Wake, draw, sleep
The panel wakes on a timer, checks for new content, updates the image and powers down. Ten minutes is the default interval.
E-paper
E-paper display software that runs on almost no power.
An e-paper panel keeps its last image with the power off, and it stays readable in bright sunlight. Shelf edges and room signs that change a few times a day suit it well. Wallboard runs these panels from the same console as your other screens. Each one wakes on a schedule, fetches its next image, draws it and goes back to sleep.
What Wallboard does on e-paper.
Keeps showing when offline
Content is cached on the device. If the server is unreachable, the panel keeps its last image and uses the stored settings.
Reports back every cycle
Each wake-up uploads metrics, logs, proof of display and a screenshot, so you can see what each panel shows.
Updates itself
The app updates automatically. Set a version limit and the time windows when updates may install.
Supported e-paper displays.

Other Android e-ink devices
These may work, but we have not certified them. Test one before a rollout.
Settings you control.
Wake schedule
Set a fixed sleep time, or wake at exact times with a cron expression such as noon every day.
Working hours
Outside set hours the panel skips wake-ups and waits for the next allowed time, which saves more energy.
Power off or sleep
Between cycles the device can power off completely and use no energy, or sleep and use very little.
Emergency content
Assign emergency content to e-paper devices, the same as any other screen.
Orientation and fit
Rotate the image to match how the panel hangs, and choose how pictures fit the frame.
How it works
How it fits together.
Install and register
Install the app, and the panel shows a four-digit code. It sleeps two minutes between checks until you register it.
Build e-paper content
Make an e-paper playlist of still images, or assign a slide. A slide with video or GIFs is captured as one still frame.
Assign it
Assign the playlist or slide from the device settings. The panel picks it up the next time it wakes.
Tune the cycle
Set the wake interval, working hours and power mode. Changes apply at the next wake-up, never between.
Plan an e-paper rollout.
Tell us which panels you have and how often their content needs to change. In the demo we’ll set a wake schedule that fits, and our support team stays on hand through the first install.
