意味

Screen sharing — the feature of showing your screen to others during a video call or meeting.

A compound of 画面 (screen) and 共有 (sharing), 画面共有 became essential workplace vocabulary with the rise of remote work. It is used both as a noun and verb (画面共有する). The term carries a hint of anxiety for many workers — the fear of accidentally sharing private browser tabs, messages, or embarrassing desktop wallpapers has become a relatable modern workplace fear.
