Refer to the schematic diagram that Fig. 1, Fig. 1 are existing residual image improvement method.
Under normal circumstances, the solution of image retention includes purification liquid crystal molecule, optimizes optimum common electric voltage and use 0
Voltage shift of GTG etc..
As it is shown in figure 1, the core concept of the voltage shift of 0 GTG is the change by 0 GTG driving voltage so that dark space
There is also certain direct current residual, compensate the direct current residual in clear zone with this.Particularly, the clear zone of 255 GTGs is due to longer
The control of voltage it is driven so that the displacement of removable ion causes a certain degree of DC to remain in time, now, logical
Overregulate the driving voltage controlling 0 GTG dark space so that the voltage symmetry center Ux of dark space deviates common electric voltage Um, causes dark space
There is also a certain degree of DC residual.When observing the detection picture of 128 GTGs, owing to clear zone, dark space all exist the DC of equivalent
Residual so that do not observe obvious afterimage phenomena.U1, U0 represent the driving voltage of 255,0 GTG respectively, and Um represents common electrical

Calculate the summation of each absolute value, obtain the second positivity difference；And calculate the electricity of the data signal of negative polarity on all pixel cells
The absolute value of the difference between pressure and common electric voltage, and calculate the summation of each absolute value, obtain the second negativity difference；Calculate afterwards
Difference between two positivity differences and the second negativity difference, is compensated difference.
Owing to the global displacement amount of removable ion depends on that described exception is poor, therefore unusually poor with described when compensating frame
Numerical part closer to, and positive negativity is contrary, can preferably offset the mobile displacement of the removable ion that display frame triggers,
Namely display effect is more preferably.
Preferably, in order to improve display effect, according to described unusually poor numerical value, described compensation frame can be set with described

Compensate frame for offsetting removable ion overall offset amount under the display frame of default rate of scanning triggers.Specifically, permissible
The summation of above-mentioned difference is converted to grey decision-making.
Due to, the displacement that usual dark space may move ion is the least, does not results in significant direct current (DC) and remains, therefore,
We only need to increase by a frame and compensate picture, to make up removable ion displacement amount in the clear zone that image retention is corresponding.Certainly, it is assumed that image retention
Corresponding dark space there is also a certain degree of DC residual, now, whole image retention increases a frame and compensates picture, removable to make up
Ion displacement amount.

Eliminate ghost phenomena.
Such as, when having inputted 60 display frames at each second, compensations frame is inserted into and shows that frame end (can certainly be
The centre of display frame or the foremost input offset frame of display frame), this compensation frame makes removable ion produce and show before
Show the skew that side-play amount that frame triggers is in opposite direction, thus eliminate image retention.It is understandable that next second has inputted 60 and shown
When showing frame, it is also desirable to input offset frame；Namely according to showing that the periodicity of frame is to display frame input offset frame.
