(Note) As operating voltage, (VDD-VO)V is charged to LCD.
Optimum operating voltage changes by viewing angle and temperature. Contrast can be changed by adjustment of VO, so please use LCD module at most suitable condition by each operating situation. When you fix the VO, please check using by actual set.
