Description
Technical field
The present invention relates to a kind of driving method of liquid crystal indicator.
Background technology
Advantages such as liquid crystal indicator has gently, thin, short and small and little power consumption have been widely used in modernized information equipments such as notebook computer, mobile phone and personal digital assistant.
Usually, liquid crystal indicator comprises a liquid crystal panel for displaying images.This liquid crystal panel comprises a data drive circuit and a plurality of pixel cell that is arranged, and wherein each pixel cell comprises three sub-pixels.During the liquid crystal indicator display image, this data drive circuit provides gray scale voltage for the sub-pixel of each pixel cell in this liquid crystal panel.The gray scale voltage polarity of adjacent two frames of same sub-pixel is opposite, and the polarity of adjacent two sub-pixels is also opposite in the same frame.Simultaneously, the pixel cell of the normal GTG of each display image, its column direction with present black attitude in the line direction adjacent unit pixel and show, promptly its display effect is high gray.At present, this kind display device is used widely because of its good display quality, yet, when it showed particular image, the alleged crosstalk phenomenon of industry can appear.
Seeing also Fig. 1, is the display image synoptic diagram that crosstalk phenomenon appears in a kind of prior art liquid crystal indicator.The regional A of this display image one is positioned at the horizontal band-like zone in the middle of the display image, and this zone A center section is a rectangle high gray picture and two ends are same low grey menu.Zone around the A of this zone is an area B, the picture of the low grey menu same gray level at its demonstration and A two ends, this zone.When liquid crystal indicator shows this image, produce more serious crosstalk phenomenon, the low grey menu display brightness at belt-like zone two ends is different with the display brightness of same gray level picture in the area B among the A of this zone, and colourity is also different.
Seeing also Fig. 2, is the sub-pixel gray scale voltage polarity synoptic diagram that regional A and area B adopt the driving method of prior art liquid crystal indicator among Fig. 1.Liquid crystal indicator is an inversion driving mode, and wherein, three sub-pixels are formed a pixel cell.In the area B, data drive circuit is opposite for the gray scale voltage polarity that each sub-pixel and adjacent subpixels thereof provide, and provides high gray voltage along column direction and line direction adjacent unit pixel for the pixel cell of each normal gray scale voltage.This just makes data drive circuit for the gray scale voltage polarity that every capable sub-pixel provides is a minimum period with six sub-pixels, is regular and changes.Data drive circuit provides amplitude the gray scale voltage identical with polarity for the sub-pixel that is positioned at the area B at its belt-like zone two ends among the A of this zone, and the voltage of high gray is provided for the sub-pixel of intermediate rectangular part.
During normal the demonstration, the common electric voltage of regional A and area B is all V
ComYet, during the image of actual displayed Fig. 1, the common electric voltage of zone A and area B changes, and the common electric voltage in two zones is unequal, and reason is as follows: each sub-pixel comprises a data line (figure does not show), one scan line (figure does not show), a public electrode (figure does not show), a pixel electrode (figure does not show) and a thin film transistor (TFT) (figure does not show) in the liquid crystal indicator.There is memory capacitance between this public electrode and this pixel electrode, there are a large amount of stray capacitances in the source electrode of thin film transistor (TFT) and drain electrode between the data line of public electrode and liquid crystal indicator, in the pixel, as be present in gate leakage capacitance between the film crystal tube grid of pixel electrode and grid source electric capacity, grid and drain electrode between source electrode and living electric capacity etc. is omitted in the source between source electrode and drain electrode, therefore, during this pixel cell display image, the common electric voltage of public electrode is subjected to the pulling of above-mentioned capacitively coupled signal, and its current potential is offset.
Data drive circuit provides the gray scale voltage of opposed polarity according to an inversion driving mode for two adjacent in every capable sub-pixel in liquid crystal panel sub-pixels.This causes in the area B, and in the cycle that per six sub-pixels are formed, the positive polarity gray scale voltage sum that data drive circuit provides is less than the gray scale voltage sum of the negative polarity that provides with data drive circuit in one-period.Therefore, in the whole zone of area B, data drive circuit for each gray scale voltage sum of providing of row sub-pixel less than zero.In the liquid crystal indicator displayed map 1 during image, the common electric voltage V in the area B
Com2Be subjected to the coupling of electric capacity, the gray scale voltage that data drive circuit provides causes common electric voltage V less than zero
ComPulled down, and then make the actual common electric voltage V of area B
Com1Less than common electric voltage V
Com
Among the A of zone, because of being the high gray viewing area in the middle of it, data drive circuit is repealed by implication for positive polarity gray scale voltage and negative polarity gray scale voltage that this each sub-pixel of high gray viewing area provides, and its summation is zero.And the gray scale voltage that data drive circuit provides for the sub-pixel of regional A two end portions is consistent for the gray scale voltage polarity that the sub-pixel of this area B provides with data drive circuit, and this part gray scale voltage sum is also less than zero.Since among the regional A only the gray scale voltage sum of two end portions less than zero, and the gray scale voltage sum of middle high gray viewing area equals zero, therefore, among the A of zone in every capable sub-pixel, numerical value after each sub-pixel gray scale voltage summation is less than the numerical value after the every capable sub-pixel gray scale voltage summation of area B.And then the common electric voltage V of each row sub-pixel correspondence among the regional A
Com1Be subjected to the capacitive coupling effect, with common electric voltage V
ComDeparture degree less than the common electric voltage V of area B
Com2Departure degree.
Because this liquid crystal indicator is a counter-rotating liquid crystal indicator, in ensuing frame, when data drive circuit provided opposite polarity gray scale voltage for each sub-pixel, the common electric voltage situation and the above-mentioned situation of this zone A and area B were similar, and difference only is this common electric voltage V

Com2Be higher than this common electric voltage V

In the driving method of above-mentioned liquid crystal indicator, data drive circuit provides polarity different gray scale voltages for every two adjacent sub-pixels in every capable sub-pixel, it is non-vanishing to form the gray scale voltage sum that six sub-pixels of one-period provide in every capable sub-pixel, the gray scale voltage sum of every capable sub-pixel is also non-vanishing, corresponding common electric voltage is influenced by the gray scale voltage sum of this sub-pixel and is pulled, and makes common electric voltage inaccurate.Simultaneously, the influence that the common electric voltage of zone A and area B is subjected to is different, and causes its common electric voltage difference, and then when causing liquid crystal indicator to show image shown in Figure 1, different among the A of zone with the GTG of image actual displayed of same GTG in the area B, serious crosstalk phenomenon finally appears.In addition, the image that crosstalking appears in liquid crystal indicator is not that only Fig. 1 is a kind of, usually, presents large tracts of land with in the gray scale image, and the image that exists block different GTG to show all can produce crosstalks.
Summary of the invention
The problem that occurs crosstalking when driving the liquid crystal indicator display image for the driving method that solves the prior art liquid crystal indicator is necessary to provide a kind of driving method that can make the liquid crystal indicator that crosstalk phenomenon eliminates substantially.
A kind of driving method of liquid crystal indicator, it comprises: a liquid crystal indicator is provided, and this liquid crystal indicator comprises a data drive circuit and a plurality of sub-pixel that is arranged; Provide the polarity gray scale voltage of cycle variation spatially by this data drive circuit for every capable sub-pixel, and the gray scale voltage sum in each cycle on the space is equalled zero.
Compared with prior art, in the driving method of above-mentioned liquid crystal indicator, this data drive circuit provides that the sub-pixel gray scale voltage sum in each cycle equals zero to the space, and the gray scale voltage of average each sub-pixel of each cycle is zero on its space that provides.When liquid crystal indicator showed each frame image, the gray scale voltage of each cycle sub-pixel did not have pulling function to common electric voltage on the space, and the common electric voltage of every capable sub-pixel is not subjected to the pulling of gray scale voltage basically yet, and keeps a stability number.This common electric voltage is stable and then when making the liquid crystal indicator display image, and crosstalk phenomenon is eliminated basically.

This data drive circuit is one-period with four frames for being one-period with adjacent 12 sub-pixels on the gray scale voltage polarity space that sub-pixel provided in each cycle in the delegation then on the time.During with liquid crystal indicator actual displayed image, data drive circuit is same one-period on the space, and the gray scale voltage polar arrangement mode that per four frame sub-pixels provide on the time is an example, advances row and elaborates:
When liquid crystal indicator shows first two field picture, this data drive circuit provides the gray scale voltage of identical polar for same group two sub-pixels, and the gray scale voltage polarity difference that provides for the sub-pixel of adjacent set, if the gray scale voltage polarity of two sub-pixels is all "+" in promptly same group, two sub-pixel gray scale voltage polarity of its adjacent set are all "-".Like this, this data drive circuit for the gray scale voltage polarity that the sub-pixel in each cycle provides from this sweep signal input end is from the near to the remote: " ++--++--++--".
When showing second two field picture, this data drive circuit reverses the gray scale voltage polarity of first sub-pixel in each unit, and makes the second sub-pixel polarity of each unit identical with the polarity of its first frame.Like this, this data drive circuit for the gray scale voltage polarity that the sub-pixel in each cycle provides from this sweep signal input end is from the near to the remote: " ++--++--++-".
When showing the 3rd two field picture, this data drive circuit reverses for the gray scale voltage polarity that second sub-pixel of each unit provides, and the gray scale voltage polarity that provides for first sub-pixel of each unit keeps identical with the gray scale voltage polarity of its second frame.At this moment, this data drive circuit for the gray scale voltage that the sub-pixel in each cycle provides from this sweep signal input end is from the near to the remote: "--++--++--++ ".
