A New Level of See-through View
LG Transparent OLED signage illuminates spaces that once were hidden away behind the display, completely harmonizing with its surroundings.
FULL OF LIFE
Unrivaled Picture Quality
LG’s OLED technology, featuring self-lighting pixels, maintains accurate and vivid colors even when the display becomes transparent. It brings content to life, making it difficult for people to separate content from the real objects placed behind the screen.
SPATIAL HARMONY
High Transparency
Thanks to its high transparency (38%), much higher than conventional LCD transparent displays, LG Transparent OLED signage blends into its surroundings seamlessly and naturally. The display’s see-through view turns places where it is installed into open and interactive spaces.
SPATIAL HARMONY
Customizable and Expandable Design
LG Transparent OLED signage is designed as a semi-assembled display, meaning you can install it in various ways to fit into existing structures and spaces. There is no limit to the applications of Transparent OLED signage, and it can complement any venue in which it is installed.* Installation accessories are not supplied by LG.

SEE THROUGH
Effective Information Delivery
While clearly showing objects behind the screen, LG Transparent OLED signage overlays information right over them so that viewers can easily see both the object and the relevant information without having to change their view.
VISUAL FEAST
AR Effects in the Dark
Using LG transparent OLED signage, you can surprise viewers with AR effects in the dark. The content displayed seems life-like, adding another “wow” factor to the viewing experience.
PRODUCT DURABILITY
Robust Design for Safety
The tempered front glass protects the screen from external impact, and its verified safety design means it is reliable enough to endure shock and vibration caused by the surrounding environment, such as moving trains.Tech Spec
