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 ON / LOFF
LON : Luminance of the ON segments
LOFF :
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 OD
V OD= V CC-V ADJ-V BE
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).
