Jin Sung-Ho, a chemistry professor at Pusan National Univeristy in South Korea, say they have succeeded in devloping efficient true-blue OLED materials. The project was state funded, together with Seoul National University.
MicroOLED and CEA-LETI developed a new OLED microdisplay that sports the world's smallest pixel size. The OLED is a 9.6mm WVGA, with over 1.7M sub-pixels. MicroOLED's technology is based on OLED IP licensed from Thomson and CEA.
Hodogaya Chemical and Novaled have agreed to offer hole transport materials (HTM) for Novaled PIN-OLED structures. Hodogaya has exclusively developed specific HTM for Novaled fitting very well with the Novaled PIN OLED structures. As a first result Novaled is enhancing its material offer with an additional hole transport material called NHT18.
The new NHT18 has a similar behavior in OLEDs like NPB, but provides additional advantages to OLED manufacturers. For example, the Tg of NHT18 is above 130C and thus gives a high temperature stability in OLED devices. The current efficiency in today's fluorescent blue emitting PIN OLEDs is 10% higher.
At FPDI, Lumiotec gave some more info on their OLED Lighting products. The panels are only 2.3mm thick, and the has high
color rendering properties and a broad spectrum with peaks in red (R),
green (G) and blue (B) regions.
The company employed a technology called "multi-photon emission (MPE),"
which uses several emission layers stacked vertically. The product on
display had vertically stacked three emission layers with different
emission wavelengths for RGB colors.

CMEL introduces a New OLED manufacturing technique called Metal encapsulated module (MEM). MEM displays are thinner (0.7mm instead of 1.7mm), lighter, and stronger.
CMEL showed a 25" AMOLED 'MEM' TV, and they say that it can be used on displays of any size. They plan to start offering such displays in Q2 2009. In fact they will offer the option of MEM on all their displays, so customers can choose (so we assume MEM displays will cost more than traditional OLEDs).
Attached below is a short datasheet on MEMs.
Samsung has shown their new 4" Flexible AMOLED (480x272, contrast 100,000:1, 200cd/m2 luminence). It is very thin - 0.05mm in fact - that it 'flaps' in the wind (Samsung placed it near a fan...).
Samsung calls it the 'flapping display'. They claim they can actually make it thinner, but it's a bit difficult.
To achieve this thickness, Samsung etched an OLED panel that uses a normal glass substrate. The drive circuit was formed by LTPS TFTs. Also, low-molecular organic EL materials were employed.
The panel was not sealed by a glass substrate but by membrane sealing technology using a sputtering method. That's why the 0.05mm thickness is almost the thickness of the drive circuit board.
Researchers working in the European ROLLED project have developed a flexible OLED element that can be mass produced using roll-to-roll printing technology. The OLED elements can be used to add value to product packages. The new method is considerably cheaper than the traditional manufacturing method. The project was coordinated by VTT,and project participants included INM, CSEM, Ciba, Hansaprint, UPM and PolylC.
ROLLED project flexible element prototype
The OLED element developed under the ROLLED project is made from organic materials and is encapsulated in a moisture barrier film. The element is 200-250 micrometers thick, the equivalent to three or four sheets of paper.
A research group of the Dresden Technical University (together with Novaled) has achieved record energy consumption for OLEDs. The achievement brings the organic LED technology closer to industrial volume production, and these OLEDs are prototyped at the Fraunhofer ITMS.
The research team achieved an efficiency of 26, 22 and 3.1 percent for red, green and blue organic LEDs which combined form a white light source. The low efficiency for blue results of physical differences â while red and green OLEDs are phosphorescent light sources, their blue counterpart is a fluorescent one, resulting in lower light emission. The difference, however, can be compensated for by increasing the active size of the blue light emitter as well as sending a higher current through it, explained research group member Rico Meerheim.

Merck KGaA today announced the completion of an agreement to acquire the entire intellectual property (IP) portfolio of the company OLED-T with immediate effect. As we reported last month, OLED-T has gone into liquidation. We don't have any information on the financial side of this agreement.
OLED-T had an IP portfolio in the field of electron transport and phosphorescent-emitting materials for OLED application.
