Abstract

The invention discloses an organic light-emitting device. The organic light-emitting device includes: an organic light-emitting device arranged on a substrate, and a packaging layer which covers a light-emitting layer. The packaging layer comprises at least one inorganic layer and at least one organic layer. Wherein a buffer layer is arranged between one inorganic layer and one organic layer whichare adjacent to each other; wherein the buffer layer is made of at least one of a tetramethylsilane monomer, an ethoxysilane monomer and a silicon oxycarbide monomer, and the buffer layer is used forenhancing the bonding strength between the inorganic layer and the organic layer and improving the bending resistance of the organic light-emitting device; moreover, the organic layer is made of thetransparent polyamide resin material, so that the impact resistance of the organic light-emitting device is improved.

Description

technical field [0001] The present application relates to the field of display of organic electroluminescent devices, in particular to an organic electroluminescent device. Background technique [0002] Foldable flexible organic electroluminescent devices (OLEDs) have attracted widespread attention in the industry and become a research hotspot in the field of display. The metal electrodes of organic electroluminescent devices are easily oxidized under the action of oxygen, and the organic light-emitting materials will be oxidized or crystallized under the action of water and oxygen, so that the light-emitting field of organic electroluminescent devices will be reduced, and even black spots (darkspots) will be generated. ). Therefore, most organic electroluminescence devices use encapsulation layers to protect the devices. [0003] The encapsulation layer of a common organic electroluminescent device forms a sandwich structure of inorganic layer / organic layer / inorganic laye...
