I'm using the ICL7129ACPL to construct a simple 4-1/2 digit DVM. I looked over the application notes on FE LCDs on a similar post and noticed that it listed the FE0206 4-1/2 digit LCD as compatible with the ICL7129 so I went ahead and ordered one. I did not notice that the FE0206 has a single backplane listed (BP on pins 1 and 40) whereas the ICL7129 has three seperate backplanes (BP1, BP2, and BP3).
My question is:
can the three seperate BP pins on the ICL7129 be combined somehow to accomodate the single BP pin on the FE0206 or do I need to order a different LCD? If yes, how? Thanks in advance for any help you can offer.

You have to buy this..
Digi-Key - 153-1055-ND Varitronix - VIM-503-DP-FC-S-HV. Its part no is - VIM-503-DP-FC-S-HV from Varitronix.
Another could be Mouser Varitronix LCD Displays. Ensure you buy correct part number, It is a Triplexed (like Multiplexed) Display.
The LCD you have will not do, that you can use for some Microcomputer projects. Look at this page Arduino you can do more projects with these.
