistics group
mDetermine that one adjusts multiplying power R
m
Consult Fig. 7, ideally, m induction module sense data S
mBe linearly related to detection-sensitive distance and present the triangle broken line as dotted line, but the in fact quafric curve painted of similar solid line.Such quafric curve can separate into and satisfy S
m＞2 (S
m-1+ S
m+1) the inelastic region, and do not satisfy the linear zone of this inequality.Go out to only have the linear zone performance near desirable triangle broken line by the figure observable, so this step wish to give linear zone the adjustment multiplying power R different with the inelastic region
m, with the difference of further actual sensed data and ideal value.Preferably, adjust multiplying power R
mIn satisfying S
m＞2 (S
m-1+ S
m+1) time have value 4/3, and have value 1 when not satisfying, but not as limit.
Step 77: arithmetic element 25 is used the sense data S of statistics group internal induction module 17 based on formula (1)
m, adjust multiplying power R
mWith place the first axle element x
m, calculate which coordinate on display surface 15 is clicked, then process ends.
Sense data S after adjusting
m' be to utilize to adjust multiplying power R
mAdjust sense data S
mResulting, this routine embodiment is S
m'=R
mS
mMoreover formula (1) also can be rewritten into formula (2), so another form also can be used the rear sense data S of induction module sequence number m, adjustment of statistics group
m' calculate with induction module spacing d to click coordinate.In addition, formula (1) also can be rewritten into formula (3), so can adjust with a displacement factor G first axle element J * d of J induction module, wherein G is based on statistics sequence number (m-J), adjusts rear sense data S
m' and induction module spacing d and resulting.
What specify is, compensation deals unit 23 is mainly to use to adjust multiplying power R
mAdjust each sense data S of statistics group
m, for example, the present embodiment uses larger adjustment multiplying power R
mCompensate the part that belongs to the inelastic region in the sense data distribution.But in other embodiments, sense data distributes can separate out more sections, and different section is to adjust multiplying power R with difference
mAdjust.Even, these adjust multiplying power R
mNeeding not be constant value, can be to be relevant to the sense data of sensing module 17 or the function of setting position.
So far, be more than that the induction module 17 of statistics group is not newspaper point methods performed when being positioned at side.If the close side in pressurized place of display surface 15 reports point methods to adjust as follows.
Step 81: as 0≤J≤C, the 0th～(J-1) individual induction module is chosen as the first evaluation group in boundary treatment unit 26, and chooses (J+1)～(J+C) individual induction module and be used as the second evaluation group; In addition, as (M-C)≤J≤M, choose (J-C)～(J-1) individual induction module and be used as the first evaluation group, and choose (J+1)～M induction module and be used as the second evaluation group.
Step 82: as 0≤J≤C, boundary treatment unit 26 makes the sense data of m=0 induction module be multiplied by a marginal multiplying power R
BAs M-C≤J≤M, boundary treatment unit 26 makes the sense data of m=M induction module be multiplied by this limit multiplying power R
B
Preferably, marginal multiplying power R
B=6/5, be used for the sensing function that compensation side induction module 17 reduces because part covered by deckle board 13.
Step 83: boundary treatment unit 26 judges whether to satisfy the sense data S of J=0 and the 1st～C induction module
1～S
CAll less than a critical value.If continue step 84; If not, jump to step 85.
Step 84: it is 0 * d that boundary treatment unit 26 reckonings click coordinate, and returns to step 71 and process the next group sense data.
Step 85: boundary treatment unit 26 judges whether to satisfy the sense data S of J=M and (M-C)～(M-1) individual induction module
M-C～S
M-1All less than this critical value.If, execution in step 86; If not, execution in step 74～77 is calculated based on one of them of formula (1)～(3) and is clicked coordinate.
Step 86: it is M * d that boundary treatment unit 26 reckonings click coordinate, and returns to step 71.
It should be noted that in another implements aspect, also can first execution in step 82～86, then execution in step 81 defines the first evaluation group and the second evaluation group.And step 83,85 can be carried out simultaneously, or the exchange execution sequence.
Also noteworthy is that, the present embodiment newspaper point methods also is applicable to the panel of multiple other types except being applicable to capacitance type touch-control panel, for example: and electric resistance touch-control panel, optical touch control panel, sound wave type contact panel, or the electromagnetic touch-control panel etc.
In the situation that mechanical arm slips over display surface 15 with the diagonally opposing corner mode straight line of bottom right, upper left, calculate that the resulting coordinate that clicks gathers together and can obtain Fig. 8 with prior art is linear, and the coordinate that clicks that the present embodiment is calculated is gathered together and can obtain Fig. 9.Two compare, and this routine result is pressed close to the diagonally opposing corner straight line of bottom right, upper left.
In addition, in the situation that mechanical arm slips over along display surface 15 right edge straight lines, calculate that the resulting coordinate that clicks gathers together and can obtain Figure 10 with prior art is linear, and the coordinate that clicks that the present embodiment is calculated is gathered together and can obtain Figure 11.Two compare, the obviously approximate straight line of this routine result.
Moreover, always measuring lower sense data if a certain induction module 17 sensing functions of panel 1 are on the weak side, arithmetic element 25 also can be at the front sense data that tunes up this induction module 17 according to a preposition multiplying power of step 70 so.Therefore, the sense data that arithmetic element 25 adjusts at last in step 77 has the effect of this preposition multiplying power at linear zone, has preposition multiplying power in the inelastic region and adjusts multiplying power R
mEffect.
For instance, mechanical arm with fixing power from left to right horizontal constant speed slip over display surface 15, can make adjacent two induction modules 17 within a period of time solid line and the dotted line of the sense data of sensing such as Figure 12, and then in conjunction with the solid line that goes out to click coordinate such as Figure 13.But under the prerequisite of fixing power, these two induction modules 17 should have similar sense data value ideally, thus the present embodiment especially for corresponding solid line and slightly weak that left side module 17 of sensing function with preposition multiplying power with adjust multiplying power R
mDraw high the pecked line of sense data value such as Figure 12, and then the pecked line that clicks coordinate such as Figure 13 after being compensated.Clearly, in Figure 13, the solid line coordinate before the compensation, the pecked line coordinate after compensation comparatively take back (i.e. correspondence less the first axle element).
In sum, in aforementioned preferred embodiment, newspaper point apparatus 20 can be in the inelastic region to adjust multiplying power R
mAdjust sense data, and can be with marginal multiplying power R
BAdjust the sense data of side induction module 17,18, thus can be clicked than which coordinate that prior art is oriented display surface 15 more accurately, so really can reach purpose of the present invention.
