Full Definition
Cabin displays have evolved from analogue floor-pointer gauges through segmented LED and dot-matrix modules to modern TFT LCD and OLED screens. Basic units show floor number (7-segment LED, 2.5–5 inch) and direction arrows; integrated multimedia displays (7–15 inch portrait TFT) show floor info, building announcements, news, weather, and advertising content managed via a CMS. Display brightness must be ≥200 cd/m² (basic) or ≥500 cd/m² (multimedia) to be legible in artificially lit cabins. The display interfaces with the elevator controller via CAN bus, RS-485, or LAN. For accessibility, EN 81-70 requires the floor position to be announced audibly (synthesised voice or pre-recorded audio) in addition to visual indication. High-refresh multimedia displays may use a separate media player PC fed content via the travelling cable LAN pair. Mounting height for the primary floor indicator is typically 1800–2100 mm AFF.
