Description
[technical field]
The present invention refers to a kind of method that produces a touch-control coordinate of touch-sensitive display especially about touch-sensitive display.
[background technology]
Touch-sensitive display is because it can provide more intuitive and better human-computer interaction effect, therefore, be used in various fields widely, and comply with the difference of its sensing principle, it is dissimilar to include resistance-type, condenser type, infrared-type and acoustic wave etc. in the middle of the touch control display again.Wherein, the sensing mode of existing capacitance touching control display please refer to Fig. 1 and the following description.As shown in the figure, touch-sensitive display 100 includes the sensing array that a plurality of sensing component SA1～SA8 and SB1～SB14 are formed, the sensing array mainly comprises the staggered sensing electrode of diamond shaped (diamond shape) and (please notes, do not draw whole sensing electrodes in the diagram), each sensing component can come definable to go out the coordinate of certain limit by the sensing electrode of diamond shaped, for instance, if on the X-axis 480 coordinate points are arranged, then the interval definable of the coordinate of sensing component SA2 goes out coordinate figure 60～120.When the position P of user's touch-control on the display surface 110 of display 100, this moment, sensing component SA6 will produce certain sensing value because of user's the touch-control incident that touching caused.In general, although the touch-control incident that the user caused causes sensing component SA6 to produce a tangible sensing value, but the touch-control incident often also can cause sensing component SA5 and SA7 to produce a certain size sensing value, and when calculating the actual sensed coordinate, sensing value and its coordinate reference value of representing respectively that sensing component SA5～SA7 can be produced are weighted average calculating operation, in the hope of the sensing coordinate.Wherein, a kind of habitual average weighted expression formula please refer to as follows:
(VA5*LA5+VA6*LA6+VA7*LA7)/(LA5+LA6+LA7)
In the middle of, VA5～VA7 is respectively the sensing value of sensing component SA5～SA7, and LA5～LA7 then represents the coordinate reference value of sensing component SA5～SA7.
Above coordinate Calculation mode can draw the pairing sensing coordinate of touch-control incident.Yet, because the relation of present position, sensing component SA1 and SA8 can can't define the coordinate figure of certain part, even if cause user's touch-control some zone on the display surface 110 of display 100, but still can't produce corresponding to those regional coordinate figures, cause so-called border area (edge zone) phenomenon to take place, it is the zone that indicates with oblique line on the display surface 110.Cause the reason in border area to be attributable to the sensing Coordinate Calculation and must be weighted average gained with reference to the sensing value and the coordinate reference value of adjacent sensing cell, yet, concerning sensing component SA1, because there is not any sensing component in its left side, so the result of weighted mean computing will can't produce the coordinate figure (as: 1～30) in left side forever, so that sensing component SA1 can't define coordinate figure 1～30.Same, this phenomenon also can occur on sensing component SA8, the SB1 and SB14 at the edge that is positioned at display 100.Such phenomenon can cause the inconvenience of touch control display 100 on practice.For instance, if the touch-control incident betides in the border area,, cause application program can't correctly pick out the actual position of touch-control incident because sensing component can't reflect the coordinate of touch-control incident.As from the foregoing, prior art still has problem demanding prompt solution.
[summary of the invention]
In view of this, the object of the present invention is to provide a kind of method to solve border area problem in the touch-sensitive display.Wherein, the mode by the coordinate Mapping conversion defines the coordinate figure that is positioned at the border area originally.For example, will be corresponding to certain coordinate figure of coordinate figure reflection to the border area in zone partly, thus, the sensing array goes out coordinate figures all on the touch-sensitive display with definable.
One embodiment of the invention provide a kind of method of generation one touch-control coordinate, and this method comprises: utilize a sensing array that includes many sensing components to come sensing one touch-control incident pairing one initial sensing coordinate; Judge whether this initial sensing coordinate falls within a coordinate and adjust interval; When this initial sensing coordinate falls within this coordinate adjustment interval, produce this touch-control coordinate of this touch-control incident according to a transfer function and this initial sensing coordinate; And when this initial sensing coordinate does not fall within this coordinate adjustment interval, be used as this touch-control coordinate of this touch-control incident with this initial sensing coordinate.
Another embodiment of the present invention provides a kind of method of generation one touch-control coordinate, and this method comprises: utilize a sensing array that includes many sensing components to come sensing one touch-control incident pairing one initial sensing coordinate; Defining a coordinate according to a coordinate interval that is positioned at a sensing component at this sensing array edge adjusts interval; Judge whether this initial sensing coordinate falls within a coordinate and adjust interval; When this initial sensing coordinate falls within this coordinate adjustment interval, produce this touch-control coordinate of this touch-control incident according to a transfer function and this initial sensing coordinate; And when this initial sensing coordinate does not fall within this coordinate adjustment interval, be used as this touch-control coordinate of this touch-control incident with this initial sensing coordinate.

[embodiment]
In the following interior literary composition, to and graphicly set forth notion of the present invention with several embodiment, wherein, too abstract for fear of the content of explaining, the explanation of embodiment will be mentioned optional network specific digit, yet, because of being when what note, these optional network specific digits only one of may be implemented in the aspect for the present invention is many, but not restriction of the present invention.The people who has the knack of technology neck under the present invention is when can be behind this instructions of intensive reading, learn as other possible numeral how and realize the present invention, and the variation in this design should belong to category of the present invention.In addition, on behalf of it, the present invention's assembly of having same numeral in difference is graphic similar principle of operation and technology effect are arranged.So, below in literary composition will omit repeatability narration.Moreover mentioned different technologies feature among the different embodiment is not limited to this embodiment in the literary composition.In fact, in reasonable category of the present invention, can be by suitable modification, so that it possesses the peculiar technical characterictic of other embodiment to certain embodiment.
Please refer to Fig. 2, the principle of its diagrammatic illustration the inventive method.As shown in the figure, coordinate figure 1～30 falls within the border area, left side (oblique line district) of the sensing array 210 of touch control display 200, for allowing the sensing electrode in the sensing array 210 be defined these coordinate figures, the coordinate figure 30～90 that the inventive method will be close to the place maps to coordinate figure 1～90.Change speech, when average weighted result points out that a sensing coordinate CA of touch-control incident is one in the coordinate figure 30～90, can sensing coordinate CA be mapped as one in the coordinate figure 1～90, for instance by a transfer function, if the coordinate figure of sensing coordinate CA is 30, by transfer function, will video to coordinate figure is 1 touch-control coordinate CA ', and if the coordinate figure of coordinate CA is 90, by transfer function, will video to coordinate is 90 touch-control coordinate CA '.And central coordinate figure will have 1.5 times multiplying power relation, and this is because only there are 60 unit lengths (30～90) in coordinate interval to be videoed originally, and the coordinate interval (1～90) of 90 unit lengths of in fact must videoing out.Therefore must concern with 1.5 times multiplying power and shine upon.Same, be border area, the right side problem of the sensing component SC8 on the right side that solves sensing array 210.When the coordinate figure of sensing coordinate CA is 390, by transfer function, will video to coordinate figure is 390 touch-control coordinate CA ', and if the coordinate figure of sensing coordinate CA is 450, and by transfer function, will video to coordinate is 480 touch-control coordinate CA '.Should be noted that, along with the size of touch control display is different with the Density Distribution of sensing component, the coordinate burst length that each sensing component can define all can be different with the coordinate burst length that can't define, so mentioned number should not be considered as restriction of the present invention in the above explanation.
Based on above explanation, the inventive method can further reduce broad sense flow process shown in Figure 3.Wherein, include step:
Step 310: utilize the sensing array 210 that includes a plurality of sensing component SC1～SC8 to come sensing one touch-control incident pairing one initial sensing coordinate CA;
Step 320: judge whether initial sensing coordinate CA falls within a coordinate and adjust interval ACP;
Step 330: when initial sensing coordinate CA falls within coordinate and adjusts interval ACP, produce the touch-control coordinate CA ' of this touch-control incident according to a transfer function F and initial sensing coordinate CA;
And
Step 340: when initial sensing coordinate CA does not fall within coordinate and adjusts interval ACP, be used as the touch-control coordinate CA ' of this touch-control incident with initial sensing coordinate CA.
At first, in step 310, the sensing value that can be produced according to sensing array 210 is weighted average calculating operation, to produce initial sensing coordinate CA.Then, in step 320, can judge whether that the coordinate whether initial sensing coordinate CA falls within both sides adjusts among one of interval ACP.And, when initial sensing coordinate CA falls within coordinate and adjusts interval ACP, produce the touch-control coordinate CA ' of this touch-control incident according to a transfer function F and initial sensing coordinate CA.In the middle of, if initial sensing coordinate CA falls within the coordinate in graphic left side when adjusting interval ACP, then transfer function F is (X-a) * b+1, and X is the coordinate figure of initial sensing coordinate CA, a is the lower boundary between coordinate adjustment district, left side ACP, and b is that coordinate is adjusted the burst length multiplying power (as: 90/60) between interval ACP and the interval CP of coordinate.Wherein, the interval CP of coordinate represents 210 border areas that can't define of sensing array, respectively has one in the left side and the right side of sensing array 210.Moreover, if initial sensing coordinate CA falls within the coordinate on graphic right side when adjusting interval ACP, then transfer function F is a+ (X-a) * b, and X is the coordinate figure of initial sensing coordinate CA, a is the lower boundary between coordinate adjustment district, right side ACP, and b is that coordinate is adjusted the burst length multiplying power (as: 90/60) between interval ACP and the interval CP of coordinate.In addition, when initial sensing coordinate CA does not fall within coordinate and adjusts interval ACP, come directly touch-control coordinate CA ' with initial sensing coordinate CA, and do not need any conversion as this touch-control incident.Thus, by the reflection of transfer function, can make sensing array 210 define the coordinate figure that is in the border area originally smoothly.
In addition, in one embodiment of the invention, include again: define coordinate according to the interval CP of the coordinate of a sensing component (sensing component SC1 or SC8) that is positioned at sensing array 210 edges and adjust step between interval ACP.For instance, when the interval CP of coordinate was 1～30, then the present invention may be defined as 30～90 with the interval ACP of coordinate adjustment, or was defined as 30～100 and waits other to be adjacent to the coordinate interval of the interval CP of coordinate.
It should be noted; the actual application of the present invention may run into following problem; please refer to Fig. 4 special sensing component SC1 and the SC2 that indicates; because sensing component can be disturbed by noise usually; even if the touch-control incident K that therefore user caused does not touch the sensing range of sensing component SC2 fully; but still may produce a certain size sensing value because of disturbing factors such as noise cause sensing component SC2; thus, may cause average weighted result and fail to pick out really the pairing sensing coordinate of touch-control incident.For instance, as shown in Figure 4, if the user touches the sensing range X of sensing component SC1 fully and does not touch the sensing range Y of sensing component SC2, then sensing component SC2 should be unable to produce any sensing value in theory, and the coordinate figure of the pairing sensing coordinate of this touch-control incident should be the coordinate reference value 30 of sensing component SC1, yet, because sensing component SC2 has produced sensing value because of disturbing factors such as noises, the actual coordinate value that the possibility of result of historical facts or anecdotes border weighted mean computing can cause the pairing sensing coordinate of this touch-control incident greater than 30 (that is, the sensing coordinate can be offset between the coordinate reference value 90 of the coordinate reference value 30 of sensing component SC1 and sensing component SC2), form so-called skew (offset), since this bias effect the coordinate figure of sensing coordinate, so also can influence to some extent to the decision in coordinate adjustment of the present invention interval.
Therefore, in one embodiment of the invention, coordinate adjustment interval define the consideration that step has added migration parameter.In the middle of, the calculating of migration parameter 0st is the length (as: 0～30 → 30) according to the interval CP of coordinate, the one first sensed quantity A that the sensing component (as: SC1 or SC8) at edge is caused during by complete touch-control and another sensing component (as: SC2 or SC7) that is close to this sensing component be not by touch-control but this sensing component (SC1 or SC8) pairing one second sensed quantity B during by touch-control (preferably, the maximum sensing value that the second sensed quantity B may be produced in not by touch-control the time for this another sensing component) decides migration parameter 0st.This migration parameter can be decided based on following formula:
(B/(A+B))*z
Relation about sensed quantity A, B and numerical value z can be with reference to the explanation of figure 5.Wherein A is sensing component SC1 during by complete touch-control, the sensed quantity that sensing component SC1 is produced, and B for next-door neighbour's sensing component SC2 not by touch-control, but sensing component SC1 is during by touch-control, the sensed quantity B that sensing component SC2 is produced.Moreover numerical value z then is the sensing component coordinate length of an interval degree that institute can't define in the border area (as the pairing length 30 of, coordinate interval CP).
Based on the migration parameter 0st of above-mentioned gained, can adjust the lower bound of interval ACP in order to define coordinate, in other words, include the lower bound of the interval ACP of coordinate adjustment of migration parameter consideration in and must add 0st (as: 30+0st or 390-0st).Moreover coordinate is adjusted the upper bound of interval ACP and then must be decided with the account form of another kind of migration parameter 0st ':
[(B/(A+B))*z+1]*b
Wherein b is that interval CP of coordinate and coordinate are adjusted the burst length multiplying power between the interval ACP, that is, 90/60=1.5.And, can adjust the upper bound addition of interval ACP with coordinate originally based on the migration parameter 0st ' that this formula determined, that is, 90+0st ' or 450-0st '.
Only explain notion of the present invention with the coordinate of single dimension although should be noted in the discussion above that above explanation, in fact, coordinate conversion of the present invention can be in a coordinate more than the dimension.For example, initial sensing coordinate CA may be corresponding to an X-axis coordinate or a Y-axis coordinate.
In addition, another embodiment of the present invention also provides a kind of method of generation one touch-control coordinate, and this embodiment can further reduce broad sense flow process shown in Figure 6.Wherein this flow process includes step:
Step 610: utilize a sensing array that includes many sensing components to come sensing one touch-control incident pairing one initial sensing coordinate;
Step 620: define a coordinate according to a coordinate interval that is positioned at a sensing component at this sensing array edge and adjust interval;
Step 630: judge whether this initial sensing coordinate falls within a coordinate and adjust interval;
Step 640: when this initial sensing coordinate falls within this coordinate adjustment interval, produce this touch-control coordinate of this touch-control incident according to a transfer function and this initial sensing coordinate; And
Step 650: when this initial sensing coordinate does not fall within this coordinate adjustment interval, be used as this touch-control coordinate of this touch-control incident with this initial sensing coordinate.
Compared to the embodiment of Fig. 3 representative, the embodiment of Fig. 6 has added the step that defines coordinate adjustment interval.In addition, this embodiment also can improve the problem that prior art can't define the coordinate figure in the border area.
Method of the present invention can specifically be implemented according to following mode, as: by processor carry out a software, by pure hardware circuit, or both combinations.Processor may be general usefulness or application specific processor, and this software comprises the programmable logic, and instruction and data can realize the effect that the inventive method has when being performed.Wherein, this software can be stored in the computer-readable media, as ROM (read-only memory), and random access memory, disc driver, CD-ROM drive, flash memory or any other possible digital storage medium.Moreover method effect of the present invention also can realize by the pure hardware circuit that includes the online logic of hardware (hard-wired logic).
In sum, the inventive method is utilized the notion of coordinate Mapping conversion, efficiently solves the problem that the border area internal coordinate value of touch-sensitive display in the prior art can't be defined, and then has promoted the utilization effect of touch-sensitive display.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
