A display of what? How large, what resolution, what colors... ?
Do you want to make the equivalent of a big Tv screen?
A simple LED matrix looks like THIS - This is an 8 x 8 one. Each individual LED can be turned on by setting its corresponding row pin HIGH and its column pin LO. To give the impression of a continuous display, the driving circuitry would do this very quickly for each LED which needed to be lit so it appears to be constantly on (due to persistence of vision). If you're only trying to make a simple lit sign, post more details.
