摘要:
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.

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.

A light diffusing assembly includes: a diffuser plate exhibiting a light scattering effect; a brightness-enhancing sheet for enhancing brightness of light passing therethrough; and an intermedium sandwiched between and in face-to-face contact with the diffuser plate and the brightness-enhancing sheet and having a refractive index greater than air and less than that of the diffuser plate.

Disclosed is a method of making foamed polymer beads, which comprises: 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 granulate foamed polymer beads each containing micro voids inside.

A method for forming an optical element includes: preparing an optical substrate; coating a curable resin on the optical substrate so as to form a curable resin layer on the optical substrate; embossing the curable resin layer so as to form a plurality of adjoining pointed micro-protrusions, each of which has a tip end; heating the pointed micro-protrusions of the curable resin layer in such a manner that the tip end of each of the pointed micro-protrusions is softened and is spread over the remainder of the respective one of the pointed micro-protrusions so as to form the adjoining pointed micro-protrusions into adjoining rounded micro-protrusions which cooperatively form a continuous curved surface; and curing the curable resin layer.

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 μm.
摘要:
A light diffusing assembly includes: a diffuser plate exhibiting a light scattering effect and having a light-emerging surface; and a brightness-enhancing film exhibiting a light concentrating effect and formed directly on the light-emerging surface of the diffuser plate. The brightness-enhancing film has a roughened surface opposite to the light-emerging surface of the diffuser plate.
