• Duty command setup example
1. Duty 1/88 When 1 (COM4 to COM7) is specified as the start point (block)
Display area COM4 to COM91
2. Duty 1/68 When 26 (COM104 to COM107) is specified as the start point (block)
Display area COM104 to COM131 and COM0 to COM39

SEG132, COM80+COM80), the same duty must be used on the master and slave. Otherwise, display contrast will
be different on the master and slave. When you want to disable display on either the master and slave, use the display
