Fig. 1 is according to the process flow diagram of the method for a kind of control capacitance formula touch screen terminal shown in an exemplary embodiment, and as shown in Figure 1, the method for control capacitance formula touch screen terminal is applied in terminal, comprises the following steps.
In step S101, judge whether current action is the action of clicking the TP of capacitive touch screens terminal.

The method that disclosure embodiment provides, by judging that current action is to click the action of TP, and judges that current action is the execution object of current action while clicking the action of the TP touch-down zone on TP.Therefore, in the time determining the region of implementing Grid Track filtering algorithm, can be directly select the filter field of suitable size to determine a contact coordinate by Grid Track filtering algorithm in the region of carrying out object and touch touch-down zone, not only definite contact coordinate is more accurate, and the scope of application is wider, and then can improve the precision of control capacitance formula touch screen terminal.
Fig. 2 is according to the process flow diagram of the method for a kind of control capacitance formula touch screen terminal shown in an exemplary embodiment, and as shown in Figure 2, the method for control capacitance formula touch screen terminal is applied in terminal, comprises the following steps.
In step S201, judge whether current action is the action of clicking the TP of capacitive touch screens terminal.
Wherein, about the execution object of current action, the embodiment of the present invention is not done concrete restriction, and while specifically enforcement, this execution object can be user's finger, can be also capacitance pen, etc.
Particularly, when user is by carrying out the action control capacitive touch screens terminal of object click TP, thereby while making capacitive touch screens terminal can carry out the operation corresponding with the action of carrying out object click TP, need to determine the contact coordinate of the action correspondence of carrying out object click TP.In actual applications, thereby the region of often by Grid Track filtering algorithm, user being touched TP by carrying out object is processed and is determined that execution object touches the contact coordinate of TP, and when object touches TP by clicking the action of TP, touch for carrying out the algorithm that the coordinate in the region of TP is processed because Grid Track filtering algorithm is generally to carrying out object, therefore, need to judge whether current action is the action of clicking the TP of capacitive touch screens terminal.
About judging whether current action is the mode of clicking the action of the TP of capacitive touch screens terminal, and disclosure embodiment does not do concrete restriction.When concrete enforcement, due in the time that user clicks the action control capacitive touch screens terminal of TP by carrying out object, touch TP from operation execution object to execution object and have a process, from operation carry out object to carry out object do not touch before TP during this period of time in, carry out object approach TP from drawing near directly over TP and be suspended in TP directly over.And in the time that user passes through to carry out the sliding action control capacitance formula touch screen terminal of object, the process that execution object touches TP is often for to slide to TP center from the lateral edges of TP.That is to say, carrying out the direction of carrying out object in object touches TP process by clicking the action of TP and the action of slip TP has obvious difference.Therefore, can touch the direction of carrying out object in TP process and judge whether current action is the action of clicking the TP of capacitive touch screens terminal by carrying out object.To sum up, judge whether current action is that the mode of clicking the action of the TP of capacitive touch screens terminal includes but not limited to: judge whether current action is directly over TP, to draw near to approach the action of TP; If current action is to draw near to approach the action of TP, judge that current action is the action of clicking the TP of capacitive touch screens terminal directly over TP.
Wherein, judge that whether current action is the mode of the action that approaches TP that draws near, and can have a variety of directly over TP.When concrete enforcement, include but not limited to realize by following two kinds of modes:
First kind of way: be generally a conductor owing to carrying out object, therefore, execution object draws near and approaches the process of TP directly over TP, can produce certain influence to the electric capacity on TP.For example, if to carry out object be user finger, the process that finger touches TP will make the self-capacitance on TP increase or mutual capacitance reduces.And in the process of the capacitance variations on TP, it is upper that a part of electric capacity will be transferred to finger, and the built-in touch-control chip of TP can detect the situation of change of finger capacitance signal.Therefore, judging that whether current action is to draw near while approaching the action of TP directly over TP, can detect the capacitance signal variable quantity of carrying out object in the unit interval, and judge according to the capacitance signal variable quantity of this execution object whether current action is directly over TP, to draw near to approach the action of TP.
About judging that according to carrying out the capacitance signal variable quantity of object whether current action is the mode of the action that approaches TP that draws near directly over TP, disclosure embodiment does not do concrete restriction.When concrete enforcement, can determine that carrying out object approach the speed of TP by carrying out the capacitance signal variable quantity of object in the unit interval, and further judge according to the speed of carrying out object and approach TP whether current action is directly over TP, to draw near to approach the action of TP.For example, when carrying out object for when finger, finger touches TP process by clicking the action of TP is the process of a freely falling body, and therefore, finger and TP are in the time of different distance, and the speed that finger approaches TP is also different.Therefore, can judge whether finger movement is directly over TP, to draw near to approach the action of TP whether reaching predetermined threshold value with TP digit speed when the predeterminable range according to finger.Certainly, herein only to judge finger illustrates judge whether current action approaches TP action as drawing near directly over TP according to the capacitance signal variable quantity of carrying out object whether reaching predetermined threshold value with TP digit speed when the predeterminable range.When concrete enforcement, can also adopt alternate manner to judge according to the capacitance signal variable quantity of carrying out object whether current action is directly over TP, to draw near to approach the action of TP, and disclosure embodiment does not do concrete restriction to this.
The second way: due in the time that execution object touches TP by clicking the action of TP, with TP when the different distance, the capacitance signal of the execution object that touch-control chip detection arrives is often also different, therefore, can carry out the capacitance signal that object and TP carry out object when the predeterminable range by detection and whether reach predetermined threshold value, and judge according to carrying out object and the TP testing result that whether capacitance signal when predeterminable range reaches predetermined threshold value apart whether current action is directly over TP, to draw near to approach the action of TP.Wherein, due in the time touching TP by the click action of TP and the action of slip TP, not identical in the value of capacitance signal of carrying out object with TP when the predeterminable range yet, therefore, predetermined threshold value be herein when current action be while clicking the action of TP, to carry out object and the TP value of corresponding capacitance signal when predeterminable range apart.
Concrete, if execution object and the TP capacitance signal in the time of predeterminable range reaches predetermined threshold value, judge that current action is directly over TP, to draw near to approach the action of TP; Do not reach predetermined threshold value if carry out object and the TP capacitance signal in the time of predeterminable range, judge that current action for not drawing near and approach the action of TP directly over TP.
In addition, disclosure embodiment not to carry out predeterminable range apart of object and TP and carry out object and TP apart the size of the predetermined threshold value of capacitance signal when predeterminable range limit.When concrete enforcement, can rule of thumb arrange and carry out predeterminable range apart of object and TP and carry out object and the TP size of the predetermined threshold value of capacitance signal when predeterminable range apart.
In step S202, if current action is to click the action of TP, the touch-down zone of the execution object that judges current action on TP, wherein, touch-down zone is to carry out while being suspended in directly over TP in the process that object approaches TP region corresponding on TP.
Wherein, because touch-down zone is to approach while being suspended in directly over TP in the process of TP region corresponding on TP when carrying out object, therefore, touch-down zone is to carry out the region that may touch on TP when object is carried out the action of clicking TP.
Judging that current action is to click after the action of TP, in order to determine the action of carrying out object and can or can not sport in the action of the click TP that approaches TP of drawing near slip TP directly over TP, the touch-down zone of the execution object that can also further judge current action on TP.Particularly, judging behind touch-down zone, because touch-down zone is to carry out the region that may touch on TP when object is carried out the action of clicking TP.Therefore,, in the time that execution object touches touch-down zone, can determine that current action is the action of clicking TP; And judging behind touch-down zone, just started as drawing near and approach the action of TP directly over TP if there is carrying out object, but while becoming sliding action suddenly, carry out object touch the region of TP may be not in touch-down zone, now, can determine that current action is not for clicking the action of TP.
The mode in the touch-down zone about the execution object that judges current action on TP, disclosure embodiment does not do concrete restriction.When concrete enforcement, owing to being while clicking the action of TP when current action, carry out object draws near and will have the process being suspended in directly over TP approaching process directly over TP, again because the built-in sensor matrices of TP has laterally longitudinal two kinds of arrangement modes, and each sensor only can be identified the capacitance signal of the execution object directly over its passage.Therefore, can be by the touch-down zone of the execution object of carrying out the current action of region decision that the sensor of capacitance signal of object is corresponding on TP being detected.For example, if carry out object for finger, and the built-in sensor matrices of TP is 10*10, if touched in the process of TP by the action of clicking TP at finger, second sensor of transversely arranged second sensor and longitudinal arrangement detects respectively finger capacitance signal, can determine that finger will touch the region at these two sensor places, therefore, can be using the region at these two sensor places as the touch-down zone of pointing on TP.
Alternatively, judge behind the touch-down zone of finger on TP at the capacitance signal of carrying out object by detection, can in touch-down zone, touch TP by the action of clicking TP in order to ensure carrying out object, can suitably expand the size in touch-down zone.For example, if detect that the area size at sensor place of finger capacitance signal is 50*50 pixel, at judgement finger when the touch-down zone on TP, can this 50*50 pixel centered by, by the expanded in size in touch-down zone to 70*70 pixel.
In step S203, touch the region in touch-down zone at execution object and determine a contact coordinate by Grid Track filtering algorithm.
While touching TP due to execution object by clicking the action of TP, touch-control chip often can detect that carrying out object occurs slight mobile, and in the time that execution object slightly moves, can on TP, form a contact track, thereby make touch-control chip be resolved to multiple contact coordinates.In actual applications, often corresponding different operation of the different contact coordinate on TP.Owing to having determined that by step S201 and step S202 current action is the action of clicking TP, and in the time of the action control capacitive touch screens terminal by clicking TP, making coordinate by a contact just can control capacitance formula touch screen terminal.Therefore,, in the time determining contact coordinate by Grid Track filtering algorithm, determine a contact coordinate.Therefore, in order to ensure that user is when clicking the action control capacitive touch screens terminal of TP, capacitive touch screens terminal can be carried out the operation that user expects, need to determine a contact coordinate by Grid Track filtering algorithm in the region of carrying out object and touch touch-down zone.
Determine a contact coordinate by the region of touching touch-down zone at execution object by Grid Track filtering algorithm, can guarantee that the contact coordinate that touch-control chip reports to processor only has one, therefore, guarantee that processor can be in a subsequent control execution unique operation corresponding to contact coordinate definite with this.
The mode of determining a contact coordinate about the region of touching touch-down zone at execution object by Grid Track filtering algorithm, disclosure embodiment does not do concrete restriction.When concrete enforcement, include but not limited to, by Grid Track filtering algorithm, the central point of carrying out object and touching in the default size area in touch-down zone is defined as to contact coordinate.Particularly, can touch by Grid Track filtering algorithm the default size area of TP processes carrying out object, determine and carry out contact that object touches TP whether all the time in this default size area, if carry out contact that object touches TP all the time in this default size area, the central point of carrying out object and touching in the default size area in touch-down zone is defined as to contact coordinate.
Wherein, disclosure embodiment does not limit the concrete size of default size area.When concrete enforcement, due to the TP for different TP specifications and different TP resolution, touch the region in touch-down zone for execution object, the number of its contact coordinate that can identify is also often different.Therefore, this default size area can be determined in conjunction with the resolution situation of TP specification and display screen.In addition, if carry out object for finger, this default size area also can be selected according to finger thickness the region of suitable size.Alternatively, in order to ensure that the process that the thicker user of finger clicks the action control capacitive touch screens terminal of TP by finger can successfully realize, and can arrange larger default size area.For example, if conventionally determine contact coordinate by Grid Track filtering algorithm in finger touches the filter field of pixel of the 30*30 of TP in correlation technique, in disclosure embodiment, can in touching the pixel region of 50*50 in touch-down zone, finger determine contact coordinate by Grid Track filtering algorithm.By the default size area of flexible selection, make to determine that by Grid Track filtering algorithm the mode of contact coordinate has more dirigibility.
In step S204, control capacitance formula touch screen terminal is carried out the operation corresponding with contact coordinate.
Due to when the control capacitance formula touch screen terminal, the different contact coordinate on TP is corresponding different operation often.Touch TP and realize the operation of control capacitance formula touch screen terminal in order to meet user by clicking the action of TP, determining after a contact coordinate by Grid Track filtering algorithm, need control capacitance formula touch screen terminal to carry out the operation corresponding with contact coordinate.The mode of carrying out the operation corresponding with contact coordinate about control capacitance formula touch screen terminal, disclosure embodiment does not do concrete restriction.When concrete enforcement, can be first from the mapping relations of pre-stored contact coordinate and operation, inquire about the operation that definite contact coordinate is corresponding, and control the control capacitance formula touch screen terminal execution operation corresponding with the contact coordinate inquiring.
The method that disclosure embodiment provides, by judging that current action is to click the action of TP, and judges that current action is the execution object of current action while clicking the action of the TP touch-down zone on TP.Therefore, in the time determining the region of implementing Grid Track filtering algorithm, can be directly select the filter field of suitable size to determine a contact coordinate by Grid Track filtering algorithm in the region of carrying out object and touch touch-down zone, not only definite contact coordinate is more accurate, and the scope of application is wider, and then can improve the precision of control capacitance formula touch screen terminal.
