Do you have any sources on that? The only thing I could find was that some parties want to ban digital billboard in the city of Zurich (not the whole canton).
Sorry, I had to clarify that the final decision has not yet been made. The city still approves digital billboards [0].
In Geneva, the debate has been going on for some time. There, I think since 2021, digital billboards should be banned, but in the latest votes there is the counter-movement to keep the billboards [1].
