ECO-Sign modules are low power E-paper displays devices that are wirelessly updated from a central point, with a local router/coordinator then communicating with a number of individually or group addressable units within range.

The system consists of:
  • An EPD display with the ability to display images received wirelessly
  • A Router/coordinator that can receive data via USB or TCP/IP from a PC
  • An application SW with pre-defined templates that uses the data provided by the end user to update the display
A complete reference design

We have an ECO-sign Demonstration system using a 7.4″ EPD housed in wall-mountable black plastic, with a receiver and rechargeable battery. These are accompanied by a router and a PC application with templates for meeting room reservations.
