Description
Technical field
The present invention relates to the technical field of liquid crystal display, more particularly to a kind of liquid crystal display panel and its driving method.
Background technology
Liquid crystal display panel (liquid crystal display, LCD) has good image quality, small volume, lightweight, low drive
Dynamic voltage, low-power consumption, radiationless and relatively low manufacturing cost advantage, occupy an leading position in flat display field.Liquid crystal
Show panel including opposed color membrane substrates (color filter, CF) and array base palte (TFT array) and be interposed in both
Between liquid crystal layer (LC layer).
Due to the self character of liquid crystal, liquid crystal polarization can be made to its long-term DC voltage for applying a direction, it is normal to drive
Dynamic liquid crystal must apply AC field, and the voltage for putting on pixel electrode is alternately overturn relative to public electrode, i.e. pixel
The voltage of electrode changes back and forth between positive polarity and negative polarity, referred to as exchange driving (or reverse drive).Work as pixel electrode
Voltage when being higher than the voltage of public electrode, just referred to as positive polarity (+), when the voltage of pixel electrode is less than the electricity of public electrode
During pressure, just referred to as negative polarity (-).
To realize the reverse drive to liquid crystal, in data driving chip (source driver IC) to pixel electrode
When (pixel electrode) is filled with data voltage signal, public electrode (common electrode) has Fig. 1 and Fig. 2 two
Plant different voltage driving modes.
The voltage (dotted line C in ginseng figure) of public electrode is fixed always in Fig. 1, and the voltage of pixel electrode (is joined
Solid line P in figure) it is difference according to its GTG, do not stop to change up and down between each frame picture, in different frame (frame) picture
In face, for each GTG, the pressure difference absolute value of pixel electrode and public electrode is fixed, only positioned at liquid crystal two
The voltage at end, is once positive (positive polarity), and another time is negative (negative polarity), in order to avoids liquid crystal polarization and causes
The destruction of physical characteristic.Type of drive shown in Fig. 1, because the voltage of public electrode is fixed, referred to as common electrode direct current
Driving, also referred to as DC Vcom.
The voltage (dotted line C in ginseng figure) of public electrode constantly changes in Fig. 2, and the pixel electrode of different GTGs
Voltage (ginseng figure in solid line P) is also ceaselessly to change up and down, and the voltage of public electrode is when voltage is big than all display GTGs
Voltage is big, smaller than the voltage of all display GTGs in voltage hour, can equally reach and allow the pressure difference absolute value at liquid crystal two ends to fix
It is constant, and the effect that GTG will not also change, realize the purpose for the polarity of voltage reversion being applied on liquid crystal.Drive shown in Fig. 2
Flowing mode, because the voltage of public electrode is to change, referred to as common electrode exchange driving, also referred to as AC Vcom.
At present, the reverse drive of liquid crystal display panel is broadly divided into four kinds of modes, i.e. frame and is driven reverse (frame
Inversion), line inversion driving (row inversion), column inversion driving (column inversion) and dot inversion driving
(dot inversion).Wherein, frame reverse display is second-rate, and scintillation (flicker) is more serious；Row reversion and row are anti-
Phase inversion can improve scintillation for frame reversion；The display effect of dot inversion is optimal.
The array base palte of liquid crystal display panel is when making, and the public electrode of all sub-pixels is that whole face links together
(i.e. public electrode be whole face cover viewing area), and the type of drive of scanning drive chip (gate driver IC) be will be same
All thin film transistor (TFT)s (TFT) of row sub-pixel are opened, to allow data-driven IC to charge all sub-pixels of this line, and this
What the public electrode of all sub-pixels of a line was all connected together, if so being come from the voltage of the public electrode shown in Fig. 2
The type of drive changed is returned, display positive polarity and negative polarity can not be accomplished simultaneously on same a line sub-pixel.And column inversion
With the reversal mode of dot inversion, require that adjacent sub-pixel possesses different positive-negative polarities on same a line sub-pixel, because
The type of drive that public electrode voltages shown in this Fig. 2 change is only applicable to frame reversion and row reversion, be not suitable for column inversion with
Dot inversion.
As shown in figure 1, when the voltage of public electrode immobilizes, the ceiling voltage of pixel electrode needs to reach common electrical
More than twice of pole tension, and the offer of pixel electrode voltage comes from data-driven IC, if public electrode voltages are consolidated in Fig. 1
If 5V, then the operating voltage range that data-driven IC is provided will reach more than 10V.As shown in Fig. 2 working as public electrode
Voltage go when, if public electrode voltages are 5V to the maximum in Fig. 2, as long as data-driven IC maximum working voltage is also
Just can be with for 5V.The voltage magnitude of data-driven IC in Fig. 1 needed for DC Vcom type of drive is AC Vcom driving sides in Fig. 2
Twice needed for formula, therefore the purpose of province's power consumption can be realized using AC Vcom drivings.
Continuous improvement with consumer to the power conservation requirement of electronic product, the product that exploitation saves power consumption turns into panel factory face
The problem of facing.Panel factory attempts to reduce power consumption from driving.
As described above, if the purpose that traditional AC Vcom will realize province's power consumption can only be inverted with row reversion or frame, it is impossible to
Realize column inversion and dot inversion.If doing frame reversion, due to the limitation of the response time of liquid crystal, it is impossible to high-frequency drive, then human eye
It is easy to identify to arrive flicker；If doing capable reversion, Vcom must do one-shot change in every a line time, and Vcom power consumption can rise, together
When due in a frame time liquid crystal voltage constantly coupled, display quality can decline, for example contrast decline.
