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 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 V
D
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 V
D
 is definded 
as follows. 
V
D
 = (Vth1+Vth2) / 2 
Vth1 : The voltage V
O-P
 that should provide 50% of the satulation level in the luminance 
measured at
θ
= 10
 
, 
φ
=270
 
 on the segment which the ON signal is applied to. 
Vth2 : The voltage V
O-P
 that should provide 26% of the satulation level in the luminance 
measured at
θ
= 40
 
, 
φ
=270
 
 on the segment which the OFF signal is applied to.
