You omitted to explain what your problem is.

just now i have started to work with dot matrix.
Some of my friends suggest to use 74LS595 to drive Column so i purchased PCB related to 74595 but i don't know how to drive row and how much current it takes

So suggest a circuit diagram

Well, it's an 8-bit shift register, so you'd need 48 of 'em to simply drive 24 x 16.
Still sound good?

Did you see this?
