Pervasive Displays (Pdi) is strengthening its red tri-color EPD line-up with the launch of 3.7-inch and wide-format 4.37-inch models, both able to render high-quality images and text in red, white and black.

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.
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. Because Pervasive Displays pre-programs key capabilities into the displays, they can be driven without consuming resource from the host controller.
