*1:  When the number of liquid crystal display lines is changed, the liquid crystal drive voltage from which 

optimal contrast is obtained changes.    To avoid the problem of the display, for example, the display turns 
black for an instant, place in the power save mode in the above sequence and turn off the display once.   
Then set to obtain the optimal liquid crystal drive voltage before displaying again.   

*2:  To change the liquid crystal drive voltage, discharge the capacitor for holding the voltage once. 
*3:  Set to the number of frame frequency that won’t cause display problem such as a flicker. 
*4:  Set to the number of n line inversions that won’t cause display problem such as a flicker.

Secure the discharge time 
of the capacitor for 
stabilizing the liquid crystal 
voltage until V

3

 < 15V is 

attained. Since the 
discharge time depends on 
the state of external 
circuits, including the V

3

 

voltage before discharge 
and the capacity value of 
the capacitor, be sure to 
secure the time with 
sufficient margin after 
evaluation.

Change external LCD voltages to target voltages.
