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. Both E Ink Pearl and E Ink Carta screen technologies are supported.
There are two benefits. The screen and substrate are basically unbreakable and the screen is much lighter making the device much lighter. The screen exhibits some limitations for some users. For example, the fact that it is flexible causes some to think it my be breaking if they place any pressure on it. It is basically unbreakable. The second problem is that there may be minor scratches when using the stylus. The solution is to add a screen protector to the device and replace it when needed.
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.
