Problems solved by technology

It is generally believed that metal has the best water molecule barrier ability, thermal conductivity and electrical shielding properties, but it is opaque and the surface is not smooth enough; glass has excellent chemical stability, oxidation resistance, electrical insulation and compactness, but mechanical Low strength and brittleness; while the density and oxidation resistance of the polymer encapsulation layer are far inferior to those of metal and glass, further improvement is needed

Abstract

This invention discloses an organic photoelectron component with composite protective layer, including a substrate, an organic photoelectron component and a composite protective layer consisting of n combined layers, wherein n is the integer and is not smaller than 1 and not greater than 100. The combined layer is composed of three modes: an inorganic material layer / organic material layer / inorganic material layer or an inorganic material layer / organic material layer or organic material layer / inorganic material layer. The position relationship of the combined layers in the protective layer includes: setting at one position or multiple positions of the upper layer, the lower layer, the periphery of the organic photoelectron component; setting between the substrate and the organic photoelectron component or at one side of the substrate. This component improves the property of the organic photoelectron component, greatly reduces the cost of the organic photoelectron component, and reduces the technical command and cost for the industrialization of the organic photoelectron component.

Description

technical field [0001] The invention relates to the technical field of organic optoelectronic devices, in particular to an organic optoelectronic device with a composite protective layer and a preparation method thereof. Background technique [0002] With the rapid development of information technology, profound changes have taken place in the field of information display. People have higher and higher requirements for display image quality and portability. Various new flat panel display technologies are emerging, such as liquid crystal display, plasma display , field emission display, organic electroluminescent display, etc., have driven the leapfrog development of the display industry.
