With the arrival of the Spring Festival, the CCTV Spring Festival Gala has once again become the focus of hundreds of millions of viewers. Behind this grand event, there is a company that has quietly accompanied everyone for 26 years — that is Dafeng. Dafeng is not only the technical supporter behind the Spring Festival Gala stage but also a leader in creativity and technology across the entire culture, sports, and tourism industries. Since its first cooperation with the CCTV Spring Festival Gala in 1998, Dafeng, relying on its profound technical accumulation and forward-looking innovative concepts, has brought revolutionary changes to stage art. Under Dafeng's guidance, stage design is no longer limited to traditional sets and props but integrates advanced technological elements. Dafeng's pioneering 'dancing stage' has not only amazed audiences but also brought unprecedented dynamism and three-dimensionality to stage performances. This innovative design was quickly emulated by other performances and stage designs, becoming a new trend in stage technology. Each of Dafeng's innovations has set new benchmarks for the entire industry. We continuously challenge the limits of technology, applying the latest scientific and technological achievements to stage design. In 2012, Dafeng's pioneering 'dancing stage' made 304 lifting platforms move synchronously like elves; in 2017, the perfect interaction between 41 sets of circular platform equipment and lifting platform modules once again pushed the limits of stage performance; in 2019, the perfect integration of 98 sets of 'ice screens' with the stage made the audience feel as if they were in a magical world of ice and snow… Time flies, and in the blink of an eye, it is 2024.

With the arrival of the Spring Festival, the CCTV Spring Festival Gala has once again become the focus of hundreds of millions of viewers. Behind this grand feast, there is a company that has quietly accompanied everyone for 26 years—and that is Dafeng.
Dafeng is not only the technical supporter behind the Gala stage but also a leader in creativity and technology across the entire culture, sports, and tourism industries. Since its first collaboration with the CCTV Spring Festival Gala in 1998, Dafeng has brought revolutionary changes to stage arts through its deep technical expertise and forward-looking innovative ideas.
Under Dafeng's leadership, stage design is no longer limited to traditional sets and props but incorporates advanced technological elements. Dafeng's pioneering "dancing stage" not only impresses the audience but also brings unprecedented dynamism and three-dimensionality to stage performances. This innovative design was quickly imitated by other performances and stage designs, becoming a new trend in stage technology.
Every innovation from Dafeng sets a new benchmark for the entire industry. We constantly push the limits of technology, applying the latest technological achievements to stage design. In 2012, Dafeng's pioneering "dancing stage" made 304 lift platforms move in sync like spirits; In 2017, the perfect interaction between 41 sets of ring platform equipment and lift platform modules once again pushed the limits of stage performance; In 2019, the perfect combination of 98 sets of "ice screens" and the stage made the audience feel as if they were immersed in a magical world of Frozen......
Time flies, and in the blink of an eye, 2024 has arrived. This year, the stage design of the CCTV Spring Festival Gala once again led the trend, innovatively introducing the VP film production model and creating an XR+VP virtual-real integrated ultra-high-definition production system, using a "scenic screen sound and light" collaborative mode to create a dazzling effect. Dafeng's newly created large-scale intelligent panning and rotating screen injected unprecedented technological highlights into this year's Gala. Hundreds of LED screens and over a thousand stage fixtures were all integrated into Dafeng's intelligent panning and rotating screens, which, through precise algorithms and ingenious mechanical design, enabled the stage scenes to change instantly. This design not only enriched the stage's layers and dynamic sense but also brought the audience an unprecedented visual feast.
This year's Gala added ten sets of large intelligent panning and rotating screens, each set of rectangular structures, measuring 12 meters high, 3 meters wide, and 0.75 meters thick, with each screen weighing 5 tons. There are two screen designs: one is double-sided, with LED screens installed on both sides and lights on the sides; the other is an LED screen on one side, with lights on the other side and lights on both sides. Both screens use the same panning and rotation structures. Because the screen height reaches 12 meters and the effective spacing between devices is less than 10cm, shaking may cause collisions between devices and damage the LED screens. The equipment uses dual-track support, with the distance between the tracks maximized to maintain stable movement. The rotary drive uses harmonic shock absorbers, which feature zero tooth side backlash. Once the motor brakes, the entire LED screen maintains a zero-gap stable state, ensuring the rotation angle of the rotating screen。
The intelligent panning rotating screen uses the TUV-certified DAFENG STACON system, ensuring safe operation of the equipment. High-precision encoders and OBB2D collision detection algorithms are embedded in the application to detect collisions between rotating screens and between rotating screens and lift platforms, enhancing equipment safety and stability.
The intelligent panning rotating screen also applies digital twin technology. This technology improves the design, operation, and maintenance efficiency of core units, enhancing safety and innovation. Through virtual design and simulation, engineers can create high-precision 1:1 virtual models to simulate and test mechanical system operation, saving time and resources and improving performance safety. The integration of digital twin technology with automation systems makes mechanical control systems smarter and achieves more complex stage effects. At the same time, to increase system reliability, the CCTV Spring Festival Gala stage system also adopts redundant control systems from primary and backup control systems, which are independent yet compatible with each other, enabling fast and automatic switching.
The DAFENG STACON control system integrates unique algorithms and high-speed data processing technology, capable of responding to stage performance needs in real time, not only enabling intelligent panning and rotating screens for precise multi-angle and multi-dimensional flipping. Combined with the 158 "dancing stages" in the audience, it ensures every program is presented in the most perfect form, providing the audience with an immersive technological experience.
The stage moves exquisitely, combined with intelligent panning and rotating screens, evoking the spirit and spirit of the Chinese people, showcasing their history and hopes. Dynamic effects make every element on stage full of vitality. Moreover, the flexibility and malleability of LED screens offer endless possibilities for stage design, presenting ever-changing visual scenes.
Behind this dreamlike stage lies the continuous accumulation and breakthroughs of Dafeng's innovative technology, and the countless days and nights of hard work by its scientific personnel. They strive for perfection, solely in pursuit of ultimate perfection. This persistent pursuit and selfless dedication allow us to appreciate the endless charm brought by the perfect fusion of creativity and technology.
It is worth mentioning that Dafeng's exploration and application in the technology field are not limited to the CCTV Spring Festival Gala; it actively promotes deep integration and innovative development across culture, sports, tourism, and other broad fields, presenting audiences with richer and more colorful experiences.
Dafeng's mission is "Creativity leads, technology empowers to build a happiness industry in culture, sports, and tourism." In the future, Dafeng will continue to work closely with the CCTV Spring Festival Gala, bringing more excitement and emotion to audiences worldwide, and together composing a new chapter in Chinese culture!
