Publication number: 20240119894Abstract: A display apparatus includes: a display; a display driver that drives the display such that the display displays in accordance with display data; and a host controller that transfers update display data of one screen to the display driver. The display driver includes a light-emission controller that causes a self-luminous elements to emit light, and a memory that stores the update display data of the one screen. The display driver reads the update display data on the memory after an elapse of a predetermined period of time from a drive end time at which the display controller finishes driving in accordance with the update display data and drives the screen by using the read update display data. The display driver drives the self-luminous elements once or more at a timing when the update display data from the host controller to the display driver is not updated.Type: ApplicationFiled: December 15, 2023Publication date: April 11, 2024Inventors: YUICHI SATO, KENJI MAEDA, SHINJI YAMAMOTO, TAKUYA OKAMOTO, FUMITAKA SEKI, MASAFUMI ITO, YOHICHI TAKAZANE

Patent number: 10594084Abstract: A connector that, when changing an actuator from an open state to a closed state provides a sound that indicates the actuator has changed to a fully closed state. In one embodiment, the actuator has an open surface, a closed surface, a sloped connection surface, and a tip load transmission portion. The open surface enables insertion of a connection object into an insertion portion in an open state. The closed surface is approximately parallel to the connection object in a closed state. The sloped connection surface connects the open surface and the closed surface. The tip load transmission portion is located at an intersection of the closed surface and the sloped connection surface, and elastically contacts the connection object at a time at which a pressing load imparted by an elastic pressing portion is at a peak.Type: GrantFiled: November 18, 2016Date of Patent: March 17, 2020Assignee: KYOCERA CORPORATIONInventors: Fumihito Ikegami, Masafumi Seki, Ryoichi Manabe

Publication number: 20180323546Abstract: A connector that, when changing an actuator from an open state to a closed state, allows for easy aural recognition that the actuator has changed to a fully closed state, and also has improved actuator operability is provided. An actuator (50) has an open surface (56O), a closed surface (56C), a sloped connection surface (56S), and a tip load transmission portion (56L). The open surface (56O) enables insertion of a connection object (20) into an insertion portion (31) in an open state. The closed surface (56C) is approximately parallel to the connection object (20) in a closed state. The sloped connection surface (56S) connects the open surface (56O) and the closed surface (56C). The tip load transmission portion (56L) is located at an intersection of the closed surface (56C) and the sloped connection surface (56S), and elastically contacts the connection object (20) at a time at which a pressing load imparted by an elastic pressing portion (43a) is at a peak.Type: ApplicationFiled: November 18, 2016Publication date: November 8, 2018Inventors: Fumihito IKEGAMI, Masafumi SEKI, Ryoichi MANABE
