E Ink shows color, paper-like display

Martyn Williams at InfoWorld:

E Ink, a U.S.-based developer of electronic-paper type flat panel displays, has developed a color version of its screen technology and is showing it at the FPD International exhibition that opened Wednesday in Yokohama, Japan.

It’s based on similar technology to the company’s monochrome displays that are already in production and can be found in a handful of products like Sony’s Librie electronic book reader.

The main difference is the addition of a color filter. The prototype on display in Yokohama is a 6-inch display with 400 by 300 pixel resolution. That works out to 83 pixels per inch which is half that of the commercial screen used in the Sony e-book reader.

E Ink anticipates the display will be ready for commercialization at the end of 2006, said Bischoff. Potential applications include ATM screens, digital camera viewfinders, and mobile phones, he said.

The E Ink press release has more and some photos. Aside from the lightweight form factor,

E Ink’s electronic ink technology creates an image that looks like a printed page from all angles and maintains the same contrast ratio under all lighting conditions, including direct sunlight. Aimed at handheld devices, the display uses up to 100 times less energy than a standard liquid crystal display (LCD), so product designers can shed weight and greatly extend battery life.

Besides the color display, they are also showing a “tablet sized” greyscale display:

E Ink Corporation in USA, the leading supplier of electronic paper display technology, today announced that LG.Philips LCD, one of the world’s leading innovators of thin-film transistor liquid crystal (TFT-LCD) technology, and E Ink have built a 10.1″ flexible electronic paper display.

Less than 300 microns thick, the paper-white display is as thin and flexible as construction paper. With a 10.1″ diagonal, the prototype achieves SVGA (600×800) resolution at 100 pixels per inch and has a 10:1 contrast ratio with 4 levels of grayscale.

E InkĀ® Imaging Film is a novel display material that looks like printed ink on paper and has been designed for use in paper-like electronic displays. Like paper, the material can be flexed and rolled. As an additional benefit, the E Ink Imaging Film uses 100 times less energy than a liquid crystal display because it can hold an image without power and without a backlight.

No word on any applications or dates for this one.

    [...] We’ve mentioned E Ink before, and one of these days they’ll have color, but for right now the grey scale display seems to be fine for emulating books plus it can be electronically magnified up to 200% for the visually impaired. Since it’s not an LCD, it’s viewable from all angles and looks fine in sunlight. It really seems to be "electronic paper." [...]
