LG 55EJ5K-B – 55-inch FHD Wallpaper OLED Signage

Product Overview

The LG 55EJ5K-B is a 55-inch FHD Wallpaper OLED signage display designed for premium, design-forward commercial spaces. Its self-emissive OLED panel measures under 5 mm deep and weighs 14.3 lbs, mounting nearly flush to the wall for a feature installation in lobbies and boardrooms. With 150,000:1 contrast, perfect blacks, and a 0.9 mm even bezel, this commercial OLED signage display renders content with depth that backlit LCDs cannot match. A separate signage box houses the webOS 4.0 media engine and connections, keeping the on-wall profile minimal.

Product Description

This ultra-slim wallpaper OLED display pairs a 1,920 x 1,080 self-emissive panel with a 120 Hz refresh rate, 1 ms response, and BT.709 120% color gamut for smooth, vivid motion content. The panel connects to an external signage box via flat flexible cables, separating the electronics from the display so the screen sits flat against the wall using the included wall fixers rather than a standard VESA mount. Running webOS 4.0 with 16 GB of storage, it supports SuperSign CMS, local content scheduling, gapless playback, and screen rotation for portrait or landscape layouts. For AV integration, it offers HDMI and DisplayPort inputs with HDMI/DisplayPort daisy chaining, RS-232C and LAN control with loop-through, and Crestron Certified compatibility. TAA compliance supports government and public-sector procurement, while a tile mode allows expandable multi-panel arrangements. For other premium 55-inch options, compare the 55-inch UH5N-E UHD signage display or the high-bright 55-inch XS4J-B window display.
