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.
VO-P
1 / ( fF A )
ON SIGNAL
1 / fF
( B-2 ) VO-P / B
