Door signs and room displays that barely use power.
Meeting-room and office signs change a few times a day. E-paper holds the image without power and updates when the schedule does. Room booking from LUMA AI Studio starts field samples in November 2026 and launches officially at ISE in February 2027.
The schedule changes, the sign follows.
Room schedules and notices come from the e-paper content system — or, from 2027, LUMA AI Studio room booking. The sign updates when the schedule changes and holds the image in between without power.

Where this hardware works.
Common applications by industry, and the setup we would typically build for each. Every project starts from your site, so sizes and parts change with it.
Meeting-room door signs
The sign at the door shows today's bookings and whether the room is free.
- Typical setup
- A battery e-paper sign per room, with the schedule from the e-paper content system.
- What matters here
- No cable at every door, readable at a glance.
Room booking at the door
Staff see the schedule and book a free room on the spot.
- Typical setup
- A small touch display at the door with LUMA AI Studio room booking — field samples from November 2026, launch in February 2027.
- What matters here
- Booking where the meeting happens.
Floor directories and wayfinding
Floor plans, tenant lists and directions in the lobby and on each floor.
- Typical setup
- 25.3" or 32" e-paper boards in the lobby, 13" signs in corridors.
- What matters here
- Clear in bright light, on almost no power.
Work instructions and status boards
Work instructions, kanban cards and process status at each station, updated when the plan changes.
- Typical setup
- E-paper boards at the stations, updated over Wi-Fi.
- What matters here
- Changes a few times a shift, on almost no power.
Room and ward signs
Signs at rooms and wards show schedules, the care team and notices.
- Typical setup
- 13" e-paper signs at doors and larger boards at nurse stations.
- What matters here
- Quiet, glare-free and easy to update.
Posters and menus on e-paper
Promotions, menus and product information on e-paper posters that change without reprinting.
- Typical setup
- 25.3" or 32" e-paper boards, with battery models where there is no outlet.
- What matters here
- A paper-like look with no printing and almost no power.
One team, from the board to the software.
A typical rollout stitches together a board vendor, a panel supplier, a firmware contractor and a software team. We design the board, build the display and write the firmware ourselves, then integrate your software — so when something has to change, one team changes it.
