Strange display C63.396.208(I-208) - any info on this?

[Manuel Azevedo]

Hi guys,

Does any of you have any information on this strange displays?
I ordered 6 to test, but I couldn't find much information about them - it seems that they turn on at 200V, but I'm not sure.
The strange "alien" looks make these displays really interesting.

Here you can find some information: http://www.155la3.ru/electroluminescent.htm

You should current limit them when using them as they will otherwise easily have flash-overs, if driven the wrong way, destroying the segments and the tiny wires connecting the elements inside the case.

Thank you Martin.

It’s more than I’ve found so far!

I’m curious with what I can make with this.

 

Thanks

 

Manuel

Very neat display? Where did you get them? Looked on fleabay, didn't see
them. I want some! :-)

I bought 4 of these last year on a whim because they are SO unusual

Problem is, electroluminescent displays have a rather short lifespan, on the order of a few hundred hours. Not a good choice for a 24/7 clock.

They operate on low-frequency AC, on the order of a few hundred Hz. Basically, the capacitive current energizes the phosphor material to emit visible light. They *will not* operate on DC.

Also, you must not operate them on square-waves, as the high dv/dt will result in excess current. I plan to use a triangular wave, which results in constant current.

I discourage you from using 50/60Hz AC from the mains, as it would require higher voltage to get illumination, which could cause breakdown

I measured the capacitance of my display units (posted below), and as expected, larger segments have higher capacitance

It's another project on the long to-do list.....

Pin	Cap (pF)
2	250
3	460
4	170
5	215
6	196
9	94
10	98
11	213
12	218
13	178
14	422
17	402
18	235

There’s this one still left:

Yes, I’ll keep them also for a long term project J

Thank you for your notes!

Dang, was gone when I got there. Thanks though

If you search the part numbers listed at the bottom of the page at the link from the first reply, they will show up on fleabay. Example http://www.ebay.com/itm/ITEL2-G-2-Single-electroluminescent-lights-BLUE-VFD-Russian-RARE-1-pcs-/182436477279?hash=item2a7a0fb95f:g:hR0AAOSwaB5XnkDs
