Patent number: 7173588Abstract: In a liquid crystal display device in which picture elements are arranged in a matrix form, a fixed time before a display data voltage is supplied to the picture element by a data line and a scan line, a pre-write voltage at a gradation value having a high speed of response to a change in gradation is supplied to the picture element regardless of the gradation value of a picture after response. When the display data voltage is supplied to the picture element, the pre-write voltage is always supplied to the picture element to thereby increase the response speed of liquid crystal constituting the liquid crystal display device regardless of the gradation value of a picture after response, so as to display quickly a picture on a display section.Type: GrantFiled: March 11, 2002Date of Patent: February 6, 2007Assignee: Sharp Kabushiki KaishaInventors: Koichi Katagawa, Katsunori Tanaka, Katsuhiko Kishida, Toshiaki Suzuki

Patent number: 6667730Abstract: A display has a display panel of a first aspect ratio and is able to display on the display panel an image of a second aspect ratio whose width element is larger than that of the first aspect ratio. The display has a gate driver, a data driver, and a timing controller. The gate driver sequentially selects gate lines of the display panel. The data driver stores data for one gate line and supplies the data to one of the gate lines selected by the gate driver. The timing controller supplies control signals to the gate and data drivers so that predetermined data is displayed in top and bottom non-image areas of the display panel during a vertical blanking period. The display is capable of displaying images of different sizes.Type: GrantFiled: October 31, 2000Date of Patent: December 23, 2003Assignee: Fujitsu Display Technologies CorporationInventors: Yoshihisa Taguchi, Katsunori Tanaka, Katsuhiko Kishida, Toshiya Onodera, Hirofumi Miyamoto, Mikio Oshiro
