On the bank of Hangzhou's West Lake, a scenic spot full of poetry and romance, the design of MNLED" 4D floating screen" is like a creative feast intertwined with technology and aesthetics, attracting countless attention. The comparative consideration of different design plans is a key prelude to creating this visual spectacle, which contains many exquisite details worthy of in-depth exploration.
1. Modeling flexibility: diversified presentation of the beauty of agility
As"" one of the core elements of MNLED 4D floating screen design, modeling flexibility directly determines its visual charm and adaptability in the unique landscape environment along the West Lake.
第一种方案虽具备一定的可动性，但开启扇最大移动距离相对有限，仅为 2.4m，在塑造动态造型时的变化幅度稍显不足。The size of the movable panels are 4x2.4m and 2.5x2.4m respectively, and the number of movable panels reaches 57, which makes the overall structure a little complicated when moving, like a slightly messy dance, making it difficult to form a simple and highly impactful visual focus. In addition, both the upper and lower plates require sliding devices, which not only increases the complexity of the equipment layout, but also puts forward strict requirements for the accurate determination of the equipment position. It is like walking on a narrow steel wire, and there is no room for any mistakes.
反观第二种方案，开启扇最大移动距离提升至 3.3m，为造型的动态变化提供了更广阔的空间，仿佛赋予了屏幕更舒展的肢体语言。The size of the movable panel is 4.9x2.4m, and the number of movable panels is reduced to 60, which not only ensures the display area, but also makes the movement rhythm more concise and lively. Its unique advantage is that it can combine multiple combinations of upper and lower opening plates, just like a smart magician, creating a dynamic and smart facade shape. The fully open state of the upper movable plate can form a high-level complete large screen, like a flag flying in the sky, highlighting the entire screen effect and instantly attracting the attention of tourists from afar; Although the junction between the lower sliding plate and the fixed LEDs on the bottom needs to be handled with care, once the seamless LED effect is successfully achieved, it will be like a perfect ribbon that naturally connects the entire screen with the ground. The fixed LED screens at the bottom and lower parts form a U-shaped fixed screen. Further consideration is given to the integrated seamless design, making the entire screen and the surrounding environment of the West Lake more harmoniously integrated, like a flower of technology that naturally grows out of the lakes and mountains.
2. The best line of sight distance: accurate positioning of visual experience
The best line-of-sight distance is related to whether the audience can get the most shocking and comfortable viewing experience while walking and resting by the West Lake.
The optimal line-of-sight distance for the first option is set to 28m. At this distance, the audience's perception of screen details and overall dynamic effects is relatively balanced. However, due to the limitation of its modeling flexibility, it is difficult to form a strong visual impact when viewing from a distance. The impact is like appreciating a painting through a layer of gauze, and I always feel that it lacks the power to shock the soul.
The best line-of-sight distance for the second solution is 14m. The relatively closer distance allows the audience to more clearly appreciate the high-resolution picture and delicate dynamic changes of the screen, especially when appreciating the complete large screen at the top, such as close listening to an exciting symphony at a distance, every note (pixel) can hit the soul directly. At the same time, combined with its more creative design, when viewing it up close, the audience can more deeply feel the interaction and blending between the screen and itself, as if they are in the world of virtual and reality intertwined created by the screen.
3. Difficulties in sliding mechanisms: Deep challenges in mechanical intelligence
The sliding mechanism is the key joint for the MNLED" 4D floating screen" to achieve dynamic effects"", and its design difficulty directly affects the reliability and stability of the screen.
The first solution requires sliding devices for the upper and lower plates and the large number of movable panels, which makes the layout and collaborative work of mechanical devices face huge challenges. Just like conducting a huge and complex symphony performance, each instrument (sliding device) requires precise rhythm and harmonious coordination. Any carelessness may lead to chaos and failure in the entire performance (screen movement). Determining the location of equipment requires even more caution. It is like looking for an exit in a maze. A wrong choice may trigger a chain reaction that affects the normal operation of the entire system.
The second option can form a high-level complete large screen when the upper movable plate is fully opened, but the upper sliding device also needs to withstand large load and motion accuracy requirements. The treatment of the lower sliding plate and the bottom fixed LED closing area is not only an aesthetic consideration, but also a severe test for the mechanical structure design. It is necessary to ensure the stability and sealing of the neck during frequent sliding processes, like building a strong and waterproof ship that can still be safe in rough seas (frequent screen use).
4. Difficulty in closing the bottom LED screen: the ultimate test of aesthetics and craftsmanship
The difficulty of closing the bottom LED screen is directly related to"" the natural smoothness and visual integrity of the entire MNLED 4D floating screen and the ground.
The first solution faces interference caused by the sliding devices of the upper and lower plates in closing the bottom LED screen. It is like when weaving a complex fishing net, you must also take into account the neatness and beauty of the edges. The difficulty is imaginable. To achieve a seamless LED effect, many technical and technological problems need to be overcome. A slight flaw may destroy the visual beauty of the entire screen. Like a slight flaw on white jade, it is particularly dazzling in the West Lake, an environment that pursues extreme beauty.
In the second option, the LED screens are fixed at the bottom and lower parts to form a U-shaped fixed screen. Although it has unique creativity and potential in integrated seamless design, it also needs to be carefully crafted. It is necessary to deal with issues such as the edge transition of the U-shaped structure, the fit with the ground, and the uniformity of light between different plates. It is like creating an exquisite jade piece, from material selection (LED screen materials) to carving (closing process). We need to strive for excellence in every aspect so that this piece of scientific and technological art can shine the brightest light on the edge of the West Lake.
综上所述，杭州西湖边 MNLED" 4D 悬浮屏" 的两种设计方案在造型灵活性、最佳视线距离、滑动机械装置难点以及底部 LED 屏幕收口难度等方面均呈现出各自的特点与挑战。The decision of the final plan requires a fine trade-off and clever integration of various factors such as pursuing visual shock effects, ensuring mechanical reliability, meeting aesthetic process requirements, and adapting to the specific environment of the West Lake, so as to create this unique technological landscape along the West Lake. The visual spectacle makes it a new business card for Hangzhou's urban science and technology and cultural charm. It shines through the long river of years, attracting tourists from all over the world to stop and admire and linger.
