    • The principle of outdoor advertising naked eye 3D LED display is mainly based on the principle of human binocular parallax, through the left and right eyes to see different image position to produce three-dimensional effects, so that the audience in the case of not wearing 3D glasses, but also can feel the realistic three-dimensional effect. There are a variety of ways to achieve this effect, the more commonly used include the use of high refresh screen with customized naked eye 3D video material, as well as time-sharing multiplexing technology.
    • Technology Principle
     
    • Parallax Barrier Technology: Add a slit grating in front of the screen to block the left and right eyes through opaque stripes, so that the left and right eyes can see different images, thus forming a sense of three-dimensionality.
     
    • Cylindrical Lens Technology : Through the refraction principle of lens, the pixels corresponding to the left and right eyes are projected onto the left and right eyes respectively, realizing image separation, and will not block the light, with higher brightness.
     
    • Directional Light Source Technology: Precisely control the two sets of screens to project images to the left and right eyes respectively, so as to realize stereoscopic effect. Achieve stereoscopic effect
     
    • High refresh screen with customized naked eye 3D video material: By projecting the images seen by the left and right eyes to different areas, the parallax generated by the viewers when viewing at different angles is utilized to create a 3D effect
     
    • Time-sharing multiplexing technology: By quickly switching the images of the left and right eyes so that they are alternately displayed on the screen, creating a three-dimensional visual effect
    • Hardware Configuration 
     
    • High-density LED Module : Adopting a high-density LED module (e.g. P2.5-P1.2 pitch), supporting 440Hz refresh rate and 100% DCI-P3 color gamut coverage
     
    • Curved Screen Body: The curved screen body can realize 90° seamless turning angle to provide better viewing experience
     
    • Eye Tracking Technology: The LCD column lens array is linked with the eye tracking technology to achieve more accurate image separation.
     
    • Ambient Light Sensor: The integrated ambient light sensor automatically adjusts the brightness to adapt to different lighting environments. lighting environments
     
    • Spatial Audio: Combined with 6-speaker spatial audio, it strengthens the immersive experience
     
    • Application Scenarios and Effects
     
    • Commercial Landmarks, Cultural and Tourism Landscapes: Naked Eye 3D Commercial landmarks, cultural and tourism landscapes: naked eye 3D display in these places can provide strong visual impact, quickly capture the attention of the audience, and enhance brand awareness and exposure.
     
    • Interactive experience: Combined with advanced technical means (such as cell phone code scanning, gesture recognition, etc.), the audience can interact with the big screen in real time, increasing the fun and sense of participation in the advertisement.
