Patent abstract
Organic light-emitting devices having a multi-component organic electroluminescent layer. The organic electroluminescent layer comprises a phosphorescent dopant and a host material that is a mixture of at least three different compounds: a wide band gap host compound, an electron-transporting host compound, and a hole-transporting host compound. Use of such a multi-component organic electroluminescent layer may improve device efficiency and lifetime.
