Patent number: 7928952Abstract: An image display device has a display pixel area having plural pixels arranged in a matrix fashion, plural signal lines for supplying display signal voltages to the pixels, and plural pixel selection lines for selecting pixels from among the pixels to be supplied with the display signal voltages. The pixel selection lines include Y-direction selection lines for selecting rows of the pixels arranged in the matrix fashion and X-direction selection lines for selecting columns of the pixels, and the image display device includes a circuit configuration in which the display signal voltages are supplied from the signal lines to only ones of the pixels each having selected simultaneously both of a corresponding one of the Y-direction selection lines and a corresponding one of the X-direction selection lines.Type: GrantFiled: August 22, 2008Date of Patent: April 19, 2011Assignee: Hitachi Displays, Ltd.Inventors: Hajime Akimoto, Mitsuru Hiraki, Hitoshi Nakahara, Takashi Akioka, Yoshiyuki Kaneko, Makoto Tsumura, Yoshiro Mikami

Patent number: 7423623Abstract: An image display displays image data on an image display part constructed by a display pixel array. In an image display in which image data input means for inputting image data so that the display pixel array has two neighboring areas having different frame rates (>0) is provided or image data is displayed on an image display part constructed by a display pixel array, there is provided image data input means which can input at least one moving image data and at least one still image data into the image display part at different frame rates (>0). A high precision image display can be realized hardly changing a display pixel rewriting speed. A moving image signal output circuit and a still image signal output circuit output image data to the display pixel array, and they are provided as circuit configurations independent of each other.Type: GrantFiled: February 23, 2005Date of Patent: September 9, 2008Assignee: Hitachi, Ltd.Inventors: Hajime Akimoto, Mitsuru Hiraki, Hitoshi Nakahara, Takashi Akioka, Yoshiyuki Kaneko, Makoto Tsumura, Yoshiro Mikami

Publication number: 20020024496Abstract: An image display which displays image data on an image display part constructed by a display pixel array, wherein an image data input circuit inputs image data into the image display part by selecting addresses in a row direction and a column direction of the display pixel array so that the display pixel array has two neighboring areas having different frame rates (>0). The display pixel array includes row direction address lines and column direction address lines. Display pixels of the display pixel array each include an AND functional circuit which is connected to one of the row direction address lines and one of the column direction address lines.Type: ApplicationFiled: October 15, 2001Publication date: February 28, 2002Inventors: Hajime Akimoto, Mitsuru Hiraki, Hitoshi Nakahara, Takashi Akioka, Yoshiyuki Kaneko, Makoto Tsumura, Yoshiro Mikami

Patent number: 5563465Abstract: An actuator includes piezo electric devices which are installed in contact with a drive head and a driven body which is contact-driven by the drive head. Thus, only one mechanism performs coarse motion and micromotion by forming a gap between the drive head and driven body. The high precision positioning mechanism can be miniaturized and constructed at a low price.Type: GrantFiled: April 12, 1994Date of Patent: October 8, 1996Assignee: Hitachi, Ltd.Inventors: Hitoshi Nakahara, Masakazu Ichikawa, Yuishin Tanaka, Sakae Saitou, Shigeo Moriyama

Patent number: 5506481Abstract: A device for digital convergence correction of raster distortion correction of a picture displayed on a screen of a display device using a cathode-ray tube, in which scanning lines include a first class of scanning lines, called correction scanning lines, on which correction points are positioned, and a second class of scanning lines, called interpolated scanning lines between the correction scanning lines. The correction points are positioned at intersections of the correction scanning lines and vertical lines. The correction data for the interpolated scanning lines are produced by vertical interpolation from the correction data of a certain number of vertically aligned correction points. Convergence adjustment, however, may be conducted for only part of the correction points, and the correction data of the remaining correction points may be obtained by interpolation.Type: GrantFiled: May 4, 1994Date of Patent: April 9, 1996Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Akira Wada, Kouji Minami, Hitoshi Nakahara, Yoshiki Ono
