In the case where the effective instruction information of noise indication signal, the structure of facilitating chip internal circuit.
Optionally, after removing screen data affected by noise, further includes: in the screen number for receiving touch screen return
In the case where several times, the valid data obtained to pre-determined number in multiple are averaged, it is above-mentioned be averaged carry out it is tired
Normalized is summed it up, takes the sum of overall specifically, cumulative, normalization is averaged；After being averaged, after obtaining processing
Data；According to the data that obtain that treated, the touch location of touch screen is determined.
The above-mentioned data sent to touch screen of ordinary circumstance are generally multiple, that is to say, sent out with certain frequency to touch screen
Send data.For example, above-mentioned carrier signal, is scanned touch screen, interval time is very short on the data time of Multiple-Scan.
In specifically processing data, (i.e. do not detecting that the element of analog circuit generates when reception data after determining that data are effective
Noise), the data are stored, is sent in memory and stores, is called for computing module and carries out accumulation calculating and normalized, i.e.,
The above-mentioned process being averaged, to calculate touch screen position.Above-mentioned be averaged can increase data stability, tie analysis
Fruit is more acurrate.
Optionally, it includes: to count to exist to make an uproar that whether the circuit internal components for detecting the touch chip of touch screen, which generate noise,
The quantity of the screen data of sound；According to the quantity of statistics, detection threshold value is adjusted, wherein detection threshold value is for detecting touch screen
Whether the circuit internal components of touch chip generate the detection threshold value of noise；According to the detection threshold value of adjustment, touch screen is detected
Whether the circuit internal components of touch chip generate noise.
Since the parameter of the noise under different operating conditions is not identical, in the present embodiment, according to repeatedly in by noise shadow
Whether the number of loud screen data, adjustment generate the inspection of noise for detecting the circuit internal components of the touch chip of touch screen
Survey threshold value.For example, the changing rule of noise can be found, if noise becomes according to above-mentioned multiple screen data affected by noise
Change it is regular, can be controlled according to the noise changing rule detection precognition variation；If noise variation is without rule or makes an uproar
Sound changing rule is complicated and rule is caused to be difficult in the case where determining, can use Principle of Statistics, to determine noise variation
Regulatory thresholds.For example, finding out the multiple screen data affected by noise according to above-mentioned multiple screen data affected by noise
Desired value, above-mentioned regulatory thresholds are determined according to the desired value.
It, can be according to screen data affected by noise when above-mentioned use Principle of Statistics determines above-mentioned regulatory thresholds
Accumulation and variation, are updated the desired value.For example, can be in certain time or data accumulation affected by noise to one
When determining number, the multiple impacted screen data of determining regulatory thresholds is determined again, to be carried out to regulatory thresholds
It redefines and updates, can effectively improve the accuracy rate of noise measuring.
