At 8 p.m. on February 4, the opening ceremony of 2022 Winter Olympic Games opened in Beijing’s “bird’s nest” National Stadium. At the same time, Appotronics Corporation Limited(688007) thousands of miles away, used a laser to write on the cloud and hit the “five rings” at the Shenzhen Branch of the opening ceremony of the Winter Olympic Games.
At the scene, four dazzling laser beams soared into the sky. For the first time in the world, laser was used to write the words “one family in the world” on the cloud, and the “five rings” logo was printed on the cloud to cheer for the Winter Olympics.
It is reported that the allusion of “one family in the world” comes from the book of rites · ritual transportation. The world refers to one country, the world and all mankind. One family, one big family. The whole world is home. “One family in the world” aims to convey that people all over the world should uphold the concept of “one family in the world”, open their arms, understand each other, seek common ground while reserving differences, and work together to build a community with a shared future for mankind.
the projection equipment adopts the ALPD laser display technology independently developed by Appotronics Corporation Limited(688007) , which has the characteristics of high brightness, high image quality and high reliability.
According to the on-site technicians, the equipment using this technology can greatly improve the electro-optic conversion efficiency and reduce the heat loss. Combined with the heat dissipation technology of 3dvc, the volume is doubled, which can solve many technical problems, such as low electro-optic conversion efficiency, large calorific value and the need for large heat dissipation devices.
At the same time, according to the requirements of the “book in the cloud” of the project, the ultra far distance projection technology is superimposed synchronously, which breaks through the distance limit of 500 meters of conventional projection technology, realizes the long-distance imaging of up to 3000 meters and up to 100000 lumen brightness, and shows the clear picture visible to the naked eye in the clouds.
According to the data, Appotronics Corporation Limited(688007) is the first batch of listed enterprises on the science and innovation board, the first share of the science and innovation board in Guangdong and the first share of the laser display industry. The company took the lead in inventing ALPD laser display technology in 2007 and realizing technology industrialization in the world. The display scheme covers laser intelligent micro projection, laser display core devices, laser film projection equipment, laser engineering, laser education and so on.
