Patent number: 11967294Abstract: A common electrode driver includes an inverting amplifier including a first resistor, a second resistor, and an operational amplifier, and a resistance ratio adjustment circuit that adjusts, in accordance with a length of one horizontal scan period, a resistance ratio being a ratio of a resistance value of the second resistor to a resistance value of the first resistor. A feedback voltage is provided to one end of the first resistor. The resistance ratio adjustment circuit sets the resistance ratio when second driving is performed, in which a length of one horizontal scan period is a second time longer than a first time, to be smaller than the resistance ratio when first driving is performed, in which a length of one horizontal scan period is the first time.Type: GrantFiled: May 1, 2023Date of Patent: April 23, 2024Assignee: Sharp Display Technology CorporationInventors: Masaki Uehata, Yasuki Mori, Kohji Saitoh, Takayuki Mizunaga, Kazuya Kondoh, Takashi Nojima, Kazuhisa Yoshimoto, Kosuke Kawamoto, Hiroyuki Kito, Kazuki Nakamichi
