In the future, newspapers could be just a flexible computer screen made out of thin plastic, if a prototype developed recently proves successful.
Scientists with computer and printer maker Hewlett-Packard and Arizona State University's Flexible Display Center have come up with what they claim is an unbreakable active matrix computer screen that performs very similar to a laptop computer screen.
Mass production of such displays could make laptops, smart phones, and other electronic devices less expensive since the display is one of the more costly components.
While they are not commonly found in stores, flexible displays are being developed as an alternative to rigid glass screens. One such technology called organic LED (OLED) uses a film of organic chemicals about an inch thick, that when excited; turn an electronic signal into a viewable image.
The HP-Arizona State prototype is made up of a layering of computer chip materials and metals that can be rolled out like a paper towel, but uses 90% fewer materials and is less expensive to build than other flexible displays currently available.
"The display HP has created with the FDC proves the technology and demonstrates the remarkable innovation we're bringing to the rapidly growing display market," Carl Taussig, director of Information Surfaces at HP Labs, said in a statement. "In addition to providing a lower-cost process, [this] technology represents a more sustainable, environmentally sensitive approach to producing electronic displays."
To build a strong and functional flexible screen, scientists started with stacks of semiconductor materials and metals imposed onto a flexible plastic film called Teonex Polyethylene Naphthalate, which was made by DuPont Teijin. Then layers of electronic ink called bi-stable electrophoretic imaging film are imprinted through a special lithography process and arranged so that the images can be seen with very little electricity.
Researchers suggest that these flexible electronic displays can be used for a new generation of portable devices, including e-readers and similar products.
Industry analysts with one firm expects that as the cost to make flexible displays goes down the number of devices using them will grow from $80 million in 2007 to $2.8 billion by 2013.
Personally, I think it would be nifty to be able to read the latest news on a flexible display and then be able to check sports scores and weather without having to turn a page.
It is good for flexible computer screen. User can use depend of require of screen. Some happen the problem of big and small screen. It is choice of changeable or flexible screen by the user. It will develop HP and Arizon University.
