[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. Both E Ink Pearl and E Ink Carta[1] 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.

[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.
