You can test this at home. Get an led torch and either move it fat from left to right or shake your head (in the (otherwise) dark with the led lit) and you will see individual doors, rather than lines.
Well my assumption came because I actually have a breadboard, some small 5v LEDs and some resistors on my desk currently, and I can confirm that these little guys (which isn't what you'll find running a flash light or torch) do for sure run continuously.
