Abstract
A method for detecting moisture in a display device having at least one display element includes incorporating at least one moisture detector in a predetermined location of the display device, the moisture detector including a material layer comprising metal formed between a first electrode and a second electrode. One or more display elements are encapsulated between a first and second shields. A resistance of the material layer is detected so as to determine a level of moisture.
