OLED with high efficiency blue light-emitting layer |
| abstract |
The invention provides an OLED device comprising an anode, a cathode and a light-emitting layer located therebetween, said light-emitting layer comprising an anthracene host and a styrylamine blue light-emitting compound; and, located between the said light-emitting layer and the cathode, a first electron-transporting layer that is greater than 0.5 nm and less than 5 nm thick; and a second electron-transporting layer consisting essentially of an anthracene located between the first electron-transporting layer and the cathode. The first electron-transporting layer includes a compound with a less negative LUMO level than the anthracene in the second electron-transporting layer. Devices of the invention provide improvement in features such as efficiency. |
