Geniatech showcased its latest partial color E Ink screen refresh technology at ISE 2025, demonstrating a new driver board based on E Ink Spectra 6. Unlike conventional solutions that rely on standard TCON driver chipsets, Geniatech has developed its own FPGA, allowing for a more flexible and efficient way of updating content on E Ink displays. This approach results in higher DPI and a smoother experience, particularly for applications like digital menu boards, where only selective parts of the screen need to be updated rather than refreshing the entire display.

One of the key innovations of this system is its ability to perform non-rectangular partial updates, meaning that only specific elements—such as a price or a dish name—can be refreshed without affecting the rest of the content. This significantly improves user experience by reducing flickering, a common drawback in traditional E Ink updates. In practice, this means that restaurant menus, retail displays, and other digital signage applications can dynamically update individual sections without redrawing the entire page, leading to a smoother and more natural-looking transition.
Geniatech’s approach also enables more efficient power usage, although the primary goal of the technology is to enhance display performance rather than minimize energy consumption. The ability to target updates to specific areas of the screen helps maintain clarity and eliminates unnecessary redraws, making it particularly useful for scenarios where information needs to be updated frequently but without causing distractions.
The company believes this market has substantial growth potential, especially as industries look for sustainable alternatives to paper-based solutions. Even if only a small percentage of traditional printed signage is replaced with E Ink displays, the impact could be significant. The flexibility of Geniatech’s API allows for seamless integration into content management systems (CMS), enabling businesses to easily update their displays through web-based platforms.
Technically, the system requires precise control of every pin on the display, which Geniatech has achieved through its proprietary driver board design. This level of control enables more efficient and cost-effective large-scale color E Ink displays, making them more viable for mass adoption. In addition to the driver board, the company is also developing supporting hardware, including the player board and BSP (Board Support Package), as well as cloud service integration for remote content management.
Geniatech envisions a future where regulatory measures, particularly in the EU, could encourage businesses to adopt low-power display technologies. With sustainability and energy efficiency becoming key factors in consumer and business decisions, E Ink solutions provide an eco-friendly alternative to conventional LCD and LED displays. The technology is particularly well-suited to outdoor use, where glare-free, paper-like readability is an advantage over traditional backlit screens.
The demonstration at ISE 2025 was an early-stage prototype, rapidly developed just days before the event. While optimizations such as reducing reflections on the display are still in progress, the core functionality is already promising. As development progresses, Geniatech aims to refine the display quality to closely resemble real paper while maintaining the advantages of digital adaptability.
By combining proprietary hardware, optimized firmware, and cloud-based content management, Geniatech is positioning itself as a leader in next-generation E Ink signage. The potential for widespread adoption spans multiple industries, from hospitality to retail and beyond. With a focus on improving performance, reducing costs, and supporting sustainability efforts, this technology could help drive a significant shift towards more energy-efficient digital displays.
