More progress in polymer OLED lifetime; red reaches 100,000 hours
Following recent news from Cambridge Display Technology (CDT.L) and Sumation -- its joint venture with Sumitomo Chemical - of rapid progress in the development of longer lifetime blue light emitting polymers, comes similarly impressive progress on red materials.
Data from devices produced using these latest, solution processable, phosphorescent materials show lifetime 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 in March. In this context 'lifetime' refers to the time taken for the display/pixel to fall to half its initial stated luminance.
Production of video capable OLED displays requires a full colour range of red, green and blue with long lifetime and good efficiency.
Momentum
CDT chief executive David Fyfe (pictured) said: “We are now seeing tremendous momentum in our development of the full range of P-OLED materials".
“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."
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.
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. They offer enhanced visual experience and superior performance 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.
