This is possible because of this flexible displays technology’s proprieties. It consumes very low energy, only when it is used, and allows the manufacturing of extremely thin and flexible displays.
Hitachi W61H can be found only in Asia at the moment, featuring the 2.7-inch E Ink display called Silhouette Screen, an internal main WQVGA display of 2.8 inches with 240 x 400 resolution, a built-in 1.97MP camera, 2GB microSD maximum memory, and a 4-hours battery.

The news for today is that Casio and Hitachi are launching cell phones with E Ink screens but featuring flexible displays, according to the latest press release from E Ink Corporation.
They use the E Ink Vizplex Imaging Film technology for an entire cell phones line, which will be the world’s first flip phones with e-paper-based displays.

“We wanted features such as outdoor sunlight readability, 180 degree viewing angle, extremely thin, rugged, flexible display that consumed very little power,” said Satoshi Shirasawa, Marketing Manager for CHMC. “E Ink’s electrophoretic display technology provided all that and more, something we could not get from other display technologies.”

KDDI, the company providing the services for Hitachi W61H will serve also the new Casio Model G’zOne, an impressive handset that will appear on the market later this summer, featuring the Silhouette display characterized by a wide viewing angle, increased readability in sunlight, ruggedness, very thin form factor, and the very low power consumption, increasing the battery life.

“Fashion is a key driver in today’s world,” said Sriram Peruvemba, Vice President of Marketing, E Ink Corp. “E Ink offers a smart surface that changes the design and brings mobile phones to the fashion forefront of technology.”

Now that’s a cool cell phone, but unfortunately as all the other cool models it is launched in Asia.
It is the Hitachi’s W61H with 2.7-inch E-Ink display.

The main display though is Silhouette Screen capable of showing 95 preset graphics, and there is also the second main display, a 2.8-inch WQVGA type of 240 x 400 pixels resolution.

The cell phone integrates a 1.97MP camera plus 2GB microSD memory but that’s it, you can’t extend this one.
Its battery lasts for over 4 hours in working time.

The most important feature of the W53H, is the One Seg digital TV tuner, which supports EPG (Electronic Program Guide), a guide to television programs, that permits the user to navigate through programs and select what he/she wants, using criteria like title, channel, time and genre, all these with the use of the keypad.

The GPS navigation system, the Media player, the SD card slot for up to 2GB external memory and the Infrared support, are the main features of this beautiful model.
And let’s not forget about the 2MP built-in camera.

The availability of the phone will start in December in Japan, at a price of just $85.

It comes equipped with a 2.1 megapixel camera with auto focus, 2.6 inch large 240×400 TFT display, 512MB of internal memory, Memory Stick Pro Duo card slot, a media player, and a host of business applications (photo, text, document viewer).
