2405 A Study on Multi-Objective Optimum Design of OLED Thin Film Structure for Improving Emission Properties

Abstract

Optical characteristics of design specifications required for organic light emitting diode are emitted light intensity, spectrum, color rendering and so on. The multi-objective design of the OLED thin film structure is studied for simultaneously satisfying these specifications using a weighted sum method and a satisficing trade-off method. It is hardly to balance between objectives with trade-off relationship in the weight sum method. On the other hand, it is possible to easily perform OLED thin-film structure design considering multiple emission properties by appropriately setting the aspiration level in the satisficing trade-off method.
