Artistic Space beyond Display LG OLED Signage

Blending in with the space while captivating everyone's mind. LG OLED signage offers flexible design. Beyond its informative features, LG OLED signage delivers unsurpassed advertising effectiveness, redesigning space as a prestige-enhancing landmark with perfect colors and innovative forms.

Expandable Screen Size

The screen size can be as large as users want by tiling up displays horizontally and vertically. This provides viewers with an incredibly immersive viewing experience.

Splendid Design

LG OLED technology doesn't require a backlight unit nor a liquid crystal layer so it offers a flexible design with unbelievably lightweight and slim features.

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.

Variety of Curvature for Landmarks

The EF5K series supports various concave and convex curvature in both portrait and landscape orientations. You can differentiate your space in a variety of ways with beautifully curved displays to keep passengers captivated and immersed.

On-site Customization

The EF5K series enables a completely new approach for innovative and flexible designs. Its optional "Curvature Calibrator(CC)" supports the coordination of displays with various convex and concave curvature, depending on the requirements. This makes it possible to rapidly respond to changes on-site, making it easier to successfully build an eye-catching landmark.

LAN Daisy Chain Management

The LAN daisy chain allows users to control and monitor displays, transmit data and even update firmware all at once, reducing management burden.

Videowall Playlist & Sync Playback

Through its built-in high performance SoC, each display plays its video tile for synchronized content playback.
