In life now, as the communication technology is more and more flourishing, more and more come real by the way of signal transmission
The transmission of existing data.By taking the technical field of DTV as an example, as LCD TV size is increasing, resolution is increasingly
Height, the data for needing to transmit are also increasing, and differential signal just obtains extensively as the transport protocol of high speed a kind of in data-signal
It is general universal.But in data-signal during actual transmissions, due to transmitting the inconsistency of cabling characteristic impedance, data-signal
Reflex can be encountered during transmission, and it is folded that reflected data-signal carries out signal with initial clock signal again
Add, causes the waveform of the clock signal actually obtained uneven phenomenon occur, if at this moment again directly according to the clock signal
Go the data of extraction data-signal, it is possible to the data of mistake can be extracted.
As shown in figure 3, top is the waveform of data-signal in figure, lower section is the waveform that clock signal generates.When clock is believed
When number being reflected influence, the shape of clock signal changes, such as the B point of the A point for occurring being recessed in Fig. 3 and respective protrusions,
When the current potential of A point is less than certain value, when signal identification, it is easy the current potential of the point being considered as negative value, at this point, the shape on the right side of A point
The data in data-signal are grabbed at rising edge, and then according to the rising edge of generation, abnormal crawl phenomenon occurs, data is caused to be grabbed
Take mistake.Likewise, forming failing edge on the right side of B point, with the data in this failing edge crawl data-signal, lead to data
Grab mistake.When receiving end receives the data of mistake, data is be easy to cause to show the appearance of exception or noise.
In order to avoid the phenomenon that above-mentioned abnormal crawl data occurs, the application provides a kind of transmission method of data, is examining
Measure that there are when data transmission, start to obtain the corresponding clock signal of data-signal.And determine the clock signal in time interval
Current potential, wherein current potential direction of the clock signal within half of clock cycle is identical, thus the clock cycle be half of clock
Period, therefore, the time interval is a period of time in half of clock cycle.It is added at data driver (Data Driver)
There is current potential judging unit, after data driver gets clock signal, clock signal can be obtained by current potential judging unit
The corresponding current potential of various time points.
Further, after the zero volt time point delay certain predetermined duration when the current potential for detecting clock signal is 0V,
Start the current potential of the clock signal in time interval described in real-time detection.As shown in figure 4, detection clock signal is between the Δ t time
Every interior current potential.It is easily understood that clock signal drops after being increased with output amplitude current potential in the half period of clock signal
It is low be in sinusoidal, begin to ramp up and approach decline terminate in deposit within a certain period of time, current potential lesser time point, can
Preset threshold can be lower than, therefore, the time interval of acquisition clock signal current potential is the partial time period in half period in real time,
I.e. deduct half period start after a period of time and half period terminate before a period of time.It avoids to causing abnormal to grab point
The erroneous judgement of (C point) increases output amplitude, when increasing on foot when output amplitude can satisfy the normal data crawl of clock signal
The workload of clock signal sending end.
Step S30 increases the output amplitude of the clock signal when the current potential of acquisition is lower than preset threshold.
When being less than preset threshold there are current potential in detecting the time interval clock signal, show that the current potential is corresponding
Time point negative voltage may be mistakenly considered by signal receiving end, be easy to produce rising edge or failing edge at this time point, into
And using rising edge or failing edge as data grabber point.For the data grabber point for avoiding the formation of mistake, it is lower than getting current potential
When preset threshold, the too low signal of feedback magnitude to clock signal transmitting terminal (for example, Timing driver chip), for clock letter
Number transmitting terminal increase clock signal output amplitude.After the output amplitude of clock signal obtains increase, clock signal is symbol
New output amplitude is closed, current potential is enhanced lower than the time point corresponding current potential of preset threshold, thus near this time point not
It will appear rising edge or failing edge, efficiently avoid the mistake crawl of data.Wherein, preset threshold is the critical of signal judgement
Value, usually desirable 0-0.3V.
In addition, data-signal is transmitted with sinusoidal waveform, the current potential in signal wave at various time points it is positive and negative be it is opposite,
Above-mentioned can be considered illustrates by taking first half cycle as an example.When being the later half period when detection, judge it is contrary, i.e., when getting electricity
When position is higher than preset threshold, increase the output amplitude of clock signal, preset threshold is negative value at this time；Either, second half is changed
The current potential direction of phase after taking opposite number to become positive value the current potential in later half period, then carries out whether current potential is lower than preset threshold
Judgement.
As shown in figure 4, the current potential in detection clock signal in the Δ t period, when the current potential for detecting C point is less than 0.3V
When, the feedback information for increasing amplitude is fed back to clock signal output terminal, clock signal output terminal increases the defeated of subsequent clock signal
Amplitude out forms the corresponding clock signal wave of solid line (dotted line is the clock signal wave before output amplitude increases) below, at this point, with
The C point period current potential of corresponding D point is improved, and receives the clock signal after amplitude increases in data driver, correct to know
Other high level or low level, D point will not nearby generate the rising edge or failing edge of erroneous judgement again, avoid the mistake crawl of data.
Further, the initial magnitude of the initial clock signal sent due to each clock signal transmitting terminal is different, so
When the output amplitude to clock signal increases, initial magnitude is first obtained, determines target amplitude further according to initial magnitude, when by this
The output amplitude of clock signal increases to target amplitude.For example, show when initial magnitude is 0.5V using 0.5V as output amplitude,
Point is grabbed in the presence of abnormal, it is determined that target amplitude 0.8, i.e., it is subsequent to generate and send clock signal by output amplitude of 0.8V；
If initial magnitude is 0.4V, target amplitude can be 0.6V.The increasing degree of specific amplitude is determined by experiment, is only for example herein
Explanation.
In the present embodiment, when detecting the presence of data transmission, start to obtain the corresponding clock signal of data-signal.And
Determine the current potential of clock signal time interval Nei, wherein less than half clock cycle of the time interval.It is described detecting
When being less than preset threshold there are current potential in time interval clock signal, transmission of the too low signal of feedback magnitude to clock signal
It holds (for example, Timing driver chip), so that the transmitting terminal of clock signal increases the output amplitude of clock signal.In clock signal
After output amplitude obtains increase, clock signal is to meet new output amplitude, and current potential is corresponding lower than the time point of preset threshold
Current potential is enhanced, to be not in rising edge or failing edge near this time point, the mistake for efficiently avoiding data is grabbed
It takes.
Further, referring to Fig. 5, another embodiment of the transmission method of the application data is based on an above-mentioned embodiment, described
After step S10, further includes:
Step S40 obtains the clock cycle of the clock signal.
It is provided with frequency judging unit in data driver (Data Driver), can be obtained by frequency judging unit
Since the period is reciprocal each other with frequency, therefore clock signal can be obtained according to the frequency got in the frequency for taking clock signal
Clock cycle.
In addition, clock letter can be got by the current potential judging unit being arranged in data driver (Data Driver)
Current potential is the zero volt time point of 0V in number, and the time interval in clock signal between two adjacent zero volt time points is half of clock
Period, therefore, the clock cycle can be obtained according to two adjacent zero volt time points.Clock letter can also be obtained by other means
Number clock cycle, will no longer repeat one by one again.
In the present embodiment, after getting clock signal, the clock cycle is obtained according to clock signal, in order to subsequent
Described in the presence or absence of the judgement time interval of the abnormal crawl of data, that is, being determined in clock cycle determining detection clock signal
Time interval helps to disappear to data exception crawl point to obtain the current potential of the clock signal in real time in the time interval
It removes, avoids data acquisition mistake.
Further, referring to Fig. 6, another embodiment of the transmission method of the application data is based on above-mentioned each embodiment, institute
After stating step S30, further includes:
Step S50, the clock signal after being increased according to output amplitude obtain the data of the data-signal.
Although the output amplitude of clock signal is increased, the period of the clock signal and frequency do not receive and change
Become, therefore the clock signal after being increased according to output amplitude still can effectively grab the corresponding data letter of the clock signal
Valid data in number.And clock signal, after the increase of output amplitude, some previously existing abnormal crawl points are gone
It removes, therefore, the data in data-signal can be accurately grabbed according to this clock signal, improve the accuracy of data grabber.
By amplitude increase after clock signal grab data when, obtain the clock signal rising edge and/or under
Edge is dropped, determines time point corresponding with the rising edge or the failing edge in the corresponding data-signal, and when determining
Between data in data-signal are grabbed at point.
In the present embodiment, when the clock signal after increasing by amplitude grabs data, the clock signal is obtained
Rising edge and/or failing edge determine time point corresponding with the rising edge or the failing edge in the corresponding data-signal,
And the data in data-signal are grabbed at determining time point.It, should although the output amplitude of clock signal is increased
The period of clock signal and frequency do not receive change, therefore the clock signal after being increased according to output amplitude still can
Effectively grab the valid data in the corresponding data-signal of the clock signal.And clock signal is after the increase of output amplitude,
Some previously existing abnormal crawl points are removed, therefore, the number in data-signal can be accurately grabbed according to this clock signal
According to improving the accuracy of data grabber.
In addition, the embodiment of the present application also proposes a kind of transmission method of data, when detecting the presence of data transmission, start
The corresponding clock signal of data-signal is obtained, and obtains the clock cycle of the clock signal.Due to half of complete clock week
Phase inner potential direction is identical, so the current potential of clock signal is obtained in real time, when there are current potentials to be less than preset threshold in clock signal
When, show that the current potential corresponding time point may be mistakenly considered negative voltage by signal receiving end, is easy to produce at this time point
Rising edge or failing edge, and then using rising edge or failing edge as data grabber point.To avoid the formation of wrong data grabber point,
When getting current potential lower than preset threshold, the too low signal of feedback magnitude to clock signal transmitting terminal (for example, Timing driver
Chip), so that the transmitting terminal of clock signal increases the output amplitude of clock signal.Default amplitude is obtained, by the defeated of clock signal
Amplitude increases to the default amplitude out.After the output amplitude of clock signal obtains increase, clock signal is to meet new output
Amplitude, current potential are enhanced lower than the time point corresponding current potential of preset threshold, to be not in rise near this time point
Edge or failing edge efficiently avoid the mistake crawl of data.
Further, the acquisition time section to make the current potential of clock signal is complete half of clock cycle, when detection
The current potential of clock signal is the zero volt time point of zero volt, and is enlightenment time point with the zero volt time point, obtains half of clock week
The current potential of phase clock signal
