Additionally, the natural documentary “Postcards from Earth” utilized the Sphere’s immersive narrative style, enhancing the overall immersive experience.
Exterior Sphere Display System
The Sphere’s exterior LED screen spans 54,000 m², exceeding the size of three football fields, making it the largest LED screen globally. Composed of 48 independent LED modules arranged in concentric circles, the screen features 1.2 million pixel units with a 20 cm pitch. Supported by an 86-meter temporary tower and a 154-ton compressed ring, the exterior sphere maintains stability and displays ultra-high brightness of over 4000 nits, ensuring clear visuals even under daylight.
Interior Sphere Display System
Inside, the Sphere boasts a 15,000 m² LED screen with a resolution of 19,000 × 13,500 pixels. LED beads are spaced 9-10 mm apart on a grid, achieving a 25% aperture rate. Supported by a 730-ton arched steel structure, the interior screen offers a panoramic view without obstructive pillars, providing an immersive visual experience from any seating position.
Stage Lighting and Mechanics
Unlike traditional dome cinemas that lack stages and lighting systems, the Sphere integrates these elements to host live performances. For the U2 concert, the stage featured a circular screen and a square screen, meticulously assembled to ensure seamless visual consistency. The stage utilized custom-shaped LED panels and innovative mounting systems, enabling dynamic lighting effects that enhanced the overall immersive experience.
Sound System
Creating a high-quality immersive sound experience in the Sphere’s vast spherical space involved innovative solutions. The Sphere Immersive Sound system employs beamforming and wave field synthesis technologies, utilizing 1,600 fixed and 300 movable rectangular speaker arrays. These 167,000 speakers ensure precise sound coverage, allowing each audience member to experience clear, full-frequency sound without interference or echo issues common in large dome structures.
Motion Seats
Enhancing the audiovisual immersion, the Sphere integrates over 10,000 motion seats equipped with tactile feedback systems and sub-low-frequency transducers. These seats vibrate and move in sync with the performance, providing physical sensations like vibration, wind, temperature changes, and even scents, offering a comprehensive multi-sensory experience.
Immersive Content
The Sphere’s high-resolution 16K LED screens necessitate advanced content production. The Sphere Studios developed the “Big Sky” camera system with a 316-million-pixel HDR sensor, enabling single-camera 16K captures and eliminating the need for multiple cameras and complex stitching processes.
