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.

Note 1 : Contrast ratio is definded as follows.
CR = L
OFF
/ LON
L
ON
: Luminance of the ON segments
L
OFF
: Luminance of the OFF segments
Note 2 : The time that the luminance level reaches 90% of the saturation level from 0% when ON
signal is applied.
Note 3 : The time that the luminance level reaches 10% of the saturation level from 100% when OFF
signal is applied.
Note 4 : 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 volt age 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 volt age V
O-P
that should provide 50% of the saturation level in the luminance at
the segment which the OFF signal is applied to.
