Abstract

The invention discloses moisture transmittance testing equipment and a moisture transmittance testing method for a packaging material. The moisture transmittance testing equipment comprises a testing cavity, photographing equipment and a testing circuit, wherein a loading plate / rack and the photographing equipment are arranged inside the testing cavity; the testing circuit is connected with the loading plate / rack, is electrically connected with an article to be tested on the loading plate / rack and is used for performing electric testing on the article to be tested; the photographing equipment is used for performing optical testing on the article to be tested within at least a part of time that the article to be tested is subjected to electric testing by using the testing circuit. By adopting the equipment and the method, the purpose that electric testing and optical testing are implemented simultaneously is achieved on one equipment, so that the cost can be lowered, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of material moisture permeability measurement, in particular to a water vapor transmission rate testing device and method for packaging materials. Background technique [0002] OLED devices have outstanding advantages such as high contrast, wide color gamut, flexibility, thinness, and energy saving, and have bright prospects in the display field. However, the active metal used to form the metal cathode in OLED devices is very sensitive to water vapor and oxygen in the air. It is very easy to react with the infiltrating water vapor and affect the injection of charges. In addition, the infiltrated water vapor and oxygen will also chemically react with organic materials. These reactions are the main factors that cause the performance degradation of OLED devices and shorten the life of OLED devices. Therefore, packaging technology, especially the moisture permeability of packaging materials, is very important fo...
