Patent number: 10551664Abstract: In a color display device, when using white (W) sub-pixels in addition to subpixels of red (R) and green (G) plus blue (B) without increasing a wiring line number, the per-color pixel number in a unit area decreases so that the image resolution is deteriorated. The area and number of subpixels are adjusted in accordance with the visual sensitivity or luminosity required. Practically, the area of red (R) and blue (B) subpixels which are relatively low in luminosity is set to be about two times greater than the area of green (G) and white (W) subpixels that are relatively high in luminosity while letting the number of green (G) and white (W) subpixels be twice the number of red (R) and blue (B) subpixels. A larger subpixel is configured from a plurality of unit subpixels. A smaller subpixel is formed of a one unit subpixel.Type: GrantFiled: March 9, 2017Date of Patent: February 4, 2020Assignees: Japan Display Inc., Panasonic Liquid Crystal Display Co., Ltd.Inventors: Shoichi Hirota, Shinichi Komura, Yoshifumi Sekiguchi, Tsunenori Yamamoto, Masaya Adachi

Publication number: 20160233560Abstract: An object of the present invention is to provide a technology with which the time of stopping operations of storage battery groups in performing preventive maintenance and maintenance works of storage batteries in a power storage system can be reduced. In the power storage system of the present invention, a storage battery panel 3 transmits a first signal (F1) based on monitoring of states of storage battery packs 4 to a superordinate relay panel 2, and the relay panel 2 transmits a second signal (F2) based on the first signal to a superordinate power control device 1. A maintenance device 5 transmits, based on an operation of designating a storage battery panel 3 to be maintained by a maintenance person, a third signal (M) to the superordinate relay panel 2 of the storage battery panel 3 to be maintained, and the relay panel 2 masks and invalidates the first signal from the storage battery panel 3 to be maintained or the second signal based on the first signal in accordance with the third signal.Type: ApplicationFiled: September 17, 2014Publication date: August 11, 2016Applicant: Hitachi Chemical Company, Ltd.Inventors: Mitsuyoshi KANOH, Takashi HARA, Shoichi HIROTA, Akihiko EMORI
