Abstract
Systems and methods of displaying an end-of-life image on an electronic display are disclosed. An end-of-life image is displayed on a MEMS display device in the presence of sufficient water vapor and without continued activation of the display. The image can be displayed in response to user input, in response to detection of a predefined level of water vapor within the display package, according to a prestored lifetime of the device, or according to the natural expiration of the lifetime of the display device and packaging.
