Lectum® – the world’s first flexible, glass-free EPDs

Plastic Logic designs and manufacturers flexible, glass-free electrophoretic displays (EPDs). Available in various sizes and with mono and colour options, designers can select exactly the right displays for their application needs.

Flexible, shatterproof, lightweight

Lectum® displays are the first flexible, glass-free electrophoretic displays (EPDs) in volume production.

Being completely made of plastic, Lectum® displays are much more rugged than standard glass-based EPDs. They are also thinner and lighter per square inch than conventional EPDs and are inherently low-power, which is vital in today’s increasingly mobile world.

Our high-resolution e-paper displays are available in a wide range of sizes, from very small to the current maximum size of around A4.

Benefits for application designers

With Plastic Logic’s Lectum® displays, product designers can access production-ready, flexible displays which can be integrated into a wide range of applications, including smart cards, smart wearables, mobile devices and digital signage.

Plastic Logic also provides Evaluation Kits for our displays so that designers and end-users can quickly and easily evaluate our technology for specific applications. Just get in touch to find out more.
