Technological means solving technical problem, and reach relevant art effect realize that process can fully understand and implement according to this.This Shen
Each feature that please be in embodiment and embodiment, can be combined with each other under the premise of not colliding, the technical scheme for being formed
Within protection scope of the present invention.
First embodiment：
Fig. 1 is the block diagram representation of multiple GOA units in GOA drive circuits in prior art.As illustrated, at each
In GOA unit, it is provided with signal input module, signal (line scan signals) output module and level and passes signal input output
End.Two adjacent GOA units can pass through given level and pass signal, realize sweeping the forward direction of each row pixel cell of display floater
Retouch and reverse scan, specifically as shown in Figure 2 a and 2 b.
Fig. 2 a are the forward scan schematic diagram that interlacing scan drives in prior art, and Fig. 2 b are the reverse of interlacing scan driving
Scanning schematic diagram.GOA drive circuits are separately positioned on the left and right sides of viewing area, and are arranged on the part GOA drivings in left side
Circuit is used to drive each odd-line pixels unit, is arranged on the part GOA drive circuits on right side and is used to drive each even rows
Unit.
During actual scanning, as shown in Figure 2 a, during forward scan, by first GOA unit on the left of being arranged on to the first row
Pixel cell is scanned driving, and next sequential is entered by first GOA unit for being arranged on right side to the second row pixel cell
Row turntable driving, next sequential is scanned drive by second GOA unit for being arranged on left side to the third line pixel cell
Dynamic, next sequential is scanned driving by second GOA unit for being arranged on right side to fourth line pixel cell, is followed with this
Ring goes down.During reverse scan, scanning process, referring to Fig. 2 b, is repeated no more similar to the process of above-mentioned forward scan.
Further, it is readily appreciated that, when with it is above-mentioned it is positive and negative sweep method display floater be driven when, if to realize picture
The dot inversion of plain unit, then need shifting to even number line from odd-numbered line per data line, and from even number line shift to odd-numbered line when
Change the polarity of the data-signal of its transmission, this consumption to data-driven IC is very big.
In embodiments of the present invention, first driving, then antithesis several rows are scanned to the odd-line pixels unit of display floater
Pixel cell is scanned driving.Or first driving is scanned to the even rows unit of display floater, then to odd-numbered line
Pixel cell is scanned driving.It is specifically described below.
Fig. 3 is the schematic flow sheet of the driving method of the display floater according to first embodiment of the invention, as illustrated, should
Driving method includes：
Step S310, progressive scan driving is carried out to even odd several rows pixel cell, to each odd number column data line and each even number
Column data line applies opposite polarity data-signal.
After step S320, the turntable driving for completing to even odd several rows pixel cell, the data letter of each data wire will be put on
Number polarity inversion.
Step S330, from the beginning of the idol adjacent with the even odd several rows pixel cell/odd-line pixels unit, antithesis/odd number
Row pixel cell carries out progressive scan driving, and opposite polarity data are applied with each even number column data line to each odd number column data line
Signal.
In step S310, the first row pixel cell is scanned first with first GOA unit for being arranged on left side
Drive, next sequential, driving is scanned to the third line pixel cell using second GOA unit for being arranged on left side, under
One sequential, driving is scanned using the 3rd GOA unit for being arranged on left side to fifth line pixel cell, the like,
Until completing the turntable driving to K+2 row pixel cells.
To realize the dot inversion of pixel cell, the polarity for needing data-signal in each data wire is engaged, and specifically, is showing
During one frame picture, when driving is scanned to every row odd-line pixels unit, to odd number column data line positive polarity or negative is applied
The data-signal of polarity, to even number column data line the data-signal of negative polarity or positive polarity is applied.
In step s 320, remaining even rows unit is scanned before driving in same frame picture, to
Odd number column data line applies the data-signal of negative polarity or positive polarity, and to even number column data line the number of positive polarity or negative polarity is applied
It is believed that number.
In step S330, from the even number line adjacent with last column odd-line pixels unit scanned in step S310
Pixel cell starts turntable driving.Specifically, first with last GOA unit on the right side of being arranged on to K+3 row pixels
Unit is scanned driving, next sequential, using the penultimate GOA unit on the right side of being arranged on to K+1 row pixel lists
Unit is scanned driving, next sequential, using the third last GOA unit on the right side of being arranged on to K-1 row pixel cells
Driving is scanned, the like, until completing the turntable driving to the second row pixel cell.
Likewise, the dot inversion to realize pixel cell, the polarity of data-signal is engaged in each data wire of need, specifically
, when a frame picture is shown, when driving is scanned to every row even rows unit, apply negative to odd number column data line
The data-signal of polarity or positive polarity, to even number column data line the data-signal of positive polarity or negative polarity is applied.
It is further to note that as shown in Figure 2 a and 2 b, with K+2 rows (odd-numbered line for finally scanning) pixel cell
Adjacent even rows unit has two rows, K+1 rows pixel cell and K+3 row pixel cells, during switching, from positioned at odd number
The even rows unit of row pixel cell scanning direction forward location starts scanning, i.e., positioned at the even rows of the last row
Unit.
In the display for terminating present frame picture, before carrying out the display of next frame picture, the number of each data wire will be put on
It is believed that number polarity inversion.It is easily understood that due in the present embodiment to odd-line pixels unit and even rows
Unit difference turntable driving, so if by the polarity inversion of the data-signal for putting on each data wire, then aobvious in switching
When showing frame, polarity of the pixel cell at co-located point in two adjacent frame pictures is identical.
Further, in the display for terminating present frame picture, before carrying out the display of next frame picture, it is also possible to which maintenance is applied
The polarity for being added on the data-signal of each data wire is constant, now, when switching shows frame, the pixel list at co-located point
Polarity of the unit in two adjacent frame pictures is contrary.
It is last it should be noted that in the present embodiment, odd-line pixels unit is carried out progressively scan the direction of driving with
Antithesis several rows pixel cell carries out progressively scanning the direction of driving and keeps contrary.
As can be seen that the scanning drive method in the present embodiment, in a frame picture, it is only necessary to which data on data wire are believed
Number positive-negative polarity switching once can be achieved with the dot inversion of viewing area.In continuous image frame, it is only necessary to maintain data
The constant dot inversion that can be realized as between multiframe picture of the polarity of data-signal on line.Compared to realizing showing in prior art
Show the upset of point completely in region, the power consumption of data-driven IC will be significantly reduced.
