How Does Naked Eye 3D LED Display Develop into a Trend？
In May 2020, a huge “water tank” appeared on the streets of South Korea. By simulating the turbulent state of the waves in the building, it showed amazing effects, instantly became a popular short video platform, and successfully attracted the attention of many tourists.
This huge “fish tank” is actually a giant LED curved screen 20m high and 80m long, located on the roof of SMTOWN, Seoul, South Korea. This cool idea has become the first choice for outdoor LED display modeling design.
From the 3D wave screen in South Korea’s SM building to the popularity of naked eye 3D LED curved screen in Chengdu, Chongqing, Guangzhou and other places in China, these realistic display effects refresh the public’s understanding of naked eye 3D display technology. Naked Eye 3D LED display around the world have been added to the online red card package of tourists, becoming a classic case of outdoor advertising. “Naked eye 3D LED screens” have quickly become a hot word in the industry.
At present, the naked eye 3D LED display screen is not only limited to advertising communication. Its artistic shape and cool content design create a lot of city landmarks, which represent a city’s heritage and style. With the help of short video platforms, its communication efficiency is far higher than that of traditional LED displays.
The naked eye 3D LED display screen is usually built at the corner of the building. Its ideal form is a right angle screen, which presents a naked eye 3D effect combining virtual and real through content creation. Of course, arc-shaped screens, angled screens from other angles, and even flat screens can present naked eye 3D effects through content design, but the immersion effect is slightly different due to different screen sizes. All immersive 3D content design is based on the viewpoint of the largest audience.
Design Principles of Naked Eye 3D LED Display
- Broad Audience Principle
The large naked eye 3D LED display screen is usually designed as an L-shaped right angle screen. The L-shaped screen can more show the spatial stereoscopic sense of the physical shape. The screen axis is directly opposite to the entrance and exit of the commercial street or the square with large traffic. People coming out of the commercial street can easily notice it and see two sides.
Secondly, it is highly appropriate and easy to enter the line of sight of pedestrians. The screen size design pays attention to immersion, making it the protagonist of the whole building; Finally, pay attention to the technical details to make it more pure. Different from the traditional LED screen in the commercial street, it looks more like a 3D object, breaks through the barrier of the two-dimensional world, and is the transition between the two-dimensional world and the 3D world.
- Follow the Resolution Point-to-Point Principle
In terms of screen size design, the current standard resolution in the field of video production is usually 2K or 4K. Because there is only one ideal camera position (viewpoint) for naked eye 3D LED display screen, that is to say, the user’s eyes can actually see only one perspective image, so it is necessary to ensure that the resolution of the image on one-sided screen is not less than 2K. In order to present rich 3D visual effects.
- Physical Screen Modeling Needs to Present a Sense of Space
The reason why naked eye 3D LED screen can see 3D effects is to use the parallax characteristics of human eyes to establish a hierarchical three-dimensional spatial relationship, design the depth of physical space from the screen modeling, and present a virtual space through video design, which can only be seen but is difficult to touch.
In the 1980s, Jaron canier proposed the concept of “virtual reality”, which means virtual reality. The so-called virtual reality means that the computer generates a real-time dynamic three-dimensional realistic image, which brings realism to the majority of users through interaction with users. This kind of virtual space has rich forms of expression, such as through the mutual proportion of advertising elements, and also through factors such as image materials, which can better express the infinity of space.
In the design process of naked eye 3D advertising, designers will generally adjust the advertising elements, and if the proportion in the three-dimensional space is effectively adjusted, or the spatial arrangement is adjusted, then an infinite three-dimensional space with good stereoscopic effect can be established.
- Immersive Experience Principle
Because the naked eye 3D screen is special, it is not suitable for close viewing. If the screen size is different, the viewing distance will be different. The design of the audience’s viewpoint should follow the axonometric position that can see the full picture of the display screen and be located in most of the audience space of the whole business.
Different from the traditional screen, the naked eye 3D LED display screen is a naked eye 3D effect produced by combining the physical shape of the screen with three-dimensional video rendering.
In order to improve the visibility of naked eye advertising, it is very important to divide the space of visual elements and visual levels in the design process, which can have an important impact on the information transmission of advertising and the visual experience of the audience. In addition, the primary and secondary relationships and hierarchical relationships of elements will have an impact on the transmission of information.
