Cambridge Display Technology (CDT) has reported longer lifetime results for red light emitting polymers (P-OLEDs), which is almost double compared to findings announced in March.

Data from devices produced using the latest phosphorescent materials show lifetime of 98,900 hours from initial luminance of 400cd/m?, equivalent to over 1.5 million hours from 100cd/m?.

"We are now seeing tremendous momentum in our development of the full range of P-OLED materials," said 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."

Production of video capable OLED displays requires a full color range of red, green and blue with long lifetime and good efficiency, explained CDT. The efficiency of the phosphorescent red material is approximately 9cd/A, while the color coordinates are CIEx=0.67, y=0.32.
