  • Patent number: 7675522
    Abstract: A display error occurs upon contention between writing of pixel data in a GRAM and reading of pixel data representing a scanning line including pixels which correspond to the pixel data above. Pixel data corresponding to pixels representing a scanning line stored in a latch circuit is displayed on a display panel, and when contention occurs between writing of pixel data in a GRAM and reading of pixel data corresponding to pixels representing a scanning line to the latch circuit from the GRAM, a controller delays reading of the pixel data corresponding to the pixels representing the scanning line and controls so as to perform reading of the pixel data corresponding to the pixels representing the scanning line to the latch circuit from the GRAM once again.

  • Publication number: 20050141155
    Abstract: A CPU has to spend a long time of the order of several tens to several hundreds ms, which is required for wait processing when all the voltages are generated, on wait processing and thus the CPU cannot perform other operations during the wait processing, resulting in low working efficiency on the startup of the CPU in a liquid crystal display device. A liquid crystal driving voltage generating circuit 540 includes a voltage generating/outputting circuit 543 which generates two or more kinds of voltages, each having a predetermined voltage value, and outputs the generated voltages, a counter circuit 541 of performing counting according to a control signal inputted with a predetermined period from the outside, and a voltage generation timing managing circuit 542 of managing the timing of generating voltage according to the performed counting (count control).

  • Publication number: 20050083084
    Abstract: It is necessary to reduce power consumption in a liquid crystal display device. A drive voltage generation circuit 201 including: a clock signal dividing circuit 204 which applies signal processing, which does not divide a frequency of a clock signal SG22 to be inputted from the outside during a display period T13 for performing basic display for always displaying a radio wave reception state or the like of a cellular phone within a liquid crystal display panel and divides the frequency on the basis of a standard decided in advance during periods other than the display period T13, to a clock signal; and booster circuits 202 and 203 which generate a predetermined voltage for performing basic display for always displaying a radio wave reception state or the like of a cellular phone within the liquid crystal display panel using the clock signal SG13, a frequency of which has been divided by the clock signal dividing circuit 204.

  • Patent number: 5218499
    Abstract: A thin film magnetic head for perpendicular magnetic recording includes a magnetic member lying on a wear-resistant substrate of a non-magnetic material and defining a return path for magnetic flux. The magnetic member has a main groove formed in one of its principal surfaces in parallel to a sliding surface adapted to face a magnetic recording medium, and a narrow groove formed in the same principal surface and crossing the main groove at right angles thereto. The main and narrow grooves are filled with a non-magnetic material. The magnetic member carries thereon a laminate formed immediately above the intersection of the main and narrow grooves, and consisting at least of a thin-film conductor coil, an interlayer insulating film, a main pole film and a head-protecting film which are formed one upon another. The narrow groove has a width which is larger than that of the main pole film. The magnetic member is connected to the main pole film through a via hole portion.

  • Patent number: 5198950
    Abstract: A thin-film magnetic head includes a magnetic member having a principal surface formed with a first groove extending in parallel to a sliding surface adapted to face a magnetic recording medium, a non-magnetic material filling the groove, and at least a thin-film conductor coil, an interlaminar insulating film, a main magnetic-pole film and a protective film formed one upon another. The magnetic member being connected to the main magnetic-pole film though a via hole portion. The head has an exposed laminated surface defining the sliding surface. The magnetic member has also a second groove formed in its principal surface, crossing the first groove at right angles thereto, and filled with a non-magnetic material. The conductor coil and films are formed on the magnetic member immediately above the intersection of the first and second grooves. The non-magnetic material in the second groove is exposed in the sliding surface.

  • Patent number: 5181151
    Abstract: A thin-film perpendicular magnetic recording and reproducing head including a magnetic member defining a return path and having a narrow groove formed in one of its principal surfaces in parallel to a sliding surface adapted to face a magnetic recording medium, a non-magnetic material filling the groove, and a multilayer film assembly formed above the groove and consisting at least of a thin-film conductor coil, an interlayer insulating film, a thick main pole film, a main pole film and a protective film formed one upon another. The magnetic member is connected to the main pole film through a via hole portion, and is exposed on the sliding surface in the vicinity of the main pole film so as to face the recording medium. A thin magnetic film serving as a magnetic shield covers the protective film and the sidewall surface of the head and is joined to the sidewall surface of the magnetic member.
