| titleOfInvention | Cap layer material and preparation method, organic electroluminescent device and display device |
| abstract | The invention discloses a capping layer material and a preparation method, an organic electroluminescent device and a display device, belonging to the technical field of chemical and organic light-emitting materials. The general structural formula of the capping layer material is: In the formula, X, Y, and Z independently represent any one of O, S, CR 3 R 4 , SiR 5 R 6 , and NR 7 . When the above-mentioned capping layer material is used as the capping layer of an OLED device, the light extraction efficiency of the OLED device can be improved. In addition, the capping layer material has a small extinction coefficient in the blue light region, and hardly absorbs blue light, which is conducive to improving the luminous efficiency, and at the same time effectively blocks the water and oxygen in the external environment, and protects the OLED device from water and oxygen. Erosion can improve the luminous efficiency and service life of OLED devices. |
