Publication number: 20120194776Abstract: A display device is provided and includes pixel electrodes, each including a plurality of electrode sections which are arranged parallel to each other. Each electrode section is bent approximately in the middle along its extension direction in plan view. The pixel electrodes include a center connection portion adapted to connect together the electrode sections at their bent portions, and include end connection portions adapted to connect together the electrode sections at their end portions, and include protruding portions each of which is formed by extending the end connection portion in such a manner as to protrude from the arranged electrode sections. The display device also includes a substrate on which the pixel electrodes are arranged, an opposed substrate provided to face the side of the substrate on which the pixel electrodes are formed, and a liquid crystal layer filled and sealed between the substrate and opposed substrate.Type: ApplicationFiled: March 14, 2012Publication date: August 2, 2012Applicant: SONY CORPORATIONInventors: Hironao Tanaka, Yoshihiro Sakurai, Harumi Okuno

Patent number: 7196968Abstract: A method of driving source lines is arranged as follows: One output signal line S61 of a source driver is connected to a plurality of lines corresponding to respective source lines SR7 through SB12, and these source lines from SR7 (starting data line) to SB12 (terminating data line) are grouped as one block (group). In each block, a signal voltage of a divided output is supplied to the source lines during a first horizontal period T, while a signal voltage whose polarity is opposite to that of the aforesaid output is supplied to the source lines in a second horizontal period that is after the first horizontal period. In each of the horizontal periods, the source lines SR7 through SB12 are subjected to sequential selection. In addition to this, the source line SB12 is selected before turning the source line SR7 off.Type: GrantFiled: November 12, 2004Date of Patent: March 27, 2007Assignee: Sharp Kabushiki KaishaInventors: Harumi Okuno, Junichi Yamada, Hisashi Nagata
