| Abstract: | The study and the application of organic light emitting displays(OLED) have gained a great development presently.Flexible organic light emitting device(FOLED) is an important direction of the development of OLED,and injects new energy into the application of OLED.This article reviews the study and development states of FOLED.Meanwhile,in order to prolong the lifetime of FOLED by choosing and studying the flexible substrate,this paper compares the advantages,disadvantages and development states of three types of flexible substrate such as ultra thin glasses,polymer and metal foil which are usually used in FOLED field.From the experiment analysis,it is an efficient way to prolong the lifetime of FOLED by designing an optimum structure and selecting the appropriate materials for light emitting layer and cathode.Another important process is to decrease the penetration of water and oxygen into the inner of FOLED.The brief explanation about the encapsulation methods of device based upon the polymer and ultra thin glasses are discussed. |
