ZERO Power Displays
Energy-efficient, sunlight-readable display solutions.
Energy Efficient Displays
Zero Power Displays are transforming how visual information is delivered across outdoor environments, public transport, smart homes, and retail.
Using advanced ePaper and Cholesteric-LCD (CH-LCD) technology, they provide an energy-efficient alternative to traditional digital signage - reducing power consumption while maintaining clear, consistent visibility, even in bright outdoor conditions.
Their bistable design means power is only used during updates, enabling months or years of operation from battery or solar sources - ideal for low-power or remote applications.
- Zero power draw when image is static
- Readable in bright, outdoor environments
- Extended operational life with minimal energy use
- Available with low MOQs for rapid deployment
Colour Cholesteric LCD (CH-LCD)
A reflective, bistable LCD technology that retains images without continuous power, Colour CH-LCD delivers vibrant full-colour visuals without the need for a backlight, making it exceptionally energy-efficient.
- Lightening fast full-screen refresh in 200 milliseconds!
- Typical contrast ratio: 10:1
- Wide operating temperature range: -20°C to +60°C
- Available in 13.3", 24" (bar), 28.3” and 31.5" formats
- Available as display panel or in a fully enclosed unit, ready to go!
Perfect for ultra-low-power applications where colour visibility matters, including public information displays, retail promotions, and industrial labelling.
Sustainable paper-like display technology
Zero Power Displays are available in several formats to suit indoor and outdoor environments. All offer excellent readability in bright conditions, hold an image without power, and deliver a paper-like appearance.
E-Ink Spectra 6
A full-colour ePaper platform with a wider colour gamut and advanced imaging, ideal for high-impact retail and promotional content.
Monochrome ePaper
A crisp, high-contrast display that closely mimics printed paper, offering exceptional longevity, It's well suited to passenger information systems and shelf-edge labelling.
E-Ink Kaleido 3 Outdoor
A colour ePaper technology supporting 4096 colours and 16 levels of greyscale, making it ideal for maps, charts, and other visually rich outdoor applications.

A Truly Sustainable Technology
ePaper displays are significantly more environmentally friendly than traditional alternatives, producing up to 12,000 times less CO₂ emissions than LCD screens, and up to 60,000 times less than using paper.
By switching to low-power ePaper technology, retailers, advertisers, and public services can reduce their environmental footprint while still delivering dynamic, real-time updates with ease.
A smart step forward for organisations committed to sustainability, without compromising on performance.
Ideal Applications for Zero Power Displays
Shelf Edge Labels
Smart Pricing with Zero Waste
With paper-like clarity and no power draw when idle, e-paper enables digital pricing that’s easy to read, remotely updateable, and long-lasting -reducing waste and manual labour in retail environments.
Public Information
Always Visible, Always Efficient
e-Paper displays are perfect transport signage. They stay readable in direct sunlight, use no power between updates, and can run on solar -making them ideal for off-grid bus stops and transit systems.
Medical Patient Signage
Clear, Low-Power Room Info
ePaper displays are perfectly suited for hospital or care environments, displaying patient names, care plans, or room status.
Content remains visible without constant power, reducing energy use while maintaining a calm, readable bedside display.

Frequently Asked Questions
Below are some questions we get asked regularly. If there is anything else you would like to know, please contact us here:
How do zero power displays use no energy?
They are zero power when the image is static, relying on bistable display technology, meaning the screen only draws power during an image update. Once the content is set, ePaper and CH-LCD modules hold the image without ongoing energy
What’s the difference between ePaper and Cholesteric LCD technologies?
ePaper provides a paper-like, high-contrast display ideal for signage and labels and is available in different configurations, ie Black/White, Tri-Colour, 6 Colour but has a slower refresh rate, while Cholesteric-LCD (CH-LCD) delivers full-colour, sunlight-readable visuals with faster refresh rates when content needs to be changed. Both offer zero power static images, but are suited to different clarity, colour, and environmental requirements.
Are these displays suitable for outdoor environments?
Yes, both ePaper and CH‑LCD are inherently sunlight‑readable. Cholesteric LCDs operate a cross a wider temperature range than ePaper. Both maintain content with zero power draw, making them ideal for transport signage, wayfinding, and other outdoor applications.
Can these displays run on battery or solar power?
Absolutely. Because zero power displays only use energy during refresh, they can operate for months or years on small batteries or lightweight solar systems, even in off‑grid or hard‑to‑reach locations.
Which industries benefit most from zero power displays?
Applications span retail, public transport, industrial labelling, smart buildings, and healthcare, where organisations need energy‑efficient, low‑maintenance, and high‑visibility signage without the running costs of traditional LCDs.
Can Anders help integrate these displays into a full system solution?
Yes, Anders can pair zero power display technology with custom interface boards, single‑board computers, wireless modules, and embedded control systems to deliver a complete, application‑ready, production‑scalable solution.
What operating temperatures are supported?
Cholesteric-LCD (CH-LCD) currently have a wider operating temperature of -30 to +80°C whereas the eink’s Kaleido3 is ePD module built for outdoor usage with an operating temperature of -15 to +65°C.
How quickly can the display refresh?
Zero power displays can refresh in as little as 0.2 seconds for full colour CH-LCD. ePD displays are slower to refresh at 1-2 seconds for the Kaleido colour and up to 22 for tri-colour. These refresh rates are being reduced all the time to improve responsiveness.
