Hello Tal, Spehro and Vasile, Actually I think that building a 7 seg display with discrete 5mm LEDs would be the better option for this project. Maybe even 5x7 displays with 5mm LEDs wich I think would be cool, but I will have to wait for the client to tell me what HE wants. Thank you for your replies and if I get this project aproved I'll keep you informed.
