In order to further illustrate touch control detection and the locator meams of the contact panel 101 of the present embodiment, please simultaneously referring again to Fig. 2 to Fig. 4.Figure 2 shows that the touch control detection mode schematic diagram of the contact panel of the present embodiment.Figure 3 shows that the touch control detection schematic diagram of the contact panel of the present embodiment under a multi-point touch situation.Figure 4 shows that the touch control detection schematic diagram of the contact panel of the present embodiment under an other multi-point touch situation.As shown in Figure 2, when touch control object such as finger presses first touch control unit 110 or the second touch control unit 120, the resistance variations of the first touch control unit 110 or the second touch control unit 120 that are positioned at touch-control center is by maximum, and from touch-control center more away from resistance variations will be less, the first axial electrode 110A corresponding to it or the resistance variations of the second axial electrode 120A before and after touch-control can be obtained further according to the difference of its resistance variations.
Further illustrate, the present embodiment supposes to put with three component levels to design different resistance variations, and the first touch control unit 110 wherein corresponding to touch-control center or the second touch control unit 120 may be defined as the first rank, and its resistance variations is Δ R1; The first touch control unit 110 close to secondary from touch-control central point or the second touch control unit 120 (also can say it is with the same row of touch-control central point or with the first touch control unit 110 or the second touch control unit 120 adjacent in a line) may be defined as second-order, and its resistance variations is Δ R2; And from the not same row of touch-control central point and the first touch control unit 110 adjacent in different a line or the second touch control unit 120 may be defined as the 3rd rank, its resistance variations is Δ R3.Δ R1 is greater than Δ R2 substantially, and Δ R2 is greater than Δ R3 substantially.Wherein, the present embodiment is only put with three component levels and is defined various level resistance variations, and the resistance variations beyond this three component level is put, the present embodiment is ignored to facilitate ensuing illustrating.Certainly, according to actual design demand, the resistance variations that also definable goes out more multistage position is done and is calculated judgement more accurately, at this not by the present invention is limited.
Next, suppose the top in Fig. 3 and Fig. 4 shownschematically direction be defined as the first row and leftmost is defined as first row.When the second touch control unit 120 that the secondary series and the 4th that touch points P1 as shown in Figure 3 and touch points P2 touches in same the third line respectively arranges, and touch points P3 as shown in Figure 4 and touch points P4 touch respectively the same 3rd arrange in the second row and the second touch control unit 120 of fourth line time, although maximum resistance change acquired under the touch condition of Fig. 3 and Fig. 4 be Δ R1 and three times of Δ R3 with and react by the second axial electrode 120A corresponding to first row fourth line and the 6th row, but the different location of carrying out multi-point touch of the resistance variations that the touch condition of Fig. 3 and Fig. 4 still produces by other first axial electrode 110A and/or the second axial electrode 120A, namely the resistance variations that the first axial electrode etc. such as corresponding to first row the third line produces has difference.
What remark additionally is, because the present embodiment is that the quick conductive material of employing power designs, therefore in the calculating of the resistance variations of above-mentioned each first axial electrode 110A and the second axial electrode 120A, if there is different touch points to form overlapping words in three defined rank position ranges, the first touch control unit 110 then corresponding to this overlapping or the resistance value of the second touch control unit 120 have to add takes advantage of effect, determine according to the electrical specification of side circuit, the present embodiment such as calculates with twice effect.Such as: namely touch points P1 and P2 is formed with the overlapping phenomenon of the resistance variations that the 3rd component level is put on the second touch control unit 120 of the 3rd row second row, therefore, when the resistance variations of the second axial electrode 120A belonging to calculating, namely the resistance variations of the second touch control unit 120 corresponding to this overlapping calculates with twice Δ R3.

Please refer to Fig. 8.Figure 8 shows that the schematic diagram of the contact panel of the third embodiment of the present invention.As shown in Figure 8, the present embodiment place different from above-mentioned second embodiment is, in the touch electrode structure 202S of the contact panel 202 of the present embodiment, the first touch control unit 110 is only arranged on odd column and the second touch control unit is only arranged on even column.By this, at least part of second touch control unit 120 being arranged in even column is electrically connected along bearing of trend D2 with at least one second touch control unit 120 of adjacent lines even column.The contact panel 202 of the present embodiment and touch electrode structure 202S are except the setting position of the first touch control unit 110 and the second touch control unit 120, the material behavior of all the other each parts, set-up mode and touch control detection mode be similar to above-mentioned second embodiment, therefore repeat no more at this.
The present invention also provides a kind of method for detecting of contact panel, is applicable to the position of touch detecting of the contact panel that the various embodiments described above provide.Only illustrate with the contact panel of embodiment corresponding to Fig. 1 below.Please refer to Fig. 9, Figure 9 shows that the method for detecting schematic diagram of the contact panel of a preferred embodiment of the present invention.As shown in Fig. 1 and Fig. 9, the method for detecting of the contact panel of the present embodiment comprises the following steps.First, carry out step S1, a contact panel 101 is provided.Wherein, the touch electrode structure 101S of contact panel 101 comprises multiple first touch control unit 110 and multiple second touch control unit 120.First touch control unit 110 and the second touch control unit 120 arrange in an array mode.Arrange with each second touch control unit 120 alternate intervals with each first touch control unit 110 in a line, be electrically connected to each other with the first touch control unit 110 in a line, to form multiple first axial electrode 110A, and the second at least part of touch control unit 120 be along a bearing of trend D1 be positioned at different rows and at least one second touch control unit 120 of different lines is electrically connected, to form multiple second axial electrode 120A.The feature of the contact panel 101 of the present embodiment describes in detail at foregoing, therefore repeats no more at this.
Then, carry out step S2, drive the first all axial electrode and the second axial electrode 120A simultaneously, and detect the output signal RS that the first axial electrode 110A and the second axial electrode 120A produces simultaneously.Then, carry out step S3, calculate position of touch coordinate according to those output signals RS.
From the explanation of earlier figures 3 and Fig. 4, because the present invention adjusts the electrical connection design of touch electrode structure, therefore each first touch control unit 110 on contact panel 101 or the second touch control unit 120 touched time, its all can correspond to unique one group of first axial electrode 110A and the second axial electrode 120A resistance variations combination.Calculate in embodiment in a detecting, by the resistance variations of the first axial electrode 110A and the second axial electrode 120A and the comparison of a tables of data, can obtain practical touch point is which touch control unit occurring in which axial electrode.In specific design, the resistance variations combination that analog quantity respectively measures the first corresponding axial electrode 110A and the second axial electrode 120A can be carried out in advance for touch-control inputs such as different position of touch and different touch-control states, and be stored as a tables of data, use the resistance variations combination allowing various touch-control input uniquely corresponding one group of first axial electrode 110A and the second axial electrode 120A.Thus, when actual generation touch-control, abovementioned steps S3 according in step S2 detect the output signal RS that obtains and to combine with the resistance variations in the tables of data preset and compare, the position of actual touch spots can be obtained.What deserves to be explained is, the present embodiment, in the comparison of the resistance variations representated by output signal RS, can be merely compare for all first axial electrode and the second axial electrode.In addition, also can be that first resistance variations representated by all output signal RS is to judge the specific region that touch points occurs, and only carry out comparison for the first axial electrode 110A corresponding to this specific region and the second axial electrode 120A, owing to not needing, for the first all axial electrode 110A and the second axial electrode 120A comparison one by one, can arithmetic speed to be accelerated.
It is adopt to leave out method to realize that another detecting calculates embodiment.In specific design, resistance variations size directly representated by output signal RS, descendingly reduce the contingent scope of touch points, with by face range shorter to point range, and then to obtain practical touch point be which touch control unit occurring in which axial electrode.In other words, first calculate the region of the first axial electrode 110A or the second axial electrode 120A contained lid on touch electrode structure producing maximum resistance change, calculate again afterwards and produce time the first axial electrode 110A of large resistance variations or the first axial electrode 110A of the second axial electrode 120A for aforementioned generation maximum resistance change or the relative position relation of the second axial electrode 120A, can not to first touch control unit 110 or second touch control unit 120 that touch points should be had to occur to screen and to reject in this region, by that analogy.Due to aforementioned carried each first touch control unit 110 on contact panel 101 of the present invention or the second touch control unit 120 touched time, it all can correspond to the resistance variations combination of unique one group of first axial electrode 110A and the second axial electrode 120A, therefore can leave out according to this position that method obtains practical touch point.Illustrate that this leaves out method with the resistance variations that the touch points shown in Fig. 3 and Fig. 4 produces.First, by the known generation maximum resistance change of Fig. 3 and Fig. 4 is the second axial electrode 120A that correspondence outputs signal that RS is Δ R1 and three times of Δ R3 sum, namely fourth line and the 6th row is positioned at and along the second axial electrode 120A in D1 direction, it can thus be appreciated that, touch points is positioned at fourth line and the 6th row and along on the second axial electrode 120A in D1 direction, and touch points may be only touch points P3 and touch points P4 shown in touch points P1 shown in Fig. 3 and touch points P2 or Fig. 4, so only need to get rid of one in these two kinds of situations and can determine touch points position.Afterwards, calculate time the first axial electrode 110A of large resistance variations or the second axial electrode 120A again, if secondary large resistance variations be positioned at the third line the first axial electrode 110A(as shown in Figure 3), then can determine that touch points is P1 and P2, namely touch points position is the third line secondary series and the third line the 4th row, if secondary large resistance variations be positioned at second and third and four lines the first axial electrode 110A(as shown in Figure 4), then can determine that touch points is P3 and P4, namely touch points lays respectively at the second row the 3rd row and fourth line the 3rd row.The present embodiment calculates embodiment compared to last detecting, does not need to prestore tables of data, does not also need flow process of comparing, and directly to screen the position that the mode rejected calculates touch points.
Comprehensive the above, contact panel of the present invention and touch electrode structure thereof are made up of the first touch control unit arranged in array way and the second touch control unit, and by the adjustment of electrical connection design, allow by same a line the first touch control unit the first axial electrode of being electrically connected with along a bearing of trend by different rows and the second touch control unit of different lines be configured with an angle being less than 90 degree between the second axial electrode of being electrically connected.Thus, can the first axial electrode and the second axial electrode be driven simultaneously and be scanned, and realize multi-point touch detection by calculating each axial electrode resistance variations corresponding before and after touch-control, and effectively improve the speed of touch-control reaction.
