It is not only large in area, but also world-class in technology! BOE adopts multiple picture fusion technologies with 8K + resolution. The super large-scale optical correction algorithm can perform pixel level optical correction for each display picture, showing 100000:1 ultra-high contrast, 3840hz ultra-high refresh rate, and 29900x15096 ultra-high resolution ultra-high definition gorgeous pictures < p > equipped with the super large-scale display module control and synchronization system independently developed by BOE, it can also capture the moving track of actors in real time, realize the seamless interaction between the picture and actors, and perfectly present the dreamy and realistic beauty of science and technology to the world < p > @ China Aerospace Science and Technology Group: the stage system is constructed by 15 Institute of AVIC I. The construction area of the whole ground stage system is about 21000 square meters, and there is a huge lifting platform in the center of the stage. In the whole opening ceremony, many creative performances such as snowflake platform and torch were completed on this central lifting platform < p > the ground screen is constructed by 12 Institute of avic-1. The ground display screen with an area of more than 10100 square meters, composed of more than 40000 screens, deserves to be the most in the world. Behind the display screen, tens of thousands of signals are transmitted rapidly in complex lines. 12 Avenue companies are responsible for the construction of this broadcast control system. Relying on the avenue company's own industrial Internet platform - Long March cloud platform, tens of thousands of screens are connected, and their working conditions of temperature, humidity and voltage are monitored at all times < p > flags flutter on the towering flagpoles on both sides of the stage. The design of these flagpoles is also completed by astronauts. The flagpole is equipped with rotation function, which can better adapt to the change of wind direction of the bird's nest, so that the flag can flutter in the wind at any time < p > [400t ice cube] < / P > < p > @ China Aerospace Science and Technology Group: the ice cube, with a weight of 400t and a lifting weight of 180t, is the maximum power driving equipment for the whole opening and closing ceremony. Before the ice cube rose, it was "hidden" in a huge bunker with a depth of 10 meters. Institute 15 of our first institute adopts a multi-level folding structure, so that the maximum lifting speed of the ice cube can reach 0.28 meters per second, completing the whole lifting process. The shortest time is 43 seconds, and the operation error is only plus or minus 1 mm. After the ice cube rises, the Olympic rings slowly appear. The hoisting of the five rings is a difficult point and has strict weight restrictions. Therefore, although it has a large volume, its thickness is actually very thin. At the moment when the fifth ring broke through the ice, the 15 project teams of the first Institute did many simulations and field tests, and finally completed the perfect appearance of the fifth ring < p > [torch] < / P > < p > @ China Aerospace Science and Technology Group: the main torch combustion system developed by 11 institutes (Beijing) and 101 Institutes of AVIC 6 is the core part of the main torch. The team has made many innovations according to the requirements of the organizing committee. For example, according to the requirements of flame color visualization, a micro developer formula is implanted in the hydrogen flame area; Linear multipoint coupled gas distribution technology is adopted to realize the modeling of "flying" and elegant flame; In the aspect of "snowflake" special-shaped screen, the color LED direct display screen scheme is adopted, and the light emitting surface is designed according to the dance beauty shape, taking into account the beautiful hollowing out, so as to realize the colorful change of lighting patterns. In addition, 508 Institute of the Fifth Academy of engineering has built a test environment simulating the main torch by using the spacecraft recovery and landing test site, which has made an important contribution to ensuring the reliability and smoothness of all links of the ignition ceremony < p > < p > @ BOE BOE: at the end of the opening ceremony, the appearance of the giant "snowflake" shaped main torch platform surprised the whole audience again. This unprecedented snowflake form of the main torch platform in history, both the overall hardware support and software system are independently developed and designed by BOE < p > in order to realize the creative idea that the director group's torch platform should shine like a diamond, BOE's core R & D team has developed the single pixel controllable special-shaped display product with the narrowest luminous surface in the industry through more than 500 design drawings and nearly 10 rounds of sample preparation, and adopted BOE aiot technology system and self-developed synchronous / asynchronous compatible messaging system, Synchronous centralized control ensures that 102 double-sided screens achieve millisecond response, so that the giant snowflake screen radiates from the center to the surrounding, shining a wave like layer by layer bright light
