Patent number: 11935458Abstract: A display device includes: a first pixel connected to a first data line and a first scan line; a second pixel connected to the first data line and a second scan line; a first scan driver connected to a first scan start line and the first scan line; and a second scan driver connected to a second scan start line and the second scan line. In a first frame period, the second scan start line is to be suppled with a second scan start signal having a turn-on level, after a first period elapses after a first scan start signal having a turn-on level is supplied to the first scan start line. In a second frame period, a difference between a time at which the first scan start signal having the turn-on level is supplied and a time at which the second scan start signal having the turn-on level is supplied corresponds to a second period. The second period is shorter than the first period.Type: GrantFiled: June 27, 2022Date of Patent: March 19, 2024Assignee: Samsung Display Co., Ltd.Inventors: Ji Hyun Ka, Ki Myeong Eom, Kyong Hwan Oh, Hai Jung In

Patent number: 11936075Abstract: Disclosed are a separator for fuel cells capable of minimizing the volume of a system and the use of sealants, and a stack for fuel cells, more particularly, a stack for solid oxide fuel cells, including the same. Specifically, by adding a metal sheet having a specific shape, position and size to the separator, the stress applied to the sealant can be uniformized, and thus the oxidizing agent and fuel can be separated and electrically isolated using only a piece of sealant. Therefore, the stack for fuel cells is characterized in that there is no variation in temperature, reactant concentration, power, or the like between respective unit cells, so delamination and microcracks do not occur, the volume is minimized, and the power density per unit volume is very high.Type: GrantFiled: December 21, 2021Date of Patent: March 19, 2024Assignee: Korea Institute of Science and TechnologyInventors: Jong Ho Lee, Kyung Joong Yoon, Ji Won Son, Seong Kook Oh, Sang Hyeok Lee, Dong Hwan Kim, Min Jun Oh
