LG 55EJ5K 55″ Flat OLED Signage

Artistic Space beyond Display, LG Wallpaper OLED Signage

Absolute Black

Equipped with over 8 million self-lighting pixels operating individually, LG OLED Signage reproduces absolute blacks with no light bleed and offers infinite contrast.

Rich Color

LG OLED Signage provides richness in all colors, bringing colors to life with great accuracy and vividness.

N × N Expandable Screen Size

By tiling up displays horizontally and vertically, the screen size can be as large as users want. Expansive, large screens are more effective at moving viewers by providing an incredibly immersive viewing experience.

LAN Daisy Chain Management

A LAN daisy chain is supported, allowing you to execute commands to control and monitor the displays and even update their firmware.

Wall Fixers Optimized for Simple Tiling

The overall installation process of the wallpaper OLED has gotten much easier. Once the dedicated wall fixers are driven into a wall, a display can be easily hung on them. Video wall tiling has become more convenient, thanks to its front installation feature, which departs from the conventional sidesliding method.

Enhanced Flexibility of Cables

As a result of in-depth consideration of usage scenarios, improvements have been made to the flexibility of common cables connecting the display to the signage box. These new cables are pliable enough to be easily embedded in a wall or other structures.

Splendid Design

LG’s OLED technology unlocks the new worlds of design flexibility with unbelievably lightweight and slim display. The advantages the OLED display brings are countless from the easier installation to a sleek look.

Hide in Plain Sight

The subtle edge of the wallpaper OLED totally blends in with the wall, giving audiences the sensation that content is being played directly within the wall itself. Integrating with and adding to a luxurious interior design, the wallpaper OLED is an effective method for delivering advertisements and information.
