    Hi All,

    I'm trying to make a large 7 segment display with 4 separate digits. The
    display has to be about 5" high, so there will probably be multiple LEDs per
    segment (I was goint to use rectangular high effeciency LEDs for the
    segments). Alternatively there may be manufacturers of large 7 segment
    displays out there. Does anyone have any thoughts on driver chips for
    multi-LED segments, or manufacturers of large displays? I have an AVR micro,
    so I2C or SPI control would be ideal but any form of interface can be done.
    The uC runs at 3.3V but I have a 12V supply available. Power is a
    consideration as the whole thing will be powered from a rechargeable lead
    acid battery.

    Any comments appreciated!

    Er, just seen the post about a clock requiring a large display. I've noted
    the comments!
