OLED-T today announced a green phosphorescent OLED material with world class efficiency performance.

The new material called E255a has a high colour saturation making it ideal for a broad range of product applications in single colour and full colour displays. The material also has a very high efficiency delivering high brightness at low power making it ideal for mobile product applications with either passive matrix or active matrix driving.

The University of Hong Kong has manufactured OLED demonstrators using E255a and has reported a device efficiency of 40 cd/A at 1000 cdm-2 with a very saturated green colour coordinate of (0.28, 0.64) which is wider than commercially available LCD products.

E225a will be available for customer sampling from January 2008 and can be deposited onto any desired substrate by vacuum coating methods.
