Science and Technology Daily reports on 5th February that the world’s largest ground screen lighted up in the opening ceremony of Beijing 2022 Winter Olympic Games. 

At the National Stadium, this 11,000-square-meter ground screen, together with a 1,200-square-meter vertical screen depicting icefall, a 600-square-meter one shaped like one side of an ice cube, plus 1,000-square-meter screens over the stands compose the largest LED 3D stage in the world, as introduced by Wang Dingfang, project manager of the Opening Ceremony from Leyard Group, the screen supplier.

One highlight of the Opening Ceremony is to empower art with technology. For the first time, 16K HD displays replaced traditional projection on the supersized ground LED screen. Wang Zhiou, Visual Effects Supervisor of the Opening Ceremony said, “Ultra HD images are displayed on a 14,000-resolution giant LED screen covering over 10,000 square meters. This is a massive digital technology project with unprecedented challenges in presenting definition and details of images.” Wang Dingfang said that the entire LED ground screen displayed four 8K videos, the ‘icefall’ screen two, and the ‘ice cube’ screen one. And a control system ensured synchro errors of no more than 2 frames across multiple displays.
