At Plastic Logic, we are proud to be the acknowledged leader in the design and manufacture of flexible, glass-free electrophoretic displays (EPD).
Our glass-free flexible Lectum® displays are lightweight and ultra-low-power.
Having perfected and industrialized our patented process for the manufacture of glass-free backplanes and flexible ePaper displays, we now have proven product in the market.
From smarter smart cards to more wearable wearables. From more versatile mobile devices to the lowest power and most readable digital signage.
Our glass-free ePaper displays are the driving force behind a wide range of new and different products.

Our expert team’s extensive experience, as well as our great success in flexible electronics manufacturing has made us one of the world’s leading companies in the field.
A deep knowledge of process industrialization, as well as a profound understanding of display and device development, means we are best placed to serve and support our customers.
To prove the technology a bespoke pilot factory was built in Dresden, Germany. That proven technology is now being implemented with world class TFT manufacturers around the world.
There is no difference. They are in fact synonymous! EPD stands for electrophoretic display, which is often also referred to as “ePaper”. (N.B. Some people use the acronym for electronic paper display.)
ePaper (also known as e-paper, electronic paper and electronic ink) is a display technology developed to show text on a screen and mimic the appearance of ink on paper in printed books. ePaper is reflective. This means it reflects light, just like paper, making it generally more comfortable to read and providing a wider viewing angle than in the case of conventional backlit flat panel displays, which are light-emitting. Many ePaper technologies allow text and images to be held on a display for an infinite period of time without electricity.
Electrophoretic technology refers to the process whereby thousands of microcapsules, containing (negatively charged) black and (positively charged) white pigments suspended in a clear fluid, are encapsulated in a plastic sheet.
When a charge (positive or negative) is applied, the corresponding particles move to the top of the microcapsule and the surface appears black or white in this specific area. When the charge is removed, the particles stay where they are. This is called bi-stability: where something can rest in either of two states.
In the case of an EPD, the text and/or images remain on the screen until the next update and the user can continue to view the content without the need for battery power. This means EPDs are inherently low-power and is one of the main differentiators to conventional backlit flat panel displays, where a constant power supply is required to maintain content.
Durable, flexible displays have been made possible by our leadership in plastic electronics technology and our development and industrialisation of the organic thin film transistor (OTFT).
Plastic Logic is the first company to manufacture transistor arrays (basically a matrix of transistors) on plastic instead of using silicon on glass. This means that flexible backplanes can be coupled with a flexible display medium, such as electronic ink or OLEDs, to create a fully flexible display.
Unlike conventional glass-based EPDs, Lectum displays are plastic based and therefore the only truly flexible, active-matrix EPDs on the market. They have a typical bendability radius of 50 mm.
We also offer tailor-made display solutions in addition to the reference designs listed in our product portfolio. Custom projects are subject to NRE and a minimum order quantity.
