Refer to Fig. 4, Fig. 4 is the implementation method of a kind of novel combination type touch unit of the present invention, and as shown in the figure, it comprises step:
The mode that S101, employing are combined passage, utilizes the multiplexing of several passages, is combined as different touch unit;
S102, mobile terminal touch screen is carried out to subregion processing obtain some subregions, the touch unit in each subregion adopts the mark of one or more special modality as subregion, and the mark of each subregion is different;
S103, in the time detecting that subregion has touch-responsive, calculate the relative position of touch point in touch unit according to the response of different passages in touch unit, then draw the coordinate of touch point on touch-screen according to the relative position of each touch unit.
In step S101, the touch unit of the embodiment of the present invention is that individual layer is from holding structure, adopt the mode of combination to form new touch unit, if for example there are 6 passages, adopting 4 combination of channels is wherein a touch unit, by different combinations, can form 15 kinds of different touch unit, using 15 kinds of different touch unit as the identification touching, can greatly reduce the port number of IC, realize 15 touch unit by 6 passages, compared with this design that realizes 6 touch unit with 6 traditional passages, there is hardware design simple, port number is few, the advantage that cost is reduced.
Certainly, combinations thereof mode only, for for example, can also be got 3 combination of channels and become a touch unit, thereby be combined into 20 kinds of touch unit from 6 passages, or from more passage, takes out some combination of channels and become touch unit.
Become 15 touch unit to make an explanation as example to take out 4 combination of channels from 6 passages below.
6 passages are named according to 1,2,3,4,5,6 respectively, each touch unit has 4 passages, its array mode is: 1234,1235,1236,1245,1246,1256,1345,1346,1356,1456,2345,2346,2356,2456,3456 totally 15 kinds, as shown in Figure 5, it is the structural representation of one of them touch unit, these 15 touch unit are arranged on the screen body of mobile terminal touch screen, each dashed rectangle represents a touch unit, as described in Figure 6, just can form a complete touch-screen.
Certainly, combinations thereof mode is only for giving an example, can also from 6 passages, get 3 combination of channels and become a touch unit, thereby be combined into 20 kinds of touch unit, or from more passage, take out some combination of channels and become touch unit, as shown in Fig. 7 to Figure 13, it represents the structural representation of different touch unit, 9 touch unit that passage forms are comprised, 16 touch unit that passage forms, 6 touch unit that passage forms, 2 touch unit that passage forms, 3 touch unit that passage forms, its structure also can convert adjustment according to existing touch unit version.

Simultaneously, in embodiments of the present invention, each passage in each touch unit, the passage being adjacent is different, thereby avoid leaning on to obtain between adjacent cells the closer problem that causes erroneous judgement, be adjacent because the each passage in each touch unit has 8 passages, become different touch unit so preferably can choose some combination of channels from more than 9 passages, as shown in figure 15.
Certainly, also the passage that can only require the four direction up and down of the each passage in touch unit can not repeat, and the passage of oblique angle direction can be identical, as shown in figure 16, due to the passage apart from each other of oblique angle direction, it also can to a certain degree avoid the problem of erroneous judgement.
In step S103, need to calculate the coordinate of touch location on touch-screen according to the touch-responsive of subregion, as shown in figure 17, it specifically comprises the steps:
S201, beginning;
S202, in the time detecting that subregion has touch-responsive, judge whether this touch-responsive is single region response, proceeds to step S203 in the time being, detect otherwise return again;
Owing to being provided with the mark of special modality as subregion in each subregion, thus in the time that certain special modality has response, can find the subregion that has touch-responsive, and determine whether the response in single region.
The embodiment of the present invention is for simplified design, and the situation that is only single region for single-point touches is analyzed, and for the situation of many finger operations, its implementation procedure and algorithm are more complicated, but ultimate principle is identical.
S203, judgement have in the touch unit of touch-responsive, and whether all passages have response, in the time being, proceed to step S204, rejudge otherwise return;
In the touch unit that has touch-responsive, only have all passages to have response, just can think that this touch unit has been triggered.
S204, calculate the relative position of touch point in this touch unit according to the response of different passages in touch unit;
Different passages have different responses, can calculate the relative position of touch point in touch unit according to response difference.
S205, relative position and this touch unit according to touch point in this touch unit calculate the coordinate of touch point on mobile terminal touch screen at the relative position of mobile terminal touch screen.
According to touch unit the relative position of whole mobile terminal touch screen and before calculate the relative position of touch point in touch unit, just can calculate the coordinate of touch point on mobile terminal touch screen, thus in this coordinate response user's touch operation.
