NC
|
Not Connected.
|
7
|
VSS
|
Ground of Logic Circuit This is a ground pin. It acts as a reference for the logic pins. It must be connected to external ground.
|
8
|
VDD
|
Power Supply for Logic This is a voltage supply pin. It must be connected to external source.

IREF
|
Current Reference for Brightness Adjustment This pin is segment current reference pin. A resistor should be connected between this pin and VSS. Set the current lower than 10μA.
|
13
|
VCOMH
|
Voltage Output High Level for COM Signal This pin is the input pin for the voltage output high level for COM signals. A capacitor should be connected between this pin and VSS.
|
