Kodak improves efficiency and lifespan of OLEDs

Kodak has developed new OLED material, which enables OLED displays and light fixtures, among other things, to achieve lower power consumption and a longer service life. Kodak has named the fabric EK-GD403.

In combination with Kodak’s base layer EK-BH109, ​​the EK-GD403 OLED material can be used to produce green OLEDs with an efficiency greater than 31 cd/A, with a service life exceeding 65,000 hours. The starting point for these values ​​is an initial luminance of 1000 candela per square meter.

Especially the longer lifespan makes the new technology according to Kodak suitable for use in TVs and as a light source in lamps. The lifespan of current OLEDs, such as Sony’s 11″ OLED TV, usually does not exceed 30,000 hours.

The new fabric is a so-called dopant material, a deliberate contamination of a base layer that, according to Kodak, controls color reproduction and increases efficiency.

According to an report of research firm Nanomarkets, the market for OLED materials in 2015 will have a total size of 2.7 billion dollars. Analysts at Nanomarkets have calculated that in that year 90 percent of OLED material is intended for use in lighting.
