The term bezel has a modern use in which it describes the visible border structure surrounding a display surface. Example: "This monitor has a 1cm bezel, so if you place two of them next to each other there is a noticeable gap between screens." It does not only apply to monitors, but to any 'dead space' around display surfaces. Smartphones and tablet computers also are referred to as having 'bezels' if there is dead space (no display) around their edges. It's possible for bezels to have touch controls on them, so having input functions does not change the fact that such areas are considered a bezel.
