New Series 57 Multi-Legend Display.

For intuitive status information in public transportation.

Olten, Switzerland, January 2022 – EAO, the expert partner for innovative, intuitive and reliable Human Machine Interfaces (HMIs), sets again a new standard in public transport with its innovative and market leading Series 57.

Public transportation applications need intuitive indicators that use symbols which are easily identifiable and visible in all conditions. For example, a passenger needs to be able to quickly identify from a distance if a toilet is vacant, occupied or out of order so that they do not unnecessarily waste time waiting or searching for the facilities. In the event of a fire, it is especially important for the alarm symbol to be quickly identifiable. And there are numerous other indicator applications that passengers can benefit from. The Series 57 Multi-Legend Display is intuitive in use, offers flexibility in operation, is easy to maintain and meets all relevant public transportation standards.


  • Up to 18 customisable symbols per display
  • Excellent visibility and wide viewing angle
  • Environmentally adaptive sensor for display brightness
  • Modern design with low back panel depth
  • Complies with relevant standards
With a 3" TFT display, integrated sensor for adapting the display brightness and a wide viewing angle, this display has been designed from the ground up to be easily identified. Aside from offering optimum visibility in all lighting conditions, the brightness sensor also optimises the service life of the device by ensuring that the illumination is never brighter than it needs to be. The clear visibility of up to 18 customisable symbols on each display builds upon the large number of combinable display colours and the high display contrast. The symbols displayed can be shown with a resolution of up to 432 x 432 pixels and can be uploaded to the device, by using the Multi-Legend Display programming kit.
