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.
