European cities must modernize public services while cutting energy demand, and communication infrastructure sits at the heart of that challenge. E Ink ePaper reflective displays draw power only when the image changes, letting cities deliver transit updates, wayfinding, notices and advertising on battery- or solar-powered signage. With the EU Energy Efficiency Directive pushing public-sector energy targets, ePaper offers a low-power alternative to printed signs and always-on digital screens.

The 4th ePaper Industry Innovation Conference (ePIC 2026) closed in Shenzhen with 300+ guests and a 1,200 sqm ePaper zone. Based on the event and on a dataset of 67 global ePaper "first" products released from 2007 to 2026, five trends emerge: full color is now a real product track, consumer (B2C) innovation leads, AI has become a default feature, ePaper is shifting from a screen to a surface, and upstream platform technologies are breaking through in clusters.
