Description
Summary:Experimental methods for the characterization of dryers for OLED/PLED applications were addressed and results are reported and compared. Different commercially available dryers were tested. It turned out that test conditions can significantly affect the results of the characterization. For example, dryers showing a low total theoretical capacity can, on the contrary, show very good performances if tested using methods and conditions closer to the operating conditions expected to occur inside OLED/PLED devices. The measured sorption performances were used to calculate how water concentration inside a display evolves during lifetime of the device itself. These calculations show the effect and the benefit that can be obtained by the use of a specific dryer. Different measurement methods were compared and considerations for the selection of a suitable charachterization test are given.
