user3630: I got this 8-unit, 7-segment, 2-digit display board with 24 pins and I am wondering how I can interface with this from my Arduino Uno.
The board is labeled ROHM BP-006LH-GC and it has 8 units of the LB202VL LED display. Please see these photos of the board:



I found the datasheet for the LB202VL unit and I have been trying to make an independent unit on the board to work but I haven't been successful in setting its display.
The datasheet for the LB202VL unit can be found here: http://pdf.datasheetarchive.com/datasheetsmain/Datasheets-27/DSA-525461.pdf
Can anybody help me explain how I can work with this and set the display from my Arduino? After having attempted a few times I feel a little lost with this so any help would be greatly appreciated!

user6875: 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.
