Tainan City, Taiwan – 16 June 2021. Pervasive Displays has introduced the new Armor offering, expanding the range of use cases for its e-paper displays (EPDs). Armor EPDs achieve greater mechanical robustness and improved sunlight readability. They are optimized for challenging semi-outdoor environments, delivering industry-leading image quality during prolonged operation.

Armor Technology

Provided as a custom option, Armor is available for all Pervasive Displays’ EPD size formats up to 12-inch. Armor EPDs suit handheld equipment, public information systems, and digital signage. Other applications include freight container labelling, shop floor conveyer systems, and warehousing.

Each Armor EPD module features an optically-bonded cover lens — made from PMMA or tempered glass — and a UV filtering layer. The proprietary protective sheet makes Armor modules ten times more resistant to humidity than competing solutions, and safeguards them from scratches. The protective sheet and edge sealant resist heat-related expansion and contraction, preventing cracking. As a result, the EPDs resist moisture ingress that would otherwise shorten their lifespan. A resin board attached to the rear alleviates deformation risk from external impact.

Performance and Protection

For Pervasive Displays’ popular 2.66-inch format EPD, the Armor version can withstand ball drop tests with an impact force of up to 2.105J. This is nearly 40 times more impact resistant than an EPD without Armour which will withstand around 0.053J of impact. Further elevated levels of protection can be achieved by the series via selection of higher cost materials. The ability to cope with low temperatures (reaching down to -25°C) allows Armor EPDs to address the needs of food packaging, laboratory and warehouse settings.

As Alchin Wang, President of Pervasive Displays, explains: “Many applications need an effective way to display detailed information. But conventional TFT displays draw too much current and drain batteries quickly. EPDs present an energy-efficient alternative. Until now, very few EPD options could deal with difficult operational conditions. Most are prone to deterioration from UV exposure, humidity, and wear and tear. This limited the scope of EPD applications. However, Armor now enables us to deliver a ground-breaking solution unmatched by our competition in robustness, and this will open up new possibilities.”
