Are you trying to pre-place the LEDs on a board so they spell what you want even when turned off, or are you wanting to make this with a scrolling matrix/banner type display?

The first is relatively simple, LED series parallel array wizard. Get LED current and Vf from the datasheet.

The second (scrolling), is not so simple.

Someone elses attempt to do something similar, though it may be a different concept than yours.
