It is electrically connected with display panel 11.Display panel 11 can have multiple pixel P, multiple pixel P electrical with driving circuit 12 respectively
Connection.Wherein, each pixel P can be respectively provided with a pixel electrode P1, a common electrode P2 and be folded in pixel electrode P1 and common electrode
Multiple liquid crystal molecule P3 between P2.When driving circuit 12 exports multiple data voltages and is sent to the pixel electricity of multiple pixel P
Pole P1, and export and have electrode voltage Vcom altogether and when being sent to the common electrode P2 of multiple pixel P, pixel electrode P1 and common-battery can be made
A voltage difference is formed between the P2 of pole, liquid crystal molecule P3 is made to can be rotated to certain angle, to realize the display of picture.
In the present embodiment, driving circuit 12 may include time schedule controller 121, one source driver 122 and a grid
Driver (is not painted).Gate drivers can be coupled by multi-strip scanning line and display panel 11, and source electrode driver 122 can lead to
It crosses multiple data lines and multiple pixel P of display panel 11 is coupled.Wherein, sequence controller 121 can transmit vertical synchronization starting

In figure 3, what V0~V7 was respectively represented is data voltage, and in order to realize pixel voltage (the pixel electricity of pixel P
Pressure is equal to voltage difference of the data voltage together between electrode voltage) polarity switching, avoid liquid crystal molecule from deteriorating, the present embodiment
The common-battery pole tension Vcom of each frame can carry out the switching of polarity of voltage, in other words, the source electrode driver of the present embodiment
In the common-battery pole tension Vcom of 122 outputs, the common-battery pole tension Vcom of adjacent two frame (nth frame and N+1 frames, N is positive integer)
Polarity on the contrary, and this switching action proceed by when being the blank time tb between nth frame and N+1 frames.
In addition, it is assumed that common-battery pole tension Vcom is in nth frame time TnInterior correct voltage value is one first
Voltage V1, and common-battery pole tension Vcom is in N+1 frame times Tn+1Interior correct voltage value is a second voltage V2, and wherein N is big
In the positive integer equal to 1, and first voltage V1 is opposite with the polarity of second voltage V2.Due to being total to for large-sized display panel 11
The area of electrode P2 is larger, causes its parasitic capacitance also larger, therefore, when source electrode driver 122 is when blank time tb starts

A time difference t1 of two voltage V2.Wherein, source electrode driver 122 is to make first voltage V1 start to change in blank time tb,
And in N+1 frame times Tn+1Voltage is inside set to be changed to second voltage V2 by first voltage V1.The present embodiment can be examined by an outside
Slowdown monitoring circuit 2 (please referring to Fig. 1) detects the voltage value of common-battery pole tension Vcom, and then obtains this voltage and change to second voltage V2's
Time difference t1.As shown in figure 4, this time difference t1 is equal to the time that N+1 frames start, electrode voltage Vcom reaches the second electricity together
Press the time interval of v2.
Then, step S02 is：Source electrode driver 122 is controlled by sequence controller 121 after N+1 frames start to postpone
The time difference t1 transmits multiple data voltages to multiple pixel P.Due to after delay-time difference t1, the common-battery of N+1 frames
The voltage value of pole P2 can just reach second voltage V2, therefore, source electrode driver 122 can be controlled by sequence controller 121 in N
After+1 frame starts and before time difference t1, data voltage is not transmitted to pixel P, but starts and postpones in N+1 frames
After time difference t1, sequence controller 121 just makes source electrode driver 122 transmit data voltage to pixel electrode P1, in this way, pixel
The pixel voltage of P is only the system correct voltage to be arranged, and display panel 11 is made not will produce color offset phenomenon.
On the implementation, the voltage value of the common-battery pole tension Vcom of pixel P can be first measured by outer detecting circuit 2 in N+1
Frame time Tn+1It is interior to be changed to the time difference t1 of second voltage V2 by first voltage V1, and then obtain time t2, wherein in N+1
Frame time (Tn+1) in, source electrode driver 122 transmits multiple data voltages to the time (t2) of multiple pixel P, is equal to N+1 frames
Time (Tn+1) subtract time difference (t1), i.e. t2=Tn+1-t1.Later, to sequence controller 121 into changing under line, Yi Jichong
Newly sequence controller 121 is encoded, the delay output that source electrode driver 122 can be completed after the completion of change is filled with each row
The electric time redefines, and in other words, modified sequence controller 121 is made to can control source electrode driver 122 in N+1 frames
Start and after delay-time difference t1 just the data voltage of transmission pieces of data line to each pixel P.Therefore, the liquid crystal of the present embodiment
The mode that common electrode voltage modulation drives can be applied to large size panel, can not only had by display device 1 and its driving method
The effect of source electrode driver power consumption is reduced, nor large size panel can be made to generate color offset phenomenon.
In conclusion in the liquid crystal display device and its driving method of the present invention, by the electricity for detecting common-battery pole tension
After pressure value changes the time difference to second voltage after N+1 frames start, then pass through the source of sequence controller control driving circuit
Driver postpones the multiple data voltages of the time difference transmission to multiple pixels after N+1 frames start.Whereby, by above-mentioned
Driving method, mode that common electrode voltage modulation drives can be applied to large size panel, not only can reach reduction by the present invention
The effect of source electrode driver power consumption, nor large size panel can be made to generate color offset phenomenon.
