20120171392 | Optical Films with Controlled Surface Morphology and the Method of Manufacturing the Same - Provided are an optical film for use in flat panel display (FPD) devices, and a method for manufacturing the same. Particularly, there is provided a method for imparting surface roughness to an optical film, which includes forming dented craters having a radius of curvature of 10 nm-100 μm on the surface of an optical film obtained by a solution casting process and forming a plateau between one crater and another crater. There is also provided an optical film obtained by the same method. | 07-05-2012 |
20120276240 | CASTING BELT FOR PRODUCING TRANSCENDENTAL WIDE WIDTH FILM - The present invention relates to a casting belt used for manufacturing an optical film by means of a solvent casting process, in more detail, a casting belt for producing a transcendental wide width film which is used to produce a film in a gel state by casting a dope when manufacturing a film that is used for a polarizer of liquid crystal displays or optical compensation films. | 11-01-2012 |
20130234083 | Cellulose Acylate Film - Provided are a cellulose acylate film used for optical compensation and additives used therefor and, more particularly, is a cellulose acylate film with mechanical physical properties, in particular, very improved modulus affecting film durability. | 09-12-2013 |
