OLED STABILITY VIA DOPED HOLE TRANSPORT LAYER |
摘要 |
An organic light emitting device is provided. The device includes an anode and a cathode. A first organic layer is disposed between the anode and the cathode. The first organic layer is an emissive layer that includes a first organic emitting material. The device also includes a second organic layer disposed between the anode and the first organic layer. The second organic layer is a non-emissive layer. The second organic layer includes an organic small molecule hole transport material having a concentration of 50 to 99 wt %, and an organic small molecule electron transport material having a concentration of 0.1 to 5 wt %. Other materials may be present.
