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

Patent number: 11916038Abstract: Substrates that are bonding targets are bonded in ambient atmosphere via bonding films, including oxides, formed on bonding faces of the substrates. The bonding films, which are metal or semiconductor thin films formed by vacuum film deposition and at least the surfaces of which are oxidized, are formed into the respective smooth faces of two substrates having the smooth faces that serve as the bonding faces. The bonding films are exposed to a space that contains moisture, and the two substrates are overlapped in the ambient atmosphere such that the surfaces of the bonding films are made to be hydrophilic and the surfaces of the bonding films contact one another. Through this, a chemical bond is generated at the bonded interface, and thereby the two substrates are bonded together in the ambient atmosphere. The bonding strength ? can be improved by heating the bonded substrates at a temperature.Type: GrantFiled: October 7, 2022Date of Patent: February 27, 2024Assignees: CANON ANELVA CORPORATION, TOHOKU UNIVERSITYInventors: Takayuki Saitoh, Takayuki Moriwaki, Takehito Shimatsu, Miyuki Uomoto
