Abstract

The invention relates to the technical field of a semiconductor, and particularly to an OLED device. An RCLEL layer is arranged between an electron transport layer and a hole transport layer; the RCLEL layer can effectively prevent accumulation of electric charges in a film layer interface between the electron transport layer and the hole transport layer, so that a condition that a non-luminous center is formed on the film layer interface caused by the accumulated electric charges is prevented; in addition, the RCLEL layer also has a reversible electrochemical oxidization reduction property, so that material deterioration caused in the transport process of electrons and holes can be greatly relieved; and diffusible ions and impurities also can be effectively prevented from entering a luminous layer, so that the service life of the device is prolonged.

Description

technical field

[0001] The invention relates to the technical field of semiconductors, in particular to an OLED device. Background technique

[0002] OLED, organic light-emitting diode, has self-illumination, simple structure, ultra-thin, fast response, wide viewing angle, low power consumption and flexible display lamp characteristics. It is known as "dream display" and is considered to be the ideal next generation Flat panel display technology. However, OLED is only used for mobile phones and tablets at present, and its lifespan has always been one of the important factors restricting its application in the TV and vehicle fields. Therefore, improving the lifespan of OLEDs will help expand its application fields.

[0003] At present, there are many technologies and structures to improve OLED efficiency and reduce OLED driving voltage, but one of the reasons restricting the wide application of OLED is that its lifespan cannot be compared with that of liquid crystals and LED...
