Experience E-Ink with Lumina Displays Welcome to the Lumina Displays E-Ink experience. This app has been created to accompany a special promotional E-Ink display, gifted by Lumina Displays to a select group of customers, partners and industry colleagues as our way of saying thank you. But this is more than just a gift. We wanted to give you the opportunity to experience E-Ink technology for yourself — to see how content can remain beautifully visible on a display while consuming an incredibly small amount of energy. Discover E-Ink Using the Lumina app, you can interact with your promotional E-Ink display, explore its capabilities and experience first-hand what makes this technology different from conventional digital displays. E-Ink technology is particularly unique because it requires very little power to maintain an image on screen. Once content has been displayed, it can remain visible without the continuous power consumption associated with traditional illuminated displays. The result is a display technology that opens exciting possibilities for applications where energy efficiency, sustainability, visibility and simplicity are important.
