EPL-100 Controller Board for E-Ink

The Digital View EPL-100 controller board is designed for E Ink 25.3" and 28" epaper display panels. This low power interface accepts a bitmap image transferred over USB from a source media player such as a Raspberry Pi or Android PC. E Ink based displays are ideal for public signage, the significant benefits include the high visibility in bright environments as well as the ability to operate from solar power due to the very low power consumption.

Custom controller board layout with additional functions or integration is available as an engineering service. In addition Digital View can assist with display bonding and other integration requirements for the E Ink panel.

Software, Content Update & Media Players

As a public signage display, the normal system will have a media player, for example a PC, Android PC or Raspberry Pi. The Raspberry Pi model 3B or 4 is sufficiently powerful for most purposes so we have used it for further development. The following appnotes show example methods for updating the image using a Raspberry Pi Model 3 B+ together with the EPL-100 driver board and a compatible E Ink panel (NOTE: The applications referenced in these appnotes is available for free to EPL-100 customers):

- From PC to USB (PDF)
- Via Google Drive (PDF)
- Via network (PDF)

In addition we have been working with live data feeds, for example retrieving weather data from public sources, formatting it then writing it to the display.

Another function is partial screen update, this capability enables just updating the part of the display where the content has changed. This reduces the power used and can be useful for very low power installations.


As the E Ink panel is reflective and bistable it is uniquely suited to outdoor installations powered via a solar panel with rechargeable battery. Power reduction methods might include almost completely powering off the system and only powering up to perform intermittent content checks and updates. To facilitate this we have a pic processor powered timer relay
