Thousands of red ribbons synthesized with AR
Flying and dancing in the air
Eventually woven into
The Chinese knot, which symbolizes auspicious unity

Welcome to the pine when you come
Fold the willow when you send it
On a 10,522 square meter large ground display
The light and shadow are like real wickers clinging to each other
On the evening of February 20, with the crystal clear "snowflake" image in the center of the bird's nest extinguished layer by layer, the 2022 Beijing Winter Olympic Games, which lasted for 16 days, came to a successful conclusion. Just like the opening ceremony, under the blessing of various "black technologies", the visual feast of the closing ceremony once again swept the screen across the network, which made people marvel!
The largest LED three-dimensional ground screen shows the ultimate beauty of visual effects
The opening and closing ceremonies
It uses the largest screen design in the history of the Olympic Games
This is unprecedented
"Create the most realistic ice effect"
It is the most extreme requirement for the super ground screen
Sha Xiaolan, director of the closing ceremony of the Beijing Winter Olympics, said: "This year's Winter Olympics is mainly to show the spirit of the Chinese, scientific and technological innovation, and there are many breakthroughs in light and shadow interaction and performing arts technology, and for the first time in the history of the Olympic Games, more than 10,000 square meters of LED screens are used. The more than 10,000 square meters of LED screens are developed and designed by Haidian high-tech enterprise Leyard Group.
"After full testing and verification in the early stage, each LED display module and link cable, in the face of the low temperature of minus 20 degrees Celsius in winter, as well as the actor's high-intensity rehearsal stampede and the crushing of equipment machinery, can stably present the smooth picture effect of ultra-8K high-definition video, subvert the spatial structure of the traditional performance stage, realize human-screen interaction, and create digital multi-dimensional space special effects." The relevant person in charge of Leyard Group told reporters.
Improve technical details to ensure the "ultimate" effect
At the closing ceremony, only 10,600 square meters of 8K ultra-high-definition LED floor screens were retained in the Bird's Nest, which echoed with the 1,000-square-meter ultra-high-definition broadcast screens on the north and south sides, and used digital display technology to show "ethereal and romantic".
Tens of thousands of square meters of super large LED screen, how to achieve reliable, safe and stable power supply is also one of the problems to be solved by the technical team.
"We have adopted a dual power supply dual power mode in the design of the power distribution system of the LED display." The relevant person in charge of Leyard said. Dual power, dual power supply, that is, in each LED unit box is equipped with a main and a standby two switching power supplies, the working mode of the two power supplies is a shared current hot standby mode. When the power supply is normal, each power supply carries 50% of the power load, and when one of the power supplies fails, the other power supply can immediately carry 100% of the power load, without switching off delay.
In order to cope with extreme weather, the LED display and its components all meet the IP66 protection standard, even if the water intake of the appliance will not have a harmful effect even when it is subjected to strong water spraying. In addition, the LED ground screen display panel is also equipped with an anti-glare and anti-slip atomization mask to provide a pure video display screen without clutter and interference for video broadcasting.
Perfect fit with Milan for 8 minutes
Two children pushing a giant globe
Roll slowly on the ice
The ice beneath his feet cracked
Illuminated by the snowflake main torch stand
The cracked ice surface shows the theme of the next Winter Olympics in Milan
"Twin cities together, together"
The camera turns
A double dance is staged inside the nest
Two dancers at their feet
Maps of both cities appear at the same time
As the dances merge with each other
You can always trust China
When the director group applies naked-eye 3D technology
Let the 2008 Olympic Games and the current Winter Olympics flame meet in time and space
When the Golden Sail Choir appeared for the second time
The songs of "Me and You" and "Snowflake" are intertwined
Images of snowflakes on the ground converge into five rings and rise slowly
Echo the virtual snowflakes that lift off
Moments of history overlap each other at this moment
Countless memories came to mind
From 2008 to 2022
When audiovisual technology resonates with the Olympic Games again
Countless people have witnessed the rise of China's scientific and technological power
Leyard said it's also a business
The most sincere gift for the "City of The Two Olympics"
Not only from this opening and closing ceremony
More confident cultural expression
It also comes from the underlying technology that supports everything
Artists are able to unleash their creative inspiration
Originated from many companies like Leyard
Use technology to satisfy the whole imagination of art
