ITRI is showing a flexible 4.1 inch flexible AMOLED Display. The Taiwans Industrial Technology Research is announcing that this new prototype is more flexible and softer than the devices before.
John Chen, general director of the Display Technology Center at ITRI says also:

"We think OLED will work better than other technologies. There's no need for a backlight or a polarizer nor stacks of optical film," he added.

Samsung show a new Video about their flexible OLED. The 2.8 inch flexible Amoled does have 166ppi and is 20 micrometer thick.

LG Display unveiled an e-book that is equipped with in-house developed solar cell.

The thin-film solar cell featured in the e-book measures 10 centimeters in width and length, it was developed to perfectly fit the 6-inch display panel for e-book currently mass produced by LG Display. The solar cell measures 0.7 millimeter in thickness and weighs a mere 20 grams, the less thickness of a credit card and the weight of a fountain pen.

The video shows it all but the "laptop" has a flexible OLED display that is also capable of multitouch. When rolled out it becomes a 17-inch flat screen but can also be folded into a 13-inch tablet of sorts.
The device of the flexible display allows a new concept in notebook design growing out of the traditional bookformed laptop into unfurling and convolving portable computer.

On top of everything else all computer utilities from power supply through the holding belt to an interactive pen are integrated in Rolltop. This is really an all-in-one gadget.

Sony will demonstrate a 2.5 inch flexible OLED screen prototype with 0.2mm thinness that incorporates a flexible organic thin film transistor to drive its display at CEATEC 2009 in Japan.
Sony does not show a new OLED Television prototype.

Sony is also showing some other interesting new technlogies at the CEATEC-2009 event in Japan:

High frame rate "MotionFlow"

Kodak demonstrated the their flexible OLED Display under water!
OLEDs are notoriously moisture-sensitive, so this is quite an achievement for the Kodak researchers team.
Flexible OLEDs have the potential to be a game-changer for the display world, realizing a unique form factor at lower cost. They also have broad applications in the lighting industry.

The Plastic Electronics Foundation and IntertechPira announce the agenda for this year’s Plastic Electronics Europe 2009 Conference and Exhibition. The show takes
place 27-29 October 2009 at the Maritim Hotel & Conference Center in Dresden, Germany, and provides a vital platform where science and industry can meet to drive forward commercialisation in organic electronics.

Prof. Kyung Cheol Choi and his korean research team discovered the surface plasmon enhanced spontaneous emission based on an OLED Device.

Advance Flexible OLEDs closer to mass market thanks to Universal Display and the Flexible display center.

Universal Display will showcase display and lighting product prototypes, and share technical information and advances that illustrate the inherent energy efficiency, smaller carbon footprint and environmental benefits of the company’s PHOLED technology and materials for displays and lighting.
