Patent number: 10573223Abstract: A scan driver includes scan signal outputting circuits, at least one of the scan signal outputting circuits includes a driving circuit and a buffer circuit. The driving circuit includes driving transistors. The driving circuit provides first and second driving signals to first and second driving nodes, respectively by turning on or off the driving transistors in response to clock signals and a scan input signal. The buffer circuit includes buffer transistors. The buffer circuit outputs a scan signal at an output node by turning on or off the buffer transistors in response to the first and second driving signals. The at least one of the scan signal outputting circuits performs a back-biasing voltage applying operation on at least one of the driving transistors and the buffer transistors when the driving transistors and the buffer transistors are turned on or off.Type: GrantFiled: January 16, 2017Date of Patent: February 25, 2020Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Ji-Hye Kong, Ji-Su Na, Yong-Sung Park, Dong-Bum Lee, In-Ho Choi, Young-In Hwang, Min-Woo Byun, Hea-Min Jung
