Publication number: 20240137511Abstract: Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. In video encoding and decoding, multiple partition blocks are generated by splitting a target block. A prediction mode is derived for at least a part of the multiple partition blocks, among the multiple partition blocks, and prediction is performed on the multiple partition blocks based on the derived prediction mode. When prediction is performed on the partition blocks, information related to the target block may be used, and information related to an additional partition block, which is predicted prior to the partition block, may be used.Type: ApplicationFiled: January 4, 2024Publication date: April 25, 2024Applicants: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTE, INDUSTRY-UNIVERSITY COOPERATION FOUNDATION KOREA AEROSPACE UNIVERSITY, HANBAT NATIONAL UNIVERSITY INDUSTRY-ACADEMIC COOPERATION FOUNDATIONInventors: Jin-Ho LEE, Jung-Won KANG, Hyunsuk KO, Sung-Chang LIM, Dong-San JUN, Ha-Hyun LEE, Seung-Hyun CHO, Hui-Yong KIM, Hae-Chul CHOI, Dae-Hyeok GWON, Jae-Gon KIM, A-Ram BACK

Patent number: 7993047Abstract: A backlight unit is disclosed which improves picture quality by preventing a bright line or a dark line from being visible in the center of the display area. The backlight unit includes a plurality of U-shaped lamps arranged in two columns, wherein curved portions of the two opposite U-shaped lamps are symmetrically positioned in the center of a display area. Each of the curved portions of the U-shaped lamps has a non-luminous part so that light is not emitted by the curved portions of the U-shaped lamps. Optical sheets are provided above the U-shaped lamps, and a reflective sheet is provided below the U-shaped lamps.Type: GrantFiled: June 29, 2005Date of Patent: August 9, 2011Assignee: LG Display Co., Ltd.Inventor: Dae San Lim
