METHOD AND DEVICE FOR PROTECTING OBJECTS FROM DEGRADATION BY LIGHT WITH SUSPENDED PARTICLE DEVICE LIGHT VALVES

摘要

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.

1. A display device for protecting objects from degradation by light comprising:
a backing configured to receive an object to be displayed; and at least one display element including a suspended particle device (SPD) directly or indirectly connected to the backing and shielding the object to be displayed from an exterior of the display device, the SPD used in the display element configured such that a transparency of the display element to visible light is adjustable based a voltage applied to the display element.
