CAMBRIDGE, England, March 13 /PRNewswire-FirstCall/ -- Cambridge Display Technology (CDT) (NASDAQ:OLED) welcomes the announcement by Sumation(TM) -- its joint venture partner with Sumitomo Chemical -- of rapid progress in the development of long lifetime, high efficiency light emitting polymers for full color, video capable P-OLED displays.
Following a previous announcement in December, CDT now reports the achievement of blue fluorescent devices (CIEx=0.14, y=0.21) with 12,500 hours lifetime(1) from an initial luminance of 400cd/m2, and an efficiency of 9cd/A.
Also announced are solution processable red phosphorescent devices (CIEx=0.67, y=0.32) with 50,000 hours lifetime(2) and an efficiency of 11cd/A.
CDT also welcomes the announcement of a green material with color co-ordinates (CIEx=0.36, y=0.60), which represents a more saturated color than previously available from this class of material. Materials with strong colors are important in the design of full color displays with good efficiency and lifetime characteristics. Lifetime achieved for this material is 50,000 hours(3) with an efficiency of 16cd/A.
The increased performance demonstrated by these latest data has prompted a switch to reporting lifetimes extrapolated from the higher luminance of 400cd/m2.
Comments CDT's CEO Dr David Fyfe: "We are delighted to see rapid progress being made by the team from Sumation(TM), our joint venture operation formed in 2005. We place a very high priority on continuing to improve the underlying capability of P-OLED technology and the range of applications it can satisfy. We expect to continue to report further progress going forward. These data demonstrate the very significant synergy achieved with the combination of two very experienced teams in Cambridge and Tokyo." (1) Lifetime data has hitherto been reported by CDT from an initial
luminance of 100cd/m2. On this basis, the blue fluorescent devices
would have an extrapolated lifetime of 200,000 hours. (2) Equivalent to 800,000 hours from 100cd/m2. (3) Equivalent to 600,000 hours from 100cd/m2 About CDT
Cambridge Display Technology is a pioneer in the development of light emitting polymers (P-OLEDs) and their use in a wide range of electronic display products used for information management, communications and entertainment. P-OLEDs are part of the family of organic light emitting diodes, or OLEDs, which are thin, lightweight and power efficient devices that emit light when an electric current flows. P-OLEDs offer an enhanced visual experience and superior performance characteristics compared with other flat panel display technologies such as liquid crystal displays, and have the key advantage that they can be applied in solution using printing processes. Founded in 1992, the company is headquartered in Cambridge, UK and listed on the US NASDAQ National Market under the symbol 'OLED'. In 2005, CDT and Sumitomo Chemical established a joint venture called Sumation(TM), which develops, manufactures and sells P-OLED materials to the display industry.
