What Is Naked-Eye 3D Display?
The effect of a naked-eye 3D advertising display typically consists of two angled or curved screens joined together at their seams. While most naked-eye 3D displays we see are angled or curved, it is also possible to achieve naked-eye 3D effects on flat screens.
Naked-eye 3D advertising displays do not require special glasses and can be viewed directly with the naked eye. Through specialized technology and algorithms that simulate the parallax effect of the human eye, viewers can experience 3D effects without the need for eyewear.
The working principle of naked-eye 3D displays typically involves two main aspects: parallax and viewing angles. Parallax refers to the perception of depth and 3D effects by the human eye through differences between the left and right eyes, while viewing angles refer to the images seen by viewers from different positions and angles. Naked-eye 3D advertising displays achieve stereoscopic effects by displaying slightly different images on the screen, creating a small disparity between what the left and right eyes see, thus producing a 3D effect.

Regarding hardware, compared to traditional products, naked-eye 3D LED advertising displays prioritize high refresh rates, high gray scales, high dynamic contrast, and smooth transitions for curved and corner screens. Additionally, playback servers need to connect to professional graphic workstations and feature multi-card frame synchronization. On the software side, more professional decoders are required, capable of supporting material mapping and calibration functions for irregular display carriers, as well as low-level optimization for high-bitrate stream decoding.
The material requirements for naked-eye 3D rely on the surrounding environment of the LED display screen to achieve the best visual effects. Since the shape of each LED display screen and its surrounding environment differ, each 3D video material and presentation result also differ. When the resolution of the content reaches 8K or higher, the rendering becomes clearer, with more details. At the same time, the rendering cost and production time increase with higher resolution requirements.
3D video production in the film and television industry demands the highest level of precision in the previous level. It involves precise models, parameter materials, scale textures, and realistic lighting and shadow effects to achieve visual realism. Different levels have varying degrees of precision, with higher levels featuring more details, richer visual effects, finer animations, more comprehensive levels, more realistic lighting and shadow effects, more extensive stereoscopic movement, richer camera language, and greater demands on production time. For large resolution displays, there are specific requirements for material encoding and packaging formats, generally recommending H.264/H.265/HAP encoding and MP4 format. However, materials are large, with high bit rates, and require a professional decoding platform to ensure smooth and stable playback.
In the production of naked-eye 3D video sources, there are five processes, including creative communication (customer collaboration), material acquisition, video production, screen testing, and sample submission. Typically, a 30-second advertisement can be completed in 30 to 60 days. The application of naked-eye 3D full-color LED displays in various scenarios has become increasingly popular, as this technology and artistic form are adopted by more and more commercial projects to enhance the style of business and create new city landmarks that consumers are eager to visit. Rendering atmosphere technology itself is “cold,” and it is only when it is combined with things that people can easily perceive that it becomes easier to reach consumers. Riding the “immersive” trend, innovative content for 3D naked-eye screens is more likely to ferment and gain extensive exposure and attention.
