Patent number: 9365025Abstract: A method for forming fine patterns includes (S1) closely contacting a cliche-forming film to a hard mold concavely patterned, thereby making a disposable cliche; (S2) coating an elastic blanket cylinder with ink or resin; (S3) compressing the elastic blanket cylinder to the disposable cliche to remove ink or resin on a surface of the elastic blanket cylinder at a portion contacting with a relatively protruded embossed portion of the disposable cliche; and (S4) transcribing ink or resin remaining on the surface of the elastic blanket cylinder to a substrate. This method allows simple and fast works and greatly reduces costs by adopting a disposable cliche that may be easily installed and removed. Also, this method may be effectively utilized to form a fine pattern of an electronic device or a display device such as color filter and electrode.Type: GrantFiled: April 14, 2008Date of Patent: June 14, 2016Assignee: LG CHEM, LTD.Inventors: Jie-Hyun Seong, Seung-Heon Lee, Young-Jun Hong, Ji-Su Kim

Patent number: 8444885Abstract: Provided is a method for making a privacy film. In the method, a nickel mold having desired intagliated patterns are prepared, and a curable resin is then injected into the nickel mold to prepare a master mold. A UV curable resin is injected into the master mold, and then cured to thereby form a film where uneven patterns are formed. A black ink is injected into a concave portion of the film. The method provides advantages such as process simplicity, excellent production efficiency, and low fabrication cost.Type: GrantFiled: December 29, 2009Date of Patent: May 21, 2013Assignee: LG Chem, Ltd.Inventors: Dong-Wook Lee, Soon-Yeel Lee, In-Seok Hwang, Seung-Heon Lee, Sang-Ki Chun, Jie-Hyun Seong

Publication number: 20100089262Abstract: A method of printing fine patterns prints a fine pattern on a substrate using an elastic mold with an intaglio pattern. This method includes applying a fine pattern printing ink to a surface of a patterned elastic mold; removing the ink applied to an embossed portion of the elastic mold by closely adhering an ink removing unit having a polymer resin or an organic compound with a surface energy from <a surface energy of the ink?2 erg/cm2> to <the surface energy of the ink+erg/cm> to the surface of the elastic mold and then detaching the ink removing unit therefrom; and closely adhering the elastic mold to a substrate to transcribe the printing ink thereto. This method allows forming a fine pattern with good quality since the ink applied to the embossed portion of the elastic mold may be effectively removed during a gravure process.Type: ApplicationFiled: March 7, 2008Publication date: April 15, 2010Inventors: Jie-Hyun Seong, Yang-Gu Kang, Seung-Heon Lee, Kyoung-Su Jeon, Soon-Yeel Lee, Hye-Jeong Lee

Publication number: 20100028540Abstract: A method for forming a black matrix includes (S1) applying a black matrix-forming ink to an intaglio-patterned elastic mold; (S2) removing an ink applied to an embossed portion of the elastic mold; (S3) transcribing the ink remaining in an intagliated portion of the elastic mold to a substrate; and (S4) curing and drying the ink transcribed to the substrate. The step (S2) may be performed in a way of closely adhering a surface of an ink removing unit having a surface energy from <a surface energy of the ink?2 erg/cm2> to <the surface energy of the ink+8 erg/cm2> to the embossed portion of the elastic mold and then taking away the ink removing unit from the embossed portion. This method allows forming a black matrix in a simple and economic way by applying the gravure process.Type: ApplicationFiled: March 7, 2008Publication date: February 4, 2010Inventors: Jie-Hyun Seong, Seung-Heon Lee, Hye-Jeong Lee, Soon-Yeel Lee, Kyoung-Su Jeon, Yang-Gu Kang
