The organic electroluminescent display (hereinafter referred to as OLED) has a series of advantages of self-luminescence, low-voltage dc driving, full curing, wide viewing angle, light weight, simple composition and process, etc., and compared with the liquid crystal display, the organic electroluminescent display does not need a backlight source, and has a large viewing angle, low power, a response speed 1000 times that of the liquid crystal display, and a manufacturing cost lower than that of the liquid crystal display with the same resolution. Therefore, the organic electroluminescent device has very wide application prospect.
With the continuous advance of the OLED technology in the two fields of lighting and display, people pay more attention to the research on efficient organic materials affecting the performance of OLED devices, and an organic electroluminescent device with good efficiency and long service life is generally the result of the optimized matching of device structures and various organic materials, which brings great opportunities and challenges for the design and development of functional materials with various structures for technicians in the field.
