  • Patent number: 9390662
    Abstract: A liquid crystal display device includes: a liquid crystal display unit that displays, for each of frames, an image based on an input image signal; a drive unit that applies a voltage based on the input image signal to pixels of the liquid crystal display unit; and a control unit that controls an amplitude of the voltage applied to the pixels. The drive unit applies, in one of the frames, a voltage of the same polarity to the pixels connected to one of the source signal lines. The control unit includes: a temperature-information acquiring unit that acquires temperature information of the drive unit; and a filter unit that acquires high-frequency and low-frequency components of the input image signal in a substantial extending direction of the source signal lines. The control unit controls the amplitude of the applied voltage using the temperature information and an output value of the high-frequency component.

  • Patent number: 7751013
    Abstract: TFTs are formed on a substrate. An interlayer insulation film is formed on the substrate to cover the TFTs. Lower layer portions of SD lines formed of a multi-layered film which are formed on the interlayer insulation film constitute a lower electrode of an organic EL layer. An uppermost layer of the SD line is formed of a chemically stable metal oxide film, and the SD layer is used as it is. On the other hand, as a lower electrode of an organic EL layer, an upper layer of the SD line is removed and an Al—Si, alloy film of the SD line is used. Due to such a constitution, it is possible to reduce a cost by shortening steps while holding the performance and the reliability of organic EL.
