Embodiment one
Fig. 1 is a kind of flow chart of the method for the capacitance plate touch control detection provided in the embodiment of the present invention one, the present embodiment
The situation of enhancing capacitance plate antijamming capability is applicable to, this method can be performed by capacitance plate touch control detection device, specifically
Include the following steps：
Step S110：Possess the touch-control drive signal of the first signal attribute to the output of touch-control emitter, obtain and connect from touch-control
Receive the touch control detection signal that pole detects.
Change of the capacitance plate (capacitive touch screen) by detecting electric current in capacitance confirms the generation position of touch control operation, uses
Different according to the generation type of capacitance in the two extremely touch control electrodes for forming capacitance, the distribution of touch control electrode is different.One kind is gold
Belong to piece with ground form capacitance, specifically, be fabricated to laterally and longitudinally electrod-array, these horizontal and vertical electrodes respectively with
Ground forms capacitance, and touch-control drive signal and touch control detection signal come from same electrode, and this detection mode is right commonly referred to as from appearance
For touch chip, under capacitance type, touch-control drive signal is identical with the target of touch control detection signal；Another kind is sheet metal
Capacitance is formed with sheet metal, specifically, is fabricated to laterally and longitudinally electrod-array, two neighboring electrode forms electricity in array
Hold, one of to be used as touch-control emitter, another is as touch-control receiving pole；Alternatively, two layers of corresponding electrod-array is fabricated to,
Electrode in one layer is commonly referred to as mutual as touch-control receiving pole, this detection mode as touch-control emitter, another layer of electrode
Hold, for touch chip, under mutual capacitance type, touch-control drive signal is different with the target of touch control detection signal.But whether
How is specific touch control electrode layout type, launches touch-control drive signal and receives touch control detection signal, by curent change most
Realize that the Integral Thought of touch control detection is identical eventually.
In the present solution, according to the difference of touch-control drive signal and the signal attribute of touch control detection signal, it can optimize pair
The exclusion of interference signal.Signal attribute includes frequency and/or coding structure, when the first signal attribute of touch-control drive signal and production
When the touching signals attribute that the touch-control source of the raw touch control detection signal possesses is identical, it can be determined that go out not interfering with letter
Number, capacitance plate can be worked normally.
Step S120：If the touching signals attribute that the touch-control source for producing the touch control detection signal possesses and the described first letter
Number attribute difference, then adjust first signal attribute to expand the diversity factor with the touching signals attribute.
Wherein, the touch-control source for producing touch control detection signal can be the touch-control such as finger or felt pen source or ring
Interference signal in border；Diversity factor refers to the difference degree of touching signals attribute and the first signal attribute, can be frequency difference
Degree, frequency difference degree refer to the absolute value of the difference of the frequency of touch control detection signal and the frequency of touch-control drive signal；Can also be

The touching signals attribute that the touch-control source of the raw touch control detection signal possesses is differed with the first signal attribute, that is, produces described touch
The touching signals attribute and the diversity factor of the first signal attribute that the touch-control source of control detection signal possesses are not zero, then may determine that
The touch control detection signal that touch-control receiving pole receives is interference signal, is not the touch-control drive signal of touch-control emitter transmitting, this
When, it is necessary to adjust the first signal attribute to expand the diversity factor with touching signals attribute, until possessing touching for the first signal attribute
Control drive signal and the signal attribute of interference signal differ greatly, and can quickly judge touch control detection signal is touched from normal
Control operation still comes from interference source, and such interference signal will reduce the influence that capacitance plate works normally.
The operation principle of the capacitance plate touch control detecting method：Possesses the touch-control of the first signal attribute to the output of touch-control emitter
Drive signal, obtains the touch control detection signal detected from touch-control receiving pole, and wherein attribute includes frequency and/or coding structure,
When the touching signals attribute that the touch-control source for producing touch control detection signal possesses is identical with the first signal attribute of touch-control drive signal
When, that is, produce touching signals attribute and the first signal attribute of touch-control drive signal that the touch-control source of touch control detection signal possesses
Diversity factor is zero, then there is no interference signal；If the touching signals attribute that the touch-control source for producing touch control detection signal possesses is with touching
Control drive signal the first signal attribute it is different when, that is, produce touching signals attribute that the touch-control source of touch control detection signal possesses with
The diversity factor of first signal attribute of touch-control drive signal is not zero, then there are interference signal, then needs the letter of adjustment first at this time

Embodiment two
Fig. 2 is a kind of flow chart of the method for the capacitance plate touch control detection provided in the embodiment of the present invention two, such as Fig. 2 institutes
Show, this method specifically includes：
Step S210：Possess the touch-control drive signal of the first signal attribute to the output of touch-control emitter, obtain and connect from touch-control
Receive the touch control detection signal that pole detects.
Wherein, signal attribute can be frequency and/or coding structure.If signal attribute is frequency, when touch control detection is believed
When number identical with the frequency of touch-control drive signal, then there is no interference signal, capacitance plate to be then normally carried out touch.In reality
In operating process, there are some interference sources near capacitance plate, when the interference signal frequency and touch-control that interference source is sent drive
The frequency of signal is unequal, then the touch control detection signal that touch-control receiving pole receives may be interference signal, it is necessary to be examined to touch-control
Survey signal and be further analyzed processing, so as to avoid influence of the interference signal to capacitance plate touch signal.
Step S220：Confirm the secondary signal attribute of the touch control detection signal and the first signal category by setpoint frequency
The diversity factor of property.
Specifically, if signal attribute is frequency, setting touch emitter output frequency is the touch-control drive signal of 30Hz,
The frequency for the touch control detection signal that touch-control receiving pole detects is 35Hz, then confirm touch-control drive signal and touch control detection signal it
Between diversity factor, the concrete numerical value of the diversity factor is 5Hz.
If attribute is frequency and coding structure, coding structure can be the signal types such as square wave, sine wave or rectangular wave, then
Touch-control drive signal that can be using setting touch emitter output frequency as 30Hz square waves, the touch control detection that touch-control receiving pole detects
The frequency of signal is 30Hz sine waves, even if then touch-control drive signal is identical with the frequency of touch control detection signal, but encodes knot
Structure is different, also confirms degree of having differences between touch-control drive signal and touch control detection signal.
Typically, the interference that capacitance plate can be subject to is stable, and interference signal does not have generally too big after confirming
Change, confirms interference signal and can maintain to stablize touch control detection for a long time after being adjusted, therefore need not be real-time
Comparison state is maintained to the secondary signal attribute of touch control detection signal, carrying out a diversity factor every a period of time confirms, such as
Fruit has and needs subsequently to be adjusted.
During concrete implementation, the touching signals attribute in touch-control source can be judged by the detection to touch-control source, separately
A kind of more direct judgment mode is by judging the secondary signal attribute of touch control detection signal.If touch control detection signal
Secondary signal attribute and the diversity factor of first signal attribute be not zero, then may determine that what touch-control receiving pole received
Touch control detection signal is interference signal, is not the touch control detection signal that normal user's operation produces, needs to judge difference at this time
Within a preset range whether degree.If diversity factor is within a preset range, illustrate what interference signal worked normally capacitance plate
Influence very big, it is necessary to which the first signal attribute for adjusting touch-control drive signal is reduced with expanding the diversity factor between interference signal
Influence of the interference signal to capacitance plate；If diversity factor is more than preset range, the attribute of interference signal and touch-control drive signal
Attribute differs greatly, and the influence very little that interference signal works normally capacitance plate, need not adjust touch-control drive signal at this time
Attribute.
Step S230：If the diversity factor of the frequency of the frequency of the touch control detection signal and the touch-control drive signal is the
Between one threshold value and the second threshold value, then the diversity factor is confirmed within a preset range.
In specific diversity factor deterministic process, it can be compared based on specific signal attribute.If signal attribute is
Frequency, when the frequency for the touch control detection signal that the frequency and touch-control receiving pole of the touch-control drive signal of touch-control emitter output detect
Rate differs greatly, and more than preset range, then the touch control detection signal detected is evident as interference signal, and to the work of capacitance plate
Do not influence；If the touch control detection letter that the frequency and touch-control receiving pole of the touch-control drive signal of touch-control emitter output detect
Number frequency phase-difference it is little, the difference of frequency is between the first threshold value and the second threshold value of setting, you can thinks both differences
Different degree is within a preset range.Specifically, the frequency of signal can be detected using setting touch as 35Hz, and the frequency of touch-control drive signal
For 30Hz, the first threshold value is 0.1Hz, and the second threshold value is 10Hz, due between touch control detection signal and touch-control drive signal
Diversity factor be 5Hz, between the first threshold value and the second threshold value, it may be considered that diversity factor between the two is in default model
In enclosing.
If signal attribute is frequency and coding structure, if the frequency and touch-control of the touch-control drive signal of touch-control emitter output
The frequency for the touch control detection signal that receiving pole detects differs but coding structure is identical, then the touch-control that touch-control receiving pole detects
Detection signal is interference signal, it is thus necessary to determine that whether the diversity factor between the frequency and touch-control drive signal of interference signal is default
In the range of；If the frequency of touch control detection signal is identical from the frequency of the touch-control drive signal and coding structure is different, directly
Confirm diversity factor within a preset range.Specifically, the touch control detection signal detected when touch-control receiving pole for frequency 30Hz just
String ripple, and the square wave that touch-control drive signal is 30Hz, even if then both frequencies are identical, can also directly confirm that touch control detection is believed
Number and touch-control drive signal diversity factor within a preset range.
Step S240：The frequency of the touch-control drive signal is improved or reduced to expand the frequency with the touch control detection signal
The diversity factor of rate.
Diversity factor between touch control detection signal and touch-control drive signal is bigger, then touch control detection signal is interference signal
Possibility is bigger, capacitance plate be interfered signal influence with regard to smaller.When between touch control detection signal and touch-control drive signal
Diversity factor within a preset range when, then can adjust the frequency of touch-control drive signal to expand diversity factor between the two.Specifically
, if the frequency of setting touch detection signal is 35Hz, and the frequency of touch-control drive signal is 30Hz, and the first threshold value is
0.1Hz, the second threshold value is 10Hz, since the diversity factor between touch control detection signal and touch-control drive signal is in the first threshold value
And second between threshold value, then the frequency of touch-control drive signal can be reduced until both diversity factoies are more than 10Hz；If setting
The frequency of touch control detection signal is 20Hz, and the frequency of touch-control drive signal is 25Hz, and the first threshold value is 0.1Hz, second
Limit value is 10Hz, since the diversity factor between touch control detection signal and touch-control drive signal is in the first threshold value and the second threshold value
Between, then the frequency of touch-control drive signal can be improved until diversity factor between the two is more than 10Hz.
If the touch control detection signal that the frequency and touch-control receiving pole of the touch-control drive signal of touch-control emitter output detect
Frequency it is identical but coding structure differs, then directly confirm the diversity factor of touch-control drive signal and touch control detection signal default
In the range of, the signal detected by touch-control receiving pole is interference signal.In order to avoid the influence that interference signal works capacitance plate,
Only need the difference difference that the frequency for adjusting touch-control emitter makes the frequency of itself and interference signal larger at this time until interference signal
Work of the frequency on capacitance plate does not influence；Alternatively, the frequency and coding structure of adjustment touch-control emitter cause interference signal
The work of frequency and coding structure on capacitance plate does not influence.
In embodiments of the present invention, when the frequency between touch control detection signal and touch-control drive signal is unequal and both it
Between diversity factor between the first threshold value and the second threshold value of setting, alternatively, touch control detection signal and touch-control drive signal
Between frequency it is equal and when coding structure is different, the diversity factor for confirming both this parts then illustrates capacitance plate within a preset range
Be interfered the influence of signal, can expand the diversity factor with touch control detection signal by adjusting the frequency of touch-control drive signal,
Frequency away from interference signal, reduces the interference to capacitance plate work.
