uink Launches E-Paper Display Solutions for IoT Applications

As the Internet of Things continues to grow, the industry has become highly efficient at collecting and visualizing data, while new application scenarios continue to expand how that information is delivered at the physical edge.

Across factories, hospitals, campuses, offices, hotels, and transportation hubs, IoT systems now generate a constant stream of operational information: device status, schedules, inventory levels, alerts, instructions, and wayfinding. Sensors capture it, platforms process it, and dashboards analyze it. Yet at the physical edge, where people need to see and act on this information, many organizations are still relying on printed paper or power-hungry digital screens.

This growing disconnect has led to a shared industry challenge:

How do we make IoT data visible everywhere it’s needed, without adding power, wiring, and maintenance complexity?

uink was created by Milesight to address this need, drawing on the company’s deep expertise in IoT connectivity and low-power endpoint design. With this foundation, uink brings that experience into e-paper displays, delivering a truly low-power, scalable display layer for modern IoT environments.

The Visibility Gap in IoT Deployments

For IoT decision-makers, the problem is familiar. Dashboards work well in control rooms, but not on shop floors. Tablets and LCD screens deliver dynamic content, but they require continuous power, regular maintenance, and fixed infrastructure. Printed paper is cheap and readable, but impossible to update remotely and error-prone at scale.

As IoT deployments expand from pilots into hundreds or thousands of endpoints, these trade-offs become harder to ignore. Information needs to stay visible 24/7, remain readable in bright environments, update when needed and do all of this without driving up operational costs.

This is especially true in environments where information changes occasionally, not constantly: a medication label in a hospital pharmacy, a production status card in a factory, a room schedule outside a meeting space, or a timetable at a transit stop. For years, these use cases sat in a gray area, too dynamic for paper and too inefficient for traditional screens.

A Different Approach to Edge Displays

uink introduces a portfolio of ultra-low-power e-paper displays designed specifically for information-centric IoT use cases. Instead of chasing animation, brightness, or video, the platform prioritizes persistence, readability, and efficiency.

E-paper displays hold content without continuous power. Once updated, information remains visible even if the device is offline or battery-hungry. This makes them well-suited to environments where wiring is impractical, power availability is limited, or maintenance access is infrequent.

More importantly, uink positions e-paper not as a standalone product, but as part of a broader IoT ecosystem that includes e-papers, gateways, management tools, and open integrations.

From Devices to a Scalable IoT Display Layer

With LoRa connectivity and low-power communication design, uink e-paper displays support long-range updates while maintaining minimal energy consumption. Content can be refreshed as needed through the uink management platform, making the solution suitable for structured, site-by-site rollouts as well as distributed deployments.

For organizations implementing IoT internally, this provides a manageable and predictable way to extend information visibility to the edge. For system integrators and IoT solution providers, uink e-paper displays can be incorporated into existing architectures as a dedicated, low-power display component within broader connected systems.

Connectivity and Display Portfolio

Beyond LoRa, uink supports multiple connectivity options including Wi-Fi, BLE, and Cat 1, enabling flexible deployment across different network environments. Organizations can select the most suitable communication method based on infrastructure availability, coverage requirements, and project scale, ensuring seamless integration into existing IoT systems.

uink’s display portfolio is designed to address diverse application needs across various sizes and use cases. The lineup spans compact formats such as 4.2-inch and 9.7-inch displays, mid-size 13.3-inch displays, and larger formats including 25.3-inch and 31.5-inch displays for more prominent information presentation. Across these sizes, customers can choose from monochrome e-paper for clear, high-contrast visibility, four-color models for enhanced visual emphasis, and advanced full-color displays for richer content communication. This breadth allows organizations to align screen size and display capability with operational requirements, from localized status indicators to larger, high-impact information boards.

Why This Matters Now

The timing of uink’s launch reflects broader shifts in the IoT market.

First, sustainability is no longer a side conversation. Energy consumption, lifecycle cost, and environmental impact are now central to infrastructure decisions. Displays that draw power continuously, even when showing static content, are increasingly hard to justify.

Second, IoT deployments are moving out of controlled environments and into real-world, people-facing spaces. The need for human-readable, always-on information is growing faster than the tools designed to deliver it.

Finally, the industry is maturing. Organizations are less interested in flashy pilots and more focused on solutions that scale quietly, reliably, and cost-effectively over time.

In this context, e-paper is not a new technology, but its role as a dedicated IoT display layer is only now coming into focus.

Looking Ahead

As IoT systems continue to grow in scale and complexity, the industry will need to rethink how information flows from machines to people. The challenge is not collecting more data, but presenting the right data, in the right place, at the right time without unnecessary cost or complexity.

uink’s e-paper platform is positioned as one response to that challenge. Not by adding more screens, but by rethinking what an IoT display should be.
