Assuming that the typical driving waveforms shown below are applied to the LCD

Panel at 1/A Duty - 1/B Bias (A: Duty Number, B: Bias Number). Driving voltage

is definded as follows.

= (Vth1+Vth2) / 2

Vth1: The voltage V

O-P

that should provide 70% of the saturation level in the

luminance at the segment which the ON signal is applied to.

Vth2: The voltage V

O-P

that should provide 20% of the saturation level in the

luminance at the segment which the OFF signal is applied to.
