Research progress of quantum dots LED transmission layer
Quantum dots light-emitting diode(QLED)show a wide range of potential applications in display and solid-state lighting due to advantages of good coloration purity,narrow half-maximum emission bandwidth,long life of inorganic components,and simple synthesis process.In recent years,the performance of QLED is improved rapidly,and there is a trend to replace organic LED (OLED ).The selection of transmission layer materials of QLED plays a crucial role in improving the carrier injection of the device.The chemical property of the transmission layer and its interface can also have an impact on device stability and lifetime.Research status of QLED transmission layer is summarized,by analyzing the factors that restrict performance of QLED,the direction and method of its performance improvement are introduced,and the future development of QLED is looked forward to.
