White organic light-emitting devices (WOLEDs) have a few technical merits for lighting application. Generally, doping-concentration and carriers-transporting effect inherent in traditional WOLEDs, however, complicate the optimization of device efficiency and color-stability characteristics. In this paper, we design and fabricate a novel WOLED concept,in which an alternant yellow and blue lighting stripe structure is used. We analyze the emission characteristic of this alternate stripe WOLED (AS-WOLED) as a function of yellow and blue stripe size and lighting angle. From the comprehensive analysis, trend in the dependence of emission characteristic on device structure is extracted, and accordingly, a general method for optimizing color characteristics of AS-WOLEDs is suggested.
