How to use ROHM LB202VL display (on BP-006LH-GC board) with Arduino?
I have a similar display, and I found the wiring by inspection and trial and error:

The display consist of 8 pairs of digits (LB-202VL, common cathode).

If contact points are numbered from 1 to 24 from left to right then
the common cathodes for the digits D1-D16 and the segments D.P. and 'a' - 'g' are noted below.
If you i.e. connect 1 to GND and 7 to + then segment 'c' of the first digit will be on. You have to multiplex the digits in order to use it.
