[untitled] record the visual shock of the Winter Olympics and the introduction of the display screen

Light up the Winter Olympics night , Liad display flashes at the opening ceremony

The Winter Olympics has recently attracted everyone's attention , Among them, the display of various screens in the opening ceremony is also very shocking , So I checked
Share the information you checked

2 month 4 Day is the fourth day of the Chinese New Year , It is also the day of spring , The Beijing Winter Olympics ushered in spring , It also welcomes athletes and guests from all over the world .4 Friday night 8 when , The first 24 The opening ceremony of the th Winter Olympic Games was held in Beijing “ Bird nest ” The National Stadium .

The opening ceremony of the Winter Olympic Games used the visual feast brought by innovative high and new technology , It shows the charm and romance of Chinese culture . And the world's largest LED Three dimensional stage , Pixels up to 14880x7248, near 8 individual 8K The resolution of the , Perfectly present naked eyes 3D effect .

Stage application LED The total area of the display screen is close to 15000 Square meters , among , Riad offers near 11000 Square meters , Cover the screen in the core area of the stage （7000 Square meters ）、 high 60 The ice waterfall of meters 、 Icecube 、 North and South grandstand screens ; Besides , Liad is also responsible for the design of all the broadcast systems of the whole party 、 Construction and operation guarantee .

In order to present the Winter Olympics digital technology creativity perfectly in front of the world , Cooperate with director Zhang Yimou to tell a good Chinese story , Lyade joins hands with China Aerospace , use 42208 individual 50 Cm square LED The module builds an immersive experience space .

During the opening ceremony ,LED The stage presents from 24 Solar term countdown 、 The water of the Yellow River rises from the sky 、 The ice cube is gradually broken to wonderful pictures such as crystal clear ice and snow rings , adopt LED The display screen is perfectly integrated with light and shadow , Write Chinese style romance .

Let's do another example

And there are naked eyes 3D
Behind the wonderful is the technical support of lyad . For example, the ground screen can show naked eyes 3D effect , There is a black field around the ground screen , Black field is also a screen , When snowflakes fall , It can give people the visual effect of snowflakes . The ground screen is also equipped with an interactive motion capture system , In the nest “ rim of a bowl ” There is a camera installed at , Capture the dynamics of people on the ground screen in real time , Realize dynamic capture , For example, children play with snow on the ground screen , There are snowflakes wherever you go , The dynamic capture system optimizes the scene , It also makes the scene more realistic .
For example , Show China's strength ！

meanwhile , Play the whole ground screen of the system LED Responsible for the display 4 individual 8K Play the material , The ice screen is responsible for displaying 2 individual 8K Play the material , Ice cube is responsible for displaying 1 individual 8K Play the material , Then cooperate with the broadcast control system to realize the synchronization of video output of multiple players , The error does not exceed 2 frame .

It is worth mentioning that , Olympic rings “ carving ” Also by LED The screen is finished . Olympic rings “ carving ” It's in the laser and ice cube 3D Produced by the combination of visual effects . The square length of the ice 22 rice 、 wide 7 rice 、 high 10 rice , By LED The screen is composed of . When the five rings appear , stand 4 The laser of the layer shines on the ice cube , Test the ice cube “ carving ”, As the top cover of the upper part of the ice cube turns down , With the laser “ carving ”, The five rings at the bottom rise slowly , The ice cube is surrounded by LED One side of the screen drops slowly , Play the three-dimensional visual effect of ice slag splashing at the same time , Perfect cooperation in three aspects , The five rings are formed a little “ carving ” The visual effect . Like this

according to the understanding of , Liad made a lot of preparations for the Winter Olympics

The Winter Olympics is a global event , Live performances need to be guaranteed . As the core of vision LED display , Reliability is the top priority .

On the ground of the opening ceremony LED Design and construction of display system , Lyad took the initiative to introduce aerospace quality management methods , Integrate strict standards into every link . After sufficient testing and verification in the early stage , Every piece LED Display module and link cable , Facing winter -20℃ low temperature , As well as the high-intensity rehearsal trampling of actors and the rolling of equipment and machinery , Can stably present super 8K Smooth picture effect of HD video , Overturned the spatial structure of the traditional performance stage , Realize human screen interaction , Create digital multi-dimensional special effects .

For such a super large LED How to make the screen reliable 、 Security 、 Stable power supply is also one of the problems that lyade has to solve . The total power consumption of the three display devices on the opening ceremony stage is very large , Lord , The power load of the standby power supply circuit needs 2600kW, The three devices share 100kW Aviation box distribution cabinet 52 platform ,20kW Power distributor 534 platform , All kinds of wires and cables 198000 rice . Riad design team is LED Dual power supply and dual power mode is adopted in the design of power distribution system of display screen .

We also found the comments of relevant personnel of lyad , I feel very good
According to Li Jun, chairman of lyade Group , The opening ceremony of the Winter Olympics used system four backup and pixel four backup for the first time , Make sure it's safe . System four backup refers to that each equipment of the system is designed as a quick disassembly structure and plug-in mode , In addition to providing necessary spare parts for the system , For quick replacement of outer ,LED The control equipment of the display system also adopts the dual machine full redundant waste heat backup mode , Ensure that during the system operation , Once the main equipment fails , Backup devices can be switched online automatically or manually immediately , To comprehensively ensure the stable operation of the system 、 No downtime . Pixel four backup means that each display pixel is backed up , One display pixel is used 4 star 3 Unity SMD Lights back up with each other , Will four LED Use as a pixel , That is to say, every pixel has four LED Back up at the same time , Any one of them LED A little bad , Will not affect the normal display of individual pixels , There is something wrong with any set of data control chips , This group LED The pixels of the area will not be all black , Each pixel has 2 individual LED Normal display .

Beijing hosted the Summer Olympics and Winter Olympics “ The city of double Olympics ”. and 2008 In, liad participated in creating the dream five rings of the opening ceremony of the Beijing Olympic Games 、 Giant LED Ground screen scroll . stay 2022 The 2008 Winter Olympic Games left another heavy mark . therefore , Riad is worthy of the name “ An enterprise of double Olympics ”.

All in all , This visual shock shows the strength of Riad , Looking up this information, I also got a lot of hardware knowledge ！
