Rugged EPDs address emerging application opportunities

Pervasive Displays has further expanded the range of possible use cases that its products can support through the launch of the new Armor offering. EPDs based on the company’s unique Armor technology can deliver greater mechanical robustness and increased sunlight readability characteristics. This suggests they can be optimised for deployment in more challenging semi-outdoor environments – with units able to prolonge operation while still achieving industry-leading image quality.

Armor is being made available as an option for all of its’ EPD size formats ranging up to 12″. Among the places where these EPDs can be employed are in the designs for handheld equipment, public information systems and digital signage equipment, freight container labelling, shop floor conveyor systems, warehousing operations, and more.

For its 2.66″ format EPD, the Armor version is able to withstand ball drop tests with an impact force up to 2.105J. This is almost 40 times more impact resistant than an EPD without Armor which can withstand around 0.053J of impact. Further elevated levels of protection can be delivered by the series through a selection of higher cost materials. The ability to cope with low temperatures (as low as -25C) allows these EPDs to meet the demands of food packaging, laboratory and warehouse settings.

As Alchin Wang, president, Pervasive Displays, explains: “There are a multitude of applications that require an effective way of showing detailed information, but where conventional TFT displays will draw too much current and drain their batteries too quickly. EPDs present an energy-efficient alternative. However, until now, there have been very limited EPD options on the market that are able to deal with difficult operational conditions, as they are prone to deterioration due to UV and humidity exposure, as well as ongoing wear and tear. This has limited the scope of applications that EPDs can be used in. However, Armor now enables us to supply our customers with a ground-breaking solution unmatched by our competition in terms of robustness, and this will open up new possibilities.”
