Description
Technical field
The present invention relates to display technology field, more particularly, to liquid crystal display panel, display device and scanning side
Method.
Background technology
At present, when liquid crystal panel is used, the need for actual displayed effect, it is desirable to which panel has the positive and negative work(swept
Can, and designed for some current panels, the rgb pixel of starting and ending is arranged in order, it is desirable to which counter sweeping is accomplished by switching
For the scan pattern data that time schedule controller reads, during display data reversely to be sent into source electrode driver.
But setting the positive and negative scan pattern data swept needs to store in two memory cell, for time schedule controller selection,
Memory cell can take the space of excessive printed circuit board (PCB), while also add cost.
The first structural representation of colored filter, R, G, B in the liquid crystal display panel that Fig. 1 shows according to prior art
The filter unit of redgreenblue is represented respectively, the filter unit color all same on each row, the filter unit in every a line
It is alternately arranged by R, G, B, such aligning method is referred to as stripe-arrangement.
Second structural representation of colored filter, identical in the liquid crystal display panel that Fig. 2 shows according to prior art
The filter unit of color is diagonally arranged, and the filter unit in every a line is alternately arranged by R, G, B, and such aligning method claims
It is mosaic arrangement.
The third structural representation of colored filter, every four in the liquid crystal display panel that Fig. 3 shows according to prior art
Individual filter unit forms one " square ", then by so identical " square " Mi Pu for constituting, such aligning method is referred to as
Square arrangement.
Fig. 4 shows to sweep principle schematic according to the liquid crystal display panel of prior art is positive and negative, and for sake of clarity, Fig. 4 shows
Go out in a line filter unit of colored filter, two groups of filter units of capable center line both sides, every group of filter unit includes
The filter unit of redgreenblue, Fig. 4 also show the part in the thin film transistor (TFT) array being correspondingly arranged with colored filter
Circuit.As shown in figure 4, R, G, B represent the filter unit of redgreenblue respectively, one is correspondingly arranged on for each filter unit
Individual pixel electrode, for the sake of clarity, the pixel electrode not shown in figure.G1 represents a grid on thin film transistor (TFT) array
Polar curve, S1 to S6 represents the source electrode line on thin film transistor (TFT) array, in addition with being connected to the gate line and source electrode line and have
There is the thin film transistor (TFT) of drain electrode.The drain electrode of thin film transistor (TFT) connects the pixel electrode, enters by the pixel electrode
Row charging makes liquid crystal molecule change the optical filtering work of arrangement, the light transmittance of change liquid crystal, then the filter unit by redgreenblue
With the colors for making pixel presentation different.In the case of forward scan, gate driving circuit is by the gate lines G 1 successively company of gating
The pixel electrode of source electrode line S1 to S6 is connected to, so that source electrode drive circuit passes sequentially through source electrode line S1 to S6 to corresponding pixel electricity
Charge pole.The charge data of source electrode line S1 to S6 is followed successively by L1, L2, L3, L4, L5 and L6, then have following corresponding relation：R correspondences
In L1, G corresponds to L2, and B corresponds to L3, and R corresponds to L4, and G corresponds to L5, and B corresponds to L6.And in the case of reverse scan,
Charging order is opposite：R corresponds to L6, and G corresponds to L5, and B corresponds to L4, and R corresponds to L3, and G corresponds to L2, and B corresponds to L1, so
Charging mistake is will result in, shows pixel abnormal.So time schedule controller needs to call different scan pattern data so that
Anti- charge data of sweeping is adjusted, it is counter sweep charge data adjustment after, R corresponds to L4, and G corresponds to L5, and B corresponds to L6, and R corresponds to
L1, G correspond to L2, and B corresponds to L3, charges correct, can show and correct counter sweep image.But the positive and negative scan pattern number swept
According to need to be respectively stored into two EEPROMs for time schedule controller select.However, setting two
EEPROM also increases cost while the space of printed circuit board (PCB) is influenceed.
