Παλιά καραμέλα αλλά όλο και πλησιάζει και θα αλλάξει τη ζωή μας! Aκόμη δεν έχουμε δεί τίποτε! Όπως κάποτε κανείς δεν είχε φανταστεί το web έτσι και εμείς έχουμε να δούμε ακόμη...

Super-thin screen brings e-paper a step closer

The latest in e-paper: Electronic circuits on a flexible stainless steel foil - thin, though not yet quite thin enough to be folded in half
Electronic paper which promises to change the face of publishing, came closer to reality this week, as scientists in the U.S. revealed a super-thin, flexible electronic-ink display screen.
The development is reported by Yu Chen and colleagues from E Ink Corporation in Cambridge, Massachusetts in the today's issue of the journal Nature.
Just 0.3 mm thick, the device developed by Chen and team can be flexed without distorting the type and paves the way for electronic newspapers, wearable computer screens and smart identity cards.
"It's the closest thing demonstrated today to electronic paper," Chen, an electrical engineer at E Ink and a visiting scientist at Princeton University in New Jersey, told Reuters.
Fully developed, e-paper would display black and white and colour text and be capable of using its wireless technology to get regular updates through the Internet - a feature which could make buying the daily newspaper no longer necessary.
"In the current form you can already receive images and read books through these display screens," Chen said. The display was, however, currently still too slow for video because of the switching speed of the electronic ink, he added.
The display consists of two components. The front part switches according to electronic signals and the back component is a circuit made of transistors that control each individual pixel that composes the display. Each pixel needs a circuit, made of transistors, behind it to switch it. In order to make electronic paper the transistors have to be made on a very thin and flexible substrate.
"In our case it is a very thin stainless steel foil. You need to put a layer of electronic circuits on that foil," Chen said, adding the size can vary from a business card to a computer screen. The current device is too thick to be folded in half but Chen and his team are working on a thinner a version.
"Our work demonstrated that you can make high-quality electronic circuits on very thin and flexible substrates," he added.
