The anode structures of OLED have a crucial influence on the performances of devices. This paper introduces the research progress of top-emitting OLED anode structures, materials and performances in recent years. The different structure composite anodes of the top-emitting OLED devices were designed by combining with principles and quality requirements. The TFCalc optical simulation software and SimOLED simulation software were used to simulate and calculate the optical performances and devices performances of top-emitting OLED with different composite anodes. The results show that Al/ITO/MoO3, Al/Co/MoO3, Al/Ni/MoO3and Al/MoO3are the better composite anodes in the three and two layers OLED anode structures.
