As shown in Figure 1, the core concept of the voltage shift of 0 grayscale is the variation by 0 grayscale driving voltage so that dark space
There is also certain direct current residual, the direct current that clear zone is compensated with this remains.Particularly, the clear zone of 255 grayscale is due to longer
The control of voltage is driven in time so that the displacement of removable ion causes a degree of DC to remain, at this point, logical
Overregulate the driving voltage of 0 grayscale dark space of control so that the voltage symmetry center Ux of dark space deviates common voltage Um, leads to dark space
There is also a degree of DC residuals.When observing the detection picture of 128 grayscale, because there is the DC of equivalent in clear zone, dark space
Residual so that do not observe apparent afterimage phenomena.U1, U0 indicate that the driving voltage of 255,0 grayscale, Um indicate common electrical respectively
