Patent number: 11847288Abstract: A touch panel includes a base substrate, a cover panel, a first electrode formed outside of a display region on a back surface of the cover panel, and a second electrode formed outside of the display region on a front surface of the base substrate. A pressure when the base substrate is pressed by the pointer through the cover panel is detected by measuring a change of a distance between the first electrode and the second electrode when the front surface of the cover panel is pressed as a change of electrostatic capacitance between the first electrode and the second electrode. The touch panel further includes a ground electrode formed on an outer peripheral side of the first electrode of the cover panel.Type: GrantFiled: February 3, 2021Date of Patent: December 19, 2023Assignee: Mitsubishi Electric CorporationInventors: Kageyasu Miyahara, Seiichiro Mori, Yusuke Shimasaki, Takeshi Ono, Tae Orita

Patent number: 10254896Abstract: A display includes a touch sensor panel, a panel controller, a case, and a signal generation circuit. The touch sensor panel includes a touch sensor. The panel controller measures a capacitance of the touch sensor. The case accommodates the display, in which at least the touch sensor panel and the panel controller are disposed. The signal generation circuit is capable of applying an AC signal to a ground of the panel controller. The case is electrically connected to the ground of the panel controller. When the signal generation circuit applies the AD signal to the ground, the panel controller measures the capacitance of the touch sensor.Type: GrantFiled: May 4, 2017Date of Patent: April 9, 2019Assignee: Mitsubishi Electric CorporationInventors: Seiichiro Mori, Yusuke Shimasaki, Kageyasu Miyahara, Yuichi Okano

Patent number: 10146370Abstract: In a touch panel device, an output control unit controls a process of outputting touch information acquired by a sensing unit and a touch detection unit of a touch sensor panel to host equipment, where the information indicates presence or absence and a coordinate of a touch of an indicator to the touch sensor panel. A state sensing unit senses an operation state of the sensing unit or the touch detection unit. A state restoration unit restores the sensing unit or the touch detection unit in the abnormal state to a normal state, based on a detection result of the state sensing unit. Upon detecting an abnormal state in the state sensing unit, an output control unit stops an output of the touch information to the host equipment for a fixed period of time.Type: GrantFiled: February 23, 2016Date of Patent: December 4, 2018Assignee: Mitsubishi Electric CorporationInventors: Seiichiro Mori, Kageyasu Miyahara, Yuichi Okano, Yusuke Shimasaki

Patent number: 9959642Abstract: A vector data selection unit selects, from a vector file of a past line graph, each vector data of a time period where a new line graph overlaps. An attribute value setting unit sets, of the vector data selected, a high transparency degree value to oldest vector data, sets a low transparency degree value to newest vector data, and sets an intermediate transparency degree value to intermediate vector data. A graph display unit displays a portion of a time period of the past line graph where the new line graph overlaps, with a gradation.Type: GrantFiled: September 25, 2014Date of Patent: May 1, 2018Assignee: Mitsubishi Electric CorporationInventors: Atsushi Hori, Daisuke Kisara, Kentaro Mori, Yuichi Okano, Kageyasu Miyahara, Masayuki Kimura
