Patent number: 8794799Abstract: An optical sheet having both of an excellent light condensing function and an excellent scratch resistance is provided. An optical sheet includes: a sheet-like main body; at least three or more first unit shaped elements arranged on one surface of the main body; and second unit shaped elements arranged on the one surface of the main body. Each of the second unit shaped elements extend in parallel with in one direction on a sheet surface of the main body. A height H1 of each of the first unit shaped elements from the one surface is higher than a height H2 of each of the second unit shaped elements. A rate of an area occupied by the first unit shaped elements on the one surface is not more than 10.0%, when observed along a normal direction nd relative to the one surface.Type: GrantFiled: October 29, 2010Date of Patent: August 5, 2014Assignee: Dai Nippon Printing Co., Ltd.Inventors: Akinobu Ushiyama, Akiko Tomita, Satoshi Goishihara, Hiroshi Kojima, Takayuki Shimada, Mitsuhiro Hamashima, Kazuo Matsufuji, Kazuki Tanaka

Patent number: 8792172Abstract: A light guide member includes a first light guide film, a second light guide film, a diffuser film and an atomization film superposed together one by one. The first light guide film includes a plurality of first light guide dots and the second light guide film includes a plurality of second light guide dots staggered with the plurality of first light guide dots. The plurality of first light guide dots and the plurality of second light guide dots reflect the light towards any directions and then make the light uniformly and brightly emit out from the first light guide film and the second light guide film. The diffuser film controls the luminance and improves the uniformity of the light. The atomization film atomizes the light and solves the problem of visible dots.Type: GrantFiled: August 25, 2010Date of Patent: July 29, 2014Assignee: Hon Hai Precision Industry Co., Ltd.Inventor: Chia-Chin Chiang

Publication number: 20140204608Abstract: The present invention relates to an optical film having an atypical pattern, a method for manufacturing same and a backlight assembly including the optical film. The optical film of the present invention includes: a base layer transmitting light incident from outside; and a pattern layer formed on one or both sides of the base layer, and having a surface structured of a continuously formed polygonal optical pattern having an irregular size and arrangement. Thus, hot-spots and bright lines occurring at a light source and a light entering unit may be prevented. Not only can the pattern density of the optical film be maximized to improve brightness, but strong bright points may be effectively scattered and distributed through the atypical pattern to provide the effect of improved light-shielding ability, thereby contributing to a reduction in the number of expensive optical films used in a backlight assembly and an improvement in brightness.Type: ApplicationFiled: March 20, 2014Publication date: July 24, 2014Applicant: SEKONIX CO., LTD.Inventors: Jin Sung Park, Gyu Hwan Hwang
