Abstract
The present disclosure provides a packaging method and a package structure of a QLED device. The packaging method of the QLED device forming a thin film encapsulation layer in which a plurality of inorganic barrier layers and at least one organic buffer layer are arranged alternately on a QLED device to seal the QLED device against water and oxygen, and the organic buffer layer is further doped with a thermal conducting material, so that the heat generated by the QLED device can be promptly transmitted through the thin film encapsulation layer to improve the heat dissipation of the thin film encapsulation layer, thereby improving the light extraction efficiency and the service life of the QLED device.
