Clear Channel Outdoor will also showcase its smaller digital smart screens around the Croisette.
The company is also bringing the Playground, its experiential space, to Le Grand Hotel's gardens at ground level.
The digital OOH showcase will feature dynamic activations from partners including: Biborg, Black Swan, Buzz Radar, Haymarket, Quividi and Kirk&Kirk, LivePoster and Diageo, Ogilvy and Samsung, Stink Studios, Twitter and WCRS.
Creative concepts include conditional-triggered content, mobile gamification, user-generated content, AI, hyper-local contextual relevance, as well as data aggregation, integration and visualisation.
Clear Channel is also sponsoring the Outdoor Lions category of the Cannes Lions Awards for the eighth consecutive year. The winning campaigns will be shown on Le Grand Screen as soon as they're announced.
"We have reached a digital tipping point for out-of-home with scaled digital networks across many of the world’s major cities that allow advertisers to engage audiences with data-driven, real-time, contextually relevant messaging," William Eccleshare, chairman and chief executive of Clear Channel International, said. "But we’re only just scratching the surface of what is creatively possible, so we’re working with a range of partners who have crafted bespoke activations for the event and the unique festival audience, to inspire the global advertising industry about the creative possibilities of out of home."
