  • Patent number: 9066094
    Abstract: There is provided a display device that includes a display portion and a drive compensation portion. The display portion line-sequentially displays, in an image display region, a first image based on a first image signal and a second image based on a second image signal, by sequentially switching the first image and the second image at a predetermined interval. The drive compensation portion performs predetermined drive compensation on the first image signal and the second image signal input to the display portion, in accordance with a position of the image display region, a luminance of the first image and a luminance of the second image. The predetermined drive compensation is performed such that an average luminance of the first image or the second image becomes substantially uniform in the image display region during a predetermined period that is shorter than the predetermined interval.

  • Patent number: 8760381
    Abstract: There is provided a display device including an array substrate including pixels arranged in a matrix manner and gate control circuits that scan gate lines of the pixels and that are provided on the array substrate such that the gate control circuits correspond to the respective gate lines of the pixels. Each of the gate control circuits includes a first output terminal that outputs a signal to each of the gate lines, and a second output terminal that outputs a signal that is supplied to a gate control circuit in a subsequent stage. When adjacent two of the gate lines are scanned simultaneously from an upper part of a screen by the signal output from the first output terminal of each of the gate control circuits, a gate on period is provided during which outputs from the first output terminals of adjacent two of the gate control circuits are the same.

  • Publication number: 20140116394
    Abstract: A fuel supply system for an internal combustion engine includes a heat exchanger that has a heat exchanging wall between a liquefied fuel passage and an engine coolant passage. Heated and vaporized fuel flowing out from the liquefied fuel passage of the heat exchanger is supplied to the internal combustion engine. A flow rate of liquefied fuel supplied to the liquefied fuel passage of the heat exchanger is set. A flow rate of engine coolant supplied to the engine coolant passage of the heat exchanger is determined on the basis of a temperature of the engine coolant supplied to the engine coolant passage of the heat exchanger such that nucleate boiling or transition boiling of the liquefied fuel in the set flow rate occurs near a boundary between nucleate boiling and transition boiling in the liquefied fuel passage.

  • Publication number: 20140043451
    Abstract: A plurality of parallax images which are time-divisionally displayed are processed so that correct parallax can be displayed even during motion picture display. When a plurality of image streams of input signals to the video signal processing unit 120 are captured or generated with the same timing, interpolation processing for generating an interpolated image in terms of time is performed on at least one of the plurality of image streams, and the change of the apparent parallax is suppressed. More specifically, interpolation processing in terms of time is performed, so that a time difference of a time at which interpolation images of a plurality of image streams are generated is the same as a time difference of operation for separating the corresponding parallax images.
