Abstract: Disclosed is a method of making a light-reflecting article comprising: mixing a polymer with a high-pressure gas or a supercritical fluid in an extruder to create a homogeneous single-phase mixture; and extruding the homogeneous single-phase mixture through a die to form an extrudate, wherein the resultant extrudate contains a polymer foam having micro voids with a mean cell diameter of no more than 200 ?m.

Abstract: Disclosed is an anti-UV reflector for distributing a light from a point light source or a linear light uniformly over a target. The anti-UV reflector mainly includes a light reflecting polymeric substrate and a protecting layer of anti-UV material provided on the polycarbonate substrate for reducing yellowing in the polycarbonate substrate. When a light from a point light source or a linear light illuminates the anti-UV reflector, UV radiation in the light is filtered or absorbed by the protecting layer thereby reducing yellowing in the polyearbonate substrate.

Abstract: The present invention relates to a diffusion plate used in a direct-type backlight module and a method for making the same. At least one of the surfaces of the diffusion plate has a microstructure constituted by repeated undulation that can refract and diffuse the incident light beams that enter the diffusion plate. Therefore, the paths of the light beams after entering the diffusion plate are changed, which raises the luminance of the backlight module.
