Description

technical field

[0001] The invention relates to an organic electroluminescent device, more specifically, to a double-layer organic electroluminescent device with high luminous efficiency and good stability. Background technique

[0002] Today, with the development of multimedia technology and the advent of the information society, the requirements for the performance of flat panel displays are getting higher and higher. In recent years, three new display technologies: plasma display, field emission display and organic electroluminescent display have made up for the shortcomings of cathode ray tubes and liquid crystal displays to a certain extent. Among them, organic electroluminescent displays have a series of advantages such as self-illumination, low-voltage DC drive, full curing, wide viewing angle, and rich colors. Low, its response speed can reach 1000 times that of liquid crystal display, but its manufacturing cost is lower than the liquid crystal display of the same r...
