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 = LON / LOFF)
LON : Luminance of the ON segments
LOFF : Luminance of the OFF segments
Measuring Spot : 3.0mmφ
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 VOD
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
VOD is definded as the voltage VO-P when the contrast ratio (CR=LON / LOFF) is at its
1 / ( fF×A )
1 / fF
( B-2 )×VO-P / B
