Embodiment
Refering to Fig. 1, a kind of first embodiment of contact panel anti-disturbance method of the present invention includes:
Step 101:Reception signal simultaneously detects whether reception signal includes useful signal;If reception signal does not include effectively letter
Number, carry out step 102;If reception signal includes useful signal, step 103 is carried out;
Reception signal be in the state of opening of device, regardless of whether receive useful signal, homogeneous straight reception signal;
In present embodiment, useful signal is mainly touching signals, i.e., when finger or other conductors contact contact panel,
The signal that sensor is got;Because touch screen is divided into vector pressure sensing technology touch-screen, resistive technologies touch-screen, electric capacity skill
Art touch-screen, infrared technology touch-screen, surface acoustic wave technique touch-screen etc., therefore the useful signal can also be pressure letter
Number, current signal, infrared signal, acoustic signals or other signals, such as radiofrequency signal;
By taking capacitance plate as an example, when contact panel does not receive useful signal, noise signal essentially from LCD grid line and
The closing repeatedly or switching of data wire, now, the signal value of noise signal is discontinuous, ups and downs, and amplitude compared with
It is small, as shown in Fig. 2 therefore the continuity of signal value or the size of amplitude can be received to judge reception signal by detection
Whether it is useful signal.
Step 102:Reception signal is preserved as the first signal;
When sensor does not receive useful signal, reception signal is preserved as the first signal;In present embodiment, processing
The noise signal that device can collect to sensor is analyzed, because the generation of noise signal is the grid line sum because LCD
According to the closing repeatedly or switching of line, therefore noise signal is likely to be the signal or noise signal of mechanical periodicity, possesses corresponding
Noise feature or noise characteristic, so processor can only collection a cycle in signal or gather a period of time letter
Number, and signal Analysis, noise feature or noise characteristic are compareed, only stores a cycle or the noise signal of a period of time;When
So, because whether neutral signal is mechanical periodicity or random change, preservation can also be acquired always to the signal.
Step 103:Reception signal is preserved as secondary signal;
When sensor receives useful signal, store the reception signal and be used as secondary signal;Because noise signal
It is existing at any time, therefore when be acquired when sensor receives useful signal to useful signal, can also adopts simultaneously
Collect noise signal, therefore secondary signal is the combination of useful signal and noise signal.
Step 104:First signal and secondary signal are handled, obtain useful signal.
The processing mode can be that secondary signal is filtered into processing, and amplitude is modified, and obtain pure effective
Signal;Can also compare the first signal, be filtered out in secondary signal and the first signal identical signal.
Prior art is different from, present embodiment is by reception signal and detects whether reception signal includes useful signal;
If reception signal does not include useful signal, reception signal is preserved as the first signal;If reception signal includes useful signal, preserve
Reception signal is as secondary signal;First signal and secondary signal are handled, obtain useful signal.Using such a means,
Present embodiment gathers interference signal caused by LCD by timesharing with region, i.e., using the sensor of the same area in conductor
The first signal and secondary signal are received during touch and when not touching respectively, then pure useful signal is obtained by signal transacting,
It is therefore not necessary to which sensor is divided into interference signal acquisition zone and useful signal acquisition zone, so make contact panel viewing area
Area is increased to the summation of original interference signal acquisition zone and useful signal acquisition zone, improves the aperture opening ratio of contact panel;And
Interference signal is gathered using whole panel, makes the collection of interference signal more accurate, the useful signal of acquisition is purer.
Refering to Fig. 3, a kind of second embodiment of contact panel anti-disturbance method of the present invention includes:
Step 301:Reception signal is compared with pre-stored threshold values signal, judges whether reception signal is less than threshold value and believes
Number, if so, carrying out step 302;If it is not, carry out step 303;
The amplitude of threshold signal is set according to the first signal and secondary signal, is generally that boundary believes in first
Number between secondary signal;As shown in figure 4, the first signal is noise signal, therefore signal value is discontinuous, ups and downs,
And amplitude is smaller;Secondary signal is the summation of useful signal and noise signal, due to having the presence of noise signal, secondary signal
It is yo-yo, but the amplitude of secondary signal is larger, therefore can be set according to the amplitude of the first signal and secondary signal
Threshold signal of one boundary between the first signal and secondary signal amplitude, and save, when receiving signal, believe receiving
Number compared with threshold signal, so as to judge that reception signal is the first signal or secondary signal.
Step 302:When reception signal is less than threshold signal, judge that reception signal does not include useful signal and preserves reception
Signal is as the first signal;
Step 303:When reception signal is more than or equal to threshold signal, judge that reception signal includes useful signal and preserved
Reception signal is as secondary signal;
When multilevel iudge reception signal and threshold signal amplitude size, because the first signal and secondary signal are
It is yo-yo, then can by one in the maximum, minimum value or average value by the first signal and secondary signal with
Threshold signal is compared;For example, being arranged to when the maximum of reception signal is less than threshold signal, it is miscellaneous to judge reception signal
Signal is interrogated, and is used as the first signal;When the minimum value of reception signal is more than or equal to threshold signal, judge that reception signal is
The summation of useful signal and noise signal, and it is used as secondary signal.
Step 304:First signal and secondary signal are carried out seeking difference operation and obtain difference signal, and by difference signal
As useful signal.
As shown in figure 5, Fig. 5 (a) is the first signal coordinates schematic diagram, Fig. 5 (b) is secondary signal coordinate schematic diagram, Fig. 5
(c) it is useful signal coordinate schematic diagram;Because the collection of the first signal and secondary signal is timesharing, thus two signals when
Between can not match on coordinate (X-axis in figure), but because the generation of the first signal is periodically, and in secondary signal
Noise be roughly the same with the first signal in a cycle, such as, can be by multiple extreme values and second of the first signal
Multiple extreme values of signal are compared, and the first signal and secondary signal can so be carried out to matching periodically, judged every
Time of the individual extraordinary noise in each cycle;
Then the first signal and secondary signal are carried out seeking difference operation, according to the first signal and secondary signal of matching,
Corresponding subtraction is done to the signal at each time point, i.e. the amplitude of the extreme value of secondary signal first subtracts first the first pole of signal
The amplitude of value, the amplitude of secondary signal secondary extremal subtract the amplitude of the first signal secondary extremal, the like, it is achieved in that difference
Value signal, and using the difference signal as useful signal.
Specifically, it is by the extreme value of each signal as shown in fig. 6, when the first signal is matched with secondary signal
Matched corresponding to carrying out, as each extreme value of the first signal of figure solid line can be matched with secondary signal, and the first of dotted line the letter
Number it can not be matched with secondary signal, therefore only when the first signal matches with the extreme value of secondary signal, just to first
Signal and secondary signal carry out seeking difference operation.
Prior art is different from, present embodiment receives letter by the way that reception signal compared with threshold signal, is judged
Number whether it is useful signal, when not receiving useful signal, the noise signal received is subjected to storage as the first signal,
When receiving useful signal, as secondary signal, by matching extreme value, the first signal and secondary signal are handled, will
First signal and secondary signal carry out asking difference operation to filter out the first signal from secondary signal, pure effective so as to obtain
Signal;Judge that the extreme value of the first signal and secondary signal is matched by increase so that the first letter is screened in secondary signal
Number when can accurately filter out the signal amplitude of the corresponding time in respective same period, will not only be screening one the
The average value of one signal or big probable value, thus can cause the matching of the first signal and secondary signal more to prepare, and screening is more
Add precisely, the useful signal of acquisition is more pure.
Refering to Fig. 7, a kind of 3rd embodiment of contact panel anti-disturbance method of the present invention includes:
Step 701:Reception signal simultaneously detects whether reception signal includes useful signal;If reception signal does not include effectively letter
Number, carry out step 702;If reception signal includes useful signal, step 703 is carried out;
Step 702:Periodically gather at least two noise signals and at least two noise signals are averaged
Computing obtains average value signal, and using average value signal as the first signal;
Due to the randomness and discontinuity of noise signal, caused by the different position of contact panel, different time
Noise signal all may be different, therefore in order to more easily obtain noise signal and noise signal be filtered out from useful signal,
Present embodiment is by the way of periodically gathering at least two noise signals and averaging;
Specifically, here can also using in second embodiment compared with threshold signal by the way of, when reception signal is small
When threshold signal, the signal for judging to receive is noise signal, and periodically gathers noise signal, it should be noted that:
The reception of signal is reception, and it is by the cycle simply to gather signal;
Before useful signal is received, often one noise signal of collection is done flat with each noise signal gathered before
Average value processing is simultaneously preserved as the first signal, and so, the first signal in memory is to constantly update, and is with new noise
Signal and change, it is envisioned that enough when noise signal acquisition, the first signal in memory will keep stable;
In addition, the cycle of collection noise signal can arbitrarily be set, the cycle is smaller, and the noise signal of collection is more smart
Standard, when the cycle is sufficiently small, it is believed that be continuous acquisition, you can integrated simultaneously with the continuously or discontinuously signal to collection
Average, such that the noise signal of collection is more accurate.
Step 703:Reception signal is preserved as secondary signal;
Step 704:First signal and secondary signal are handled, obtain useful signal.
Because the first signal is the average value that periodic sampling obtains multiple noise signals, therefore by the first signal and second
When signal is handled, it is only necessary to secondary signal is subtracted into a fixed average value, so as to obtain useful signal.
Prior art is different from, present embodiment is miscellaneous by periodically sampling acquisition when not receiving useful signal
Signal is interrogated, processing of averaging is carried out to multiple noise signals, and using the average value signal as the first signal so that the first letter
Number acquisition it is more convenient, fast;In addition, when handling the first signal and secondary signal, because the first signal is more
The average value signal of individual noise signal, when screening, it is easier to the first signal is filtered out from secondary signal, is avoided cumbersome
Comparison extreme value and matching process so that contact panel alleviates processor to the corresponding more rapid of secondary signal
Burden.
