Pervasive Displays adds duo to extend red tri-colour e-paper displays

E-paper display provider, Pervasive Displays (PDi),has added two display sizes to its red tri-colour EPD line-up. The 3.7-inch and wide-format 4.37-inch models can both render high-quality images and text in red, white and black, says the company.

The additional size options give product and service designers more flexibility when choosing displays, typically for use where there is no access to mains power. Unlike conventional TFT LCDs, e-paper displays only consume energy when the display content is changed; maintaining a static image requires no energy at all. When they do occur, screen update uses relatively little energy, meaning e-paper displays can be powered using either a small battery or harvested energy.

This power source flexibility means that they can be used in logistics tags, ID and visitor badges, e-labels or IoT sensor node status screens, where the content only need to be updated sporadically.

The displays have driving waveform and respective pixel densities of 130 dpi (3.7-inch) and 117 dpi (4.37-inch), to render sharp and detailed images and text. Pervasive Displays pre-programs key capabilities into the displays so that they can be driven without consuming resource from the host controller.

A built in timing controller contributes to the slimness of the displays’ footprint, allowing more space for other components or the ability to minimise the overall product size.

Pervasive Displays designs, manufactures and markets e-paper displays for applications requiring high resolution, good readability and low power consumption. The company focuses on commercial and industrial applications including retail, logistics, healthcare, security and manufacturing. Its mature TFT, integrated circuit and e-paper platforms reduce risks and improve product value.

Standard and custom displays are offered, together with  technical support through an ecosystem of partners. Design resources include detailed product specifications, application notes, reference designs, source code and applications support.

Pervasive Displays is based in Tainan City, Taiwan and has offices in The Netherlands and Oregon, USA.
