Note 1 :
Voltage (Applied actual waveform to LCD Module) for the best contrast. The
range of minimum and maximum shows tolerance of the operating voltage. The
specified contrast ratio and response time are not guaranteed over the entire range.

The time that the luminance level reaches 10%of the saturation level from
100%when OFF signal is applied.

Definition of Driving Voltage V
D
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 V
D
is definded as follows.
V
D
= (Vth1+Vth2) / 2
Vth1 :The voltage V
O-P
that should provide 50%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 50%of the saturation level in the
luminance at the segment which the OFF signal is applied to.
