technical field
[0001] The invention relates to the field of OLEDs, in particular to a material used in the field of OLEDs. Background technique
[0002] As a display screen, TFT-LCD is a non-self-illuminating display. The light must be projected through the backlight, and then penetrate the polarizer, glass substrate, liquid crystal layer, color filter, Glass substrates, polarizers and other related components finally enter the human eye for imaging to achieve the display function. In practical applications, TFT-LCD display screens have disadvantages such as slow response rate, power consumption, and narrow viewing angle, which are not enough to be a perfect display screen.
[0003] OLED, as a new display technology, has the characteristics of self-luminescence, and is prepared by using a very thin organic material coating and a glass substrate. These organic materials emit light when an electric current is passed through them. At present, the basic structure of an OLED ...
