The meaning of values inside data RAM with respect to the gray scale level is best to be illustrated in an
example below.

This block is used to derive the incoming power sources into the different levels of internal use voltage
and current. V
driving voltage for segments and commons. I
Segment drivers deliver 396 current sources to drive OLED panel. The driving current can be adjusted
from 0 to 200uA with 256 steps. Common drivers generate voltage scanning pulse.
