Abstract
A method of eliminating liquid crystal declination rectifies one pixel gray scale or at least one adjacent pixel gray scale to ensure a potential difference between a control electrode and a pixel electrode to be read into the pixel is lower than a minimum potential difference. Wherein, value of the potential value is in connection with the gray scale of the adjacent pixel. The minimum potential difference increases along rise of the pixel gray scale. Upon completion of the gray scale rectification, the potential difference as above is arranged between the control electrode and the pixel electrode. As the pixel electrode is positive, the potential of the control electrode is higher than potential of the pixel electrode. As the pixel electrode is negative, the potential of the control electrode is lower than potential of the pixel electrode.
Description
Technical field
The present invention relates to a kind of LCD (Liquid Crystal Display, LCD), particularly a kind of method (disclination of liquid crystalmolecules) of eliminating LCD disclination.
Background technology
Fig. 1 is a kind of sectional view of liquid crystal panel, and this liquid crystal panel is BBVA (Bias-Bending Vertical Alignment) pattern.Fig. 1 only draws a pixel (pixe1) 10.As shown in Figure 1, this kind liquid crystal panel comprises a colored filter (color filter) 11, one liquid crystal layer (liquid crystal layer) 12 and one active matrix substrate (active matrixsubstrate) 13.This colored filter 11 and this active matrix substrate 13 have a transparent substrates (transparent substrate) 111 and 131 respectively.Comprise a public electrode (common electrode) 112, one pixel electrode (pixel electrode) 134 and one control electrode (control electrode) 133 in the pixel 10.One insulation course (insulation layer) 132 is between this pixel electrode 134 and this control electrode 133.The current potential of this pixel electrode 134, this control electrode 133 and this public electrode 112 is respectively with V

If have arbitrary rule not to be satisfied in above-mentioned three rules, liquid crystal 121 will turn to wrong situation (shown in Figure 1B block), causes transmittance (transmission ratio) to descend.The situation that above-mentioned liquid crystal changes wrong direction can be referred to as " LCD disclination (disclination) ".The problem that LCD disclination caused comprises low-transmittance, the reaction time is long and liquid crystal layer 12 instabilities.
U.S. Patent Publication No. US 2005/0083279 A1 has disclosed multiple liquid crystal panel based on the described liquid crystal panel of Fig. 1.Yet the disclosed technology of this patent only can satisfy above-mentioned first and second rule, and can't guarantee to follow above-mentioned the 3rd rule.With Fig. 1 is example, and the technology that this patent is exposed only can determine the potential difference (PD) Δ V between this control electrode 133 and this pixel electrode 134 by the GTG value of a plurality of neighborhood pixels of pixel 10, between the GTG value of potential difference (PD) Δ V and pixel 10 and onrelevant.
Fig. 2 is the actual luminous situation of several pixels on the disclosed liquid crystal panel of US 2005/0083279 A1.With pixel 202 is example, and the potential difference (PD) Δ V of the control electrode of pixel 202 and pixel electrode is that control method is Δ V=|V by the GTG value decision of two neighborhood pixels 204 of pixel 202 and 206

Summary of the invention
Fundamental purpose of the present invention is the potential difference (PD) size of a control electrode and a pixel electrode in the control pixel, is enough to avoid above-mentioned image smear (zone 208 as shown in Figure 2) to take place to guarantee this potential difference (PD).The present invention has disclosed a kind of new method of eliminating LCD disclination, and this method can satisfy three mentioned rules of prior art simultaneously.
In the present invention, will be written into a potential difference (PD) between a control electrode of a pixel and the pixel electrode, this potential difference (PD) size is relevant with the GTG value of at least one neighborhood pixels of this pixel.Three rule mentioned according to prior art, the potential difference (PD) of this control electrode and this pixel electrode must be poor greater than a minimum level.The GTG value of this pixel is big more, and then this minimum level difference must be big more.The disclosed method of the present invention comprises the GTG value of proofreading and correct this pixel and above-mentioned neighborhood pixels, and is poor greater than this minimum level to guarantee this potential difference (PD).After having proofreaied and correct the GTG value, make the potential difference (PD) of this control electrode and this pixel electrode equal this potential difference (PD).If the polarity of this pixel for just, makes the current potential of this control electrode be higher than the current potential of this pixel electrode.If the polarity of this pixel for negative, makes the current potential of this control electrode be lower than the current potential of this pixel electrode.After the potential difference (PD) of determining this control electrode and this pixel electrode equals this potential difference (PD), reset the current potential of this pixel electrode according to the GTG value behind this pixel correction.The current potential of this control electrode must be simultaneously along with the current potential of this pixel electrode changes, with the potential difference brought that makes this control electrode and this pixel electrode in above-mentioned potential difference (PD).
The invention also discloses another kind of embodiment.This kind embodiment is at first according to the characteristic and the type of drive of liquid crystal panel, and a maximum gray that calculates between a pixel and its neighborhood pixels is poor.Potential difference (PD) between the control electrode that the present invention desires to write this pixel and the pixel electrode is relevant with the GTG value of this neighborhood pixels.The GTG value of this neighborhood pixels is lower, and this potential difference (PD) that is then produced is lower.If the GTG value of this neighborhood pixels is little than the GTG value of this pixel, and the GTG value difference of this neighborhood pixels and this pixel is apart from poor greater than this maximum gray, then the above-mentioned potential difference (PD) that is produced according to the GTG value of this neighborhood pixels can be too small, is not enough to prevent that LCD disclination from taking place.Therefore, before driving this pixel, the GTG value of this pixel and above-mentioned neighborhood pixels is proofreaied and correct in meeting of the present invention earlier, and when bigger than the GTG value of this neighborhood pixels, the gap of the GTG value of this pixel and this neighborhood pixels is poor less than this maximum gray with the GTG value of guaranteeing this pixel.
