sources during turn on/off. It gives the OEL panel enough time to complete the
action of charge and discharge before/after the operation.

CI
& V
DDIO
2. Send Display off command

(when V
CC
is stable)
7. Send Display on command

3. Normal segment and display data column and row address mapping (SEG0
mapped to column address 00h and COM0 mapped to row address 00h)
4. Display start line is set at display RAM address 0
5. Column address counter is set at 0
6. Normal scan direction of the COM outputs
