제목 Multi-functional Al2O3/TiO2 multilayer thin film encapsulation for OLED as out-coupling enhancement and passivation layer.
초록 Organic light-emitting diodes (OLED) have great potential for use in next-generation flat-panel display due to their many advantages, such as their fast response, light weight, wider viewing angles and for use with flexible displays. It is still remain to solve the problem of low light-out coupling efficiency and short lifespan. One of the method to overcome low light extraction efficiency is that introduce the microcavity structure in OLEDs. We were fabricated top emitting OLED and then deposited stacks of Al2O3 and TiO2 layer for encapsulation using atomic layer deposition (ALD) process. The properties including electrical characteristics (I-V-L), EL spectra and water vapor transmission rate were investigated.
