An image is displayed by light control using an electric field generated between the plural pixel electrodes and the plural common electrodes. The presence or absence of touch is detected by a difference in capacitance due to the presence or absence of a material interrupting the electric field generated between one of the detection electrodes and one of the common electrodes. Each of the detection electrodes includes a through hole.Type: GrantFiled: March 13, 2014Date of Patent: April 19, 2016Assignee: Japan Display Inc.Inventors: Takahiro Miyazaki, Masanari Saitou, Koji Nagata, Shinji Sekiguchi, Tomohiko Ootani

Patent number: 9281679Abstract: A load circuit operates by power supplied from a power supply apparatus. A capacitive element is connected in parallel with the load circuit. A switching element is connected between the power supply apparatus and the load circuit in series with the power supply apparatus and the load circuit. A monitor section monitors voltage of the capacitive element and is connected in parallel with the capacitive element. An inrush current control section changes resistance of the switching element on the basis of the voltage monitored by the monitor section in order to control inrush current that flows at the time of an electronic device being plugged into or unplugged from the power supply apparatus. A breaker circuit prevents electric charges stored by the capacitive element from flowing into the monitor section at the time of the electronic device being unplugged from the power supply apparatus.Type: GrantFiled: May 17, 2013Date of Patent: March 8, 2016Assignee: FUJITSU LIMITEDInventor: Takahiro Miyazaki
