Except respective first frame, the driving signal of any sub-pixel is by being somebody's turn to do in other frames of first stage and second stage
Sub-pixel is determined in the original signal of this frame.
Wherein, that is to say, that in the first phase driving signal polarity of the same data line in any consecutive frame on the contrary,
Same data line is in the driving signal polarity in any consecutive frame on the contrary, every in each stage to be formed in second stage
The polarity of a sub-pixel inverts.
In the first stage and in second stage, the variation pattern of the signal polarity of same data line is different, for example, if the
In one stage, the variation of signal polarity of the same data line since first frame are as follows: negative and positive negative and positive negative and positive, and in second stage
In, the variation of signal polarity of the same data line since first frame are as follows: positive and negative positive and negative.
It should be noted that the driving signal of each sub-pixel is the signal for actually making the sub-pixel for emitting light；Each sub-pixel
Original signal is every height as the signal that should theoretically input, the original signal of each sub-pixel can deposit in advance when polarity inverts
Storage is in the storage unit of liquid crystal display panel.
Since the sub-pixel of second stage last frame is identical as the polarity of the sub-pixel of first stage first frame, therefore quite
Polarity reversion, the i.e. sub- picture of the sub-pixel of the frame and remaining frame of second stage do not occur in the sub-pixel of second stage last frame
The changing rule of element is different.
In the driving method of the liquid crystal display panel of the present embodiment, in the first frame of second stage, at least partly sub-pixel
Driving signal pass through the sub-pixel original signal of last frame and in the original of second stage first frame in the first stage
Signal determines, is equivalent to being modified for the original signal of the corresponding sub-pixel to second stage last frame, so as to improve the
The first frame display effect of two-stage, avoids the frame from occurring showing the defects of bright, so that the liquid crystal display panel is shown
Display brightness is uniform, and to improve display picture quality, (wherein the waveform diagram of the figure is by light-sensitive element Photo as shown in Figure 3
Sensor is measured).
It should be noted that first stage and second stage can be regarded as two week of arbitrary continuation in the driving method
Phase, i.e. first stage can indicate n-th of period, and second stage can indicate (n+1)th period；As a result, to the n-th+2 periods and
Speech, the second stage (the (n+1)th period) of script are equivalent to the first stage, therefore the driving signal of the first frame in the n-th+2 period
It can handle in the above manner.
Embodiment 2:
As shown in Figures 2 to 6, the present embodiment provides a kind of driving methods of liquid crystal display panel, wherein the liquid crystal display
Panel includes multiple data lines, and every data line connects multiple sub-pixels.
This method provides driving signal to each sub-pixel by data line in every frame, connects same data line in every frame
The driving signal polarity of sub-pixel is identical, and method includes:
First stage comprising the continuous frame of even number, the driving signal pole in any sub-pixel two consecutive frames of meaning in office
Property is opposite；
Second stage comprising the continuous frame of even number, the driving signal pole in any sub-pixel two consecutive frames of meaning in office
Property is opposite；
Wherein, any sub-pixel in the first stage in last frame and second stage first frame driving signal polarity phase
Together；In the first frame of second stage, at least partly the driving signal of sub-pixel by the sub-pixel in the first stage last
The original signal of frame and second stage first frame original signal determine；
Except respective first frame, the driving signal of any sub-pixel is by being somebody's turn to do in other frames of first stage and second stage
Sub-pixel is determined in the original signal of this frame.
Wherein, wherein that is driving signal polarity of the same data line in any consecutive frame in the first phase
On the contrary, driving signal polarity of the same data line in any consecutive frame is on the contrary, to form each stage in second stage
In each sub-pixel polarity reversion.
In the first stage and in second stage, the variation pattern of the signal polarity of same data line is different, for example, if the
In one stage, the variation of signal polarity of the same data line since first frame are as follows: negative and positive negative and positive negative and positive, and in second stage
In, the variation of signal polarity of the same data line since first frame are as follows: positive and negative positive and negative.
It should be noted that the driving signal of each sub-pixel is the signal for actually making the sub-pixel for emitting light；Each sub-pixel
Original signal is every height as the signal that should theoretically input, the original signal of each sub-pixel can deposit in advance when polarity inverts
Storage is in the storage unit of liquid crystal display panel.
Since the sub-pixel of second stage last frame is identical as the polarity of the sub-pixel of first stage first frame, therefore quite
Polarity reversion, the i.e. sub- picture of the sub-pixel of the frame and remaining frame of second stage do not occur in the sub-pixel of second stage last frame
The changing rule of element is different.
In the driving method of the liquid crystal display panel of the present embodiment, in the first frame of second stage, at least partly sub-pixel
Driving signal pass through the sub-pixel original signal of last frame and in the original of second stage first frame in the first stage
Signal determines, is equivalent to being modified for the original signal of the corresponding sub-pixel to second stage last frame, so as to improve the
The first frame display effect of two-stage, avoids the frame from occurring showing the defects of bright, so that the liquid crystal display panel is shown
Display brightness is uniform, to improve display picture quality, as shown in Figure 3.
It should be noted that first stage and second stage can be regarded as two week of arbitrary continuation in the driving method
Phase, i.e. first stage can indicate n-th of period, and second stage can indicate (n+1)th period；As a result, to the n-th+2 periods and
Speech, the second stage (the (n+1)th period) of script are equivalent to the first stage, therefore the driving signal of the first frame in the n-th+2 period
It can handle in the above manner.
Preferably, the number for the frame that the first stage includes is equal with the number for the frame that second stage includes.
Wherein, since the display duration of each frame is certain (such as 1 second 60 frames of display, a length of 1/ when the display of every frame
60s), then the display duration of first stage and second stage is equal, for example, the display duration of first stage and second stage is
28s, if the quantity for the frame that 1 second 60 frame of display, first stage and second stage include is 1680, to realize that 28S POL is anti-
Turn technology.
Can be spaced in this way first frame from regular time to second stage sub-pixel provide by former frame sub-pixel
Original signal and the frame original signal determination driving signal, and to the sub-pixel of remaining frame provide by the frame original letter
Number determining driving signal improves efficiency so that the driving method simplifies.
Specifically, the voltage of the driving signal of any sub-pixel is according to the sub-pixel first in the first frame of second stage
The original signal of the original signal of stage last frame and the first frame in second stage is obtained according to scheduled corresponding relationship.
That is, as shown in figure 4, the driving pre-set about same sub-pixel in the first frame of second stage is believed
Number voltage, in the first stage the original signal of last frame, second stage first frame original signal corresponding relationship
Table, any group of every kind of original signal of the first frame of every kind of original signal and second stage for first stage last frame
Close, it is settable go out corresponding second stage first frame driving signal voltage.
For example, the voltage of the driving signal of any sub-pixel is according to the sub-pixel in the first rank in the first frame of second stage
The section corresponding gray scale voltage of original signal of last frame and the corresponding grayscale of original signal of the first frame in second stage
The corresponding relationship of voltage obtains (certainly can also according to grayscale value of original signal etc. other data obtain).
Further, if it is equal with the original signal of certain sub-pixel in the first frame of second stage in first stage last frame
In predetermined range, then the sub-pixel the driving signal of the first frame of second stage voltage according to the sub-pixel first
The original signal of the original signal of stage last frame and the first frame in second stage is obtained according to scheduled corresponding relationship.
For example, if the original signal of the first frame sub-pixel of second stage in scheduled grey-scale range, the sub- picture
Element driving signal voltage according to the sub-pixel in the first stage the corresponding gray scale voltage of original signal of last frame and
The corresponding relationship of the corresponding gray scale voltage of the original signal of the first frame of second stage obtains.
Wherein, that is to say, that the driving signal of the first frame sub-pixel of not every second stage is all by the sub-pixel
The original signal of the first frame of the original signal and second stage of last frame obtains in the first stage, but works as the first stage
The original signal of last frame and the first frame sub-pixel of second stage is in scheduled grey-scale range, the drive of the sub-pixel
Dynamic signal is just determined by above method.
For example, the original signal of first stage last frame and the first frame sub-pixel of second stage is 100 to 154
In grey-scale range (especially in 127 grayscale), the voltage of the driving signal of the sub-pixel is just according to the sub-pixel in the first rank
The corresponding grayscale electricity of the original signal of the first frame of the corresponding gray scale voltage of original signal and second stage of section last frame
The corresponding relationship of pressure obtains.
Because the difference of the brightness of the first frame sub-pixel of the second stage in the present invention is only in certain grey-scale ranges
(such as in 100 to 154 grey-scale ranges) are obvious；And its luminance difference is not obvious in other grey-scale ranges, even if not to the son
The driving signal of pixel, which is modified, will not cause luminance defects.Therefore it can be shown guaranteeing liquid crystal display panel with upper type
Under the premise of performance, simplify the driving method, to improve efficiency.
Preferably, the array of sub-pixels arrangement of liquid crystal display panel, every data line connects a column sub-pixel, in column direction
Upper liquid crystal display panel is divided into multiple regions；At least partly voltage root of the driving signal of sub-pixel in the first frame of second stage
According to the sub-pixel in the first stage the original signal of last frame and second stage first frame original signal according to pre-
Fixed corresponding relationship obtains, and scheduled corresponding relationship is different in the different areas.
Wherein, the sub-pixel remote with range data line input terminal due to the pressure drop of the close sub-pixel of range data line input terminal
Pressure drop it is different, the driving signal of sub-pixel different in the first frame of second stage needs modified degree different in this way,
Therefore in the first frame of second stage the driving signal of different sub-pixel and the sub-pixel last frame in the first stage original
