Clearly to illustrate in the embodiment of the present invention according to the test data of each Frequency point from frequency range to be debugged
The implementation process of the middle target frequency point for determining normal work, the embodiment of the present invention propose the working frequency of another touch-screen
Adjustment method, Fig. 2 are the schematic flow sheet of the working frequency adjustment method for the touch-screen that another embodiment of the present invention proposes.
As shown in Fig. 2 on the basis of embodiment as shown in Figure 1, step 103 may comprise steps of：
Step 201, according to the test data of each Frequency point, the touch-control accuracy rate of each Frequency point is calculated.
Wherein, touch-control accuracy rate is used to indicate the order of accuarcy to touch control operation test, and order of accuarcy is higher, and touch-control is accurate
Rate value is bigger, and order of accuarcy is lower, and touch-control accuracy rate value is smaller.
In the present embodiment, in frequency range to be debugged each Frequency point carry out touch-control test obtain test data it
Afterwards, the touch-control accuracy rate of each Frequency point can be further calculated according to the test data of each Frequency point.
For touch-control test by the way of usinging difference, present embodiments provide the touch-controls of different each Frequency point of determination
The mode of accuracy rate.
As the possible implementation of one of which, when being tested by the way of touch-control test is clicked on using simulation, root
The touch-control accuracy rate of each Frequency point is calculated according to the test data of each Frequency point, can be included：For each frequency
Point, according to the touch-control number in corresponding test data, and deviation during touch-control test between used touch-control number is carried out, meter
Calculate the first accuracy rate component of Frequency point；According to the position of touch in corresponding test data, with being used during progress touch-control test
Position of touch between deviation, calculate the second accuracy rate component of Frequency point；To the first accuracy rate component and the second accuracy rate
Component is weighted averagely, obtains the touch-control accuracy rate of Frequency point.
It should be noted that simulation clicking operation can utilize the point touching screens such as stylus, finger by tester
Mode is realized, can also realize automatic test, the invention is not limited in this regard by writing program.Touch-control in test data
Several acquisition modes can carry out statistics acquisition by way of setting counter, it is of course also possible to use other can be counted
The mode of touch-control number is obtained, and the present invention is not also restricted to this.
By the way of simulation is clicked on, because the number of touch-control and the position of touch-control can be pre-set, thus can be accurate
Used touch-control number and used position of touch when really knowing touch-control test, so as to according to each frequency of collection
The touch-control number and position of touch recorded in the test data of rate point, the touch-control number recorded in test data is calculated with being used
Touch-control number between deviation, and calculate the first accuracy rate component of respective frequencies point, and calculate and recorded in test data
Position of touch and used position of touch between deviation, and calculate the second accuracy rate component of respective frequencies point.
As a kind of example, when calculating the first accuracy rate component, the touch-control recorded in test data can be first calculated
Deviation between number and used touch-control number, then calculate gained deviation and test when used touch-control number between
First ratio, difference obtained by the first ratio is subtracted as the first accuracy rate component using 1.Similarly, the second accuracy rate point is being calculated
During amount, the deviation between the position of touch recorded in test data and used position of touch can be first calculated, that is, is counted
Go out the position of touch recorded in test data the frequency points different from used position of touch, then calculate position of touch difference
Frequency points and used position of touch number between the second ratio, subtract difference obtained by the second ratio using 1 and be used as the
Two accuracy rate components.
Finally, average calculating operation is weighted to the first accuracy rate component and the second accuracy rate component that calculate gained, by institute
Obtain touch-control accuracy rate of the result as Frequency point.
By recording touch-control number and position of touch in the test data of testing touch-control, and respectively with being used during test
Touch-control number and position of touch be compared, calculate and obtain the first accuracy rate component and the second accuracy rate component, and then pass through
Weighted mean operation obtains the touch-control accuracy rate of Frequency point, it is possible to increase the computational accuracy of the touch-control accuracy rate of Frequency point.
As wherein alternatively possible implementation, tested by the way of touch-control test is not clicked on using simulation
When, due to not clicked on using simulation, then under noiseless situation, the touch-control number of each Frequency point is zero.Therefore, not using simulation
When the mode of click carries out touch-control test to Frequency point, the touch-control that is recorded in the test data that obtains when can be by judging to test
Whether number is zero, to determine whether Frequency point is disturbed by external interference source.If the touch-control number in test data is not
Zero, then it is assumed that Frequency point is disturbed by external interference source, and determines that the touch-control accuracy rate of Frequency point is less than accuracy rate threshold value.
Not when being tested by the way of simulation is clicked on Frequency point, by the touch-control number in test data not
It is that the zero direct touch-control accuracy rate for determining Frequency point is less than accuracy rate threshold value, fast and easy, is advantageous to improve debugging efficiency, reduces
Debugging cost.
Step 202, by frequency range to be debugged, touch-control accuracy rate is less than the Frequency point of accuracy rate threshold value, is defined as abnormal frequency
Rate point.
It should be noted that accuracy rate threshold value can by tester rule of thumb or actual demand is set, such as,
Requirement to debugging accuracy rate is higher, can set accuracy rate threshold value bigger.The present invention takes to the specific of accuracy rate threshold value
Value is not construed as limiting.
, can be further by touch-control accuracy rate and pre- after calculating the touch-control accuracy rate for obtaining Frequency point in the present embodiment
The accuracy rate threshold value first set is compared, and Frequency point of the touch-control accuracy rate less than accuracy rate threshold value is defined as into abnormal frequency
Point.
Alternatively, when touch-control is tested not in the case of touch-control test is carried out to Frequency point by the way of simulation is clicked on,
Due to directly the touch-control accuracy rate for the Frequency point that touch-control number is not zero in test data can be defined as being less than under which
Accuracy rate threshold value, thus Frequency point corresponding to touch-control number directly can be defined as abnormal frequency point during use which.
Step 203, from frequency range to be debugged, abnormal frequency point is excluded, determines target frequency point.
, can be further from frequency range to be debugged determined by exclusion after determining abnormal frequency point in the present embodiment
Abnormal frequency point, using remaining Frequency point as target frequency point.
The working frequency adjustment method of the touch-screen of the present embodiment, by being calculated according to the test data of each Frequency point
The touch-control accuracy rate of each Frequency point, Frequency point of the touch-control accuracy rate in frequency range to be debugged higher than accuracy rate threshold value is defined as
Abnormal frequency point, abnormal frequency point is excluded from frequency range to be debugged, and then determine target frequency point, can avoided extraneous dry
Interference of the source to Frequency point is disturbed, reaches jamproof purpose.
