In Bazhou, China, a city steeped in Song Dynasty legacy, nightfall brings more than lanterns. At the Great Song Nightless City cultural tourism project, visitors now encounter a breathtaking fusion of cutting-edge technology and ancient heritage: a massive outdoor holographic screen, measuring 5.6 meters wide and 1.6 meters tall, formed by 256 IPX6 waterproof 80cm holographic fans arranged in a 32×8 grid. This monumental installation does not just display images—it resurrects five legendary historical figures from Bazhou’s past, reenacts epic battles, and immerses tourists in the city’s thousand-year story through stunning, glasses-free 3D visuals that appear to float in the night air.
This case study explores the design, installation, and spectacular results of one of China’s largest outdoor holographic cultural installations, where AIHOLO technology and custom 3D content combine to create an unforgettable night tourism experience.
The Vision: Bringing Bazhou’s Song Dynasty Heritage to Life
Bazhou holds a distinguished place in Chinese history, especially during the Song Dynasty, when it served as a strategic military and cultural hub. The goal for the Great Song Nightless City project was to move beyond static displays and passive storytelling. The curators wanted a dynamic, immersive experience that would:
- Introduce key historical figures associated with Bazhou in a way that felt immediate and alive.
- Depict pivotal war scenes with cinematic scale and emotional impact.
- Engage a modern audience with technology that feels magical yet culturally respectful.
- Withstand outdoor conditions for year-round operation in a public space.
The Solution: A 32×8 Waterproof Holographic Video Wall
The Core Technology – 256 IPX6 80cm Fans
The chosen solution was a massive array of 256 units of our A80 IPX6 waterproof 80cm holographic fans. Each fan is rated IPX6, meaning it is fully protected against powerful water jets, ensuring reliable outdoor operation in rain, humidity, and temperature fluctuations. Arranged in a 32-column by 8-row configuration, the fans form a seamless 5.6m × 1.6m display canvas—perfect for life-size human figures and dynamic panoramic scenes.
H3: Custom 3D Content – Five Historical Figures & War Epics
Content was as critical as hardware. Our in-house creative team worked closely with historians and the project’s cultural consultants to design authentic, visually stunning 3D animations that bring Bazhou’s story to life. The content features:
- Five Legendary Figures: Generals, scholars, and cultural icons from the Song Dynasty, each rendered in exquisite detail, appear in sequence or interact in dramatic scenes.
- Historic War Tableaux: Large-scale battle sequences unfold across the screen, with cavalry charges, siege engines, and swirling banners that seem to burst from the night.
- Cultural Symbolism: Motifs of peonies, calligraphy, and traditional architecture weave through the narratives, grounding the spectacle in authentic heritage.
Each scene was optimized for the unique properties of holographic display—deep black backgrounds, rich contrast, and motion that leverages the fans’ high refresh rate to maintain fluid, realistic action.
Key Features & Benefits of the Installation
All-Weather Reliability
With IPX6 waterproof fans, the installation operates flawlessly through Bazhou’s humid summers, rainy seasons, and even dusty conditions. The robust aluminum alloy construction ensures long-term durability with minimal maintenance.
Life-Size Historical Presence
The 1.6-meter height is perfect for human-scale figures, allowing historical characters to appear as if they are standing before visitors. This scale creates a powerful sense of presence, making the past feel immediate and tangible.
Seamless Splicing for Cinematic Impact
Despite being composed of 256 individual fans, the seamless splicing technology ensures zero visual gaps or shadows. The result is a single, continuous canvas that can display panoramic battle scenes or full-length portraits without interruption.
H3: 2500+ Nits Day & Night Visibility
Even in the ambient light of the night market or early evening, the 2500+ nits brightness ensures content remains vivid and clear. The display transitions gracefully from twilight to full darkness, maintaining its visual impact throughout operational hours.
H3: Smart Cloud Management
All 256 fans are managed via a centralized cloud platform, allowing the operations team to update content, synchronize playback, and monitor system health remotely. New historical vignettes or seasonal content can be deployed instantly without physical intervention.
