Description
Technical field
The present invention relates to technical field of liquid crystal display, and in particular to a kind of array substrate, liquid crystal display panel and its driving
Method.
Background technique
Liquid crystal display device (liquid crystal display, LCD) has good, small in size, light-weight, the low drive of image quality
Dynamic voltage, low-power consumption, radiationless and relatively low manufacturing cost advantage, occupy an leading position in flat display field.
As social economy and scientific and technical are constantly progressive, display user is for the property shared data and confidentiality data
With different visual demands, the display of single visual angle mode is no longer satisfied the demand of user.Liquid crystal display is most
Possess well from the ability converted between wide and narrow viewing angle modes, when user needs shared information, opens wide viewing angle mode；When
When user wants protection display information, narrow viewing angle mode is used.
The wide viewing angle and narrow viewing angle of liquid crystal display are switched currently, being mainly the following mode and realizing.The first makes
Function is blocked come what is realized with shutter, and this mode needs additionally to prepare blinds Protective film, causes greatly to user
Inconvenience, and a blinds Protective film can only realize a kind of visual angle, and after attaching upper blinds Protective film, visual angle is just secured.
In recent years, industry also starts to propose to apply using the viewing angle control electrode of colored optical filtering substrates side to liquid crystal molecule
One vertical electric field, to realize width view angle switch.Fig. 1 is a kind of partial cross section of the existing liquid crystal display panel under wide viewing angle
Schematic diagram.Fig. 2 is schematic partial cross-sectional view of the liquid crystal display panel under narrow viewing angle in Fig. 1.Fig. 1 and Fig. 2 are please referred to, the liquid crystal
Display device includes first substrate 11, the second substrate 12 and the liquid crystal layer 13 between first substrate 11 and the second substrate 12,
First substrate 11 is equipped with viewing angle control electrode 111.As shown in Figure 1, the visual angle control in wide viewing angle display, on first substrate 11
Electrode 111 processed does not give voltage, and liquid crystal display device realizes that wide viewing angle is shown.As shown in Fig. 2, when needing narrow viewing angle to show, the
Viewing angle control electrode 111 on one substrate 11 gives voltage, and the liquid crystal molecule in liquid crystal layer 13 is while rotating horizontally because hanging down
Histogram to electric field (as shown in arrow E in figure) and tilt, liquid crystal display device is final to realize because light leakage and contrast reduce
Narrow viewing angle.
But this mode can only realize the width view angle switch on left and right directions, cannot realize simultaneously left and right directions and/
Or the width view angle switch in up and down direction.
In narrow viewing angle display, added voltage is generally alternating voltage on viewing angle control electrode.Liquid crystal display device exists
It when showing a frame picture, is progressively scanned along direction from top to bottom, since viewing angle control electrode is entire plane electricity
Pole, when the first horizontal scanning line G1 is opened, viewing angle control electrode is already endowed with alternating voltage, when following G2-Gn is opened,
The voltage of scan line is changed to VGL by VGH, since the capacitive coupling between scan line and viewing angle control electrode influences, per instantly
When one horizontal scanning line is opened, the signal on viewing angle control electrode is coupled once, cause the pixel of different location in panel by
Coupling influence to signal is inconsistent, causes to cause film flicker, apparent bright dark fringe occurs in waveform voltage trip point,
The problem of band-like display of position region property of the liquid crystal display device close to lower end uneven (band mura).
In order to solve this problem, the prior art passes through the drive waveforms to the alternating voltage being applied on viewing angle control electrode
It is optimized with driving voltage to reduce the uneven influence of caused display, but cannot be completely eliminated；Or by by liquid
The frame frequency of crystal device is increased to 120Hz, and to mitigate the flashing of picture, but the time that every scan line in this way is opened subtracts
Half, the charging time of pixel can be reduced, the charging effect of pixel is impacted.

In two adjacent groups data-signal, the graphics control signals positioned at first group of data-signal middle position and the number positioned at second group
It is believed that the graphics control signals in number middle position carry out first time exchange, when two graphics control signals are inputted by lead (204)
When to data line (22), passes through lead (204) and carry out second and exchange；The corresponding bipolarity of two graphics control signals controls signal
First time exchange is carried out by lead (204) simultaneously, and two graphics control signals and the polarity control signal after exchanging are transmitted to pair
On the data line (22) answered.
9. a kind of driving method of liquid crystal display panel (100), the liquid crystal display panel (100) include array substrate (20),
It is characterized in that, which includes：
In two adjacent groups data line, the lead that is connected of data line (22) in first group of data line middle position will be located at
(204) it is exchanged with the lead (204) that is connected of the data line (22) positioned at second group of data line middle position；
Data-signal is converted into Format Series Lines by the coding module (52) of sequence controller (50), and with every three adjacent data
Signal is one group, which includes graphics control signals and polarity control signal, by two adjacent groups data-signal, by position
Graphics control signals among first group of data-signal and the graphics control signals among second group of data-signal carry out
It exchanges, the output position of the polarity control signal in two groups of data-signals is constant, matches with the graphics control signals after exchange defeated
Enter to the data line (22) connected.
10. the driving method of liquid crystal display panel (100) as claimed in claim 9, which is characterized in that
When the liquid crystal display panel (100) is driven using column inversion, in two adjacent groups data line, first group of data line interposition
The data line (22) set and the received polarity control signal of the data line (22) positioned at second group of data line middle position are exchanged, and are made
Three data line (22) the received polarity control signals obtained in every group of data line are identical, realize the driving of three column inversions；
When the liquid crystal display panel (100) is driven using dot inversion, in two adjacent groups data line, it is located in first group of data line
Between position data line (22) and the received polarity control signal of data line (22) positioned at second group of data line middle position hand over
Fork exchanges, so that three data line (22) received polarity control signals in every group of data line are identical, realizes every a line with three
A sub-pixel is the reversion of unit positive-negative polarity；
When the liquid crystal display panel (100) is driven using two dot inversion of column, in two adjacent groups data line, it is located at first group of data
The data line (22) in line middle position and the received polarity control letter of data line (22) positioned at second group of data line middle position
Number cross exchanged is realized each so that the three received sub-pixel polar signals of data line (22) in every group of data line are identical
Column are inverted by unit positive-negative polarity of two sub-pixels, and every a line is inverted by unit positive-negative polarity of three sub-pixels.
