Embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is described in further detail, but protection scope of the present invention is not limited to the following stated.
At first, set forth by reference to the accompanying drawings the principle of work of capacitance plate, Fig. 1 is the ball bearing made using situation of finger touch capacitance touch screen, and in the mutual capacitance coupling, A, B sensor block are respectively the transmitting terminal of pumping signal and the receiving terminal of measuring-signal.When the coverture on the finger touch sensor block, because finger and human body can be considered to conductor, capacitor C board between capacitor C body between human body and the earth and equipment ground and the earth is enough large, ac-excited signal to high frequency only has very little capacitive reactance, so can think that the electromotive force of finger in touch system is approximately the electromotive force GND on equipment ground.In the field coupled of mutual capacitance, because the electromotive force of finger in touch system is approximately the electromotive force GND on equipment ground, the electromotive force of sensor block A and the sensor block B all electromotive force than finger is high, the coupling that will produce electricity between sensor block A and sensor block B and finger, this just means generation coupling capacitance CFT and CFR between sensor block A and sensor block B and finger.When the ac-excited signal of high frequency is applied on the sensor block A, pointed capacitor C FT and CFR divides the part of pouring off via mutual capacitance CM to the electric current of RX, the electric current of receiving terminal RX will be less than originally, it is the minimizing of mutual capacitance CM with regard to equivalence like this, so we say that finger touch reduces mutual capacitance usually.
Fig. 2 is the ball bearing made using situation when water droplet occurring on the capacitance touch screen, when water is fallen on the touch-screen, because water conducts electricity, can think conductor, and it also will change the field coupled between sensor block A and the sensor block B.But the surface area of water is compared human body and wanted little very many, and the capacitor C body between human body and the earth has not existed, and the electric capacity between water droplet and the earth is very little, and is little of almost zero.The electromotive force of water droplet in touch system can not be approximately the electromotive force GND on equipment ground, and its electromotive force is determined by the electromotive force of sensor block A and sensor block B.Based on general knowledge, its electromotive force should be between the electromotive force of the electromotive force of sensor block A and sensor block B.In the field coupled of mutual capacitance, water droplet forms capacitor C WT and CWR with sensor block A and sensor block B respectively, can think that these two electric capacity are the two ends that are connected in parallel on again CM after the series connection, so to the screen of mutual capacitance, water droplet does not resemble finger touch reduces mutual capacitance, but mutual capacitance is increased! It is same because two electric capacity that water droplet produces are the two ends that are connected in parallel on again CM after the series connection, the value of series capacitance will be less than any one electric capacity in the series capacitance, for a water droplet with the finger size diameter, the signal intensity that the signal intensity that it produces also will produce less than finger touch certainly, usually it is 1/4 size of finger touch signal, but the signal intensity that it and finger touch produce is reciprocal.
Because mobile phone touches mutual capacitance is reduced, water droplet but makes mutual capacitance increase, so be can not cause false triggering on the principle when water droplet is applied to the capacitance touch screen surfaces, but near the regional and arid region acting in conjunction of water droplet but can make the capacitance plate capacitance change, finally cause the situation of false triggering to occur, Fig. 3 is the situation that water droplet causes false triggering: in the finger touch situation of normal condition, the AD conversion difference that finger touch obtains is 4. greater than triggering threshold values 5., so can realize triggered as normal, under the water droplet situation, because the water droplet zone is unbalanced, water droplet zone and arid region interact, 2. negative offset all of AD conversion value in the time of can causing capacitive-based directrix value 1. with no touch, and the side-play amount of capacitive-based directrix value is greater than the AD conversion value, when 3. the difference that is offset between the two just can cause triggering greater than triggering threshold values 5. the time, but the triggering of this moment is wrong, i.e. false triggering has occured.
Because the false triggering that water droplet causes possibly can't be avoided, but can use software that the seizure and the post-processed that trigger are filtered, the false triggering that water droplet causes is screened out from various triggering situations, make it be different from triggered as normal that mobile phone touch to produce and it is filtered out.
Can draw the basic law that the water droplet false triggering is different from finger touch by realistic simulation:
(1) false triggering that water droplet causes on multi-point touch screen usually can be more than plural shake-up, and its trigger rule shows as multiple spot and triggers simultaneously, and can not stop in the short time, present multiconductor length by situation;
(2) because the flowability of water droplet, its changes in coordinates can show to point long some by under the situation different, in case water droplet causes false triggering, its coordinate can slowly change in the certain area certain hour, coordinate is more fixing on time and finger is long, and the changes in coordinates scope is less than the variation range that water droplet triggers.
For above situation, can judge the water droplet false triggering and it is filtered out by the present invention, as shown in Figure 4:
A kind of method that prevents the false triggering of capacitance touch screen water droplet, it may further comprise the steps:
(1) three parameter: A, B and the C of water droplet false triggering judged in initialization, and it is initialized as respectively vacation;
(2) the kernel-driven layer detects number of contacts, and when number of contacts during more than 2, A is set to very;
(3) triggering times in the kernel-driven layer detects Preset Time, if when the triggering times within the unit interval was looked into pre-set threshold value, B is set to very, but does not filter current trigger event;
(4) be exclusively used in the coordinate transition amplitude threshold parameter of judging the water droplet false triggering in the setting of kernel-driven layer, predetermined follows the tracks of long contact coordinate transition of pressing under the state at the kernel-driven layer, when detecting coordinate transition amplitude and equal or exceed default threshold parameter, C is set to very, but does not filter current trigger event;
(5) two condition: X and the Y that starts filter action is set;
(6) when A, B, the equal true time of C, then judge the false triggering that current triggering causes as water droplet, and record current false triggering coordinate figure, and continue to detect multiple spot continuous trigger event thereafter, be used for judging whether follow-up multiple spot continuous trigger belongs to the continuity of current false triggering;
(7) the kernel-driven layer detects number of contacts, when number of contacts more than or equal to 2 the time, X is set to very;
(8) the kernel-driven layer detect the contact coordinate value with before the false triggering coordinate figure judged approach then that Y is set to very;
(9) when X and Y be true time simultaneously, judge that current triggering as the last time continuity of water droplet false triggering, filters current trigger event.
Whether the present invention satisfies more than or equal to two trigger points, triggering times in the unit interval greater than pre-set threshold value and coordinate transition amplitude greater than default amplitude threshold values simultaneously by detect touching event, judge then that if not satisfying simultaneously current triggering is not that water droplet causes, and finishes this detecting process immediately; If satisfy simultaneously then judge what current triggering caused as water droplet, then continue to detect follow-up trigger point, if the false triggering coordinate figure that satisfy simultaneously more than or equal to two trigger points, coordinate figure and before judgement the trigger point approaches, judge that then current trigger event is the last time continuity of water droplet false triggering, filter out current trigger event, this false triggering conductively-closed that water droplet is caused is fallen, if do not satisfy simultaneously two conditions, judge that then current event is not the false triggering event, finish current detecting process.
