The additional size options give product and service designers more flexibility when choosing displays, typically for use cases where there is no access to mains power. Unlike conventional TFT LCDs, e-paper displays only consume energy when you change what’s on the display, so maintaining a static image requires no energy at all. And because each screen update uses relatively little energy, e-paper displays can be powered using either a small battery or harvested energy.

This makes them a popular choice in a variety of applications where the contents of the display only needs updating sporadically such as logistics tags, ID and visitor badges, e-labels or IoT sensor node status screens.

With state-of-the-art driving waveform and respective pixel densities of 130 dpi (3.7-inch) and 117 dpi (4.37-inch), both can render sharp and detailed images and text. And because Pervasive Displays pre-programs key capabilities into the displays, they can be driven without consuming resource from the host controller.

Moreover, the displays’ slimline footprint, enabled in part by the built-in timing controller (Tcon), gives designers more space for other components, or the ability to minimize their overall product size.

Alchin Wang, CEO, Pervasive Displays, said: “Red EPDs provide a striking contrast that helps attract people’s attention and conveys critical information more quickly. Our red tri-color EPDs have been extremely popular, which is why we are expanding the range to give designers greater choice when selecting a display for their product.”

“And with speed-to-market a critical consideration for many customers, these displays are designed to be easy to integrate into end products, so they can be in customers’ hands as quickly as possible.”
