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 = LOFF / LON)
LON : Luminance of the ON segments
LOFF : Luminance of the OFF segments
Measuring Spot:0.9mmφ
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 VOD
VOD=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
VOD is definded as follows.
VOD = (Vth1+Vth2) / 2
Vth1: The voltage VO-P that should provide 70% 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 20% of the saturation level in the
luminance at the segment which the OFF signal is applied to.
