Description

technical field

[0001] The invention relates to the field of electronic devices, in particular to an organic electroluminescent device and a preparation method thereof. Background technique

[0002] Organic electroluminescent devices (OLEDs) have some unique advantages: (1) OLEDs are diffuse surface light sources, and do not require an additional light guide system to obtain large-area white light sources like light-emitting diodes (LEDs); (2) Due to the diversity of organic light-emitting materials, OLED lighting can design the required color of light according to needs. At present, both small molecule OLEDs and polymer organic light-emitting diodes (PLEDs) have obtained all colors of light including the white light spectrum. ; (3) OLED can be made on a variety of substrates such as glass, ceramics, metal, plastic and other materials, which makes the design of lighting sources more free; (4) OLED lighting panels can be made in the way of making OLED displays. (5) OLED can ...
