    I think you want to drive a dot LED-matrix-display.
    Try http://www.maxim-ic.com search MAX6952 or MAX6953 a
    4-Wire Interfaced, 2.7V to 5.5V,
    4-Digit 5*7 Matrix LED Display Driver.

    The IC is a little expensive, an other solution is combined Hard/Software:
    You need some SIPO IC's (Serial input parallel output)
    for Example 74HC4094.

    Similar solutions could be found in schematics of "rolling advertisement Display's"

    I have developed a 6-Digit-didital-clock with this kind of driving. I have a schematic and an assembler-file. If it is of any help for you, i will post it. Hope it is posible to attach a PDF-File to this forum.

    Best regards
