Patent number: 9881540Abstract: A gate driver includes first and second shift registers and a selector. The first shift register outputs first pulses. The second shift register outputs second pulses different from the first pulses. The selector selects one of the first pulses or the second pulses. When the selector selects the first pulses, the gate driver generates a first gate signal including first and second high periods, and output the first gate signal to a first gate line. The second high period is apart from the first high period by a first interval. When the selector selects the second pulses, the gate driver generates a second gate signal including the first high period and a third high period, and output the second gate signal to the first gate line. The third high period is apart from the first high period by a second interval different from the first interval.Type: GrantFiled: June 22, 2016Date of Patent: January 30, 2018Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Hyoung-Rae Lee, Moon-Ju Kim, Eun-Suk Kim, Seok-Kun Yoon, Kwang-Youl Lee, Young-Min Choi, Jong-Won Choo
