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
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 VD
VD=VCC-VADJ-VBE
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
VD is definded as the voltage VO-P when the contrast ratio (CR=LON / LOFF) is at its
maximum.
