Note 1 : Contrast ratio is definded as follows.
CR = LOFF / LON
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
follows.
VD = (Vth1+Vth2) / 2
Vth1 : The voltage VO-P that should provide 50% of the saturation level in the luminance at
the segment which the ON signal is applied to.
Vth2 : The voltage VO-P that should provide 50% of the saturation level in the luminance at
the segment which the OFF signal is applied to.
