Zhao Hui and mdaweb, here is the schematic.
The display should be a common anode display.
The 9.6v input shown in the schematic should not exceed the display max segment voltage.
I have shown the connection only for the 'a' segment. The patern just has to be repeated for the rest of the segments.
I have been using this circuit for some time now. It works great.
But the operating logic is a bit different.
Logic 1 on both p.1 and p.2 will turn segment 'a' on.
p.1=1 and p.2=1 --> seg'a' on
p.1=1 and p.2=0 --> seg'a' off
