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

Patent number: 8994322Abstract: Since in existent charge-discharge control the battery direct current resistance of a lithium ion battery increases at a low temperature or in a low SOC, the battery voltage may possibly exceed greatly the maximum allowable voltage instantaneously due to over-voltage during charging or may possibly decrease greatly to less than the minimum allowable voltage during discharging. If the lithium ion battery continuously lies in such a state the battery performance is degraded abruptly. The battery resistance of a lithium ion battery module is estimated in accordance with SOC and temperature of the lithium ion battery module, and current to charge is set properly based on the estimated battery resistance.Type: GrantFiled: June 28, 2012Date of Patent: March 31, 2015Assignee: Hitachi, Ltd.Inventors: Hironori Sasaki, Tsunenori Yamamoto
