Patent number: 11980063Abstract: A display device includes a substrate including a display area and a non-display area adjacent to the display area. The non-display area includes a blocking region. An organic layer is disposed on the substrate. An emission layer is disposed in the display area of the substrate. An auxiliary pattern is disposed in the blocking region of the non-display area of the substrate. A thin film encapsulation layer is disposed on the substrate and overlaps the emission layer and the blocking region. The organic layer has a groove penetrating an entire thickness of the organic layer in the blocking region. The auxiliary pattern overlaps the groove. The auxiliary pattern includes a same material as a gate electrode disposed in the display area of the substrate.Type: GrantFiled: April 27, 2021Date of Patent: May 7, 2024Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Ki Hoon Kim, Deuk Jong Kim, Jae Hak Lee

Patent number: 9254775Abstract: Provided is an apparatus for controlling transport of a heavy load by which a transport vehicle smoothly transports a heavy load such as a rotor blade of a wind power generator, which has a high weight and a large length, without collisions or interferences by controlling movement of the heavy load according to a facility around a road or a peripheral environmental condition in a process of transporting the heavy load on the road with the transport vehicle, a transport vehicle, and a method of controlling transport of a heavy load. The apparatus includes: an adjusting unit configured to control rotation or movements of the heavy load so that collision or interference of the heavy load with a facility around a road or a peripheral environmental condition is prevented in a process of transporting the heavy load after the heavy load is fixedly mounted to the adjusting unit.Type: GrantFiled: December 17, 2013Date of Patent: February 9, 2016Assignee: DOOSAN HEAVY INDUSTRIES & CONSTRUCTION CO., LTD.Inventor: Ki Hak Lee

Patent number: 9013053Abstract: A multi-type wind turbine is provided such that a plurality of arms are combined with one tower in a radial direction, and a unit generator having a blade is provided at the plurality of arms, respectively, and at least two of the unit generators are rotated in opposite directions to each other. Furthermore, both ends of the arm may be located both sides thereof on the basis of the height directional central line of the tower to be fixed thereto or both ends of the arm may be located at one side of the tower to be rotatably combined therewith. Furthermore, the rotation speed and tilt angle of the blade of the unit generator may controlled in an individual manner or controlled in a grouped manner. Furthermore, the unit generator may include a main blade and a sub-blade which is smaller than the main blade.Type: GrantFiled: November 15, 2012Date of Patent: April 21, 2015Assignee: Doosan Heavy Industries & Construction Co., Ltd.Inventors: Ki Hak Lee, Sang Il Lee, Jong Po Park
