Problems solved by technology

[0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) is an organic electroluminescent device, which has the advantages of self-luminescence, wide viewing angle, high brightness and low power consumption. However, the light extraction efficiency of current OLED devices is low, and only About 20% of the light energy goes out of the OLED device
Therefore, the light extraction efficiency of OLED devices needs to be improved

The electrode can be used in an OLED device, the fold-shaped block copolymer layer can improve refraction, reflection, diffraction and the like of light, and meanwhile, the waveguide mode and the plasma mode of the OLED device are improved, so that light extraction is improved, and the light extraction efficiency is improved. The invention further provides a preparation method of the electrode, an OLED device and electronic equipment.

Description

technical field [0001] The application belongs to the technical field of electronic products, and in particular relates to electrodes and preparation methods thereof, OLED devices and electronic equipment. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) is an organic electroluminescent device, which has the advantages of self-luminescence, wide viewing angle, high brightness and low power consumption. However, the light extraction efficiency of current OLED devices is low, and only About 20% of the light energy exits the OLED device. Therefore, the light extraction efficiency of OLED devices needs to be improved. Contents of the invention [0003] In view of this, the present application provides an electrode and a preparation method thereof, an OLED device and electronic equipment, so as to improve the light extraction efficiency of the OLED device and facilitate the application of the OLED device. [0004] In a first aspe...
