Although the lifetime of OLED devic

Although the lifetime of OLED devices has increased to thousands of hours, there is still a large gap from the requirements of commercial applications, and with the device's work, its luminous brightness and efficiency have a significant tendency to decline. Commercially, it is generally required that the storage time of practical electronic devices should be more than 5 years, and the working life should be longer than 10 hours. The current OLED has not yet reached the practical requirements. Therefore, increasing the life and stability of OLED devices is still an important subject of current research!
