Abstract

The invention discloses a compound for thin film packaging, a composition and a packaging thin film. The composition with the compound structure comprises a component A, a component B and a component C, wherein the component A is the compound for thin film packaging; the component B is a methacrylate monomer, an acrylate monomer, a methacrylate oligomer or an acrylate oligomer; the component C is a photopolymerization initiator and / or a free radical polymerization initiator; the packaging film comprises inorganic layers and organic layers which are alternately arranged in sequence, and the organic layers comprise the composition for film packaging. The problem that the surface of the organic film is etched is solved, the water and oxygen transmittance can be reduced, and the service life of a device is prolonged.

Description

technical field [0001] The present invention relates to the technical field of thin film encapsulation, and more particularly to a compound, a composition and an encapsulation film for thin film encapsulation. Background technique [0002] An organic light-emitting diode (OLED) display includes a hole-injecting electrode (anode), an organic light-emitting layer, and an electron-injecting electrode (cathode). The organic light-emitting device is usually attached on a substrate made of glass and covered by another substrate to prevent deterioration due to moisture or oxygen introduced from the outside. Nowadays, organic light emitting display devices are becoming thinner and thinner with the demands of consumers. In order to solve this problem, thin film encapsulation (TFE) structure is adopted in organic light emitting display devices. [0003] The thin-film encapsulation structure covers the display area of ​​the substrate (that is, above the organic light-emitting device),...
