Review Display Systems (RDS) Builds Bespoke E-Ink Solutions for the Toughest Environments

E-paper (E-Ink) is no longer just about e-readers. In industrial, retail, medical and transport applications, its unique combination of daylight readability, near-zero power consumption when static, and bi-stable imaging makes it the perfect display technology for environments where LCDs and OLEDs fail.

The challenge? Most suppliers only offer catalogue products. At Review Display Systems (RDS), we believe industrial customers deserve better – fully custom E-paper solutions engineered from the panel outwards. Let’s talk about some possible deployments of this technology and how RDS can help you bring your ideas to market.

1.  Electronic Shelf Labels for UK & European supermarket groups

Across thousands of stores, paper price tags could be eliminated. RDS has a complete family of 2.13″, 4.2″ and 7.4″ tri-colour (black/white/red or black/white/yellow) E-paper panels that:

• Can operate down to −25 °C in freezer aisles using low-temperature panels
• Include capacitive touch for in-aisle staff functions
• Achieve 5–10 year battery life via ultra-low-power designs
• Use custom protocols to integrate with the retailer’s existing gateway infrastructure
• Mount tool-free on standard shelf rails inside IP67-sealed housings

2.  Reusable Patient Identification Wristbands – ideal for medical applications in hospitals and the NHS

Traditional paper or plastic hospital wristbands become illegible and require constant reprinting. E-paper technology allows for flexible E Ink patient wristbands that are:

• 2.1″ bendable E Ink panels that conform to the wrist
• Medical-grade PCAP touch that works with examination gloves
• Fully sealed, antimicrobial casing with tamper-evident clasp
• Integrated wireless charging coil (no ports, no connectors)
• Dual-mode NFC + Bluetooth 5 on a curved custom PCB
• Over 12 months between charges and <2 second update time

3.  Zero-energy-cost public transport information displays –  UK and European bus & rail operators

Many historic or remote stations cannot have new power or data cables installed. RDS can build systems based on 31.2″ and 42″ colour E Ink Kaleido solar signage systems that:

• Run 100% from integrated 120 W solar panels and super-capacitor storage – no batteries to replace
• Update remotely via 4G/LTE with eSIM and GPS
• Withstand −20 °C to +70 °C using high-temperature E Ink Triton variants
• Feature vandal-resistant, anti-glare front glass and IP66 metal enclosures

Why RDS is Different

Very few distributors worldwide have genuine in-house display and electronics design capability. RDS is one of them.

• UK engineering headquarters plus dedicated teams worldwide
• Full mechanical, electronic and firmware design using the latest CAD and embedded tools
• Direct, long-standing relationship with supplier – we can request and qualify non-catalogue panels (special sizes, extended temperature ranges, new colour variants)
• Complete vertical integration: touch integration, custom driver boards, casing design, wireless stack (BLE, LoRa, 4G/5G, proprietary 2.4 GHz, NFC), power management (solar MPPT, wireless charging, super-caps), and all required certifications.

Is E-paper right for your next project?

If you need displays that are:

• Perfectly readable in direct sunlight
• Consume almost no power when the image is static
• Survive freezers, factories, hospitals, deserts or off-grid locations
• Last 10–20 years without backlight degradation…then modern industrial E-paper is ready – and RDS has the expertise to make it fit your exact requirements.
