Abstract
A diffuse reflective article is provided including a diffuse reflector of light positioned within a structure defining an optical cavity. The diffuse reflector is a nonwoven sheet containing a plurality of inter-fiber and intra-fiber pores of optimal light scattering dimension. Also provided is an optical display, including: (i) a structure defining an optical cavity; (ii) a light source positioned within the optical cavity; (iii) a display panel through which light from the light source passes; and (iv) a diffuse reflector positioned within the optical cavity for reflecting light from the light source toward the display panel, wherein the diffuse reflector is a nonwoven sheet containing a plurality of inter-fiber and intra-fiber pores of optimal light scattering dimension.
