As shown in figure 5, Fig. 5 is that the invention shows the flow diagram of one embodiment of panel driving method, the display panels
Driving method includes:
S10, output data control signal and scan control signal.
In the present embodiment, data controlling signal and scanning drive signal are exported by sequence controller 10, are respectively used to drive
There are many formats of data drive circuit and scan drive circuit work, data drive signal and scanning drive signal, such as TTL
(Transistor Transistor Logic, transistor-transistor logic level) signal, mini-LVDS (mini Low
Voltage Differential Signaling, miniature low voltage difference) signal and RSDS (Reduced Swing
Differential Signaling, low swing differential) formats, every kind of signal such as signal correspond to respective signaling interface skill again
Art, i.e. interfacing not only define the characteristics of transmission signal, but also define the format of transmission signal.
S20, scan control signal is converted to line scan signals, and exported to the scan line of display panel 200.
Row scan control signal exports line scan signals after the conversion of scan drive circuit 20, and scanning signal is aobvious for controlling
The gray scale voltage signal for showing that each row sub-pixel of panel 200 is opened line by line, and data drive circuit 30 being cooperated to export realizes display
The image of panel 200 shows that it is shift pulse signal, a pulse signal week that the scan line of display panel 200, which receives,
Phase indicate a line scan signals, fall down from above or from top to bottom line by line open display panel each row sub-pixel, per a period of time
Between point only have a line sub-pixel to open, other row sub-pixels remain off.
S30, data controlling signal is converted to gray scale voltage signal and is exported to 200 data line of display panel；
Polarity of the gray scale voltage signal in the adjacent two frames picture in front and back on data line is on the contrary, each in each frame picture
Row sub-pixel is inverted every m column polarity, and it is opposite to correspond to polarity for the gray scale voltage signal of two adjacent data lines in m column data line
The first signal and the second signal, the first signal be greater than positive polarity benchmark gray scale voltage signal, second signal be less than negative polarity
Gray scale reference voltage signal, m be more than or equal to 2, and m be even number.
In the present embodiment, data controlling signal exports gray scale voltage signal after the conversion of data drive circuit 30, and exports
The first signal be greater than greater than positive polarity gray scale reference voltage signal, second signal be less than negative polarity gray scale reference voltage believe
Number, to realize wide visual angle function, improve the display effect of display panel.
As shown in Figures 2 and 3, the gray scale voltage signal polarity on the first data line D1 to the 13rd data line D13 is upper
One frame picture and next frame realize polarity column inversion, and same data line polarity is on the contrary, and for each son in consecutive frame picture
For pixel, previous frame picture and next frame picture then realize dot inversion.
As shown in Fig. 2, the gray scale voltage signal being input in display panel carries out polarity reversion, i.e. kth m to arrange every m
Gray scale voltage signal on data line is identical as the gray scale voltage signal polarity on kth m+1 data line, and k is more than or equal to 1, m
More than or equal to 2, and m is even number, while the gray scale voltage letter on the gray scale voltage signal to m data line on the first data line D1
It number is successively alternately the first signal and the second signal, and the ash on the gray scale voltage signal to 2m data line on m+1 data line
Rank voltage signal is then successively alternate second signal and the first signal, the gray scale voltage signal on 2m+1 data line to 3m
Gray scale voltage signal on data line then with the gray scale voltage on the gray scale voltage signal to m data line on the first data line D1
Signal is identical, and so on.
By taking m is equal to 6 as an example, in Fig. 2, polarity reversions are carried out every 6 column, the negative and positive negative and positive that is positive of the polarity on data line is negative

Positive and negative positive negative and positive, i.e. gray scale voltage signal on the 6th data line D6 and the gray scale voltage signal polarity phase on the 7th data line D7
It together and is positive polarity, the gray scale voltage signal on gray scale voltage signal and the 13rd data line D13 on the 12nd data line D12
Polarity is identical and is negative polarity, while the gray scale voltage signal on the gray scale voltage signal to the 6th data line on the first data line
The ash on gray scale voltage signal to the 12nd data line for successively alternate second signal and the first signal, on the 7th data line
Rank voltage signal is successively alternate the first signal and the second signal.
As shown in figure 4, for the first row sub-pixel in first frame picture, gray scale voltage signal of the first row to the 6th column
Because coupling causes public electrode voltages to deflect to positive polarity, and in the gray scale voltage signal of the 7th column to the 12nd column because of coupling
With causing public electrode voltages to deflect to negative polarity, the public electrode voltages of two deflections are cancelled out each other for cooperation, practical to public
The variable quantity of electrode voltage is zero, and in next frame picture, the voltage change of the public electrode voltages of the row sub-pixel then phase
Instead, but for the row, total public electrode voltages variable quantity is zero, the problem of so as to improve film flicker.
