Problems solved by technology

Most of the currently used inorganic films are evaporated by plasma generation methods such as sputtering or vapor deposition (CVD). When there are many residual gases in the organic film, the residual gases will be released, resulting in Decreased flatness of inorganic films, resulting in increased water vapor transmission rate (WVTR), which can adversely affect the protected device

Abstract

The invention relates to a compound, a composite composed of the compound, application and a display panel. According to the compound of the invention, a compound I participates in the cross-linking polymerization reaction of acrylic monomers, the number of free small molecules is reduced, so that the miscellaneous gas emission and the water vapor transmittance are reduced, and a formed packaging layer shows effective light transmittance; and meanwhile, the composite before curing reaction has excellent stability at normal temperature and can be stored for a long time.

Description

technical field [0001] The invention relates to the technical field, in particular to a compound and the compound, application and display panel of the compound. Background technique [0002] An organic light-emitting diode (OLED) display consists of a hole-injecting electrode (anode), an organic light-emitting layer, and an electron-injecting electrode (cathode). The organic light emitting device is generally attached on a substrate made of glass and covered with another substrate to prevent deterioration due to moisture or oxygen introduced from the outside. Currently, organic light emitting display devices are becoming thinner and thinner according to the needs of consumers. In order to solve this problem, organic light emitting display devices adopt a thin film encapsulation (Thin Film Encapsulation; TFE) structure. [0003] The thin-film packaging structure covers the display area of ​​the substrate (that is, above the organic light-emitting device), and its formation ...
