School Athletic Recognition Displays: Screen Wake Lock Release and Reacquisition Tests
A school’s athletic recognition display — a lobby kiosk showing hall-of-fame inductees, a hallway touchscreen cycling through championship banners, or a wall-mounted screen streaming seasonal awards — depends on one condition that is easy to overlook during setup: the screen must stay on. When a browser tab loses focus, a device suspends, or a visitor switches applications, the operating system’s power management will eventually dim or lock the screen. For a recognition display running unattended in a gymnasium lobby, that means the platform’s content goes dark precisely when visitors arrive expecting to browse it. The Screen Wake Lock API gives web-based recognition platforms a browser-native mechanism for requesting that the device keep the screen active — but the request is not permanent, not universal, and not immune to system conditions. The API releases the lock automatically when the document becomes hidden, and the platform must reacquire it when the document becomes visible again.
