CAMBRIDGE, England, October 3 /PRNewswire-FirstCall/ -- Following quickly behind the recent announcement by Cambridge Display Technology (CDT) [Nasdaq: OLED] and Sumation(R) of rapid progress in the development of longer lifetime blue light emitting polymers, comes this announcement of similarly impressive progress on red materials.

Data from devices produced using these latest, solution processable, phosphorescent materials show lifetime1 of 98,900 hours from an initial luminance of 400cd/msquared, equivalent to over 1.5 million hours from 100cd/msquared.

This represents almost a doubling of the lifetime results announced as recently as March of this year.

Production of video capable OLED displays requires a full color range of red, green and blue with long lifetime and good efficiency. The efficiency of this phosphorescent red material is approximately 9cd/A, and the color co-ordinates are: (CIEx=0.67, y=0.32).

"We are now seeing tremendous momentum in our development of the full range of P-OLED materials", commented Dr David Fyfe, CEO of CDT. "This latest result demonstrates that our rate of learning and discovery is really accelerating bringing many more applications for P-OLED technology within reach in a short timeframe."

The company will be exhibiting at FPD International in Yokohama, Japan from 18th to 20th October, and will be pleased to welcome visitors at its booth - no. 461.

Note to Editors:

When 'lifetime' is discussed here, it refers to the time taken for the display/pixel to fall to half its initial stated luminance. Lifetime estimates are based on accelerated testing of simple test devices at several very high initial luminance levels, and use of these data to calculate predicted lifetimes at lower brightness levels. Translation of this single pixel data into performance in an RGB display system depends on a number of factors and requires a complex calculation and knowledge of the precise system design parameters such as aperture ratio, brightness, ink formulation and relative pixel areas.

About CDT

Cambridge Display Technology is a pioneer in the development of polymer organic light emitting diodes (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 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(R) which develops, manufactures and sells P-OLED materials to the display industry.
