Publication number: 20240135876Abstract: A display device includes a display panel including pixels in one pixel column and a gate driver for sequentially providing scan signals to the pixels. Each of the pixels includes a light emitting element, a first transistor for controlling a current amount of driving current flowing through the light emitting element and a second transistor for transferring a data signal to a gate electrode of the first transistor in response to a corresponding scan signal among the scan signals. A first pixel among the pixels is electrically connected to a first data line, and a second pixel adjacent to the first pixel among the pixels is electrically connected to a second data line different from the first data line. A second scan signal provided to the second pixel partially overlaps with a first scan signal provided to the first pixel.Type: ApplicationFiled: October 6, 2023Publication date: April 25, 2024Inventors: Min Woo BYUN, Min Joo KIM, Seon I JEONG, Chae Han HYUN, Sung Chan HWANG

Patent number: 9100140Abstract: This invention relates to spreading code producing apparatus, which comprises: two phase shifters for spreading code which receive bits for determining spreading codes and phase information and producing spreading codes; and multiplexers which receive two spreading codes produced said two phase shifters for spreading code, receive bits through separate way which defines outputting order of the received two spreading codes and produce spreading codes with same length as said received two spreading codes. Therefore, many information using few spreading codes can be transmitted so that data transmission rate can be raised. Furthermore, communication service with high speed can be performed among communication devices using human body communication etc.Type: GrantFiled: May 3, 2012Date of Patent: August 4, 2015Assignee: INDUSTRY-ACADEMIC COOPERATION FOUNDATION, CHOSUN UNIVERSITYInventors: Youn-Tae Kim, Kun-Ho Park, Jang-Myoung Kim, Min-Joo Jeong, Chang-Hee Hyoung, Jung-Hwan Hwang, Sung-Weon Kang
