TL;DR
An anonymous researcher has developed a custom controller that allows a 13.3-inch E-ink display to operate at 60 Hz. This breakthrough challenges the traditional limitations of E-ink screens, opening new possibilities for low-power monitors.
A custom controller has successfully enabled a 13.3-inch monochrome E-ink display to operate at 60 Hz, a significant increase from typical refresh rates. This development, confirmed by Hackaday, marks the first time such a high refresh rate has been achieved for E-ink screens and could revolutionize their use as computer monitors, especially for low-power applications.
Traditionally, E-ink displays have been limited to slow refresh rates, primarily due to their controller technology, not the inherent display technology itself. The recent breakthrough was achieved by an anonymous researcher who designed a custom controller capable of managing a 13.3-inch E-ink panel at 60 Hz. This is a notable departure from standard E-ink refresh rates, which are often below 1 Hz, making real-time display of moving images or interactive content impractical. The development was driven by the desire to adapt E-ink for use as a computer monitor, which requires higher refresh rates for smooth visuals. Initial tests with the custom controller produced promising results, leading to plans for a fully open-source, user-repairable portable E-ink monitor called Modos Flow, available through Crowd Supply. The project faced challenges such as optimizing display modes and overcoming vendor-related delays, but the core achievement remains the high refresh rate capability. The technology is still in early stages, and commercial availability or widespread adoption is not yet confirmed.
Potential Impact on E-Ink Display Applications
This development could significantly expand the applications of E-ink technology beyond e-readers, particularly in low-power, always-on displays, and portable monitors. Achieving 60 Hz refresh rates allows for smoother visuals and even basic interactive use, which was previously unfeasible with traditional E-ink controllers. If adopted broadly, it could lead to a new category of energy-efficient computer monitors and signage, reducing power consumption compared to LCD or OLED screens. Furthermore, open-source efforts like the Modos Flow demonstrate the feasibility of DIY and small-scale manufacturing, potentially disrupting existing supply chains and encouraging innovation in low-power display tech.

Limitations of Traditional E-Ink and Recent Innovations
E-ink displays have long been valued for their low power consumption, readability in bright light, and durability, but their slow refresh rates have limited their use in dynamic or interactive applications. Historically, these screens were designed for e-readers, where static images are common, and refresh rates below 1 Hz sufficed. The primary bottleneck was believed to be the display technology itself; however, recent developments suggest that controller design is the key factor. The creation of custom controllers capable of higher refresh rates is challenging but has gained momentum, culminating in the recent achievement of 60 Hz operation. This progress was first demonstrated in prototype form and is now moving toward commercial and DIY projects, such as the Modos Flow monitor.
“The key to unlocking high refresh rates on E-ink displays is the controller, not the display technology itself.”

Remaining Challenges and Adoption Uncertainties
While the high refresh rate has been demonstrated in prototype form, it is not yet clear whether this technology can be scaled for mass production or integrated into commercial products. Long-term reliability, compatibility with various display modes, and vendor support remain uncertain. Additionally, the availability of the custom controller design and whether it can be adopted widely are still to be seen. Further testing and development are needed to confirm performance in real-world scenarios and to establish manufacturing standards.

Next Steps Toward Commercial Use and Broader Adoption
The developer plans to release the open-source controller design and collaborate with hardware manufacturers to refine the technology. Additional testing will focus on durability, image quality, and power consumption. Consumer-ready products, such as the Modos Flow monitor, are expected to become available through crowdfunding platforms like Crowd Supply in the coming months. Industry adoption will depend on further validation, manufacturing scalability, and integration with existing hardware ecosystems.

Key Questions
Can this high refresh rate be used for color E-ink displays?
Currently, the development is focused on monochrome displays, but there are plans to explore color E-ink panels. Achieving high refresh rates for color displays remains more complex and is still in early stages.
Will this technology be available for consumer monitors soon?
While prototypes are promising, commercial availability depends on further development, manufacturing, and vendor support. It may still be several months before consumer-ready products are on the market.
Does this mean E-ink displays can now be used for video or gaming?
In theory, the higher refresh rate makes basic video playback more feasible, but E-ink’s inherent limitations in refresh speed and response time mean it is unlikely to replace traditional displays for fast-paced gaming or high-frame-rate video in the near term.
What are the power consumption implications of this high-refresh-rate E-ink?
Because E-ink displays are inherently low-power, maintaining low energy use at 60 Hz is a key goal. Early tests suggest power consumption remains minimal, but detailed measurements are still forthcoming.
