Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on

Embodiment, belongs to the scope of protection of the invention.
The data that liquid crystal display panel is input into generally by the public voltage signal that public electrode is input into pixel electrode
Liquid crystal molecule is rotated in the electric field driven liquid crystal layer that signal is formed, and to change the transmission state of liquid crystal layer, realizes that image shows.It is existing
In some liquid crystal display panels, public voltage signal is changeless, and the corresponding public voltage signal of each pixel cell
It is identical.So, the electric-field intensity between the corresponding public electrode of each pixel cell and pixel electrode directly depends on data letter
Number size.
If public voltage signal is 2V, data-signal maximum amplitude is 12V, and minimum amplitude is -8V.So, common electrical
Pole is 10V with the maximum of the voltage difference of pixel electrode, and minimum value is -10V.When setting voltage difference is for 10V or 10V, pixel list
Unit drives liquid crystal molecule to cause that the light transmittance of pixel cell is maximum, and when voltage difference is 0, pixel cell drives liquid crystal molecule to cause picture
Plain unit it is light tight.
It can be seen that, in the prior art, data-signal need switched between 12V in -8V, the true amplitude of data-signal with
Voltage difference between negative amplitude is 20V, and the voltage difference of the positive and negative amplitude of data-signal is larger, causes data-signal to carry out voltage anti-
Power consumption when turning is larger.
Inventor's research finds, when driving pixel cell to be shown, changes existing public voltage signal for direct current is permanent
The type of drive of pressure, is that each pixel cell is provided separately public voltage signal so that the corresponding common electrical of each pixel cell
Pressure signal is switched over from the first current potential to the second current potential, can reduce the voltage difference of the positive and negative amplitude of data-signal, is entered
And the power consumption of voltage data signal reversion.
In technical solution of the present invention, the corresponding electrode block of the first pixel cell is input into the first public voltage signal, the second picture
The second common electric voltage of the plain corresponding electrode block input of unit.First public voltage signal and the second public voltage signal are square wave friendship
Stream signal.And first public voltage signal and the second public voltage signal opposite in phase, i.e., when the first public voltage signal is high
During current potential, the second public voltage signal is low potential.When the first public voltage signal is low potential, the second public voltage signal
It is high potential.
For example, high potential as 5V can be set, low potential is -5V.When the voltage difference for needing public electrode and pixel electrode
10V the most, when minimum value is -10V, using technical solution of the present invention, public voltage signal corresponding for any pixel cell
And data-signal, can set the first public voltage signal and the second public voltage signal with the phase phase of data-signal
Instead, that is to say, that when the first public voltage signal be on the occasion of when, data-signal is negative value, when the first public voltage signal is negative
During value, data-signal be on the occasion of, equally, when the second public voltage signal be on the occasion of when, data-signal is negative value, when second public
Voltage signal be negative value when, data-signal be on the occasion of.
So, when the public voltage signal of the corresponding input of pixel cell is+5V, data-signal is -5V, public electrode
It is 10V with the voltage difference of pixel point electrode, when the public voltage signal of pixel cell input is -5V, data-signal is 5V, public
Common electrode is -10V with the voltage difference of pixel point electrode.Now, the voltage difference of the positive and negative amplitude of data-signal is 10V, is dropped significantly
The low voltage difference of the positive and negative amplitude of data-signal, and then greatly reduce the power consumption of voltage data signal reversion.
