E Ink Mobius is the latest offering from E Ink. It features a flexible substrate.


[edit] Overview

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.

[edit] 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.

[edit] 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.
