The Pixel Duo concept smartphone shows how the advantages of IPS and e-ink technologies could be combined in one device without drastically increasing the dimensions. Instead of the classic one screen, the Pixel Duo offers two, placed on the front, each with a completely different purpose.
In the upper part there is a 3.5-inch IPS screen with a resolution of 1280 × 800 pixels with a refresh rate of 120 Hz. This smaller LCD panel is used for video content, camera, quick web page navigation or display of widgets and clock. Thanks to high refresh rate and full color, the panel performs all tasks that require fluid animation and rich visual details.
Pixel Duoo combines a two-sided display for reading, video and work in two applications
Below it is a 5.2-inch e-ink screen with a resolution of 1300 × 838 pixels and a density of 300 pixels per inch. This panel displays only shades of gray, but is ideal for reading e-books, articles and long texts, as it is economical, easy on the eyes and consumes minimal energy. Since most applications would run precisely on this larger e-ink display, the Pixel Duo could achieve exceptionally long battery life.
The concept foresees the possibility of simultaneous work in two applications: video or music controls on the IPS screen, while reading a book or viewing documents on the e-ink panel below. Such dual organization of content shows the potential of a completely new kind of user experience.
The Pixel Duo remains just a concept for now and there are no plans for commercial production, but the idea clearly demonstrates how the combination of two fundamentally different displays can open up new directions in smartphone design, Notebookcheck reports.
