Note that above-mentioned contact panel 200,510 can be a capacitance type touch-control panel, and the first touching signals S1 and the second touching signals S2 comprise capacitance change, but the present invention is not limited thereto, also can be the contact panel of other kinds.In addition, touch-control device 500 can be a mobile phone or a PDA(Personal Digital Assistant), but the present invention is not limited thereto, also can be the touch-control device of other kinds.
Please refer to Fig. 6, Fig. 6 is the synoptic diagram of an example of control circuit 540 among Fig. 5.In the present embodiment, control circuit 540 comprises one first judging unit 610, one second judging unit 620 and one the 3rd judging unit 630.First judging unit 610 is obtained one first coordinate (for example X1 ') of the first contact TU1 according to the first touching signals S1 at a numerical value VA11 of one first conductive pattern (for example 360,460), and obtains one first coordinate (for example X2 ') of the second contact TU2 at a numerical value VA21 of another first conductive pattern (for example 360,460) according to the second touching signals S2.Second judging unit 620 is obtained one second coordinate (for example Y1 ') of the first contact TU1 according to the first touching signals S1 at a numerical value VA12 of one second conductive pattern (for example 370,470) and at a numerical value VA13 of one the 3rd conductive pattern (for example 380,480), and according to the second touching signals S2 at the numerical value VA22 of another second conductive pattern (for example 370,470) and one second coordinate (for example Y2 ') of obtaining the second contact TU2 at a numerical value VA23 of another the 3rd conductive pattern (for example 380,480).In addition, second judging unit 620 according to above-mentioned numerical value VA12, VA13 produce be relevant to first the contact TU1 be a first information SI1 who keeps left or keep right, and according to above-mentioned numerical value VA22, VA23 produce be relevant to second the contact TU2 be the one second information SI2 that keeps left or keep right.At last, the 3rd judging unit 630 utilizes first information SI1 to decide the primary importance P1 of the first contact TU1 with the first coordinate X1 ', the second coordinate Y1 ' according to the first contact TU1 again, and utilizes the second information SI2 to decide the second place P2 of the second contact TU2 with the first coordinate X2 ', the second coordinate Y2 ' according to the second contact TU2.
Next, how the give an example control circuit 540 that describes touch-control device 500 in detail judges the position of multiplex touch control.At first, suppose that the primary importance P1 of the first contact TU1 drops on the coordinate of (X1 ', Y1 '), and the second place P2 of the second contact TU2 drops on the coordinate of (X2 ', Y2 ').
First judging unit 610 is obtained the first coordinate X1 ' of the first contact TU1 at the numerical value VA11 of one first conductive pattern according to the first touching signals S1, and according to the second touching signals S2 the numerical value VA21 of another first conductive pattern obtain second the contact TU2 the first coordinate X2 ', above-mentioned step can be represented by following formula:
X1’＝VA11 (1)
X2’＝VA21 (2)
Then, second judging unit 620 according to the first touching signals S1 at the numerical value VA12 of one second conductive pattern and the second coordinate Y1 ' that obtains the first contact TU1 at the numerical value VA13 of one the 3rd conductive pattern, and obtain the one second coordinate Y2 ' of the second contact TU2 at the numerical value VA22 of another second conductive pattern and at a numerical value VA23 of another the 3rd conductive pattern according to the second touching signals S2, above-mentioned step can be represented by following formula:
Y1’＝VA12+VA13 (3)
Y2’＝VA22+VA23 (4)
Thus, can obtain four possible coordinates (X1 ', Y1 '), (X1 ', Y2 '), (X2 ', Y1 ') and (X2 ', Y2 ').Transparency conducting layer 300 with Fig. 3 is an example, because second conductive pattern 370 on the same position and the area of the 3rd conductive pattern 380 are all different, also difference to some extent of the capacitance change that it produced then, this moment, second judging unit 620 can further judge that at the numerical value VA12 of one second conductive pattern and at the numerical value VA13 of one the 3rd conductive pattern the second coordinate Y1 ' of the first contact TU1 is keep left or keep right (that is first information SI1) according to the first touching signals S1.For example, as the result of VA12-VA13 during, judge the coordinate of Y1 ' near the left side greatly at one first critical value TH1; When the result of VA12-VA13 is little during at one second critical value TH2, judge the coordinate of Y1 ' near the right side; And when the result of VA12-VA13 is between the first critical value TH1 and the second critical value TH2, judge the coordinate of Y1 ' in the middle of being positioned at.
In like manner, second judging unit 620 can further judge that at the numerical value VA22 of another second conductive pattern and at the numerical value VA23 of another the 3rd conductive pattern the second coordinate Y2 ' of the second contact TU2 is keep left or keep right (that is second information SI2) according to the second touching signals S2.For example, as the result of VA22-VA23 during, judge the coordinate of Y2 ' near the left side greater than the first critical value TH1; As the result of VA22-VA23 during, judge the coordinate of Y2 ' near the right side less than the second critical value TH2; And when the result of VA22-VA23 is between the first critical value TH1 and the second critical value TH2, judge the coordinate of Y2 ' in the middle of being positioned at.
Note that the size of above-mentioned critical value TH1, TH2 and revocable, visual actual demand and practical application and adjust.Those skilled in the art should understand, and under spirit of the present invention, all are feasible about the various variations of the size of critical value TH1, TH2.
At last, the 3rd judging unit 630 just can utilize first information SI1 with according to first the contact TU1 the first coordinate X1 ', the second coordinate Y1 ' decide first the contact TU1 primary importance P1 be positioned at (X1 ', Y1 ') on, and utilize the second information SI2 to decide the second place P2 of the second contact TU2 to be positioned on (X2 ', Y2 ') with the first coordinate X2 ', the second coordinate Y2 ' according to the second contact TU2.
Above-mentioned example is an example with the transparency conducting layer 300 of Fig. 3, but only for being used for one of example that illustrates the technology of the present invention feature, those skilled in the art should understand, and this is not a restrictive condition of the present invention.
