Full screen refers to 4:3 aspect ratio, and will occupy the full screen of a CRT TV, it will be displayed on an LCD or similar 'widescreen' device in pillarbox (black bars on the sides) and may also be pan and scan. Widescreen generally refers to 16:9 which is closer to the cinematic original aspect ratio but may be letterboxed.
