If you want to design great wearable tech devices, you need to source the right components.
Wearable technologies need to adapt to form, not just function;
after all, technology shouldn’t wear the person, but rather it should be the other way around.

Flexible displays for wearable technologies

Our glass-free Lectum® displays are proven in the market and the perfect addition to any wearable technology designer’s toolkit: extremely robust and shatterproof, they allow wearables to withstand the wear and tear of daily device usage.

Being plastic displays, they are ultrathin, lightweight and flexible, making them well suited for integration in a host of wearables including smart jewelry, devices for mobile health monitoring, smart clothing and shoes.

Furthermore, being electrophoretic displays (EPD) and bi-stable, Lectum displays are intrinsically low power, since they only require battery when an image is updated. This reduces the required frequency for battery recharging and increases the potential use of thinner and/or printed batteries.

Smart jewelry

We have already worked with several smart jewelry manufacturers, developing wearable display solutions for their innovative products and proving that wearable technology doesn’t necessarily have to trade visual appeal for functionality.

Mobile health monitoring

Mobile health (mHealth) is almost certainly set to benefit from the growing wearable tech industry.

mHealth refers to the mobile collection and relay of clinical data to patients, practitioners and researchers, as well as real-time monitoring of patient vital signs and even direct provision of care.

Whilst relevant in industrialized nations, where the increase in aging populations requires additional, alternative forms of care to traditional methods, it is even more pertinent to developing nations, where patients often may not have immediate access to clinics and remote mobile treatment is the only option.

In all of these situations, patient monitoring devices need to be not only robust and lightweight, but above all have low power consumption.

Our shatterproof Lectum displays are the perfect fit for such devices: data is displayed dynamically and in high resolution, but without the battery drain associated with conventional LCD screens.

Wearable displays - FAQ

How flexible are Lectum displays?

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.

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.)
