What information do digital displays provide in modern elevators?

Digital displays in modern elevators serve a crucial role in user experience and safety by providing essential information to passengers. The correct answer reflects the comprehensive nature of what these displays communicate. They typically show the current floor number, which helps passengers keep track of their journey within the building. Additionally, they indicate the car's position, allowing users to see where the elevator is currently located, especially useful in multi-story buildings to manage expectations.

Furthermore, digital displays often include service notifications that inform users of any operational issues, maintenance alerts, or special instructions related to the elevator. This functionality enhances communication and safety, helping users to be informed about the elevator's status and any potential delays.

The other options are limited in scope and do not capture the multifunctionality of digital displays. For instance, focusing solely on temperature, weight capacity, or advertisements would miss the broader safety and navigational information that enhances the elevator experience.
