Abstract
In this thesis, we demonstrated the simulation results of optical performance of organic light-emitting devices (OLED) by different kind of microstructure attachment. The simulations include the intensity, luminance efficiency, power efficiency, blurred image, and blur-width of the device which is attached by different microstructures. For lighting applications, we focus on light extraction efficiency and intensity distribution. For display applications, we pay attention to blurred image and blur-width. We also take the power and luminance enhancement into consideration. Finally, we bring up an innovation about specific arrangement of microstructure array on OLED display. We conclude the design rule for some parameters such as size, area ratio, height ratio, and arrangement of microlens array.
