New OLED materials last 1.4 million hours, more efficient Samsung OLEDs coming

OLED technology used to suffer from short lifespan (counted in hours till 50% brightness). But the technology improves quickly. Universal Display unveiled new materials that are long-lasting. In fact their green-yellow lasts for 1.4 million hours (!) while the red lasts for 900,000 hours. Only the blue is still a major issue with only 20,000 hours. But it is improving, too.

The company's Phosphorescent materials are more efficient than fluorescent ones. Samsung is currently using just red PHOLED (with blur and green Fluorescent OLED materials) in their AMOLED displays, which results in a display that is 15% more efficient than an LCD (showing a video that has 40% 'on' pixels). Adding the green PHOLED will result in a display that is 30% more efficient than an LCD. Samsung is using this combination in their 5.5-Gen AMOLED plant that started mass production just a few days ago. So we can expect the new Samsung AMOLEDs to be much more efficient.

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu
