Does something power a Dot matrix?

There is the 4026 for a seven segment display counting 0 - 9. I was wondering if there's anything for a dot matrix counting 0 - 9?

1. eh, you could fake it by putting three LED's in parallel for each "segment" and then driving it with a 4026 as if it were a standard seven segment display. I am not aware of an off-the-shelf display driver for a dot matrix display, but 'm sure there is such a thing. Something I've seen done is to use a standard eprom as a "state machine" decoder. If you can build a truth table of what the inputs and outputs are, then you could program an eprom to do what you want. you might have to put a high current driver on the eprom output lines to generate enough current.
2. Maxim do 2 dot matrix display drivers, see http://pdfserv.maxim-ic.com/en/an/AN1033.pdf which can display many more characters then just digits
