Hi Vincent,
Not quite sure what you are after.
Do you wish to censor something behind the LED sign by blotting it out or do you wish to use a sensor to perhaps turn the sign on as someone walks past?
Don't think you could do the first option because to make the entire perspec sheet turn a color it would need to be marked on the surface which would make it difficult to see through in the first place.
If you want the second then maybe something like this would do the job.

The Led's I used are 12 volt so it could all work off the same power supply.
Likewise you should be able to find sensors for light level, sound or even temperature as required.
Cheers
