ข่าว บริษัท เกี่ยวกับ Dome screen, the ultimate equipment for the ultimate audio-visual experience

Currently, audio, visual, and imaging elements have become crucial components of many theme parks, science museums, and various cultural and tourism projects, significantly enhancing the appeal of each attraction. The dome is undoubtedly the ultimate piece of equipment. Its unique physical form allows for over 70% visual coverage, making it recognized as the most immersive display and experience.

As a core vehicle for immersive experiences in cultural tourism, science, and education, the value of domes goes far beyond the physical property of "70% visual coverage"--it's the result of a deep integration of technological iteration, content innovation, and user needs. We can further explore this topic from four perspectives: technical principles, application scenarios, industry challenges, and future trends.

The immersive quality of domes isn't simply due to their large size; it's a systemic engineering effort involving the coordinated efforts of multiple technologies:

Domes typically utilize a dome-like structure (ranging in diameter from a few to dozens of meters). Positioned at or near the center of the dome, the audience's field of view is completely enclosed by the image, naturally avoiding the border interference of traditional screens. This design conforms to the "field of view" of human vision (the human eye has a horizontal field of view of approximately 160° and a vertical field of view of approximately 130°). The dome's image covers over 90% of the effective field of view, allowing the brain to default to "what you see is reality."

Early domes relied on multiple film projectors spliced together, resulting in blurry images and insufficient brightness. This has now been upgraded to "laser digital fusion technology"--using dozens or even dozens of laser projectors to seamlessly stitch images together into a 360° panorama. Resolutions can reach 8K or even 16K, with brightness and contrast that can adapt to natural daylight conditions (such as in outdoor cultural and tourism projects).

A high-quality dome experience is complemented by "6.1-channel surround sound" (sound direction matches image motion), "dynamic seating" (simulating swooping and pitching), and even "environmental effects" (such as scent, wind, and mist). For example, the Shanghai Planetarium's "dome theater" plays the "Big Bang" scene, and the seats vibrate with the image, accompanied by the booming subwoofer, giving the audience the illusion of being "at the center of the explosion."

Dome screens have long since transcended the limitations of being limited to planetariums and are now permeating a wider range of settings, each with its own unique immersive logic:

In science and education settings, domes are the perfect translator of complex principles. For example:

• Planetariums use domes to simulate the movement of galaxies, allowing visitors to "stand at the center of the solar system" and observe the planets' revolution;
• Natural History Museums use domes to recreate the "Dinosaur Era," presenting a 360-degree visual depiction of the ancient forest ecosystem. Interactive dinosaur footprints projected on the ground allow children to intuitively understand biological evolution.

Theme parks use domes to address the pain point of the monotonous experience of traditional amusement facilities. For example:

• The dome attraction at Disney's "Star Wars: Galaxy's Edge" simulates faster-than-light flight as visitors board the "Millennium Falcon" spacecraft. The reclining seats and engine sounds transform the "interstellar journey" from fantasy into a tangible reality.
• The "Intangible Cultural Heritage Dome Theater" in a cultural tourism town in China uses 360° footage to showcase the millennial evolution of shadow puppetry. Visitors feel as if they've "traveled into the world of shadow puppetry" and can even "touch" the virtual puppet characters.
