The Beijing 2022 presentation during the closing ceremony of the 2018 PyeongChang Winter Olympic Games on Sunday night extended China’s invitation to the world and also displayed some of the country’s top-notch technologies on the global stage.
The 24 screens, known as the “Ice Screens,” showcasing images of China’s achievements in high technology, were designed by YIPLED, a Shenzhen-based LED company that provides smart LED screens featuring see-through glass technology.
“We are currently leading the technology worldwide as we are the only manufacturer that can produce 3-meter-long screens with no beam in the middle,” said Huang Qingsheng, project director with the company.

Actors pushed the screens and positioned them in various formations during the eight-minute presentation on ice.
To keep the actors warm, another high technology — graphene — was used to make special clothes that can provide heat to protect the actors from the cold.
“The actors’ costumes needed to be light so that they could move freely and gracefully, but they also needed to be warm,” according to Li Yueqiu from Grahope New Materials, a graphene corporation in Shenzhen that provided the costumes for the actors.
“We were first required to design costumes that would continue to heat up for 8 minutes in minus 5 degrees Celsius conditions, but later we had to make an adjustment to make the costumes heat up for two hours in a minus-20-degree Celsius environment,” said Li.
