about the COM signal mapping in different multiplex ratio N.
Under normal operation, this pin should be left opened and internal oscillator will be used after power
on reset.
6.10 RV
Ground reference of Vref.
6.11 CV
Ground reference of analog circuitry.
6.12 V
Ground reference of logic circuitry.
6.13 V
6.14 V
This is the most positive voltage supply pin of the chip. It can be supplied externally or generated by
the internal regulator.
6.15 V
LCD driving voltages. They can be supplied externally or generated by the internal bias divider. They
have the following relationship:
6.16 COM0 – COM63
These pins provide the row driving signal COM0 - COM63 to the LCD panel. See figure 5 and figure 6
6.17 ICONS
This pin is the special icons line COM signal output.
6.18 COL0 – COL103
These pins provide the LCD column driving signal. Their voltage level is V
6.19 CL
This pin is the external clock input for the device which is enabled by using an extended command.
Reference voltage input for internal DC-DC converter. The voltage of generated V
multiple factor (2X, 3X, 4X or 5X) times V
Note: Voltage at this input pin must be larger than or equal to V
