Abstract

The present application relates to an encapsulating film, a reliability assessment therefor, an organic electronic apparatus comprising the encapsulating film, and a method for producing an organic electronic apparatus which has used the encapsulating film, and provides: a reliability assessment method which can predict the reliability of the encapsulating film before same is applied to the organic electronic apparatus, the encapsulating film blocking moisture or oxygen from the outside entering the organic electronic apparatus; and the encapsulating film which can block moisture with high reliability.

Claims17

Dependent claims

A method of evaluating reliability of an encapsulation film comprising:

providing an encapsulation film which comprises a metal layer, and an encapsulation layer formed on the metal layer and comprising a moisture adsorbent,
measuring a specular reflectance R of the encapsulation layer at a wavelength of 550 nm, and
determining the reliability of the encapsulation film by the measured value of the specular reflectance R of the encapsulation layer,
wherein the reliability of the encapsulation film is determined as excellent provided that the specular reflectance R satisfies the range of 6.5 or less,
wherein the specular reflectance R is represented by the following Equation 1:
R=SCI−SCE (Equation 1)
wherein the Equation 1, SCI is a total reflectance including normal reflection measured according to ASTM E1164-12E1, and SCE is a reflectance excluding normal reflection measured according to ASTM E1164-12E1.
