II. Core Features: Technology Empowers an Extraordinary Experience

Seamless Curved Surfaces: A Natural Visual Experience

Using specially designed curved LED modules, precision craftsmanship achieves large, smooth, and seamless stitching. This eliminates the "fragmented" and "pixel staircase" effect often seen with traditional flat stitching on curved surfaces, ensuring a seamless and consistent image. This is a key technological foundation for immersive viewing.

High Adaptability: Stable and reliable operation around the clock.

High Brightness and Ambient Light Resistance: Brightness typically reaches 1500-8000 nits or even higher, ensuring crisp, clear images even under overhead lighting or in well-lit areas of the exhibition hall, unaffected by ambient light interference.

Wide Viewing Angle and Consistency: A unique optical design ensures highly consistent color and brightness across a wide viewing angle below the hemisphere, eliminating issues such as graying and color cast.

Stability and Lifespan: LED display technology is mature and reliable, with a long lifespan (typically over 100,000 hours) and relatively low maintenance costs, meeting the long-term, high-intensity operation requirements of exhibition halls.

Flexibility and Customization: A Tailor-Made Artwork

Flexible Size: Diameters can range from a few meters to dozens of meters, allowing for customization based on exhibition space size and budget, offering exceptional adaptability.

Diverse Installation Options: Suspended, bracket-supported, and embedded installation options are available to accommodate varying floor heights and building structures.

Convenient Content Playback and Control: Supporting mainstream video signal input, combined with professional playback and integration systems, enables precise delivery, synchronized playback, and interactive control of complex content.

Interactive Integration Potential: From Viewing to Participation

Upgraded Interactive Experience: The dome screen can be integrated with motion capture (Kinect, Leap Motion), touchscreen devices, mobile apps, and spatial positioning systems. This allows viewers' gestures, movements, or position to influence content on the dome in real time, enabling "human-screen interaction" and greatly enhancing engagement and fun. For example, a wave of the hand can dispel overhead clouds or guide the course of a spaceship in the starry sky.
