Strategies to Achieve High-Performance White Organic Light-Emitting Diodes

As one of the most promising technologies for next-generation lighting and displays, white organic light-emitting diodes (WOLEDs) have received enormous worldwide interest due to their outstanding properties, including high efficiency, bright luminance, wide viewing angle, fast switching, lower power consumption, ultralight and ultrathin characteristics, and flexibility. In this invited review,...

Optical Simulation of Top-emitting Organic Light Emitting Diodes

An optical model based on classical electrodyanmics has beeb exploited to simulate the optical effects for the top-emitting organic light emitting diodes. The optical performance of the devices can be obtained through calculation of the power density in each planar thin film. The far field emission profile and spectrum are derived base on this model. Predicated optical performance is compared w...

Solution-processed transparent blue organic light-emitting diodes with graphene as the top cathode

Graphene thin films have great potential to function as transparent electrodes in organic electronic devices, due to their excellent conductivity and high transparency. Recently, organic light-emitting diodes (OLEDs)have been successfully demonstrated to possess high luminous efficiencies with p-doped graphene anodes. However, reliable methods to fabricate n-doped graphene cathodes have been la...

Silver Grid Transparent Conducting Electrodes for Organic Light Emitting Diodes

Polymer organic light emitting diodes (OLEDs) were fabricated using thin silver hexagonal grids replacing indium tin oxide (ITO) as the transparent conducting electrodes (TCE). Previous literature has assumed that thick metal grids (several hundred nanometres thick) with a lower sheet resistance (< 10 Ω/□) and a similar light transmission (> 80 %) compared to thinner grids would lead to OLEDs w...
