Description

technical field [0001] The present disclosure relates to the field of organic light-emitting technology, in particular to an organic light-emitting diode device and a preparation method thereof. Background technique [0002] Organic light emitting diode (Organic Light Emitting Diode, OLED) involves the technology of organic semiconductor materials emitting light under the action of an electric field. It can realize many advantages such as large area and flexible display, and has broad application prospects in flat panel display and lighting. [0003] As the performance of monochromatic OLEDs gradually matures, white organic light-emitting diodes (WOLEDs), as a new type of solid-state light source, has shown good application prospects in lighting and flat panel display backlight, and has attracted people. More and more attention. At present, in terms of luminous efficiency, commercialized OLEDs have already surpassed incandescent lamps (~10lm / W). However, the luminous effi...
