Hybrid light emitting diodes（HyLEDs） attracted more and more attentions.The typical devices configurations were consist of polymer light emissive layer sandwiched between metal oxides layers which were used as charge injecting and transporting layers.Traditional polymer light-emitting diodes（PLEDs） needed rigorous encapsulation to keep the air-sensitive metal cathode from oxygen and water in the air,but rigorous encapsulation increased costs and made it difficult to fabricate large area products.Metal oxides have high chemical and physical stability,whose usage in HyLEDs as charge injecting and transporting layers can protect polymer emissive layer from oxygen and water in the air,and therefore,improved devices atmosphere stability.Inverse structure was usually used to fabricate HyLEDs,and bottom electrode is cathode,which was more convenience to be integrated with amorphous-silicon thin film transistor for active matrix organic light emitting diodes.After several years＇ studies,considerable progresses were made in enhancing HyLEDs performances and understanding devices mechanisms.The advantages of HyLEDs compared with traditional PLEDs were overviewed.Researches progresses were reviewed from two aspects that metal oxides were used in PLEDs of electron and hole injecting and transporting layer.An analysis of device mechanism was made.
