Coex Seoul's Landmark LED Facade Gets 12K Upgrade from Unilumin
2026-11-12 · via invidis
One of the best-known digital out-of-home landmarks in Seoul has a new display behind its famous curved facade. Kinoton has completed the replacement of the original Samsung LED system at Coex K-Pop Square in Gangnam with a 1,616-square-metre Unilumin Usurface III 6 Pro installation for operator CJ CGV, according to a report from Pro-AVL Asia.
The new screen measures 81.4 by 20.1 metres and runs at a resolution of 12,060 x 3,015 pixels, up from the original 2018 installation's 10mm pixel pitch to 6.67mm. Unilumin and CJ CGV say brightness now reaches 12,000 nits, with a 15,360Hz refresh rate intended to keep high-resolution video content smooth. CJ CGV says the new system cuts maximum power consumption by around 9 percent compared with the display it replaced.
For an industry still dealing with rising energy costs on large-format outdoor LED, that power figure is one of the more relevant numbers here, even if the announcement does not say what the absolute wattage draw is before or after.
What the upgrade preserves
Coex's screen is not just an advertising board. It became internationally known for anamorphic content such as Dstrict's Wave installation, which relies on the facade's curved geometry to create a 3D illusion. The replacement project kept that curve, with a 2.29-metre radius section built into the new installation across 2,156 LED cabinets, so the site can keep running the same style of content that built its reputation.
Current programming includes an adaptation of artist John Gerrard's Western Flag, continuing the venue's mix of commercial digital-out-of-home advertising and public digital art.
Infrastructure and uptime
According to a project report from Analog Way, the processing chain includes two Aquilon C+ processors running in primary and backup configuration, alongside NovaStar H15 Enhanced, VX600 and MX6000 Pro units. Kinoton used Analog Way's Web RCS Emulator to configure and test the system remotely, which the companies say cut on-site setup time by more than half.
That remote-configuration detail matters for a site that reportedly operates 18 hours a day year-round. Any landmark display with that kind of duty cycle has little tolerance for extended downtime during a changeover, and minimising on-site commissioning time is as much a logistics story as a technology one.
The project itself covered removal of the old display, structural work, installation and full system integration. The announcement does not give a project cost or timeline for the works.

Kinoton has replaced the giant curved LED display at Seoul's Coex complex with a 1,616-square-metre Unilumin system, delivering higher resolution, increased brightness and improved energy efficiency.
One of Seoul’s most recognizable digital out-of-home landmarks has received a major technology upgrade, with a new 12K Unilumin LED display replacing the original Samsung installation at Coex K-Pop Square in the Gangnam district.
As reported by Pro-AVL Asia , South Korean integrator Kinoton completed the replacement project for CJ CGV, installing a 1,616-square-meter Unilumin Usurface III 6 Pro display across the building’s curved exterior facade.
The new screen measures 81.4 meters wide and 20.1 meters high (267 by 66 feet), with a resolution of 12,060 × 3,015 pixels.
The replacement display features a 6.67mm pixel pitch, compared with 10mm on the previous installation. Brightness has increased to 12,000 nits, while a 15,360Hz refresh rate supports smooth playback of high-resolution content.
According to CJ CGV, the upgraded system also reduces maximum power consumption by approximately 9% compared with its predecessor.
The installation comprises 2,156 LED cabinets, including a curved section engineered to a 2.29-meter (7.5-foot) radius. The configuration preserves the 3D effect technology that has made the location internationally recognized for anamorphic advertising and digital art.
As detailed in an Analog Way project report , the processing infrastructure includes two Aquilon C+ processors in primary and backup configurations, alongside NovaStar H15 Enhanced, VX600 and MX6000 Pro equipment.
Reliability was a key consideration because the display operates 18 hours daily throughout the year. Kinoton also used Analog Way’s Web RCS Emulator to configure and test the system remotely, reducing on-site setup time by more than 50%.
The project involved removing the previous display, structural design, installation and system integration.
Originally installed in 2018, the Coex display became internationally known for large-scale anamorphic content, including the famous Wave digital art installation, created by Dstrict.
The upgraded screen continues to combine commercial advertising with public digital art. Recent programming includes Western Flag (2017) for Seoul, an adaptation of Irish artist John Gerrard’s work depicting a plume of black smoke rising from an oil field.
The installation demonstrates how established DooH landmarks can be modernized with higher-resolution LED technology while retaining the distinctive visual effects that made them popular.
