I did not know the name myself, but in fact the very same word is used in the British advertising world: Digital totem or advertising digital totem, a type of structure presenting a wide display area at its top for advertisements.

Totem advert guidance
Back to 'buzz'
The University’s 12 digital totem screens, located at key access points across campus, offer a great navigational tool for students, staff and visitors to campus, as well as providing useful up-to-date information to users.
When they are not being interacted with, the totems are ‘idle’ and can act as displays for up to four electronic adverts at any given time. These adverts are managed by the Communications and Reputation team in External Relations.
How can I have an advert on the screen?
If you would like an advert displayed on the totems, your advert must be relevant to a wide cross-section of the University.
