Abstract

The invention discloses a light-emitting compound with a structural formula I as shown in the specification. A light-emitting device prepared by the compound disclosed by the invention has better efficiency and lower driving voltage, and relatively stable light-emitting spectrum of the device can be maintained.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a luminescent compound. Background technique [0002] At present, TFT (Thin Film Transistor, Thin Film Field Effect Transistor)-LCD is the main display screen. Since it is a non-self-illuminating display, the light must be projected through the backlight and penetrate the polarizers in the TFT-LCD panel in sequence. , glass substrate, liquid crystal layer, color filter, glass substrate, polarizer and other related components, and finally enter the human eye for imaging to achieve the display function. However, its display screen has shortcomings such as slow response rate, power consumption, and narrow viewing angle in the actual application process, which is not enough to become a perfect display screen. [0003] Relatively speaking, OLED, as a new type of flat-panel display technology, does not require a backlight compared with the traditional LCD display method, and uses...
