Embodiment
Consult Fig. 1, the first embodiment of a kind of contact panel anti-disturbance method of the present invention comprises:
Step 101: Received signal strength also detects Received signal strength and whether comprises useful signal; If Received signal strength does not comprise useful signal, carry out step 102; If Received signal strength comprises useful signal, carry out step 103;
Received signal strength is under the state of opening of device, no matter whether receives useful signal, homogeneous straight Received signal strength;
In present embodiment, useful signal is touching signals mainly, namely when finger or other conductor contact contact panels, and the signal that sensor gets; Because touch screen is divided into vector pressure sensing technology touch-screen, resistive technologies touch-screen, capacitance technology touch-screen, infrared technology touch-screen, surface acoustic wave technique touch-screen etc., therefore this useful signal also can be pressure signal, current signal, infrared signal, acoustic signals or other signals, such as radiofrequency signal;
For capacitance plate, when contact panel does not receive useful signal, noise signal is mainly from the grid line of LCD and the closedown repeatedly of data line or switching, now, the signal value of noise signal is discontinuous, rise and fall indefinite, and amplitude is less, as shown in Figure 2, therefore can judge whether Received signal strength is useful signal by the size detecting the continuity or amplitude that receive signal value.
Step 102: preserve Received signal strength as the first signal;
When sensor does not receive useful signal, preserve Received signal strength as the first signal; In present embodiment, the noise signal that processor can collect sensor is analyzed, generation due to noise signal is because the grid line of LCD and the closedown repeatedly of data line or switching, therefore noise signal is likely signal or the noise signal of mechanical periodicity, possess corresponding noise feature or noise characteristic, so processor only can gather the signal in one-period or gather the signal of a period of time, and analytic signal, contrast noise feature or noise characteristic, only store one-period or the noise signal of a period of time; Certainly, because whether neutral signal is mechanical periodicity or random variation, also can carry out collection to this signal always and preserve.
Step 103: preserve Received signal strength as secondary signal;
When sensor receives useful signal, store described Received signal strength and as secondary signal; Because noise signal exists at any time, when therefore gathering useful signal when sensor receives useful signal, also can collect noise signal, therefore secondary signal is the combination of useful signal and noise signal simultaneously.
Step 104: the first signal and secondary signal are processed, obtains useful signal.
This processing mode can be that secondary signal is carried out filtering process, revises, obtain pure useful signal to amplitude; Also can be comparison first signal, in secondary signal, filter out the signal identical with the first signal.
Be different from prior art, present embodiment is by Received signal strength and detect Received signal strength and whether comprise useful signal; If Received signal strength does not comprise useful signal, preserve Received signal strength as the first signal; If Received signal strength comprises useful signal, preserve Received signal strength as secondary signal; First signal and secondary signal are processed, obtains useful signal.Adopt this kind of means, present embodiment gathers the undesired signal of LCD generation with region by timesharing, namely utilize the sensor of the same area when conductor touches and the time of touch receives the first signal and secondary signal respectively, pure useful signal is obtained again by signal transacting, therefore, without the need to sensor being divided into undesired signal acquisition zone and useful signal acquisition zone, make the area of contact panel viewing area be increased to the summation of original undesired signal acquisition zone and useful signal acquisition zone like this, improve the aperture opening ratio of contact panel; And utilize whole panel to gather undesired signal, make the collection of undesired signal more accurate, the useful signal of acquisition is purer.
Consult Fig. 3, the second embodiment of a kind of contact panel anti-disturbance method of the present invention comprises:
Step 301: Received signal strength and pre-stored threshold values signal are compared, judges whether Received signal strength is less than threshold signal, if so, carry out step 302; If not, carry out step 303;
The amplitude of threshold signal sets according to the first signal and secondary signal, is generally that boundary is between the first signal and secondary signal; As shown in Figure 4, the first signal is noise signal, and therefore signal value is discontinuous, rise and fall indefinite, and amplitude is less; Secondary signal is the summation of useful signal and noise signal, owing to there being the existence of noise signal, secondary signal is also yo-yo, but the amplitude of secondary signal is larger, therefore the threshold signal of one boundary between the first signal and secondary signal amplitude can be set according to the amplitude of the first signal and secondary signal, and save, when receiving signal, by Received signal strength and threshold signal comparison, thus judge that Received signal strength is the first signal or secondary signal.
Step 302: when Received signal strength is less than threshold signal, judges that Received signal strength does not comprise useful signal and preserves Received signal strength as the first signal;
Step 303: when Received signal strength is more than or equal to threshold signal, judges that Received signal strength comprises useful signal and preserves Received signal strength as secondary signal;
When multilevel iudge Received signal strength and threshold signal amplitude size, because the first signal and secondary signal are all yo-yo, then can by the maximal value of the first signal and secondary signal, minimum value or mean value be compared with threshold signal; Such as, be set to when the maximal value of Received signal strength is less than threshold signal, judge that Received signal strength is as noise signal, and as the first signal; When the minimum value of Received signal strength is greater than or equal to threshold signal, judge the summation of Received signal strength as useful signal and noise signal, and as secondary signal.
Step 304: the first signal and secondary signal are carried out asking difference operation and obtaining difference signal, and using difference signal as useful signal.
As shown in Figure 5, Fig. 5 (a) is the first signal coordinates schematic diagram, and Fig. 5 (b) is secondary signal coordinate schematic diagram, and Fig. 5 (c) is useful signal coordinate schematic diagram; Because the collection of the first signal and secondary signal is timesharing, therefore two signals can not mate on time coordinate (X-axis in figure), but the generation due to the first signal is periodically, and the noise in secondary signal is roughly the same with the first signal in one-period, such as, multiple extreme values of multiple extreme value of the first signal and secondary signal can be compared, first signal and secondary signal can be carried out like this mating periodically, judging the time of each extraordinary noise in each cycle;
Then the first signal and secondary signal are carried out asking difference operation, according to the first signal and the secondary signal of coupling, corresponding subtraction is done to the signal of each time point, namely the amplitude of secondary signal first extreme value deducts the amplitude of the first signal first extreme value, the amplitude of secondary signal secondary extremal deducts the amplitude of the first signal secondary extremal, the like, obtain difference signal like this, and using this difference signal as useful signal.
Particularly, as shown in Figure 6, when the first signal is mated with secondary signal, the extreme value of each signal is carried out corresponding coupling, each extreme value of the first signal as figure solid line can be mated with secondary signal, and the first signal of dotted line can not mate with secondary signal, therefore only when the first signal mates with the extreme value of secondary signal, just difference operation is asked to the first signal and secondary signal.
Be different from prior art, present embodiment is by comparing Received signal strength and threshold signal, judge whether Received signal strength is useful signal, when not receiving useful signal, the noise signal received is carried out being stored as the first signal, when receiving useful signal, as secondary signal, by coupling extreme value, first signal and secondary signal are processed, first signal and secondary signal are carried out asking difference operation from secondary signal, filter out the first signal, thus obtains pure useful signal; Mated by the extreme value increasing judgement first signal and secondary signal, the signal amplitude of corresponding time in respective same period can be filtered out accurately when making to screen the first signal in secondary signal, can not be only the mean value of screening first signal or large probable value, the coupling of the first signal and secondary signal will be made so more to prepare, screening is more accurate, and the useful signal of acquisition is more pure.
Consult Fig. 7, the 3rd embodiment of a kind of contact panel anti-disturbance method of the present invention comprises:
Step 701: Received signal strength also detects Received signal strength and whether comprises useful signal; If Received signal strength does not comprise useful signal, carry out step 702; If Received signal strength comprises useful signal, carry out step 703;
Step 702: periodically gather at least two noise signals and average value signal is obtained, and using average value signal as the first signal to the computing of averaging of at least two noise signals;
Due to randomness and the uncontinuity of noise signal, in the different position of contact panel, the noise signal that produces of different time all may be different, therefore in order to obtain noise signal more easily and filter out noise signal from useful signal, present embodiment adopts and periodically gathers at least two noise signals and the mode of averaging;
Particularly, here the mode compared with threshold signal in the second embodiment can also be adopted, when Received signal strength is less than threshold signal, judge that the signal received is noise signal, and periodically gather noise signal, it should be noted that: the reception of signal is reception, just collection signal is by the cycle;
Before receiving useful signal, often gather a noise signal all do mean value process with each noise signal gathered before and preserve as the first signal, like this, the first signal in storer constantly updates, along with new noise signal changes, can envision, abundant when noise signals collecting, maintenance is stablized by the first signal in storer;
In addition, the cycle gathering noise signal can be arranged arbitrarily, cycle is less, the noise signal gathered is more accurate, when enough hour of cycle, can continuous acquisition be thought, namely can the continuous or discontinuous signal gathered be carried out integration and be averaged, the noise signal of collection can be made so more accurate.
Step 703: preserve Received signal strength as secondary signal;
Step 704: the first signal and secondary signal are processed, obtains useful signal.
Because the first signal is the mean value that periodic sampling obtains multiple noise signal, therefore when the first signal and secondary signal are processed, only need secondary signal to deduct a fixing mean value, thus obtain useful signal.
Be different from prior art, present embodiment, when not receiving useful signal, obtains noise signal by periodically sampling, and to average process to multiple noise signal, and using this average value signal as the first signal, make the acquisition of the first signal convenient, quick; In addition, when processing the first signal and secondary signal, due to the average value signal that the first signal is multiple noise signal, when screening, easilier from secondary signal, filter out the first signal, avoid loaded down with trivial details comparison extreme value and the process of coupling, make corresponding more rapid to secondary signal of contact panel, alleviate the burden of processor.

Whether processor 802 comprises useful signal for detecting Received signal strength, if Received signal strength does not comprise useful signal, preserves Received signal strength as the first signal; If Received signal strength comprises useful signal, preserve Received signal strength as secondary signal;
Processor 802, also for the first signal and secondary signal being processed, obtains useful signal.
In other embodiments, processor is also compared for just Received signal strength and pre-stored threshold values signal, judges whether Received signal strength is less than threshold signal; When Received signal strength is less than threshold signal, judge that Received signal strength does not comprise useful signal; When Received signal strength is more than or equal to threshold signal, judge that Received signal strength comprises useful signal.
In other embodiments, processor also comprises a subtracter; Subtracter is used for the first signal and secondary signal to carry out asking difference operation and obtaining difference signal, and using difference signal as useful signal.
