Embodiment
For exist in prior art by arranging special sensor and avoiding the error touch control of capacitance touch screen time, the design cost caused and design difficulty increase, the size of limiting capacitance touch-screen and layout, and sensing range cannot cover the problem of whole touch-screen scope, the embodiment of the present invention provides a kind of method preventing mobile terminal touch screen error touch control, as shown in Figure 1, concrete execution step is as follows for the flow process of the method:
S10: start.
S11: when the touch-screen of mobile terminal be in can touch-control state time, the detection signal strength that monitoring touch-screen exports.
In use, can be in can touch-control state for existing mobile terminal touch screen, such as: voice call, browse webpage etc., at this moment can come to operate accordingly by touch-control touch-screen.Can touch-control state as long as touch-screen is in, just need the detection signal strength that monitoring exports from touch-screen.Can monitor according to the time cycle of setting, also can set the time of monitoring as required.
S12: according to the detection signal strength monitored and the relation setting threshold value, determine whether touch-screen error touch control occurs, when result is for being, performs S13; When result is no, perform S11.
S13: Do not touch screen response touch-control.
When generally normal touch control operation being carried out to touch-screen, touch point number only has a few, when the position such as face, arm of people will touch unintentionally touch-screen or touch touch-screen, this just there occurs error touch control, because this is not the touch-control made to realize certain operation, at this moment touch point number can be many.Just can determine whether touch-screen error touch control occurs according to the detection signal strength monitored and setting threshold value, once determine to there occurs error touch control, Do not touch screen response touch-control at once, but still can monitor the detection signal strength of touch-screen output.
Concrete, the detection signal strength that the monitoring touch-screen in above-mentioned S11 exports, according to the number difference of the electrode that touch-screen has, the detection signal strength that touch-screen exports is not identical yet, can comprise following several situation:
The first, when touch-screen has an electrode, the strength of current flowed out according to this electrode of the time cycle monitoring touch-screen of setting, using the detection signal strength that the strength of current monitored exports as touch-screen.
Existing capacitance touch screen is provided with electrode, and when human body proximity touch-screen or touch-control are to touch-screen, human body, as another electrode, forms coupling capacitance with touch-screen, now has electric current and flows out from the electrode of touch-screen.When touch-screen has an electrode, the strength of current that can flow out according to the electrode of the time cycle monitoring touch-screen of setting, using the detection signal strength that the strength of current monitored exports as touch-screen.Can according to the actual needs setting-up time cycle, if when needing accurately to monitor touch-screen, what the time cycle can be arranged is shorter; If when not needing accurately to monitor touch-screen, what the time cycle can be arranged is longer.
The second, when touch-screen has at least two electrodes, monitors respectively from the strength of current that at least two electrodes of touch-screen flow out, using the detection signal strength that the average of at least two strength of current monitored exports as touch-screen according to the time cycle of setting.
When touch-screen has at least two electrodes, using the detection signal strength that the average of each strength of current monitored exports as touch-screen.Can according to the actual needs setting-up time cycle, if when needing accurately to monitor touch-screen, what the time cycle can be arranged is shorter; If when not needing accurately to monitor touch-screen, what the time cycle can be arranged is longer.
The third, when touch-screen has at least two electrodes, according to the time cycle monitoring of setting respectively from the strength of current that at least two electrodes of touch-screen flow out, using the detection signal strength exported as touch-screen with value of at least two strength of current monitored.
When touch-screen has at least two electrodes, also can using the detection signal strength exported as touch-screen with value of each strength of current monitored.Can according to the actual needs setting-up time cycle, if when needing accurately to monitor touch-screen, what the time cycle can be arranged is shorter; If when not needing accurately to monitor touch-screen, what the time cycle can be arranged is longer.
Concrete, determine in above-mentioned S12 whether touch-screen the method for error touch control occurs, different with the detection signal strength difference monitored, following two kinds of situations can be comprised:
The first, when the detection signal strength monitored is greater than the first setting threshold value, determine touch-screen generation error touch control.
When touch-screen generation error touch control, have more touch point, the detection signal strength at this moment obtained also can be larger, can determine the first setting threshold value accordingly, be used for representing the lower limit determining touch-screen generation error touch control.Suppose that the first setting threshold value is A, detection signal strength is S, that is as S > A, detection signal strength has exceeded the scope of permission, then think that face etc. position is near to or in contact with touch-screen, at this moment just can determine to there occurs error touch control event, and then can touch-screen be locked, Do not touch screen response touch-control, can certainly close screen display.
The second, when the detection signal strength monitored is greater than the second setting threshold value and is less than the first setting threshold value, determines the touch point number that touch-screen is current, and the second setting threshold value is less than the first setting threshold value; When the touch point number that the touch-screen determined is current reaches the touch point threshold value of setting, determine touch-screen generation error touch control.
When touch-screen be about to sense to there is touch-control time, detection signal strength is smaller, can determine the second setting threshold value accordingly, is used for representing being about to the upper limit of touch-control occurs, and the second setting threshold value should be less than the first setting threshold value.When the detection signal strength monitored is between the first setting threshold value and the second setting threshold value, needs the touch point number determining that touch-screen is current further, when touch point number reaches the touch point threshold value of setting, determine that touch-screen there occurs error touch control.Can determine whether touch-screen there occurs error touch control so more accurately.
Suppose that the second setting threshold value is B, as B < S < A, touch-screen enters alert status, at once touch-control can not be responded, namely need not make an immediate response the operation of user, but wait for that touch panel sensor finally determines input point position, and existing sensor on mobile terminal can be utilized to assist, comprise for automatic adjusting screen brightness light sensor, make a video recording first-class, thus to improve the monitoring accuracy of the positions such as the face of people near event.If touch-screen is finally determined to be input as multiple point, then think to be caused by bump contact, namely may be that the positions such as the face of people and screen contact cause, at this moment just can determine to there occurs error touch control event, and then can touch-screen be locked, Do not touch screen response touch-control, can certainly close screen display.After touch-screen susceptibility is heightened, before face contacts completely with touch-screen, namely may detect multiple pre-terminated contact, thus judge error touch control event in advance, avoid the maloperation in the processes such as language call.
Concrete, the above-mentioned process determining the touch point number that touch-screen is current, specifically comprises: obtain the touch point positional information that the sensor in touch-screen is determined; According to the touch point positional information determined, determine the touch point number that touch-screen is current.
Preferably, after Do not touch in above-mentioned S12 screen response touch-control, also comprise: when determine touch-screen by occur error touch control return to there is not error touch control time, recover touch-screen response touch-control.
After determining that in S12 touch-screen there occurs error touch control, with regard to Do not touch screen response touch-control, at this moment also in the inspection signal intensity of real-time monitoring touch-screen, when being defined as error touch control does not occur, the function of touch-screen response touch-control just can be replied.Which achieves and can monitor touch-screen in real time, change the function of touch-screen response touch-control according to the detection signal strength of monitoring in real time.
Concrete, above-mentionedly determine that touch-screen returns to by there is error touch control error touch control does not occur, specifically comprise: when the detection signal strength monitored is less than the second setting threshold value, determine that touch-screen returns to by there is error touch control error touch control does not occur.
When the detection signal strength monitored is less than the second setting threshold value, think that the operation of touch-screen error touch control terminates, also just determine touch-screen and return to by there is error touch control error touch control does not occur, thus reply touch-screen response touch-control, realize operating normally.
That is as S < B, can be defined as error touch control does not occur, at this moment there is no human body etc. close to touch-screen.When entering into the state of S < B by S > B, early warning contact event can be determined, again recover response touch-control, light touch-screen.
