It should be noted that shown in as shown in Figure 3a and corresponding 3b driver' s timing, in order to realize adjacent R, G, B picture
Element is the interspersed driving arrangement mode of high-low voltage, and Vg1 is that a line even column sub-pixel is swept altogether with adjacent a line odd column sub-pixel
Driving signal is retouched, Vg2 is that same Vg1 is that a line odd column sub-pixel and adjacent a line even column sub-pixel are total to scanning drive signal,
Such as Fig. 3 b driver' s timing, it is set as opposite polarity with the polarity of two adjacent subpixels of same column due to that will go together, to described same
Capable and same column sub-pixel is driven using the driving method of dot inversion, and the turn-on time for controlling Vg1 believes data-driven
Number it is smaller for data drive signal compared to the turn-on time with Vg2, to make the corresponding sub- picture of Vg1 scanning drive signal
Plain charging ability is deteriorated, and sub-pixel charging ability corresponding with Vg2 scanning drive signal becomes strong, to reach high voltage sub-pixel
The purpose of charging and low-voltage sub-pixel time charging, and then reach the effect of color bias improvement.
Step S30, in the first row pixel unit in the drive cycle odd column sub-pixel and adjacent a line picture
Even column sub-pixel in plain unit is driven using the described second default scanning drive signal.
It is understood that controlling Vg1 scanning switch timing relative to the charging signals of data drive signal compared to Vg2
Scanning switch timing it is shorter relative to the turn-on time of data drive signal, the corresponding sub- picture of Vg1 turntable driving route can be made
Plain charging ability is deteriorated, and sub-pixel charging ability corresponding with Vg2 sweep circuit becomes strong, to reach the charging of high voltage sub-pixel
The difference to charge with low-voltage sub-pixel, and then reach the effect of color bias improvement.
Step S40, the preset data driving signal driven to each column sub-pixel in same column pixel unit, which uses, wears
The mode of insert row column is configured.
In the present embodiment, data drive signal is cooperated by scanning drive signal, the data drive signal is used
The design of left and right sub-pixel driver circuit, the same same data-driven route of polarity driven reduce polar frequent driving, reach drop

As shown in Figure 3a, Vd1 data drive signal drives G and R sub-pixel anode temper picture element VGd_1, VRd_2, VGd_
3, the corresponding scanning drive signal of VRd_4, VGd_5, VRd_6 is Vg2, and Vd2 data drive signal drives G and B sub-pixel cathode
Temper picture element VBd_1, VGd_2, VBd_3, VGd_4, VBd_5, VGd_6 corresponding scanning drive signal is Vg1, wherein Vg1
Scanning switch timing △ t1 for data drive signal turn-on time, compared to Vg2 scanning switch timing △ t2 in data
Driving signal is smaller, i.e. △ t1 < △ t2.
In the step S40, comprising:
It is default using first to the first polarity sub-pixel in the odd-numbered line of each column sub-pixel in same row pixel unit
Data drive signal is driven, to the second polarity sub-pixel in the even number line of each column sub-pixel in same row pixel unit
It is driven using the second preset data driving signal.
It is understood that as shown in Figure 3b, Vd1 data drive signal is sequentially that the driving of G positive polarity and R positive polarity are driven
Dynamic, Vd1=VG1, VR1, VG2, VR2, VG3, VR3 ..., cooperation scanning drive signal distinguish Vg2_1, Vg2_2, Vg2_3, Vg2_
4, Vg2_5, Vg2_6, scanning switch timing are △ t2, are sequentially the driving of B negative polarity and G negative polarity with time Vd2 driving signal

State the average value for the history driving signal that third preset data driving signal is the adjacent subpixels.
It should be noted that the driving signal that the history driving signal is the adjacent two sub-pixels of history same column is to change
The driving signal of the two sub-pixels adjacent into preceding same column, to the equivalent driving voltage VGd_1 of the two neighboring sub-pixel of same column
It is driven respectively with positive polarity driving voltage Vgd=VG1 and negative polarity driving voltage Vgd=VG1' with the equivalent voltage of VGd_2, just
Polarity driven voltage VG1 and negative polarity driving voltage VG1' is then chosen as the average signal of original pixel signal Gd1 Yu Gd2 signal,
With for 8bit driving signal for 0~255 signal, that is, the corresponding positive polarity driving voltage of G1=(Gd1+Gd2)/2, G1 signal
VG1 and negative polarity driving voltage VG1'.VGd_3 and VGd_4 equivalent voltage with positive polarity driving voltage Vgd=VG2 and are born respectively
Polarity driven voltage Vgd=VG2' driving, then be chosen as the average signal of original image frame picture element signal Gd3 and Gd4 signal, with 8bit
For driving signal be 0~255 signal, that is, the corresponding positive polarity driving voltage VG2 of G2=(Gd3+Gd4)/2, G2 signal and

In the present embodiment with write driving signal reversion, scanning drive signal switch for data drive signal △ t1,
△ t2 can also cooperate switching, that is, the scanning drive signal switching sequence of Vg1 is △ t2 for data drive signal, and Vg2's sweeps
Retouching driving signal switching sequence is △ t1 for data drive signal, so that different timing difference high-low voltage signals can be realized
Son portrait element, and naked eyes will not obviously see the difference of high voltage sub-pixel Yu low-voltage sub-pixel, be not in solution therefore
The problem of analysis degree declines.
In one embodiment, before the step S10, the method also includes:
