1, thousands of square meters of LED curtain
The Olympic Games is a large-scale event in the world. The opening ceremony always uses many cutting-edge display technologies. Especially for the Beijing Olympic Games, it can be said that the application of display technology is a lot of effort. Even foreign reporters are amazed at the grand opening ceremony of the Beijing Olympics. I am afraid that latecomers are incomparable. After watching the Rio Olympic Games today, although the funding for the Rio Olympic Games is limited compared to the Beijing Olympics, there is not much shabby for the investment in light source technology. Today, let's take a look at the display technology used by the Olympic Games.
Nearly 5000 square meters of LED resolution 4 major display technology of the Olympic Games
At the time of the Beijing Olympics, the application of LED screens was unprecedented. The opening scroll opens on a huge LED screen. With a screen length of 147 meters, it is a huge platform with the highest technological content. It constitutes the largest stage of the opening ceremony and has 44,000 LEDs on it. The high-tech LED ground has been repeatedly tested to withstand the challenges of actor trampling and flooding. Ground LED display screen total area of ​​4564 square meters, this effect is really no one.

In addition, the opening of the LED five-ring area of ​​nearly 600m2, composed of blue and white LED, nearly 50,000 LED components such a shock display. During the opening ceremony, the Peace Dove program was released. The performers also used LED light sources. The display team used by more than 10,000 people used more than 30,000 LEDs. Only the number of LEDs in these projects has reached more than 100,000, and LED products can be described as brilliant in the Beijing Olympic Games.

At the London Olympics, LED products also appeared. The various torch relay scenes and the LED display on the torch relay body were examples. However, in the Rio Olympic Games, LED products are much less, mainly because the price of LED products is not cheap. Rio’s funding for the Olympic Games is limited.
2, large screen projection fusion
At the Olympic Games, the projector is also an important display product. At the Beijing Olympics. 147 sets of highlighting projectors have created the most exquisite and spectacular visual designs in the history of the opening ceremony of the Olympic Games. The world’s largest screen is 500 meters long and 14 meters high. This huge picture uses occasional full-HD resolution (2048x1080), and each image gets 17,000 ANSI lumens of brightness. To achieve seamless projection, the technicians decided to use 21 channels. Each channel needs to provide images with 10% edge fusion tolerance. The application of this projector has laid a good foundation for the use of projectors in the post-Olympic Games.

At the opening ceremony of the Rio Olympic Games, more than 100 20,000 lumen projectors were installed at the venue, the Maracana Stadium, to assist the opening ceremony. The projector became the protagonist of this Olympics. During the passionate dance of Brazilians, the unique charm of the projector was created to allow the world to see the power of the projector.
The cost advantage of the projector becomes more and more obvious
The advantages of the projector compared to the cost of the LED. In particular, the recent decline in the price of engineering projectors, coupled with the development of laser light sources, compared to the time of 2008, to create a projection of large-scale display program, the cost is much lower. Both the cost of the light source, the cost of the fuser, and the price of the stand-alone projector have now grown considerably and prices have continued to fall. I believe that more projection opportunities later appeared in the opening ceremony of the Olympic Games.
3, the incomparable giant LCD
In the Rio Olympic Games, there are new developments in LCD technology. This Olympic Games has an 8K LCD screen. In the landmark building of the Museum of Tomorrow, Brazil’s Universal TV set up the “Experience Tomorrow TV Evolution in Brazil†exhibition, which uses the only 8K LCD TV in the world to showcase the Olympic style.
8K Panel Appears in Rio Olympic Games
This panel comes from the Chinese panel company BOE (BOE). It has a 98-inch screen size with a resolution of up to 7680 x 4320, which is 4 times the display quality of a 4K (UHD) display, and it is 16 times the current mainstream HD (FHD) resolution. At present, the penetration rate of 4K TVs in China has been getting higher and higher, but 8K products are still very rare. The 8K LCD panels have appeared in this Olympic Games. It is believed that the future will become a new benchmark for resolution development.
The sophistication of the 8K panel is very clear
The 8K panel itself does not have any technical problems. It is a matter of cost to make an 8K panel, and the cost of the 8K panel is not an independent issue. If you want to solve the 8K projection, but you can play the 8K video device, the price will be lower than the panel. It's expensive, so the current 8K pilot is just an attempt.
4, free perspective VR technology
VR virtual display is currently a popular technology and is also reflected in the Olympic Games. There are also VR broadcasts for this Olympic Games. However, due to the current unequal equipment and transmission issues, the number of users who can really receive VR broadcasts is very small. But with the maturity of VR technology in the future, perhaps the combination of VR and the Olympic Games will be even closer.
VR display has a more liberal perspective
Angular freedom is the biggest advantage of VR technology. As long as there are 360-degree camera positions, you can view the stadium from its perspective, not only limited to the auditorium or the viewing angle that the director wants to show you. When we watch the Olympic Games, we can see more details of the game and there are more angles. Not only the game players but also many audiences can be seen. This kind of fresh visual experience is of interest to many people.
There are certain problems with the current shooting and transmission of VR technology
LED large screens, projection displays, liquid crystal displays, and VR displays have all been applied to the Olympic Games. Compared to the past, the Olympic Games could only use fireworks and other mechanical means. It can be said that the Olympic Games has increasingly highlighted the taste of technology. The display industry's rapid development, combined with the practical application of the ability is also growing stronger, I believe that in the future Olympic Games will appear more display black technology.
