OLED-TV Display/Monitor Technology News

CDT and Sumation have revealed new and improved results for green and blue P-OLED materials.

Data from spin coated devices using a common cathode and a recently developed solution processable green P-OLED material demonstrate lifetimes of 50,000 hours from an initial luminance of 1000cd/m2. This is equivalent to over 285,000 hours from an operating brightness of 400cd/m2 for this material and represents a 40% increase in lifetime compared to results announced in March.

Blue materials have now been developed with a demonstrated lifetime of 10,000 hours from an initial luminance of 1000cd/m2 (or 62,000 hours from an operating brightness of 400cd/m2) and a deeper colour.

CIE chromaticity coordinates for previously reported blues were x=0.14, y=0.21, whereas the latest materials are much deeper (x=0.14, y=0.19).
