New materials continue to be developed with very strong increases in performance: blue lifetimes announced at 26,000 hours from an initial luminance of 1000 cd/m². Green now achieves 200,000 hours and red up to 350,000 hours.
CDT has over 560 patents granted worldwide in 280 families.
Device Development Centre is founded in Ehime, Japan
CDT acquires the assets of Next Sierra, Inc., a Mountain View, California-based hardware developer that specializes in designing P-OLED/OLED display driver chips.
CDT demonstrates a 160 ppi, wide format, three-inch, full-color display incorporating CDT’s P-OLED technology at SID 2007. The high resolution display was printed at CDT using Litrex Gen 2 inkjet printers on amorphous Si TFT substrates provided by Casio.
Cambridge Display Technology wins the Organic Semiconductor Industry Award for Research and Development for its development of Total Matrix Addressing – an innovative device driving technique with the potential to alter the economics for driving high-resolution passive-matrix displays – potentially of benefit to both small molecule and polymer devices.
Lifetimes now quoted from 1000 cd/m² as green P-OLED materials demonstrate lifetimes of 50,000 hours. Blue materials have now been developed with a demonstrated lifetime 10,000 hours from an initial luminance of 1000 cd/m².
Sumitomo Chemical Company, a long-term partner of CDT, acquires CDT on the 19th September 2007.
CDT awarded Jean-Pierre Noblanc Award for Excellence for its participation in a multi-national collaborative project.
Lifetimes now quoted from 400 cd/m² as performance continues to improve. Blue fluorescent lifetime now 25,000 hours (equivalent to 400,000 hours from 100 cd/m²). Red phosphorescent devices attain 98,900 hours from 400 cd/m² (equivalent to 400,000 hours from 100 cd/m²).
Seiko Epson announces world’s first P-OLED printhead for use in printers, scanners etc.
Toppan Printing and CDT show roll printed display at SID 2007 – another world first.
CDT commences work on top emission displays, in which light emerges from the cathode side of the device.
Sumitomo acquired Dow Chemicals P-OLED assets, including key polyfluorene IP. Sumation™ joint venture established with Sumitomo Chemical for the development and production of materials and inks.

“Blue lifetime” reaches 150,000 hours at 100cd/m².
CDT progress on performance of blue materials continued to improve rapidly. Lifetimes to half brightness are now over 80,000 hours from 100 cd/m², thus opening up many new display product possibilities.
CDT floats on NASDAQ.
CDT announces a dramatic improvement to the lifetime (time to half brightness) of display devices based on P-OLED technology, with 20,000 hours of operation for its blue polymer research devices from 100 cd/ m². The advancement in blue devices is seen as a significant step towards the commercial exploitation of P-OLED technology in consumer applications.
Sumitomo Chemical and CDT form joint development project to create high efficiency materials using dendrimer technology, this will be especially important for the development of products requiring low power consumption.
CDT announces completion of its new 1,750 square meter US$25 million Technology Development Centre in Godmanchester, U.K. The heart of the centre is a 600m sq. state-of-the-art cleanroom, comprising class 100 and class 1000 areas.

CDT is founded by Cambridge University and seed venture capital.
First working displays developed (3 x 5 pixels)
Initial discovery of organic electroluminescence from polymers. A research group at the Cavendish Laboratory of Cambridge University (Prof. Donal Bradley, Prof. Richard Friend, Dr. Jeremy Burroughes) discovers that light could be produced from conjugated polymers. Patents are filed and a paper is published in Nature.
