UDC PHOLED material performance update - green now reaches 1.4 million hours

Universal Display has quietly released a new PHOLED material performance chart. Their Green-Yellow material now has 1.4 million lifetime hours (LT50), and their Red color offers 900,000 hours. Blue is still very challenging, and their light blue offers only 20,000 hours (LT50). Here's the complete chart:

The company also released some PHOLED material efficiency. Using only red PHOLED (with green and blue fluorescent materials) will result in a display that is about 15% more efficient compared to an LCD (this is the combination Samsung used in their 4.5-Gen AMOLED fab). Adding green color will result in a a display that is 30% more efficient compared to an LCD (this is the combination Samsung is using in their new 5.5-Gen fab). Adding blue will give a 50% more efficient display. UDC says that further enhancements (not specified) can result in a display that is 67% more efficient than an LCD. All these results are based on a 4" display operating at 300 cd/m² showing a video that has 40% pixels on.

UDC reported P²OLED (solution processable) material advances back in April, and now they released great charts showing the advances made since 2005 in terms of lifetime and efficiency:
