Organic light emitting diodes with self luminous, high luminous efficiency, high brightness, high contrast, the preparation process is simple, flexible, low threshold voltage, and wide operating temperature, fast response speed, the thickness of thin, wide viewing angle, anti vibration, impact resistance and so on a series of advantages, the white organic electroluminescent in the application of diode and solid state lighting is more common. White OLED is used to display the LCD market, is now the mainstream, its advantage is still outstanding, has been recognized to be the most promising development has become the mainstream display model.Application of white OLED in the lighting field is also good, with the characteristics of environmental protection and energy saving, lightweight and convenient is regarded as a rising star in the world of traditional lighting, LED lighting and have their own advantages, to create a new blue ocean of the two complementary lighting. However, the white OLED stability problem is still not improved, the efficiency and service life compared with theoretical expectations are still gaps, so developed a white OLED is stable and efficient and longevity is the key to the industrialization, marketization.Organic light emitting diodes with self luminous, high luminous efficiency, high brightness, high contrast, the preparation process is simple, flexible, low threshold voltage, and wide operating temperature, fast response speed, the thickness of thin, wide viewing angle, anti vibration, impact resistance and so on a series of advantages, the white organic electroluminescent in the application of diode and solid state lighting is more common.
