TL;DR
An independent developer has created a fully functional E-ink monitor capable of 60Hz refresh rates, a significant breakthrough for the technology. This development could expand E-ink’s use beyond e-readers into computer displays.
An independent developer has successfully created a 13.3-inch E-ink monitor capable of 60Hz refresh rates, a significant advancement in E-ink display technology. This development challenges the long-held view that E-ink screens are inherently slow, opening the door for their use in computer monitors and other high-refresh applications.
The breakthrough was achieved by developing a custom controller that overcomes the limitations of traditional E-ink drivers, which were originally designed for low-power, slow-refresh e-reader applications. According to Hackaday, this controller enables the display to refresh at 60Hz, making it suitable for dynamic content and computer use.
The project, called Modos Flow, is fully open-source and includes a 13.3-inch monochrome and color version available for purchase through Crowd Supply. The developer’s work was motivated by the desire to use E-ink in a laptop, which required faster refresh rates than typical E-ink screens could provide.
Initial testing showed promising results, with the display maintaining high resolution and readability while achieving the desired refresh rate. The development involved significant optimization to balance appearance and responsiveness, and the project has been presented at Hackaday Supercon 2024.
Potential Impact on E-Ink Display Applications
This development could significantly expand the use cases for E-ink displays beyond e-readers, including monitors, portable devices, and low-power screens for various applications. It demonstrates that the perceived limitations of E-ink are primarily due to controller design rather than inherent technology constraints, which could lead to broader adoption and innovation.

Historical Limitations of E-Ink Refresh Rates
E-ink displays have traditionally been used for e-readers because of their low power consumption and readability in bright light. However, their refresh rates have remained slow, typically below 1Hz, due to controller limitations rooted in their original design for static content. Attempts to improve refresh speeds have been hampered by vendor restrictions and the technology’s focus on low-power operation.
Recent efforts, including this new controller design, challenge these assumptions and demonstrate that higher refresh rates are technically feasible. The project builds on prior research into custom controllers and open-source hardware, aiming to make E-ink more versatile for modern digital applications.
“The controller we developed can push E-ink displays to refresh at 60Hz, which was previously thought impossible without sacrificing resolution or readability.”

Remaining Technical and Market Challenges
While the prototype demonstrates promising performance, it is not yet clear how well the technology will scale for mass production or commercial deployment. Long-term reliability, power consumption at higher refresh rates, and vendor support remain untested factors. Additionally, the extent to which this approach can be adapted to different E-ink models or integrated into consumer products is still uncertain.

Key Questions
Can this E-ink monitor be used as a regular computer display?
Yes, the 60Hz refresh rate makes it suitable for general computing tasks, though it is primarily designed for static or slow-moving content given E-ink’s nature.
Will this development make E-ink displays more mainstream?
Potentially, if the technology proves reliable and scalable, it could expand E-ink’s use cases into monitors, e-readers, and portable devices.
Are there any limitations or downsides to this new controller?
Long-term durability, power consumption at higher refresh rates, and vendor support are still unknown and require further testing.
Is this technology available for purchase now?
The Modos Flow monitor is available through Crowd Supply in monochrome and color versions, but the fully optimized, mass-market version is still in development.
How does this compare to traditional LCD or OLED monitors?
While LCD and OLED screens support high refresh rates and color, E-ink offers advantages in low power consumption and readability in bright light, making it ideal for specific use cases if the technology matures.
