Specific embodiment
Below in conjunction with attached drawing, detailed description of the preferred embodiments.It should be understood that this place is retouched
The specific embodiment stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
There is the original that grayscale erects moire repeatedly in the present inventor when the study found that display panel being shown in the prior art
Because being:
Effective control signal successively is provided to each control terminal of multi-channel gating device according to timing shown in Fig. 1, it can
Data voltage (charging) is written to corresponding sub-pixel unit by source drive unit.When two adjacent column pixel units fill
When the data voltage entered is identical, as shown in Fig. 2, when the signal on Nth row grid line Gate is open signal, in a cycle first
It charges to the 1st column sub-pixel unit R1 of Nth row, control signal wire MUXR1 receives the moment of invalid control signal, son
The pixel voltage of pixel unit R1, which couples, to be reduced；It charges then to the 2nd column sub-pixel unit G1 of Nth row, simultaneously as grid
Signal on line is open signal, the corresponding input data line of the 1st column sub-pixel unit R1 of Nth row by multi-channel gating device to this
The 1st column sub-pixel unit R1 of Nth row electric leakage, causes the gray scale voltage of the 1st column sub-pixel unit R1 of Nth row gradually to go up.According to this
Analogize, data voltage is successively written in 6 sub-pixel units, and the output end of respective multi-channel gating device is closed, rear that data electricity is written
The sub-pixel unit gray scale voltage of pressure gos up, and the time is shorter, and in turn, every row sub-pixel unit is because multi-channel gating device closes voltage
Coupling reduces, and the electrical leakage voltage rise time is different, after causing in a cycle when the sub-pixel unit charging of write-in data voltage
Between it is shorter, gray scale voltage is smaller, and it is partially dark to show as pixel, grayscale occurs in picture when display panel being caused to show and erects moire.
In addition, when data voltage is written in the sub-pixel unit to display panel, as shown in figure 3, in gate output signal
Sub-pixel unit is written between high period, by data voltage in Gata out, specifically, in the high electricity of each gate output signal
During flat, the multi-channel gating device of corresponding each sub-pixel is sequentially output high level signal, selectively by corresponding data electricity
Pressure write-in sub-pixel unit.
During above-mentioned write-in data voltage, when the gate output signal Gata out of a frame picture is high period
Between, when (for example, when MUXG2 does not reach high level) multi-channel gating device of corresponding each sub-pixel unit is not opened, since frame turns over
Turn, voltage is+5V on the data line of corresponding sub-pixel unit, and the pixel voltage in sub-pixel unit is -5V, according to data line coupling
The storage capacitance of capacitor and sub-pixel unit is closed, voltage is redistributed, the reduction of data line and corresponding sub-pixel unit,
For example, data voltage is written after Fig. 3 sub-pixel unit G2 ratio R1, therefore, effective control is received in control signal wire MUXR1
After signal processed, when the control signal wire MUXG2 of corresponding sub-pixel unit G2 receives invalid control signal, sub-pixel unit G2
And the voltage value of corresponding control signal wire MUXG2 be 2.6V or so.Therefore, the sub-pixel unit of data voltage is written afterwards
The duration of interior low-voltage is longer, the duration and corresponding data line brown time consistency, for example, in figure
The duration of low-voltage region A on G2_source so as to show as pixel partially dark for pixel unit, and then leads to display surface
Occur grayscale when plate is shown in picture and erects moire.
For these reasons, inventor considers the time interval that data voltage is written by reducing adjacent pixel unit,
It can solve the problems, such as that grayscale occur when display panel display erects moire to a certain extent.
In view of this, providing a kind of driving method of display panel as one aspect of the present invention, wherein described aobvious
Show that panel includes multiple pixel units of multiple lines and multiple rows arrangement, for pixel unit described in any a line, from first row pixel list
Member starts, and is formed as a pixel unit group per N number of pixel unit, and N is positive integer and N >=2, any pixel unit group
In, each pixel unit includes the sub-pixel unit of M different colours, and M is positive integer and M >=3, as shown in figure 5, the driving
Method includes:
Step S1, data voltage is written to multiple sub-pixel units, wherein for any pixel unit group, timing
The sub-pixel unit that upper continuous N is written into data voltage belongs to the different pixel units.
As described above, when the present invention uses the driving method including step S1 to drive the display panel, continuous N in timing
A sub-pixel unit for being written into data voltage belongs to the different pixel units, in other words, has adjusted multiple sub-pixel lists
The timing of member write-in data voltage, is not written data voltage to multiple sub-pixel units further in accordance with the timing of the prior art, specifically
It is to be understood that for two pixel units of the arbitrary neighborhood in the same pixel unit group, in a pixel list thereto
Number is written to the last one sub-pixel unit of the pixel unit after first sub-pixel unit write-in data voltage of member
Before voltage, data voltage at least is written at least one sub-pixel unit of one other pixel unit.
When data voltage is written to multiple sub-pixel units according to " timing ", two adjacent pictures can be made
The time interval of plain unit write-in data voltage shortens, and then reduces the difference of electric leakage rise time；Further, since rear open son
The time of brown is longer in pixel unit, therefore, electric to multiple sub-pixel units write-in data according to " timing "
When pressure, it is also possible that for two pixel units of arbitrary neighborhood in the same pixel unit group, the respective sub-pixel list of the two
The absolute value of the difference of the sum of time of brown reduces in member.And then improves to a certain extent, even is eliminated display
Grayscale when Display panel erects moire.
Preferably, for two pixel units of arbitrary neighborhood in the present invention, data voltage is written in the sub-pixel unit
Sequence meet following formula (1):
Wherein, eiThe serial number of data voltage is written into for i-th of sub-pixel unit in previous pixel unit；ejFor
J-th of sub-pixel unit of the latter pixel unit is written into the serial number of data voltage；i,j,eiAnd ejFor equal positive integer, and 1
≤ i≤M, 1≤j≤M, 1≤ei≤ 2M, 1≤ej≤2M；α is preset threshold, it is preferable that 0 < α≤3.
Lower mask body illustrates the principle of above-mentioned formula (1):
The present inventor is by carrying out multiple driving test discovery to display panel, when a pixel unit
When the absolute value of the difference of the sum of two adjacent pixel unit weights Total is less than or equal to 3 in group, display panel will not when showing
There is apparent grayscale and erects moire.Conversely, display panel just will appear apparent grayscale when showing erect moire.Based on above-mentioned original
Display surface can be solved as long as meeting formula (1) to the timing of multiple sub-pixel units write-in data voltage of display panel in reason
There is the problem of grayscale erects moire in plate when showing.
Specifically, referring to weight analysis table shown in Fig. 8, the corresponding numerical value of each sub-pixel unit is the sub- picture in table
Plain unit leak source voltage recovery time corresponding weight during data voltage is written, numerical value is bigger, indicates electrical leakage voltage
The rise time is longer, meanwhile, the electrical leakage voltage rise time longer order for also illustrating that the sub-pixel unit and being written into data voltage
It is more forward, that is, serial number eiAnd ejSmaller, vice versa.
With the 9th row data instance in Fig. 7, the weight of sub-pixel unit R1, G1, B1, R2, G2, B2 is respectively 6,4,2,5,
3,1, physical significance is: sub-pixel unit R1 the 1st is written into data voltage, and sub-pixel unit R2 the 2nd is written into number
According to voltage, sub-pixel unit G1 the 3rd is written into data voltage, and sub-pixel unit G2 the 4th is written into data voltage, sub-pixel
Unit B 1 the 5th is written into data voltage, and sub-pixel unit B2 the 6th is written into data voltage.
In other words, for above-mentioned two adjacent pixel units, in previous pixel unit, sub-pixel unit R1 is written into
The serial number e of data voltage1=1, sub-pixel unit R2 are written into the serial number e of data voltage2=2, sub-pixel unit G1 is written into number
According to the serial number e of voltage3=3；In the latter pixel unit, sub-pixel unit G2 is written into the serial number e of data voltage4=4, sub- picture
Plain unit B 1 is written into the serial number e of data voltage5=5, sub-pixel unit B2 are written into the serial number e of data voltage6=6.
Based on by above-mentioned sub-pixel unit it is corresponding write-in data voltage serial number calculate:
| (1+3+5)-(2+4+6) |=3 (2)
Therefore, the condition of the order coincidence formula (1) of above-mentioned sub-pixel unit write-in data voltage.

Time is obviously shortened compared to the prior art shown in Fig. 2, and the difference of electric leakage rise time reduces, also, same color
The electrical leakage quantity discrepancy delta Vmux of sub-pixel unit reduces, and then the gray scale voltage discrepancy delta Vp in pixel also reduces；And two
