Abstract
Organic light emitting diode (OLED) is used for lighting utilized as display of television, mobile phone, digital camera, and so on. Luminescence spectrum and radiant energy of light from OLED structure depends on film thickness and optical indexes of the thin film materials. The structural optimization of thin films is useful to satisfy the design specifications on luminescent color and energy efficiency. We developed the system using genetic algorithms which could simultaneously optimize film thickness and optical indexes of each layer. In this report, results of the optimization of OLED structure to increase the radiant energy with target spectrum are shown.
