Publication number: 20230397473Abstract: A display device is disclosed. The display device of the present disclosure comprises: a housing, which is elongated and has a base; a roller rotatably provided on the base in the housing; a display panel, which is wound around or unwound from the roller; a module cover which is elongated in the longitudinal direction of the housing, and which has a plurality of segments sequentially arranged in the vertical direction of the display panel at the rear side of the display panel, so as to be wound around or unwound from the roller along with the display panel; and a foldable link which is positioned at the rear side of the display panel, of which one side is pivotably connected to the base, and of which the other side is pivotably connected to the upper side of the module cover to raise the display panel and the module cover while unwinding from the roller, wherein the base can be tilted at a predetermined angle with respect to the bottom of the housing.Type: ApplicationFiled: April 28, 2021Publication date: December 7, 2023Applicant: LG ELECTRONICS INC.Inventors: Donghwan JEONG, Kwaneun JIN, Jaeyong KIM, Changshik MIN

Patent number: 11584674Abstract: A curved glass manufacturing method includes: successively stacking a lower mold, flat glass, and an upper mold, thereby forming a mold assembly; moving the mold assembly to a first chamber and then heating the same; moving the mold assembly from the first chamber to a second chamber and then pressurizing the upper mold so as to move the upper mold downward, thereby molding the flat glass in a curved shape; moving the mold assembly from the second chamber to a third chamber and then slowly cooling the molded glass; and moving the mold assembly from the third chamber to a fourth chamber and then cooling the molded glass. An elastic member is arranged between the lower mold and the upper mold and configured to define a space between the upper mold and the flat glass, and the elastic member is compressed when the upper mold is pressurized.Type: GrantFiled: September 6, 2017Date of Patent: February 21, 2023Assignee: LG Electronics Inc.Inventors: Hanjong Yoo, Jinsoo Lee, Donghwan Jeong, Subin Ha, Minkyu Hwang

Patent number: 9380716Abstract: A mobile terminal having a case defining an external appearance thereof, and a method of manufacturing such a case, are provided. The case may include a base formed of a resin material and having a recessed portion, a sheet disposed within the recessed portion and formed of a material that is different from that of the base, the material of the sheet having greater rigidity than that of the base, and a reinforcing member filled between the base and the sheet to integrally couple the base and the sheet. The rigidity of the material of the reinforcing member may have an intermediate value between the rigidity of the base and the rigidity of the sheet.Type: GrantFiled: May 22, 2013Date of Patent: June 28, 2016Assignee: LG ELECTRONICS INC.Inventors: Myungsun Kim, Soobong Jo, Donghwan Jeong, Seongteg Woo, Joonho Yun, Moonchul Choi, Hyunseok Oh
