  • Publication number: 20220193968
    Abstract: The present disclosure provides a marbled molded product obtained by injection-molding, in a mold cavity, a mixture including: a thermoplastic resin including one selected from the group of polycarbonate, acrylonitrile-butadiene-styrene, polybutylene terephthalate, polypropylene, and combinations thereof; and fine pigment particles, where a pattern forming a texture is formed on the surface of the injection-molded product. The present disclosure also provides a system for evaluating a marble color effect of a marbled molded product, the system including: a light source unit, an image-capturing unit, an image processing unit and an evaluation factor determination unit.

  • Patent number: 11327211
    Abstract: An asymmetric transmission film including a body having a first surface and a second surface opposite to the first surface and a transmittance control member disposed in the body such that a forward transmittance of light passing in a direction from the first surface toward the second surface and a reverse transmittance of light passing in a direction from the second surface toward the first surface are different from each other.

  • Publication number: 20120268816
    Abstract: There is provided a Fresnel lens structure including: a Fresnel lens layer; and a planarization layer disposed on the Fresnel lens layer, any one of the Fresnel lens layer and the planarization layer being formed of a birefringent material and the other being formed of an isotropic material having a refractive index equal to a highest refractive index or a lowest refractive index of the birefringent material. In the Fresnel lens structure, a 2/3D image switching structure is simplified and switching thereof is easy. 2/3D switching can be performed without using an apparatus with complicated structure, whereby a stereoscopic image display apparatus structure may be simplified and manufacturing costs may be reduced as compared with a lenticular lens by using a Fresnel shaped lens structure.
