In an interesting article by the Financial Times, both Idemitsu Kotsan and Sumitomo executives estimate that "2012 will be the year when OLEDs hits the big times".

Idemitsu Kotsan also says that they are working on a new way to 'spray' small-molecule OLED materials. The new method should be ready by 2015. Spraying OLEDs (instead of using vapor-deposition) will mean less material loss, and thus cheaper displays. It will also make it easier to fabricate large panels.

Sumitomo is focusing on blue lifetime, and say that they will reach 50,000-60,000 hours by March 2010. 

A few years ago, lifetime was the biggest issue with OLEDs, but it seems companies are showing very rapid advances. Dupont announced today that they developed new (third Generation) printable, solution process OLED materials.

The Green Gen3 material has over one million hours lifetime (that's over 100 years of constant use!) with 25 cd/A efficiency. The color coordinates are 0.26, 0.65. 

The light-blue Gen 3 (color coordinates 0.14, 0.12) has 38,000 hours from 1000 cd/m2, efficiency of 6.0 cd/A, and a lifetime of 38,000 hours. A deeper blue (color coordinates 0.14, 0.08) was developed with 7,000 hours. Due to its deep blue color, the lifetime of this material at the luminance required for a 200 cd/m2 display is calculated to be approximately 41,000 hours. 

The Gen-3 red has a lifetime of 62,000 hours, current efficiency of 13 cd/A, and color coordinates (0.68, 0.32). 

Scientists at the Pacific Northwest National Laboratory scientist have designed, synthesized and tested new blue OLED materials. They claim that these new materials have an improved efficiency - by at least 25 percent.

Plextronics announced today that its conductive ink has been shown to improve the performance of certain P-OLED devices.

BASF and Osram Opto Semiconductors have developed a highly efficient white OLEDs. The efficiency is over 60 lumens per watt, and meet the international Energy Star SSL standard for color requirements. 

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.

At their yearly share holder meeting, UDC reviewed their company's and the OLED industry's progress. UDC also highlights continued adoption of its energy-efficient PHOLED technology in commercial displays and advances in its flexible OLED, white OLED lighting, and printable, phosphorescent P(2)OLED(TM) technologies.

Universal Display’s Chief Executive Officer, Steven V. Abramson, began the meeting by reviewing progress in the commercialization of the Company’s OLED technologies over the past year. Mr. Abramson followed this by highlighting advances in next generation technologies for display and lighting applications, and providing a vision of the future for the Company and the OLED industry.
