You're going to have to define "large". 2 inches? 2 feet? 2 yards?

Try this for size

Or perhaps this?
Not sure how many arduinos would be required to run it, though.

sorry i forget to define size such as 120*7 pixel

120*7 pixel

Did you really mean 120 pixels along one edge and 7 pixels along the other? That's a pretty unusual requirement.

Nah, just 15 8x8 matrices. Drive  with 15 TPIC7219s, one per matrix. Use SPI, send out 120 bytes of data from an array to update the entire thing at one time.
