What Is ePaper and How Does It Work?

ePaper (or electronic paper) displays mimic the appearance of ink on paper. They use electrophoretic technology, where tiny charged particles are rearranged using electric fields to create images. Unlike LED or LCD screens, ePaper doesn’t emit light—making it easier on the eyes and viewable even in bright sunlight.

Quick Summary:

  • Uses microcapsules filled with black and white particles
  • Displays are bistable (retain image with zero power)
  • Perfect for static or semi-dynamic content

Why Is ePaper Important for Digital Signage?

ePaper transforms digital signage by reducing energy use, improving readability, and enabling new use cases in places where power is limited or visibility matters most.

Key Benefits:

  • Zero power when idle
  • Sunlight-readable
  • Ultra-lightweight and flexible
  • Glare-free and high contrast
  • Eco-friendly with reduced carbon impact


Innovators like Philips and Sharp NEC and SOLUM have propelled ePaper into the spotlight with color displays and applications ranging from retail tags to outdoor billboards.

What Are the Top Use Cases for ePaper Displays?

Industry Application Example
Retail Electronic shelf labels, digital price tags
Transportation Real-time arrival boards at stations
Healthcare Room signage, status displays
Education Classroom schedules, e-bulletin boards
Corporate Meeting room signage, directories
QSR / Restaurants Dynamic menu boards (indoor/outdoor)

How Does ePaper Compare to LED/LCD Displays?

Feature ePaper LED/LCD
Power usage Extremely low Constant draw
Readability in light Excellent (no glare) Poor without backlighting
Content refresh rate Slower Instantaneous
Full video support No Yes
Color capability Limited (improving) Full-color

What Are the Drawbacks of ePaper?

  • ❌ Slower refresh rates (not ideal for video)
  • ❌ Limited color reproduction (though color ePaper is improving)
  • ❌ Higher upfront cost for hardware
  • ❌ Potential for ghosting on older models

What Trends Are Driving the Growth of ePaper in Signage?

The rise in sustainable tech adoption, dynamic pricing needs in retail, and real-time information in transportation and healthcare are pushing ePaper forward.

Emerging Trends:

  • Increased adoption of full-color ePaper (e.g., Philips Tableaux, SOLUM)
  • More integration with CMS platforms (like Wallboard)
  • Growing demand for sustainable signage options
  • Use in IoT and low-power smart environments

How Is Wallboard Integrating ePaper Technology?

Wallboard’s CMS natively supports ePaper displays with unique features like:

  • 🔁 Real-time data updates (not just static content)
  • 📸 Screenshot Mode for easy monitoring
  • 🧰 Easy installation tools and management with Toolbox
  • 💡 Front lighting support for dim environments
  • 📁 Organization with folders, tags, and smart search

Result: Digital signage that’s not only efficient but dynamic—unlocking new environments and use cases without sacrificing usability or brand control.
