Abstract: The present disclosure pertains to an electromagnetic-wave shielding film and a preparation method thereof. The electromagnetic-wave shielding film includes a first metal layer, an insulating layer, and a second metal layer. The first metal layer has two opposite surfaces. The insulating layer is disposed on one of the surfaces of the first metal layer. The second metal layer is disposed on the other surface of the first metal layer and contains nano metal particles and an binder. The electromagnetic-wave shielding film can be used in a printed circuit board, and shows a satisfactory electromagnetic wave shielding effect.

Abstract: An optical film composite includes a brightness enhancement element and a light diffusion element, wherein the light diffusion element includes a substrate with a light diffusion layer on at least one side thereof, and wherein the light diffusion element has a haze of no less than 98% as measured according to JIS K7136 standard method.

Abstract: In this disclosure, a blue colorant is added in the adhesion layer of a reflective polarizer to compensate the chromaticity difference caused by the reflective polarizer itself and large horizontal viewing angle. The chromaticity difference can be further reduced by adding beads in the adhesion layer and/or forming light-gathering microstructures on the outer surface of the quarter wave plate of the reflective polarizer.

Abstract: The present invention provides a backlight module, which at least includes: a light guide plate having a plurality of V-cuts on both sides, in which the valley line of the V cut extends as a straight line and the valley lines of the V cuts on the same side of the light guide plate are parallel to each other, while the valley lines of the V cuts on the different sides of the light guide plate are non-parallel to each other; a reflective film disposed on the lower side of the light guide plate; at least a light source disposed around the light guide plate; and a single optical film disposed on the upper side of the light guide plate, in which the optical film includes a substrate and a plurality of light-adjusting structures.

Abstract: Disclosed herein is a light uniforming polarization recycling film comprising a cholesteric liquid crystal layer having a first optical surface and a second optical surface; an optical support formed on the first optical -surface; and alight scattering layer formed on the second optical surface. The light scattering layer includes a ¼ wavelength (quarter wave) plate and a microstructure layer having light diffusing characteristics. The light uniforming polarization recycling film according to the present invention can facilitate the elimination of chromaticity difference with respect to different visual angles and enhance the brightness of the polarizing film of recycling light.

Abstract: A coating composition comprises a resin, an antistatic agent and an antistatic aid, wherein the antistatic aid is selected from a group consisting of a siloxane compound, a fluoro-compound and a combination thereof. The antistatic aid can generate a synergy effect with the antistatic agent, and carry the antistatic agent out of the coating surface, thus can obviously reduce the amount of antistatic agent to achieve the desired antistatic effect by using a small amount of antistatic aid. The coating composition can be applied to various products with antistatic needs.
