The actual public electrode voltages of liquid crystal display shift in standard public electrode voltages, if being driven using standard public electrode voltages
Hydrodynamic crystalline substance screen is shown, then will result in the difference of the pixel electrode voltage of practical public electrode voltages and positive polarity not equal to real
The difference of the pixel electrode voltage of border public electrode voltages and negative polarity is eventually led to before and after pixel electrode voltage switch polarity
The grayscale shown is different, and user may feel that screen in flicker (flicker), public electrode voltages offset in use
It is bigger, differ bigger between two differences, gray scale variation amplitude is bigger, and the flicker level experienced during user's use is stronger
It is strong.
It just can not be changed after terminal, manufacture since initial code is fixed storage in the prior art, so cannot solve
Certainly because of the standard public electrode voltages being arranged in initial code and liquid crystal display caused by actual public electrode voltages difference
Flicker.
