The interactive LED floor tile screens can chase the movement trajectory of the cast and crew and transmit it to the control system. The interactive sensing device is the key to realizing the interaction between the LED display screen and the actors.
For example, when the actor is skiing, there are signs of snow being pushed away from where the athlete is paddling. During the Dove of Peace show, snowflakes will appear wherever the children walk. The interactive led floor tile screen makes the scene more realistic.
Ice Waterfall 3D LED Display Screen
In recent years, 3D LED screens are very hot. You can see naked-eye 3D LED displays in many shopping malls. With its shocking and realistic picture effects, it has attracted the attention of many people and caused heated discussions on the Internet. As early as 2012, naked-eye 3D technology appeared. However, there are few relevant cases because of immature technology and funding problems. With the maturity of naked-eye 3D technology and the increasing demand for 3D images, 3D LED screens were used in this Winter Olympics. Let the audience feel the current hot technology power.
At the opening ceremony, the billowing river seemed to pour down from the sky. Then the river water gradually pools and freezes slowly, creating a world of ice and snow. The inspiration for this scene comes from a poem by Chinese Tang Dynasty poet Li Bai – “The water of the Yellow River comes from the sky”. This shocking picture seems to make people feel the majesty of the Yellow River.
Such a shocking display effect is inseparable from the high-quality performance of the 3D LED display. This vertical screen is 58 meters high, 20 meters wide, and has a resolution of 2560×7328. When erecting such a large screen on flat ground, the wind speed in the field is a problem. The icefall led display adopts a grille screen with an aluminum bar structure. These LED grille screens are designed with an overall glue filling process, with a protection level of IP65 and strong wind resistance.
IceCube 3D display is full of creativity
Ice Cube is 22 meters long, 7 meters wide, and 10 meters high. As one of the most-watched famous scenes, the Five Rings of Ice and Snow gradually emerged from the Ice Cube. The Ice Cube, the Olympic Rings, and the local stage are all made of LED displays. Through the control system, the latest light and shadow display technology is helpful to create such a dreamy scene.
Parallel Cube is the world’s largest pentahedral naked-eye 3D display device, and it is also the driving device with the highest power throughout the opening ceremony. The LED display unit adopts a carbon-fiber structure design to reduce weight. The weight of a single display cabinet is only 8kg. This design is conducive to the rapid lifting and lowering of the Ice Cube and presents a visual effect.
The appearance of the Olympic rings also made the audience shine. A laser located on Level four of the Grandstand shines on the IceCube and sculpts it. Then the Olympic rings slowly emerged, instantly igniting the enthusiasm of the audience. According to relevant personnel, this engraving vision is present under the combination of laser and IceCube 3D visual effects.
Olympic Rings - Creative LED Display Stunning appearance
The five rings of ice and snow are one of the most crucial props for the opening ceremony of the Winter Olympics to display the Olympic spirit. The crystal-clear five rings of ice and snow break out of the ice, symbolizing that countries in the world have broken down barriers.
The creative LED display constitutes the five rings, among which the soft flexible LED display plays an important role. The five rings are 19 meters long, 8.75 meters high, and only 35mm thick. The whole adopts an aluminum alloy truss structure that is both rigid and lightweight. It only took 43 seconds to rise steadily to an altitude of 13 meters.
The appearance of the 2008 Summer Olympics Fantasy Rings at the closing ceremony also dazzled the audience. The Dream Five Rings are manufactured by Aerospace Science and Technology Group.
