Liquid OLED for curved, longlife displays and many creative solutions

I wrote a post earlier on flexible OLED but that was more limted than the newest version. read the press release below

19 August 2009

Researchers at a Japanese University have developed a groundbreaking OLED technology that is claimed will significantly ease the creation of curved displays and drastically improve their lifespan. Denghui Xu and Chihaya Adachi, from the Center for Future Chemistry at Kyushu University in Fukuoka have created “liquid-OLED”, according to information and news website, OLED-info.com

volutionary design has a liquid centre and can be easily curved. SlashGear reported that Xu and Adachi had injected a mixture of electrically-conductive liquid and photoluminescent solid rubrene between an anode and cathode. That was then sandwiched in glass to produce lighting in the same way that an OLED with a solid luminescent layer does.

Another advantage, according to the Japanese scientists, is that by utilising a recirculating system the fluid OLED layer could be refreshed, thereby extending the lifespan of the display.

The scientists will, however, have to overcome a problem with the light output of the liquid-OLEDs. Apparently, although the light output is visible to the naked eye, it does not currently match that of traditional OLED display products.

Samsung Mobile Display show 6.5 inch Flexible AMOLED Display

Samsung Mobile Display (SMD) show a new 6.5 inch flexible AMOLED Prototype. SMD show this newest flexible AMOLED at the SID 2009 in San Antonio. Samsung Mobile Display say that this prototype is more flexible than any previous model before.

Also SMD says that the new processes do not require low-temperatures to produce the display and productions costs are now lower than other competitive products. The new process is simpler and improves efficiencies necessary for mass production.

SMD sees many application for that flexible AMOLED (newspaper,epaper, e-passport, military maps, newspaper and many more. The reponse time is more than 1000 times faster as a LCD Panel.

New this year at SID 2009 will be seven sessions dedicated exclusively to various aspects of flexible display technology and developments that will create a host of new business and revenue opportunities across not only consumer-electronics markets, but also military and industrial applications. Papers from the Flexible Display Center, Kent Displays, Polymer Vision, Prime View, Universal Display Corp., Samsung, Sharp and Sony along with several key universities like the University of Illinois will highlight work underway at every level of the flexible display food chain.

Japanese researchers developed rubber-like OLED
05/11/2009

University of Tokyo researchers developed a new kind of OLED display, that can actually stretch and deform - like rubber.They showed one displays that is shaped like a face, and showing changing expressions, and another screen that is spherical and shows weather data. The OLEDs were produced by spraying a layer of carbon nanotubes with a fluoro-rubber compound to produce a stretchy, conductive material.

The current prototypes are 100 sq centimeters, and have 256 monochrome pixels. They can be folded at least a thousand times, with no decline in quality. They are working towards better resolution and color displays.

"In the future, displays that once had to be flat can be made spherical, or even moving," says Takao Someya, professor of electronic engineering at the University of Tokyo. "A human-shaped display could be used to show medical diagnosis data, and there are various other applications."

Kyocera Unveils Kinetic Flexible OLED Cell Phone

Charting the future of cell phone technology, Kyocera recently unveiled a kinetic energy-powered phone that is capable of folding up like a wallet. Designed by industrial designer Susan McKinney, the EOS phone consists of a soft, semi-rigid polymer skin surrounding a flexible low-energy OLED display. Shape memory allows the phone’s keys to pop up when in use and blend in with the surface during downtimeThe Kyocera EOS can be used in its folded-up shape for simple phone calls, unfolds to reveal a wide screen, and we were excited to hear that the it derives its energy from human interaction. The more you use the phone, the more kinetic energy is turned into an electric charge through an array of tiny piezoelectric generators. In other words, you’ll never have to worry about leaving the house with a semi-charged cell phone again.

The EOS is still in the early design stage, but Kyocera teams in San Diego and Bangalore hope to integrate concepts from the device into cell phone lineups in the near future. Maybe future

Flexible Displays Get Touch Friendly

Last year, the Flexible Display Center showed off the first prototypes of displays so thin and light they can be rolled up and stuffed into your Levis or North Face backpack.
Now, the Center is saying it is ready with a touchscreen version. The touchscreen capability has been enabled by integrating a low-power display from E Ink and Epson, say researchers. E ink's technology also powers Amazon's Kindle and Sony's e-book reader.

Flexible diplays, or paper thin displays made almost entirely of plastic were of the biggest technology breakthroughs of 2008. The low-power displays are rugged, sunlight-readable, light weight and will allow users to enter, store and transmit real-time data, said Nick Colaneri, director of the Flexible Display Center in a statement.

The Center housed at Arizona State University has been working with the U.S. Army to create these

displays that could be available in limited field trials in about two to three years.
The flexible touchscreen display supports user input either by stylus pen or by touch. It consumes power only when the electronic paper is activated. Once sketched on the display, information can be stored or sent wirelessly before erasing.

Companies have already started working on creating manufacturing technology processes for these displays. In December, HP said it created the first prototype of an "affordable" flexible electronic display. HP's manufacturing process would allow flexible displays to be created using roll-to-roll manufacturing, much like how a newspaper is printed in the press. The move would reduce production costs, said HP.

the portable projection screen will be the projector as well:)

It's sad we have to wait for about 10 years but this would be great. The projection screen will become the projector as well so no more ugly devices in the design interior. Just roll up the TV:) Besides of this there are plenty other great applications you can think about when being able to use flexible OLED. I wish they would sell it on rolls just like wall paper.

Technology breakthrough paves way for flexible OLED

Highly flexible displays are just round the corner, following a breakthrough in the use of carbon-based graphene. A group of South Korean researchers, headed by Byung Hee Hong, developed a way to “spray” graphene, a material derived from carbon nanotubes, on thin pieces of nickel that are dissolved before attaching the film to a PET polymer.

The graphene is tipped for use in OLED screens, adding momentum to the technology that originally took off in 2007 when it started to be selected for screens in popular gadgets, such as mobile phones and MP3 players.

Although graphene, a material that is one atom thick and maintains electrical conductivity, was orginally produced in 2004 it was extremely cumbersome to make in bulk. However, Byung Lee Hong‘s team claim, in a paper published in prominent scientific journal, Nature, their new technique can produce strong, flexible, conductive sheets, suitable for mass-production.

And whilst scientists are busy working on ways to commercially produce flexible displays, a quick look at Las Vegas‘ CES show demonstrates that major industry players are also ploughing money into flexible OLED technologies. Sony showed off concepts that included a video bracelet and a one screen laptop, with touch screen keyboard. Not to be outdone Samsung unveiled a PDA that opened up into one large screen for watching video.

Finally, the US Army is backing flexible display technology, funding research at Arizona State University's Flexible Display Center. The military want to create small, portable, flexible screens that can provide its soldiers with situational information on a battlefield.

Although projections suggest we won’t see this kind of technology commercially developed, on a large scale, for perhaps another 10 years the research and funding dedicated to the technology indicates people are serious about bringing flexible displays to market.
