Abstract EN
Low light outcoupling efficiency restricts the wide application of organic light-emitting diodes in solid state light market although the internal quantum efficiency of the device could reach near to 100%.
In order to improve the output efficiency, different kinds of microlens array on the substrate emission surface were designed and simulated using light tracing method.
Simulation results indicate that the microlens array on the substrate could efficiently improve the light output efficiency and an enhancement of 1.8 could be obtained with optimized microlens structure design.
The microlens array with semicircle shape using polymer material was fabricated on glass substrate by a facile approach.
Finally, the organic device with microlens array substrate was manufactured and the light output of the device with surface microlens structure could increase to 1.64 times comparing with the device without microlens.
