Description

technical field

[0001] The invention relates to a phosphorescent material, in particular to a kind of phosphorescent material which can be used in the field of organic electroluminescence. 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. Three new display technologies emerging in recent years: plasma display, field emission display and organic electroluminescent display (OLED), all make up for the shortcomings of cathode ray tube and liquid crystal display to a certain extent. Among them, OLED has a series of advantages such as self-illumination, low-voltage DC drive, full curing, wide viewing angle, and rich colors. Compared with liquid crystal displays, OLED does not require a backlight, has a large viewing angle, low power consumption, and its response speed is faster than that of...
