Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The data of public voltage signal and pixel electrode input that liquid crystal display panel is inputted generally by public electrode
Liquid crystal molecule rotation in the electric field driven liquid crystal layer that signal is formed realizes that image is shown to change the transmission state of liquid crystal layer.It is existing
In some liquid crystal display panels, public voltage signal is fixed and invariable, and the corresponding public voltage signal of each pixel unit
It is identical.In this way, the electric field strength between the corresponding public electrode of each pixel unit 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.In this way, common electrical
The maximum value of the voltage difference of pole and pixel electrode is 10V, and minimum value is -10V.When setting voltage difference as 10V or 10V, pixel list
Member driving liquid crystal molecule makes the light transmittance of pixel unit maximum, and when voltage difference is 0, pixel unit driving liquid crystal molecule makes picture
Plain unit it is opaque.
As it can be seen that in the prior art, data-signal needs are switched in -8V between 12V, 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.
For inventor the study found that when driving pixel unit to show, changing existing public voltage signal is that direct current is permanent
Public voltage signal is provided separately for each pixel unit, so that the corresponding common electrical of each pixel unit in the driving method of pressure
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, into
And the power consumption of voltage data signal reversion.
In technical solution of the present invention, the corresponding electrode block of the first pixel unit inputs the first public voltage signal, the second picture
The second common voltage of the plain corresponding electrode block input of unit.First public voltage signal and the second public voltage signal are that square wave is handed over
Flow 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
When current potential, the second public voltage signal is low potential.When the first public voltage signal is low potential, the second public voltage signal
For high potential.
For example, high potential can be set as 5V, 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 unit
And data-signal, can be 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 is positive value, data-signal is negative value, when the first public voltage signal is negative
When value, data-signal is positive value, and equally, when the second public voltage signal is positive value, data-signal is negative value, when second public
When voltage signal is negative value, data-signal is positive value.
In this way, data-signal is -5V, public electrode when the public voltage signal of the corresponding input of pixel unit is+5V
Voltage difference with pixel point electrode is 10V, and when the public voltage signal of pixel unit input is -5V, data-signal 5V is public
Common electrode and the voltage difference of pixel point electrode are -10V.At this point, the voltage difference of the positive and negative amplitude of data-signal is 10V, drop 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.
