Oh, yes, now I understand, I looked at the stripes under a magnifying
glass and the conducting strips are very narrow, so it doesn't matter
how it's lined up, very neat! (who invented this thing). It does look
like it has to be compressed quite a bit, the rubber strip is quite a
bit thicker then the space between the LCD glass and pcb board, I still
have to think of good way to prototype these parts, there doesn't seem
to be a easy way to verify the connection, thanks

You don't need to line up the zebra stripe connectors, you just have to line
up the PCB with the display. Put enough pressure on the PCB and display to
make contact. The stripes are alternate conductor and insulator so as long
as your pads have enough spacing they won't short out.

I'm looking for a small LCD, nothing special, just three digits, but
small, like the kind you find in those oral digital thermometers or
small digital watches. All the standard LCD's I can find are quite big,
the one I need is about .3 x .7 inches, about the size of a 14 pin IC.
I can find LED's type displays in this size, but not LCD's, I need a
low power display.
I did buy a $2 thermometer at walmart and broke it open, the LCD just
fell out and therefore is quite useable, however, it uses a rubber type
connector(zebra strip I guess they call them), I'm not sure just how to
construct a prototype device that uses this connector, the PCB board
looks easy, just pads that are gold plated, but it seems to require a
custom mechanical fit, could I somehow just glue it down for a
prototype? How do you line up the zebra strip?
thanks in advance!
