In a case, where MinRGBnL?TH1 holds: the value of the signal for the white color sub-pixel is MinRGBnL/TH1, the value of the signal for the red color sub-pixel is RnL?MinRGBnL, the value of the signal for the green color sub-pixel is GnL?MinRGBnL, and the value of the signal for the blue color sub-pixel is BnL?MinRGBnL.Type: GrantFiled: August 9, 2013Date of Patent: April 18, 2017Assignee: SONY CORPORATIONInventors: Ryo Kasegawa, Akihito Nishiike

Patent number: 9626918Abstract: 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: October 20, 2014Date of Patent: April 18, 2017Assignees: Japan Display Inc., Panasonic Liquid Crystal Display Co., Ltd.Inventors: Shoichi Hirota, Shinichi Komura, Yoshifumi Sekiguchi, Tsunenori Yamamoto, Masaya Adachi

Patent number: 9626920Abstract: In a liquid crystal display device for performing pause driving, occurrence of flicker is effectively suppressed while an increase in power consumption is suppressed. When a frame in which an image signal (DAT) is inputted from an external portion without output of a request signal (RO) for requesting the external portion to input the image signal (DAT) is defined as a first input frame, a reversal driving control portion (10) sets the reversal driving technique in the first input frame to the column-reversal driving while setting the first input frame to a refresh frame defined as a first refresh frame, sets three frames subsequent to the first refresh frame to pause frames, sets a frame subsequent to the final pause frame to a refresh frame defined as a second refresh frame, and sets the reversal driving technique in the second refresh frame to the dot-reversal driving.Type: GrantFiled: November 13, 2013Date of Patent: April 18, 2017Assignee: Sharp Kabushiki KaishaInventors: Tatsuhiko Suyama, Kouji Kumada, Norio Ohmura, Noriyuki Tanaka, Takuya Sone
