Abstract: This disclosure provides systems, methods and apparatus for reducing image artifacts that arise when a display is exposed to sunlight over time. Various implementations disclosed herein can be implemented to prevent charge injection from inducing a negative offset voltage shift for display elements in the display. In one aspect, a buffer layer is applied to block electrons from being photoelectrically ejected from a movable reflective layer of a display element and into a stationary optical stack of the display element.
