Abstract
A display device comprising a Suspended Particle Device film or other material for controlling the amount of illumination transmitted to an object from one or more light sources to protect the object from degradation by light is described. The display is capable of being dark when the object is not being viewed and being highly transmissive when the object is to be viewed. If desired, the display device may be controlled so as to provide a substantially constant amount of illumination when the object is viewed or intended to be viewed. A method of protecting an object using the display device is also provided.
