LCD Driver
The Typ. values of the LCD drive voltage shown in the following table shift in difference of panel load (panel size, drive duty,
display segment number). Therefore, these should be evaluated by connecting to the actual panel to be used. Moreover, if
the display is uneven with a large panel load, connect a resistor (R1) between the V
SS
and V
C1
terminal. (It is necessary in
1/32 duty driving.)
