Abstract

This invention discloses an organic photoelectron component with protective layer, including a substrate and an organic photoelectron component, further including a 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 organic material layer / hydrophilic material layer / organic material layer or an organic material layer / hydrophilic material layer or hydrophilic material layer / organic 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. The component is capable of conquering the shortness existed in the current technology and has novel structure; the flatness of the substrate surface is improved. The bonding property of the protective layer solves the problem of connection degree between components and effectively prevents the water and oxygen entering into the inner part of the 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 protective layer. Background technique [0002] Today, with the development of multimedia technology and the advent of the information society, the requirements for the performance of flat panel displays are getting higher and higher. Recently, three new display technologies have emerged: plasma display, field emission display and organic electroluminescent display (OLED), all of which have made up for the shortcomings of cathode ray tubes and liquid crystal displays to a certain extent. Among them, organic electroluminescent displays have a series of advantages such as active light emission, low-voltage DC drive, full curing, wide viewing angle and rich colors. Compared with liquid crystal display devices, organic electroluminescent devices have broad application prospects and are viewed as One of the most competiti...
