webOS is the Linux-based operating system developed by LG that powers LG professional signage displays, smart TVs and select IoT devices. webOS is one of the three dominant SoC platforms in digital signage alongside Samsung Tizen and Philips Android.

A webOS-based display runs signage software directly on the screen with no external player — making it a clean fit for lobbies, retail, hospitality and any indoor environment where minimal hardware footprint matters. Livesignage is certified across the supported webOS versions in active commercial use, with native applications that integrate with LG display-level features for monitoring, scheduled wake/sleep, and remote diagnostics.
