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
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.
VO-P
1 / ( fF×A )
〈ON SIGNAL〉
