Abstract
A landing door of an elevator system has a door leaf equipped with an integrated floor display that indicates to a person the floor at which an elevator car approaching the floor of departure is currently located. The door leaf of the landing door has a wall element made of sheet metal, the floor display having at least one controllable light source arranged behind the wall element, and a cover layer. The wall element has a display segment with a plurality of light passage openings, the light passage openings forming a perforated screen structure. The cover layer functions such that after the light source is activated to display the desired floor information, light from the light source penetrates through the light passage openings and the cover layer to the outside and when the light source is deactivated, the cover layer does not let light through to the outside.
