The Sharp ePaper Display operates with a remarkable zero power consumption during content playback, drawing only minimal power when content changes. This innovative technology represents a new era in energy-efficient signage solutions and a groundbreaking step toward carbon-neutrality.
As a digital alternative to paper posters, the Sharp ePaper Display is ideal for presenting static content which is updated regularly. Applications such as POS promotions, menu boards and allergen information in retail and hospitality environments, and timetables, check-in and gate information in transportation environments – the possibilities are vast! Where up to date information needs to be conveyed, the Sharp ePaper display provides an enhanced communication method offering compelling cost saving efficiencies.
The term ePaper, or electronic paper, very accurately describes what this technology is. It has a paper-like quality with excellent readability in bright ambient light, without reflections. With full-colour capability enhanced by ACeP colour performance, ePaper delivers outstanding visual performances with excellent contrast, wide viewing angles, and fine resolution for an ergonomic content presentation that looks remarkably like a poster.
Currently available in two sizes, the EP-C131 (13.3”) and EP-C251 (25.3”), Sharp/NEC is continuously innovating to bring to market larger sizes to open new applications for this highly energy efficient technology. At ISE 2025, Sharp/NEC introduced new larger sizes, A3 (20”), A2 (28”), A1 (40”), and an A0 (57”) outdoor compatible solution featuring solar power, battery storage and wireless communication functionality. Referencing the size using DIN standard format in entirely appropriate for ePaper’s target market where posters are the traditional medium.
Although E-ink technology has been around for a number of years in smaller and monochrome formats and even some basic colour applications, the evolution of Advanced Color e-Paper (ACeP™), allowing reproduction of high-quality full colour images, is widening application potential. An innovative approach by Sharp/NEC has reinvigorated the technology with the potential to transform digital signage by enhancing efficiency, sustainability and the user experience.
ePaper technology has no backlight and therefore has no energy demands during content playback. This characteristic is what makes ePaper comparable to paper in that it requires light to reflect upon its surface to make it visible – you wouldn’t read a newspaper while sitting in the dark. The brighter the ambient light, the brighter the content appears.
When a signal is sent to the display, electromagnetically charged particles respond by moving across the surface to display the appropriate colour. Similar to the printing process, the colours cyan, magenta, yellow and reflective white (CMYK) merge to create up to 50,000 different colours. Once in place, these particles hold their charge for up to two years without any power feed. Only when the content changes does the display require power allowing the particles to rearrange themselves to create new colours.
When required, the ePaper Display receives power via USB-C. There is space to integrate either an optional battery such as a standard power pack, or a PoE to USB-C adapter, without compromising the already slim profile of the unit. Since the display does not need to be positioned close to a power socket, it offers almost unlimited versatility in terms of installation possibilities.
There are several methods available to change the image depending on the number of displays to be updated. An integrated System on Chip supports seamless, secure and flexible content management options. The most basic deployment for a single display is via USB-C cable connection to a PC, or simply insert a USB drive to speed up the setup of multiple displays. An easy-to-use online settings tool allows the user to control Wi-Fi network access and to manage and schedule a playlist. Alternatively, a mobile app allows the ePaper display settings and content to be changed on a mobile device via Bluetooth. Sharp/NEC is partnering with an increasing number of third-party CMS providers to widen applications for larger estates.
Key benefits of ePaper technology
Sustainability
ePaper technology offers a more sustainable approach to static content display by offering a digital alternative to paper posters. By reducing reliance on traditional paper, businesses can cut down on waste. They can avoid printing and warehouse costs plus the logistical efforts and cost involved in distribution and ensuring the poster ends up in the right place at the right time.
Efficiency
Moreover, by digitising the poster, the process of changing content is instant. This not only saves time but also reduces the impact of human error. ePaper offers an element of proof of play which cannot be provided by paper posters which rely on a long chain of people and processes to get in front of the right eyeballs.
Impressive ROI
The sustainability and efficiency of ePaper leads to significant cost savings over time. As part of their evaluation process, a customer who prints instore promotional material has calculated the ROI of ePaper verses printing to be 2-3 years. As a long-lasting product, the savings from years 3-4 onwards are compelling.
Enhanced communications
Where dynamic always-on displays are inappropriate, and yet up to date information needs to be conveyed, ePaper offers an enhanced method of communication. For example, the University of Hertfordshire has installed 100 ePaper displays in its new high-tech Spectra building attached to laboratory doors to update health and safety information – vital messaging conveying the risk status impacting the wellbeing of students and staff.
Versatility
ePaper is ultra lightweight. It can be hung like a picture frame or placed on a table stand. For more permanent installations it features VESA mounting. Portrait, landscape, face up, face down; ePaper is endlessly versatile and does not need to be positioned near a power outlet. Its wide application potential has yet to be fully realised!
Ease of Use
Changing content is easy. Sharp/NEC provides a very simple to use online settings tool enabling the user to effortless set up the ePaper Display, customising and configuring parameters for multiple displays from one central location. Alternatively, a mobile app allows the user to very simply change settings and upload images to the ePaper Display by connecting a mobile device via Bluetooth.
