E Ink Mobius
E Ink Mobius is the latest offering from E Ink. It features a flexible substrate.
The new flexible electronic paper display (EPD) technology will be the first flexible display technology that will go into mass production for a large format digital paper product and utilizes a flexible Thin Film Transistor (TFT) technology developed by Sony for plastic displays and turned over to E Ink. E Ink Pearl screen technology is employed.
It can also be used with a glass overlay. When a screen breaks it is usually the back TFT layer that breaks, not the outside layer which can be made more rugged. Having a glass overlay permits a front light and a more sensitive touchscreen.
 13.3" screen
The Mobius display is featured in the Sony E Ink slate device. It is a 13.3" inch display with 150 ppi and 16 grayscale layers. It has 1600 x 1200 pixels. See screen sizes for a comparison. The display is approximately 271 x 203 mm or 10.67" x 8.0" providing near letter size reproduction and is only 4.8mm thick (less that .2").
This will make the display much more rugged and also significantly lighter, 63grams vs 144grams for glass.
 6" rugged screen
The earliest use of this flexible display was the WEXLER. Flex ONE on a 6" eBook reader. This screen is planned in Earl. The Earl development team mentions: PVI, E-Ink’s Taiwanese parent company has sent them some samples of their new flexible screen. The new screen uses the E-ink’s Regal waveform technology which dramatically reduces the need for refreshes, allowing for a smoother viewing experience.
