Abstract: A backlight module includes an optical plate, a light source, and at least one optical film. The optical plate includes a light-emitting surface, a bottom surface and a side surface. The light source faces to the bottom surface or the side surface. The optical film is disposed above the light-emitting surface and includes a main body and at least one refractive part disposed on an end surface of the main body. The refractive part includes a plurality of microstructures and a substrate. The substrate is adhered to the end surface, and the microstructures are distributed in the substrate.

The light source faces to the bottom surface or the side surface. The optical film is disposed above the light-emitting surface and includes a main body and at least one refractive part disposed on an end surface of the main body. The refractive part has a plurality of microstructures. The refractive part has non-uniform thickness relative to the end surface along a side direction. A refractive index of the refractive part is different from a refractive index of the main body, such that a plurality of light rays are deflected toward different directions after passing through the refractive part.

Abstract: The present invention relates to a phase separated bicontinuous polymeric network structure of block copolymer with two phases interpenetrating each other. The width of each phase is 0.3 to 5 nm, respectively. The polymer chain segments in one of the continuous network phase are aligned in an extended ordered array. The other polymer chain segment of the same block copolymer is in an amorphous physical state, which constitutes the other continuous network phase. Polymeric materials made of this nano-scale bicontinuous network is a novel material exhibiting desired properties such as high clarity, high tensile strength and modulus, high toughness, good solvent cast processibility and retention of adequate mechanical properties up to a temperature much higher than Tg and/or Tm of each polymer chain segment.
