Samsung’s newly launched 32-inch Color E-Paper (EM32DX) consumes “0.00 W” while holding a static image, yet offers 60 000 colours—enough for complex fare tables, bank queue numbers or multi-segment dashboards. news.samsung.com
Why it matters
- Battery-free installs – A built-in battery plus solar trickle means posters can hang cable-free for months in transit hubs.
- Segment-friendly refresh – The 60 Hz partial-update mode lets designers overlay crisp numeric segments for schedules or pricing without ghosting.
- Sustainability edge – At < 84 kWh/year of embodied energy, Samsung claims a 70 % carbon cut versus back-lit LCD signage. news.samsung.com
E-paper vs. classic segments
Whereas a seven-segment LED speed sign uses 20–40 W continuous, Samsung’s e-paper keeps power near zero between updates—a compelling trade-off for venues needing frequent but not real-time changes.
Roll-out timeline
Pilot deployments begin Q4 2025 with European transit agencies; SDKs exposing “segment overlay” objects ship alongside the Q3 firmware drop.
