    摘要: Disclosed herein is an optical device including a light source and an optical article. The optical article includes a lightguide and a viscoelastic layer disposed on the lightguide. Light emitted by the light source enters the lightguide and is transported within the lightguide by total internal reflection. The viscoelastic layer manages light, for example, at least about 50%, or less than about 10%, of light that enters the lightguide may be extracted. The optical device can be used in a variety of constructions for signs, markings, display devices, keypad assemblies, tail light assemblies and illumination devices.
