The Cutting-Edge Technologies Behind the Beijing Winter Olympics Opening Ceremony

The opening ceremony of the Beijing Winter Olympics instantly went viral, topping hot lists both domestically and internationally, with many viewers impressed by its striking sense of technology.

Among the most talked‑about elements were the crystal‑clear ice‑ring, a massive LED display weighing three tons, and the snow‑flake torch embedded with over 550,000 LED beads.

Ice‑Snow Five Rings: 3‑Ton LED Irregular Screen

The opening featured a dazzling ice‑snow five‑ring structure that turned out to be a 20‑meter‑long LED screen weighing three tons. To achieve transparency in extreme weather, a 2 mm PC panel with 70% light transmittance was selected. Instead of using two ground cables for lifting, the team opted for a wire‑less suspension system, powered by aerospace‑grade batteries, reducing the weight from 3.5 tons to exactly three tons.

Snow‑Flake Torch: 550,000 LED Beads

Each delegation entered with a snow‑flake guide plate made of LED beads and fine steel wires, achieving high translucency without 3D printing. A five‑path power supply ensured the torch remained lit even if several lines failed. The main torch, 14.89 m in diameter, comprised 96 snow‑flake and six olive‑branch LED double‑sided screens, containing over 550,000 individually controlled LED beads.

The torch’s display relied on synchronous and asynchronous control systems from BOE, delivering millisecond‑level response, high contrast (100 000:1), 3840 Hz refresh rate, and ultra‑high resolution.

AI‑Assisted Real‑Time Motion Capture

The ceremony achieved the world’s first real‑time AI motion capture of over 600 participants using only four cameras. Intel’s 3DAT 3‑D athlete tracking technology handled detection, positioning, and real‑time rendering within 0.1 seconds, with Beijing Film Academy providing the rendering support.

8K Ground Screen: 42,000+ LED Modules

The 8K ground screen, the world’s largest LED floor at 10 552 m², consisted of more than 42 000 modules. Advanced optical calibration algorithms delivered pixel‑level correction, resulting in ultra‑high contrast, refresh rate, and resolution. The screen was engineered to withstand winter conditions, heavy loads, waterproofing, and low‑temperature operation, with each square meter supporting over 500 kg.

Cloud Streaming and AI Services

All content was broadcast globally via Alibaba Cloud in 4K, with key events streamed in 8K, making the Beijing Winter Olympics the first Olympic Games fully streamed in 4K. Baidu’s AI sign‑language anchor provided 24‑hour sign‑language translation for the hearing‑impaired, and intelligent guide robots offered navigation and health reminders throughout the venue.

These technological feats were made possible by the China Aerospace Science and Technology Corporation, which handled the stage, wiring, torch, ice cube, command and control, communication systems, and video rendering infrastructure.
