Framing the experience: in-window displays that make an impact

A French leader in Digital Out of Home (DOOH) media, set out to redefine retail advertising by transforming storefronts into digital communication platforms. With a strong presence in urban retail zones, the group needed a solution that combined technical performance, visual clarity, and design harmony—capable of operating flawlessly in sunlight-exposed, space-constrained, and aesthetically demanding environments. The goal was to create a scalable network of digital screens that could deliver brand messages effectively in high-traffic urban areas while remaining non-intrusive inside store interiors.

GDS responded to that vision by designing the 46” and 55” LUMEN, a modular custom high-brightness display solution tailored specifically for in-window retail installations.

Key challenges such as glass reflections, direct sunlight, thermal stress, and noise levels in indoor spaces were overcome through a combination of smart engineering and display innovation. One critical breakthrough was the use of a display structure seamlessly fused to the storefront glass, eliminating optical interference while optimizing visual impact.

Additionally, the LUMEN display solutions were equipped with remote diagnostics and a modular maintenance system, ensuring quick servicing with minimal disruption to store operations.
