Scent Display Terminal ScentScreen Launches: Screens That Release Matching Aromas

Japan's ScentTech launches consumer-grade scent display device with 48 base aroma molecules that can combine to produce thousands of scents synchronized with screen content.

Japan's ScentTech unveiled ScentScreen in Tokyo on February 28 — the world's first consumer-grade scent display terminal. Shaped like a small speaker placed beside a monitor, the device uses 48 base aroma molecule capsules to synthesize and release scents matching screen content within 3 seconds.

ScentScreen's core technology is the "scent pixel" system. Each base aroma molecule corresponds to an independent microfluidic injection unit. By precisely controlling each unit's injection ratio and timing, over 2,000 different scents can be combined. The built-in AI engine analyzes screen images or video content to automatically select matching scent combinations.

"Watching a cooking show and smelling the aroma, watching a documentary and smelling the forest — this isn't science fiction," ScentTech CEO Tanaka Hiroshi said at the launch.

During testing, ScentScreen was adapted for Netflix, YouTube, and three major games. Netflix has produced scent synchronization data files for 50 popular documentaries and cooking shows. Users can also manually adjust scent concentration or disable the feature.

ScentScreen retails for $299, with scent capsule refill packs costing approximately $15 per month. The first products launch in April in Japan, South Korea, and Singapore, with European and American markets expected to follow in June.

However, scent display technology has also sparked health discussions. Some test users reported mild headaches and allergic reactions, and ScentTech advises users with respiratory sensitivity histories to consult doctors before use.
