    Hi there,

    I'm looking for a VERY small 1 line LCD display - approximately 9 chars long.

    Size of the digits should be no larger than 6mm and would prefer something on the order 3 mm. No backlight - prefer black on grey.

    Thanks!

    Salvage one from a calculator.

    This seems easier said than done. That is exactly what I tried to do - but the connection point is pretty funky - some sort of
    conductive rubber that lays on the PCB. While intriguing and fun to play with - I need something a little more robust to mount in
    my case. It is about the right size though.

    Any other thoughts?

    Thanks!

  4. I read in sci.electronics.design that ChronoFish <>
    wrote (in <[email protected]>) about '(sub) miniture LCD',
    That's how they normally are connected. The idea is to mount the device
    resiliently and without any bending force developing.
    The conductive rubber connectors are quite robust (think of the hard
    treatment calculators often get) but the mounting does need some careful
    dimensioning.

    Right, plus the brittleness of the glass and the size of the CTE mismatch
    with FR-4 board causes massive breakage or peeling of the metal pads under
    temperature cycling.

    That's a 'zebra strip'. I've had buffalo burgers and clam strips, but those
    zebra strips are tricky....
