It as shown in Figure 3a, include multiple subframes in a frame period of touch control display apparatus, each subframe is divided into multiple Display interval DP1 to DPq, multiple touch section TP1 to TPq, wherein multiple display intervals are distributed between multiple touch sections In gap.Touch display unit carries out display driving using time-sharing format and touches driving.When carrying out display scanning, pause Touch detection scanning；When carrying out touching scanning, pause display scanning.Section in different times, alternately show data and The processing of touch data.

Section TP1 is being touched into TPq, display drive apparatus stops scanning, touches driving device and starts to work.For example, In the 1st touch section TP1, touches driving device and effective pumping signal is applied to the 1st article and kth bar driving line, so that The inductance capacitance C of 1st column and kth column_TIt is activated, the 1st to the nth line of induction can be coupled with the sense of the 1st column and kth column Answer capacitor C_TInductive signal, thus know the 1st column and kth column inductance capacitance C_TWhether position occurs touch operation.It is similar , in the 2nd touch section TP2, touches driving device and effective pumping signal is applied to the 2nd article and+1 bar of driving line of kth, So that the inductance capacitance C that the 2nd column and kth+1 arrange_TExcitation is received, the 1st to the nth line of induction can be coupled with the 2nd column and kth The inductance capacitance C of+1 column_TInductive signal, thus know the 2nd column and+1 column inductance capacitance position of kth whether touch Operation.And so on, it can judge whether entire all the points block occurs touch operation.

In display interval DP1 into DPq, touches driving device and stop scanning, display drive apparatus is started to work.The 1st In a display interval DP1, display drive apparatus can apply effective gate drive signal to the 1st to a+1 articles grid line, so that 1st row to a+1 row pixel unit can be shown according to the gray scale voltage that source level drive module provides.Similarly, aobvious the 2nd Showing in the DP2 of section, display drive apparatus can apply effective gate drive signal to (a+2) to 2 (a+1) articles of grid line, (a+2) row is shown to the 2nd (a+1) row pixel unit according to the gray scale voltage that source level drive module provides. And so on, it can be realized the display scanning of all grid lines.Wherein, a is natural number, and specific value can be according to grid line The number of sum and the display interval divided determines.

In the last one display interval of each subframe, display drive apparatus successively applies remaining grid line effectively Grid line driving signal so that whole grid lines can be successively strobed to realize a frame picture during a subframe Display.

The above are traditional driving methods, between multiple continuous subframes, point of each display interval in each subframe Cut that mode is identical, the sequence and quantity of scanned grid line are all the same in each display interval.Therefore, in each of different subframes The position (i.e. serial number) for the last item grid line being scanned in a display interval is all the same, occurs and each display interval The problem of corresponding horizontal line of the last item grid line (H line), causes to show that quality is deteriorated.

In order to overcome the above problem, the partitioning scheme of the display interval of the different subframes in the same frame period can be set It is different.For example, starting the position of first grid line of scanning in first display interval of different subframes or being scanned Grid line quantity can be according to the variation of frame period generating period, complementally, the last one display interval of different subframes In, " line shifting " has occurred, and this method can disappear in variation of the grid line quantity being scanned according to frame period generating period Except horizontal line visible in continuous subframes.

Fig. 3 b shows the driving method schematic diagram of touch control display apparatus in the related technology.Fig. 3 c shows different in the related technology The schematic diagram of the corresponding line of induction of the last item grid line in display interval.

As shown in Figure 3b, in this embodiment, each subframe includes 10 display interval DP1 to DP10.In each subframe The sequence that period scans each grid line is identical, still, between multiple continuous subframes in a frame period, each subframe The first display interval DP1 in the quantity of grid line that is scanned it is different, such as be decremented to 117 grid from 132 grid lines Polar curve.The quantity for the grid line that second display interval DP2 is scanned into the 9th display interval DP9 is constant, and for example, 132 Grid line.Therefore tenth display interval DP10, is scanned for driving remaining grid line in the tenth display interval DP10 The grid line quantity being scanned in grid line quantity and the first display interval DP1 is complementary, i.e., is incremented to 107 from 92 grid lines Grid line.The scanning to 1280 grid lines is completed during each subframe, to obtain the complete image frame of a frame.

Therefore, between each continuous subframe in each frame period, i-th of display interval in each subframe is corresponding Last grid line it is different, wherein i indicates that the serial number of display interval, i are natural number, and i is less than or equal to 10, that is, in each display At the end of section, the serial number for the last item grid line being scanned during the display interval is according to frame period generating period Variation (i.e. " line shifting ').For example, as described above, the corresponding last grid of the first display interval DP1 to the tenth display interval DP10 Line is followed successively by the 132nd article of grid line to the 117th article of grid line.

In touch display unit, there is corresponding relationship, which includes: for a plurality of grid line and a plurality of line of induction The number of a plurality of grid line is the integral multiple of a plurality of line of induction number, and a plurality of grid line is arranged in parallel with a plurality of line of induction, every The position of grid line corresponds to a corresponding line of induction.For example, touch display unit is equipped with 1280 grids being parallel to each other Line and 32 lines of induction, then being provided with 1 line of induction in the top of every 40 grid lines.

Therefore, between multiple continuous subframes in a frame period, according to the corresponding last grid of each display interval The serial number of polar curve can calculate the serial number of the corresponding line of induction (being denoted as the related line of induction).However, in the same frame period The corresponding line of induction of last grid line of the continuous subframe of continuous any two, the scanning of i-th of display interval may not be identical. For example, as shown in Figure 3c, in the diagram frame period, the first display interval DP1 of the 11st subframe (number 10) is corresponding last Grid line is the 122nd article of grid line, and the serial number of the corresponding related line of induction of the 122nd article of grid line is 4, and the serial number is by (122- 1) value that rounds up/40 obtains, and the corresponding last grid line of the first display interval DP1 of the 12nd subframe (number 11) is The serial number of 121st article of grid line, the corresponding related line of induction of the 121st article of grid line is (121-1)/40=3, therefore the 11st is sub The corresponding related line of induction of corresponding last grid line is different at the end of the first display interval DP1 in frame and the 12nd subframe, hair Variation has been given birth to, has caused second in the 11st subframe and the 12nd subframe to touch and corresponds to the line of induction (the 3rd article of line of induction and the in section 4 lines of induction) on the acquisition of inductive signal had interference tolerate threshold beyond noise so that existing on corresponding inductive signal The noise of value.

According to the above analysis, can solve horizontal line (H line) with upper type causes to show the problem of quality is deteriorated, but It is original capacitance when grid line stops and is not parked in certain line of induction, because the load of display screen is different, corresponding to the line of induction at this Value is also different, introduces oblique line noise, influences touch detection.

In order to solve the above-mentioned technical problem, the present disclosure proposes a kind of data processing methods of touch control display apparatus, inhibit Influence of the noise that grid line generates on the line of induction to touch detection.

Fig. 4 a shows the flow chart of the data processing method of the touch control display apparatus according to one embodiment of the disclosure.This method It can be applied in all kinds of consumption electronic products, wherein all kinds of consumption electronic products can be mobile terminal, PC (PersonalComputer, personal computer) or tablet computer etc..Touch control display apparatus can be aobvious for optical touch control Show that panel, electric resistance type touch control display panel, electromagnetic touch-control display panel, sound wave type touch-control display panel or capacitance touching control are aobvious Show panel etc..

As shown in fig. 4 a, this method may include:

Step S11 is moved for each subframe according to the corresponding relationship of frame period, grid line and the line of induction and line Number, determines the data position to be processed in the subframe；

Wherein, the frame period includes multiple subframes, and the line, which moves number, indicates the of the scanning of every two adjacent sub-frame The item number of the grid line differed between one grid line.

Step S12 obtains the first numerical value at data position to be processed for each data position to be processed；

Step S13, when the difference at current time and a upper study moment is more than or equal to learning cycle, according to a upper study All first numerical value in moment to current time at the data position to be processed calculate the second of data position to be processed Numerical value；

Step S14 is adjusted corresponding data position to be processed using the second value.

In one possible implementation, data position to be processed can be noise compensation position, described first Numerical value can be noise figure, and the second value can be noise compensation value.

Method shown in Fig. 4 a is by periodically learning the noise figure at noise compensation position, to obtain noise compensation Value, so that noise compensation value can effectively eliminate the oblique line noise of touch display unit, significantly improve closer to true noise The signal-to-noise ratio of touch detection.It should be noted that data position to be processed, the first numerical value and second value are not limited to above-mentioned show Example, the data processing method of the disclosure can also be applied to touch control display apparatus and move other numbers under the scene that mode scans using line According to processing, for example, display driving in grayscale signal processing etc..

Hereinafter the data in each step will be substituted respectively with noise compensation position, noise figure, noise compensation value to wait locating For managing position, the first numerical value, second value, the data processing method of the touch control display apparatus of the disclosure is introduced.

Wherein, touch control display apparatus may include: a plurality of grid line, a plurality of driving line and a plurality of line of induction.In touch-control In display device, the line of induction for showing the grid line of driving and for touch detection can be located at different metal layers. The grid line for showing driving and the line of induction for touch detection can be arranged in parallel each other, each grid Line can correspond to a line of induction, and a line of induction can correspond to a plurality of grid line.For example, the resolution ratio of touch control display apparatus For 1280*720, including 1280 grid lines, 32 lines of induction, wherein the line of induction is arranged in parallel with grid line, each Grid line is corresponding with a wherein line of induction, and a line of induction is corresponding with 40 grid lines.For example, first line of induction Corresponding 2nd to the 41st article of grid line, Article 2 inductive line pair answer the 42nd to the 81st article of grid line etc..

It include multiple subframes in one frame period of touch control display apparatus, each subframe can be divided into multiple viewing areas Between and multiple touch sections, multiple display intervals be distributed in multiple gaps for touching sections, can will be in a frame period First subframe is determined as benchmark subframe.

In one possible implementation, step S11 may include:

If in the subframe, corresponding first line of induction of last grid line and benchmark of the scanning of i-th of display interval Corresponding second line of induction of last grid line that i-th of display interval scans in frame is different, it is determined that first line of induction and with Corresponding second line of induction of first line of induction is the data position to be processed in the subframe, i.e. noise compensation position.Wherein, i For natural number and i is less than the sum of multiple display intervals.

According to analysis above it is found that due between multiple continuous subframes in a frame period there are line shifting, because This, in a subframe and benchmark subframe, the corresponding line of induction of last grid line of i-th of display interval scanning may not phase Together, oblique line noise is thus introduced, these lines of induction, that is, noise compensation position.

Fig. 5 shows the driving method schematic diagram of the touch control display apparatus of the embodiment according to the disclosure.Fig. 6 shows basis The schematic diagram of the line of induction corresponding to last grid line in the different display intervals of one embodiment of the disclosure.

As shown in figure 5, by taking resolution ratio is the touch control display apparatus of 1280*720, STM-16 as an example, touch control display apparatus One frame period may include 16 subframes, serial number are as follows: 0~15；Each subframe can be divided into 20 display intervals, serial number Are as follows: 1~20；As shown in fig. 6, each subframe can be divided into 18 touch sections, serial number 1~18.In addition, each subframe There can also be different division modes as needed, for example, each subframe can also be divided into 10 display intervals, 8 Section etc. is touched, be specifically divided into multiple display intervals as each subframe and touches section, is according to noise compensation value Computational accuracy is configured, and is not limited one by one herein.

First subframe of serial number 0 in Fig. 5 can be determined as the benchmark subframe in the frame period.Touch display unit Other subframes in the frame period can also be selected as benchmark subframe, as long as being convenient for the calculating of noise compensation value, herein It does not limit one by one.

Below by taking first subframe in a frame period is benchmark subframe as an example, determining noise compensation position is explained further The mode set.

As shown in figure 5, scanning first is pre- in second display interval to penultimate display interval of each subframe The grid line of fixed number amount.Wherein, the quantity of the grid line of the first predetermined quantity can according to the resolution ratio of touch control display apparatus with And the quantity of the display interval divided determines, example as shown in Figure 5, the first predetermined quantity can be 1280/20=66.

The example that line moves can be between multiple continuous subframes in each frame period, to change The quantity of the grid line of first display interval and the scanning of the last one display interval in different subframes.The above-mentioned first grid Polar curve can indicate first display interval or the grid line of the last one display interval scanning in subframe.Wherein, line moves number It can be 1, can also be arranged according to the actual needs, the disclosure is not construed as limiting this.

Between multiple continuous subframes in each frame period, change different sons by the way of line shifting The quantity of the grid line of first display interval and the scanning of the last one display interval in frame, is specifically as follows: one corresponding Between continuous subframe in the frame period, the quantity of the grid line of first display interval scanning can be incremented by or successively decrease, phase It answers, the quantity of the grid line of the last one display interval scanning can successively decrease or be incremented by.The disclosure to be incremented by or successively decrease Quantity be not construed as limiting, for example, the quantity of grid line of first display interval scanning can successively decrease 1.In this way, The corresponding line of induction of last grid line that can change each display interval scanning, eliminates the visible level in continuous subframes Line.

As shown in figure 5, each number represents the last grid line of the scanning of each display interval in a subframe in figure Position (serial number), for example, the 66 of the first row first row for the first subframe (serial number 0) the scanning of first display interval most The position (serial number) of post tensioned unbonded prestressed concrete line, first subframe scan 66 grid lines in first display interval.The of first subframe Two to the 19th display intervals scan the grid line of identical quantity (such as 66 articles), the last one display interval (serial number 20) Scan 26 grid lines.The 65 of second row first row are that second subframe (serial number 1) is scanned most in first display interval The position (serial number) of post tensioned unbonded prestressed concrete line, second subframe scan 65 grid lines in first display interval.The of second subframe Two to the 19th display intervals scan the grid line of identical quantity (such as 66 articles), the last one display interval (serial number 20) Scan 27 grid lines.And so on, different subframes by line move in a manner of successively decrease first display interval scanning grid line number Amount, the first display interval 66 grid lines of scanning of first subframe (serial number 0), the first of second subframe (serial number 1) Display interval scans 65 grid lines, and similarly, the first display interval of the last one subframe (serial number 15) scans 51 grids Line.Due in each subframe complete 1280 grid lines scanning, it is complementary, first subframe to the last one subframe it is last One display interval successively scans 26~41 grid lines.It is scanned most in second to the 19th display interval of different subframes The serial number of post tensioned unbonded prestressed concrete line is also successively decreased.

The above scanning mode is only an example of the disclosure, does not limit the disclosure in any way.

The driving line of the second predetermined quantity is driven in each touch section, and the sense of access should be believed on a plurality of line of induction Number.

Each section that touches can drive the driving line of a predetermined quantity (such as 2), the excitation connected on the driving line Capacitor C_TIt is activated, the 1st to the nth line of induction can be received from the capacitor C being activated_TInductive signal.As shown in fig. 6, One frame period may include 18 touch sections.First touch section can drive the 1st article and the 18th bar driving line, with 1 article of driving capacitor C for driving line to connect with the 18th article_TIt is activated, touch sensible module can receive the 1st to the 32nd article respectively The inductive signal for the capacitor on position that the line of induction drives line to intersect with the 1st article and the 18th article.

Section and the setting of display interval interval are touched as described above, carry out display driving and touch to drive using time-sharing format It is dynamic.

For i-th of display interval in a subframe, induction corresponding to the last grid line that display interval i is scanned The position of line is compared with the position of the line of induction corresponding to the last grid line of the display interval i scanning in benchmark subframe, It can determine first line of induction and second line of induction.When position difference, i-th of display interval of the subframe is scanned last The last grid line phase that the line of induction corresponding to grid line is scanned as i-th of display interval in first line of induction, benchmark subframe For the corresponding line of induction as second line of induction, first line of induction and second line of induction are a noise compensation in the subframe Position.The position of the line of induction corresponding to last grid line is different in identical display interval, receives on the corresponding line of induction Inductive signal is interfered, and leads on the line of induction that there are biggish noises for collected data.

As shown in fig. 6, the serial number 1-16 in left side represents the serial number of subframe, the serial number of upside represents the serial number of display interval, Each number represents the position of the line of induction corresponding to the last grid line of the scanning of each display interval in a subframe in figure Set (serial number).Still it is illustrated by taking 32 lines of induction and 1280 grid lines above as an example, i.e., every 1 incudes and 40 Grid line is corresponding, and the 1st article of inductive line pair answers the 2nd to the 41st article of grid line, can calculate each subframe in different displays The position of the line of induction corresponding to the last grid line of section scanning.In conjunction with shown in Fig. 5 and Fig. 6, second of the first subframe is aobvious The last grid line for showing section scanning is 132, then the position of the line of induction corresponding to this grid line is (132-1)/40 upward Being rounded is 4, that is, corresponds to the Article 4 line of induction, as shown in fig. 6, the line of induction corresponding to second display interval of the first subframe Position is 4；The last grid line of second display interval scanning of 11st subframe is 122, then corresponding to this grid line It is 4 that the position of the line of induction rounds up for (122-1)/40, that is, corresponds to the Article 4 line of induction, as shown in fig. 6, the 11st subframe The position of the line of induction corresponding to second display interval is 4；What is scanned in second display interval of the 12nd subframe is last One grid line is 121, then it is 3 that the position of the line of induction corresponding to this grid line, which is (121-1)/40, that is, corresponds to Article 3 The line of induction, as shown in fig. 6, the position of the line of induction corresponding to second display interval of the 12nd subframe is 3, and so on, The position of the line of induction corresponding to the last grid line of each display interval scanning of each subframe can be calculated.Such as Fig. 6 institute Show, the position of the line of induction corresponding to the last grid line of second display interval scanning in the 11st subframe and the 12nd subframe Set different (the how corresponding lines of induction of last grid line and first of second display interval scanning in namely the 12nd subframe Second display interval difference in subframe) so that being touched in section in the third in the 11st subframe and the 12nd subframe The inductive signal received on the line of induction is interfered, and leads on the line of induction that there are biggish noises for collected data.

For the same frame period, if any one subframe and benchmark subframe scan most in i-th of display interval The position of the line of induction corresponding to post tensioned unbonded prestressed concrete line is different, then the corresponding induction of the last grid line scanned in i-th of display interval Inductive signal on line is interfered, and leading on the line of induction collected data, there are biggish noises, these are all that noise is mended Position is repaid, needs to compensate, such as is currently the 8th subframe, the then last grid scanned in the 8th, 11,14,17 display interval The position of the line of induction corresponding to line is different from reference frame (the first subframe), needs to carry out noise compensation.

Fig. 4 b shows the flow chart of the method for the step S12 according to one embodiment of the disclosure, as shown in Figure 4 b, one kind can In the implementation of energy, step S12 may include:

Step S121 is touched in section in compensation, obtain first capacitor value of first line of induction in the subframe and The second capacitance in the reference frame obtains third capacitance of second line of induction in the subframe and described The 4th capacitance in reference frame；

Wherein, it is the adjacent next touch section of i-th of display interval that the compensation, which touches section, or is and i-th The touch section that the adjacent next touch section of a display interval is scanned simultaneously.

Fig. 7 shows the noise compensation position distribution schematic diagram of the touch control display apparatus of the embodiment according to the disclosure.Fig. 7 In, the 1-31 (not showing 32) that the leftmost side one arranges represents the serial number of the line of induction, and the 1-18 of one row of upside, which is represented, touches section Serial number.

In conjunction with shown in Fig. 6 and Fig. 7, in the last grid line corresponding that second display interval of the 12nd subframe scans One line of induction is 3, and reference frame (the first subframe) is in the corresponding 4th article of line of induction of the last grid line that second display interval scans For second line of induction.As shown in fig. 7, first line of induction 3 and second line of induction 4 touch to go out on section in the third of the 12nd subframe Existing noise.

Touch control display apparatus uses H mode, and H will do it touch-control scanning twice in the mode next frame period.As shown in fig. 7, Touch control display apparatus may include 18 touch sections.When touching scanning for the first time, the first, the tenth Petting Area can be scanned simultaneously Between；When second of touch scanning, the second, the 11st touch section can be scanned simultaneously；It, can be simultaneously when third time touches scanning Scan third, the 12nd touch section etc..As shown in fig. 7, first line of induction 3 and second line of induction 4 touch section the 12nd On also there is noise.For another example, as shown in fig. 6, the last grid line in the 5th display interval scanning of the tenth subframe is corresponding First line of induction be 9, reference frame (the first subframe) the last grid line that the 5th display interval scans it is corresponding 8th article sense Answering line is second line of induction.As shown in fig. 7, first line of induction 9 and second line of induction 8 touch section, the 15th the 6th respectively It touches on section and noise, etc. occurs.And it can be with flexible setting, such as about the touch-control scanning sequency of touch control display apparatus When primary touch scanning, the first, the 9th touch section or the first, the 18th touch section etc. can also be scanned simultaneously, herein It does not limit one by one.Therefore, compensation touches section and can sweep simultaneously for the next touch section adjacent with i-th of display interval The touch section retouched.

Step S122 calculates the difference of the first capacitor value and the second capacitance as on first line of induction One noise figure.

Step S123 calculates the difference of the third capacitance and the 4th capacitance as on second line of induction Two noise figures.

For touching section as compensation using next touch section adjacent with i-th of display interval, Fig. 6 is still combined It is illustrated with Fig. 7, corresponding first line of induction of last grid line scanned in second display interval of the 12nd subframe It is 3, grid line is parked in next touch section (third touches in section) of second display interval, passes through capacitance detecting instrument (such as digital electric bridge etc.) can obtain first capacitor value C1 on first line of induction 3 at this time and in reference frame it is corresponding Compensation touches the second capacitance C2 in section (third touch section) on first line of induction 3, by first capacitor value C1 and second The difference of capacitance C2 the first noise figure DIF1 as first line of induction, i.e. DIF1=C1-C2.

Still it for touching section as compensation using next touch section adjacent with i-th of display interval, and combines Fig. 6 and Fig. 7 are illustrated, and can be obtained in the 12nd subframe by capacitance detecting instrument (such as digital electric bridge etc.), grid line The third capacitor on second line of induction 4 when being parked in next touch section (third touches in section) of second display interval Value C3 and the 4th capacitor in reference frame in compensation touch section (third touch section) accordingly on second line of induction 4 Value C4, using the difference of third capacitance C3 and the 4th capacitance C4 as the second noise figure DIF2 of second line of induction, i.e., DIF2=C3-C4.

As shown in fig. 6, with third touch section, for the 3rd article of line of induction, the 4th article of line of induction, (the 3rd article of first line of induction The line of induction) the 12nd subframe capacitance be 50, reference frame capacitance be 10；First noise figure is the electricity of the 12nd frame The capacitance 10 that capacitance 50 subtracts reference frame is equal to 40；Second line of induction (the 4th article of line of induction) is in the capacitance of the 12nd subframe It is 10, is 50 in the capacitance of reference frame, the second noise figure is that the capacitance 10 of present frame subtracts capacitance 50 of reference frame etc. In -40.Or, it is 50 equal to -40 that the capacitance that the first noise figure is benchmark frame, which is 10 capacitances for subtracting present frame, the second noise Value be the capacitance of benchmark frame be 50 subtract present frame capacitances be 10 be equal to 40.Similarly, all first senses can be calculated Answer the first noise figure and the second noise figure of line and second line of induction.

Step S124, according to the first noise figure and second on first line of induction corresponding with data position to be processed The second noise figure on the line of induction obtains the first numerical value at data position to be processed.

Illustratively, felt according to the first noise figure and second on first line of induction corresponding with the noise compensation position The second noise figure on line is answered, the noise figure at the noise compensation position is obtained.

In one possible implementation, it if first noise figure and the second noise figure meet first condition, counts The mean value of the absolute value of the first noise figure and the absolute value of the second noise figure is calculated as the first number at data position to be processed Value illustratively calculates the mean value of the absolute value of the first noise figure and the absolute value of the second noise figure as the noise compensation position Set the noise figure at place.

Wherein, the first condition can be both less than touch threshold, described for first noise figure and the second noise figure The product of first noise figure and the second noise figure less than 0 and the absolute value of first noise figure and the second noise figure it is absolute The difference of value is within the scope of preset difference value.

As shown in figure 8, in current frame period, if the first noise figure and the second noise figure are both less than touch threshold, first The product of noise figure and the second noise figure exists less than the difference of the 0, absolute value of the first noise figure and the absolute value of the second noise figure Within the scope of preset difference value, then the mean value for calculating the absolute value of the first noise figure and the absolute value of the second noise figure is mended as the noise Repay the noise figure at position, i.e. mean value DIF=(| DIF1 |+| DIF2 |)/2, using mean value DIF as the noise compensation position at Noise figure.

Wherein, touch threshold can be the maximum value of touch control display apparatus noise figure in no touch.

Touch control display apparatus has been generally divided into the case where touch (such as finger touch) and no touch.When there is touch, with For finger touches, i.e., when finger is rested on first line of induction or second line of induction, the induction amount of finger can incude to first Received inductive signal interferes on line, second line of induction, and calculating noise figure can count by the induction amount of finger, calculates Noise figure inaccuracy.This programme is that noise figure is counted and calculated in the case where no touch, therefore, in current frame period It is interior, in the case that the first noise figure and the second noise figure are both less than touch threshold, calculate noise figure.Touch threshold can be 50, It can exclude touch in this way and scanning for the first time occurs as soon as the first noise figure and the second noise figure any one is greater than etc. In the touch threshold the case where, the noise spot of obvious exception can be filtered out, the precision of noise figure is improved.

The noise of touch control display apparatus is also related with environment.Such as the background environment of the display screen of touch display unit Light can also generate certain noise etc., will affect the computational accuracy of noise figure.The product of first noise figure and the second noise figure Less than 0, can imitate exclusion because of noise caused by environment, scanning for the first time occur as soon as the first noise figure and the second noise figure product The case where not less than 0, further increases and eliminates oblique line noise, improves signal-to-noise ratio.

There is also common-mode noises, such as the noise that mains charger generates, touch control display apparatus to fill for touch control display apparatus Electric appliance can discharge a large amount of noise in entire range of scanned frequencies, cause on first line of induction and second line of induction of present frame Received inductive signal is interfered.Preset difference value may range from touch control display apparatus when common-mode noise is not present, and first The range of the difference variation of the absolute value of the absolute value of noise figure and the second noise figure, preset difference value may range from -10~10. When the absolute value and the second noise figure of the first noise figure absolute value difference within the scope of preset difference value, can effectively exclude electricity The influence of noise of source charger improves the computational accuracy of noise compensation value.According to the scanning of common-mode noise and touch display unit The size of frequency further increases in such manner, it is possible to imitate exclusion common-mode noise and eliminates oblique line noise, significantly improve signal-to-noise ratio.

Certainly, first condition also can according to need other for being set as that the first noise figure and the second noise figure need to meet Condition, the disclosure are not construed as limiting this.

Still by taking such as Fig. 6 as an example, the third of the 12nd subframe touches section, for the 3rd article of line of induction, the 4th article of line of induction, First line of induction (the 3rd article of line of induction) is 40 (or -40) in the first noise figure of the 12nd subframe, is less than touch threshold 50；The Two lines of induction (the 4th article of line of induction) are -40 (or 40) in the second noise figure of the 12nd subframe, are less than touch threshold 50, and 40 with -40 product less than 0, (| -40 |-| 40 |) be equal to 0, within the scope of preset difference value, first line of induction of the 12nd subframe The first noise figure and the second noise figure of second line of induction meet above three condition, the 12nd son in current frame period It is the exhausted of the first noise figure that the compensation of frame, which touches noise figure corresponding with first line of induction and second line of induction in section, To the mean value DIF, DIF=of the absolute value of value and the second noise figure (| 40 |+| -40 |)/2=40 or DIF=(| -40 |+| 40 |)/ 2=40.

When the first noise figure and the second noise figure meet first condition, the absolute value and second for calculating the first noise figure is made an uproar The mean value of the absolute value of sound value is as the noise figure at the noise compensation position, in such manner, it is possible to effectively exclude a variety of noises, improves The precision of noise compensation value eliminates oblique line noise, significantly improves signal-to-noise ratio.

Optionally, if first noise figure and the second noise figure are unsatisfactory for first condition, the data are not calculated and wait locating The first numerical value at reason position illustratively if first noise figure and the second noise figure are unsatisfactory for first condition, is disregarded Calculate the noise figure at the noise compensation position.It may determine that whether current time and the difference at a upper study moment are more than or equal to Practise the period.After noise figure is calculated, it also may determine that whether current time and the difference at a upper study moment are more than or equal to Practise the period.Wherein, learning cycle can be with are as follows: for each noise compensation position (line of induction for generating noise), touch-control display dress It sets study noise figure and carries out the time interval of noise compensation to the oblique line noise of generation；Therefore, for each noise position, A upper study moment can be to start the study moment of learning training, that is, needle for the learning cycle of the noise compensation position At the time of end to a upper learning cycle for the noise compensation position.

If the difference at current time and a upper study moment is more than or equal to learning cycle, according to a upper study moment to currently All first numerical value in moment at the data position to be processed calculate the second value of data position to be processed, specifically may be used Using include: by the mean value of all first numerical value in a upper study moment to current time at the data position to be processed as The second value of data position to be processed.

Illustratively, if the difference at current time and a upper study moment is more than or equal to learning cycle, upper one can be learned Practise mean value the making an uproar as the noise compensation position of all noise figures in the moment to current time at the noise compensation position Sound offset.Then, corresponding noise compensation position is compensated using the noise compensation value.

The difference at current time and a upper study moment is less than learning cycle, then can continue to determine number with return step S11 According to position to be processed.

Wherein, the difference at current time and a upper study moment can be the learning time of current subframe, and learning time can To be obtained by time set (such as timer etc.).The speed and precision of noise study is related with the size of learning cycle, learns The habit period is excessive, and the speed of noise study becomes larger but the precision of noise is lower.Learning cycle is too small, and the precision of noise is high, but Noise study slows.For the speed of balances noise study and the precision of noise, learning cycle can be set as 5s, it is full The number for the generation noise that the foot position is learnt in current learning cycle is at least 20 times, that is, the noise figure learnt is extremely It is less 20.

As shown in fig. 6, section is still touched with the third of the 12nd subframe, for the 3rd article of line of induction, the 4th article of line of induction, When the position noise occurs for the first time, the first noise figure of first line of induction (the 3rd article of line of induction) in current frame period is calculated DIF1, the second noise figure DIF2 of second line of induction (the 4th article of line of induction) obtain first line of induction and in current frame period The corresponding noise figure of two lines of induction, i.e. DIF=(| DIF1 |+| DIF2 |)/2.When third touches the 3rd article of line of induction, the 4th in section When noise occurs again in the line of induction, calculates first line of induction (the 3rd line of induction) and second line of induction (the 4th line of induction) is corresponding Noise figure DIF₁。

Likewise, determining the line of induction when there is noise every time for the noise on the line of induction of other positions in Fig. 6 Corresponding noise figure.

It is 5s with learning cycle, the third of the 12nd subframe touches section, comes for the 3rd article of line of induction, the 4th article of line of induction Illustrate, when a upper study moment is 00: 00 point: 06 second, if current time is 00: 00 point: 11 second, when the study of current subframe Between be 5s, be more than or equal to learning cycle 5s.

If current time is 00: 00 point: 09 second, the learning time of current subframe was 3s, is less than learning cycle 5s, was continued It scans and determines noise compensation position and corresponding noise figure.

If current time is 00: 00:11s, the learning time of current subframe are 5s, are greater than learning cycle 5s, will be upper In one study moment to current time, the 3rd article of line of induction, all noise figures on the 4th article of line of induction mean value feel as the 3rd article Line, the noise compensation value on the 4th article of line of induction are answered, i.e. noise compensation value on the 3rd article of line of induction, the 4th article of line of induction is (DIF+ DIF₁+…DIF_n)/2。

Similarly, the corresponding noise compensation value of all noise spots in each subframe can be calculated in each learning cycle.

The variation of environment temperature can cause the semiconductor device parameter in touch control display apparatus to change, so as to cause touch-control The oblique line noise of display device deviates former fixed value and the variation that floats up and down.Environment temperature is different, the oblique line of touch control display apparatus The variation of noise is different.For adaptive temperature drift, inhibit temperature drift within minimum limit, this programme according to setting in advance Fixed learning cycle periodically calculates and updates the noise compensation value of the noise spot position of touch control display apparatus.As shown in figure 9, false If learning cycle is 5s, start timer, every 5s, timer interruption triggering touch control display apparatus calculates the noise of each subframe The noise compensation value of point.It is determined as touch control display apparatus at the time of timer interruption is triggered touch control display apparatus and currently learns week The end of phase learns the moment, calculates first line of induction and the corresponding noise of second line of induction of each subframe in current learning cycle Offset, and corresponding noise spot is compensated with newest noise compensation value.Caused by eliminating because of temperature change Noise error, further increase signal-to-noise ratio.The time of the down trigger of timer can also be set as 6s, 7s etc., herein It does not do and limits one by one.

In the above manner, periodic learning compensation noise figure, so that noise compensation value is closer to true noise, energy The oblique line noise for enough effectively eliminating touch display unit, significantly improves the signal-to-noise ratio of touch detection.

Figure 10 shows the schematic diagram of the noise compensation result of the touch control display apparatus of the embodiment according to the disclosure.

In conjunction with shown in Fig. 7 and Figure 10, by taking third touches section and the 12nd touches the noise spot in section as an example, such as Fig. 7 institute Show, it is that the 36, the 4th article of line of induction is right in third touch section institute that the 3rd article of line of induction, which touches noise figure corresponding to section in third, The noise figure answered is 35.And it is the 6, the 4th that the 3rd article of line of induction, which touches noise figure corresponding to section in third, in Figure 10, after compensation It is 12 that the line of induction, which touches noise figure corresponding to section in third,.

As shown in fig. 7, the 3rd article of line of induction noise figure corresponding to the 12nd touch section is that the 31, the 4th article of line of induction exists Noise figure corresponding to 12nd touch section is 31.And in Figure 10, the 3rd article of line of induction touches section institute the 12nd after compensation Corresponding noise figure is that the 7, the 4th article of line of induction noise figure corresponding to the 12nd touch section is 5.

As it can be seen that by the noise processing algorithm of touch display unit, using the corresponding noise of each noise spot of calculating Offset compensation, since the oblique line noise that the horizontal line of touch control display apparatus introduces is eliminated.
