The more versatile mobile device

Reading and accessing information on the move has become the norm.
However, it can sometimes be a frustrating experience for users,
between trying to read in bright sunlight, coping with low battery through
prolonged use and cracked screens.

Glass-free electronic paper displays utilizing electrophoretic technology
can offer a versatile solution to these problems.

Increased functionality with shatterproof epd

By integrating a secondary display in the back of a smartphone or a tablet, manufacturers can double the surface area for apps, screensavers and important information, such as mobile boarding cards.

And by choosing a glass-free Lectum® display, device fragility is halved whilst doubling functionality; our plastic electrophoretic displays (EPD) are extremely robust and shatterproof so your customers can enjoy twice the device real estate for reading, working, texting and gaming – even in bright sunlight, where EPD far excels other display types - but without an increased risk of breakage when dropped.

  • robust and shatterproof glass-free displays
  • ultrathin display allows designers to maintain expectations for thinner devices
  • lightweight: double the surface area without doubling weight
  • low power for longer use
  • suitable for integration in smartphones, tablets and eReaders

Thinner and lighter devices

Because Lectum displays are plastic displays, the additional weight is incremental, which is critical when designing a mobile device. Compared with standard, glass-based EPD, Lectum displays are lighter per square inch.

Flexible, glass-free EPD for mobile devices

Low power for extended use

Tablets, eReaders, smartphones and mobile accessories alike can benefit from the integration of a Lectum display, which have inherently low power consumption, being EPDs. This means more hours of non-stop reading, or having your mobile boarding card to hand, even when your smartphone battery has already failed on that long transatlantic business trip.

Extensive experience in mobile device design

We have worked with customers on a range of products and bring a wealth of experience in the integration of EPD in mobile devices. Several reference designs are available for your convenience. We also offer bespoken display solutions.

Mobile devices - FAQ


Do Lectum displays have touch?

Lectum displays are not equipped with a touch sensor as standard. However, we have extensive experience in the use of touch sensors with our EPDs and are happy to support our customers in the integration of our displays with touch into their end applications.


How much power do Lectum displays require?

Our Lectum displays are truly bi-stable meaning power is only needed for an update and not to show a static image. The energy required for a typical image update depends on the display size and driver chip setup; starting at just a few mJ per update for smaller displays, allowing battery-less NFC applications. For details please refer to the respective datasheet.


Can I power a Lectum display using NFC?

NFC refers to near field communication, which is a technology enabling simple and safe contactless, two-way interactions between electronic devices, typically up to a distance of 4 cm. Lectum displays based on the Ultrachip platform can be updated using NFC.


Which size displays are available?

Plastic Logic Germany manufactures and sells EPDs in a range of sizes and configurations. You can find detailed information on our offering here.


What if I require a different sized display to those offered on your website?

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.


What is electrophoretic technology?

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.


What is a bi-stable display?

A bi-stable display makes use of a bi-stable technology, in this case electrophoresis. The image on a bi-stable display is retained and can be read without a power supply, meaning that any device using such a display is generally deemed to be “low-power”. For example, an eReader only uses battery power when the user turns a page and not when the content is static and being read, which is why many of these devices can claim to have a battery life of up to several weeks between charges. (N.b. eReaders do also require battery power for connectivity, touch, standby and any front light.)
