Flexible Active Matrix

Mobius is a new flexible display that uses flexible TFT technology that is better suited for large format ePaper devices, allowing designers to create a rugged, lightweight device.



The size of the display is one of the biggest determining factors on a product size. The weight of a glass based TFT grows as the square of its diagonal dimension. This can significantly affect the end weight of a device. However, plastic-based TFTs eliminate the need for glass, and can significantly reduce the weight of a display. A 13.3″ EPD using Mobius weighs ~63g. In contrast, a 13.3″ glass-based EPD display weighs 144g.


Technology Challenges

However, there are several challenges to manufacturing TFTs on non-glass substrates. E Ink and many other companies have worked on flexible displays for several years, and Mobius is the first plastic-based TFT product offered by E Ink in mass production. Sony developed this revolutionary new TFT technology, in partnership with E Ink. Mobius displays consist of a plastic TFT laminated to an E Ink front plane laminate (FPL).


Lowest Power Consumption

E Ink makes the lowest power displays in the eReader industry. Mobius displays are just as low power as other E Ink Displays. Unlike other technologies, E Ink is bistable, which means it needs no power to hold an image or page of text.
