SCHWANDEN OB SIGRISWIL, Switzerland, 4 April 2025 — The future of immersive display technology shined bright during Parasigna’s visit to the Sternwarte Planetarium SIRIUS, where a major digital upgrade signals what’s next for high-impact visual experiences.

The planetarium recently transitioned from analog ZEISS ZKP4 projectors to advanced LED ZEISS VELVET units, marking a leap in contrast ratio, black-level depth, and full-dome clarity. The VELVET series—renowned for its absolute black projection (0.0 cd/m²) and native 4K resolution—offers capabilities increasingly sought after in high-end digital signage, especially for outdoor or low-light installations.

As a sponsor of the upgrade, Parasigna emphasized how the shift illustrates the evolution of signage from functional communication to experiential engagement. “This is a benchmark for how visual systems can not only inform but inspire,” the team shared.

During the visit, guests explored a digital night sky rendered with dazzling precision—highlighting celestial bodies like the moon, Jupiter, and Mars—under the guidance of a seasoned astronomy educator. The blend of storytelling and technical execution offered a preview of what’s possible when display technology meets purpose-driven content.

For professionals in digital signage, the SIRIUS upgrade is a reminder that display environments—whether on city streets or under a planetarium dome—benefit from investments in high contrast performance, color accuracy, and audience-centric design.

SIRIUS continues its outreach mission and seeks further support to expand public science education. Learn more or contribute at SIRIUS funding page.
