Glasses-free 3D Solution
The LED display naked-eye 3D solution is a technical scheme that allows viewers to experience stereoscopic vision on an LED screen without wearing glasses through special hardware design and content production. It is suitable for outdoor advertising, commercial displays, cultural and tourism landmarks, and other scenarios. The core features are as follows:
1. Core Technical Logic
Based on the principle of binocular parallax of the human eye, through hardware optimization of the LED screen and customized content, different perspective images are delivered to the left and right eyes, which the brain fuses to produce a sense of depth. Compared to traditional displays, the key is to precisely control the light projection angle through technical means to achieve "left and right eye image separation."
2. Mainstream Implementation Methods
Cylindrical Lens Technology
A micro-cylindrical lens array is installed on the surface of the LED screen. Each lens refracts pixel light from different perspectives to the corresponding positions of the left and right eyes, achieving parallax separation. Suitable for large screens, with low brightness loss (about 10%-20%) and a wide viewing angle.
Multi-Screen Linkage Design
Using L-shaped, curved, or multi-sided spliced LED screens, the spatial extension of cross-screen content (such as virtual objects "passing through" screen boundaries) enhances the sense of depth. This method requires no complex optical accessories, has lower cost, and is suitable for creating immersive scenes.
Customized Content Driven
Combining the physical characteristics of the screen (size, curvature) to produce exclusive 3D content, using effects like "coming out of the screen" or "going into the screen" (e.g., objects "popping out" or "immersing" into the background) to strengthen the stereoscopic illusion. Content must match the screen's physical parameters to avoid distortion.
3. Hardware and Performance Requirements
- High-spec LED panels: require high refresh rates (≥3840Hz) and high grayscale (above 16bit) to ensure dynamic images have no trailing and dark details are clear.
- Precise calibration system: optical calibration technology ensures no ghosting between left and right eye images, with edge alignment error ≤0.1mm.
- Environmental adaptability: outdoor screens must have high protection (IP65/IP68), anti-light interference (brightness ≥8000 nits), and be suitable for strong light, rain, snow, and other environments.
4. Core Advantages
- Strong visual impact: large-size LED screens combined with 3D effects create a strong "eye-catching" effect, suitable for high-traffic areas to enhance brand exposure.
- No equipment threshold: viewers do not need to wear glasses and can watch anytime, especially suitable for mass dissemination in public places.
- Wide scene adaptability: customizable to any size (from tens to thousands of square meters), suitable for commercial plazas, scenic spots, transportation hubs, and other scenarios.
5. Application Scenarios
- Outdoor Advertising Large Screens: Such as city landmark LED screens, showcasing brand image or product features through 3D effects.
- Cultural and Tourism Performances: Creating immersive 3D light and shadow shows combined with real scenes to enhance visitor interaction experience.
- Commercial Complexes: Setting up 3D screens in atriums, corridors, and other areas to attract foot traffic and enhance the commercial atmosphere.
