    摘要: A liquid crystal display device which includes one image signal line which is connected to a plurality of pixels, a scanning line drive part which outputs an ON voltage to the respective pixels in a predetermined order, and a data line drive part which outputs image signal voltages. The data line drive part outputs a gray level signal voltage corresponding to a gray level value of the pixel as an image signal voltage in a first period, and outputs a correction gray level signal voltage different from the gray level signal voltage as an image signal voltage in a second period which precedes the first period. The liquid crystal display device further includes a control part which generates the correction gray level signal voltage based on the gray level value of the pixel and one or plurarity of gray level values of pixels which precede the pixel in order.

    摘要: A resistive element is connected in series to a cathode terminal of an LED light source at a last stage (or an anode terminal of an LED light source at a first stage) of an LED chain, and a resistance value of the resistive element is configured to be variable in resistance value in accordance with a variation of voltage drops of the LEDs connected in series so that a resistance value of a resistive element connected to an LED chain having a large voltage drop has a smaller resistance value then a resistance value of a resistive element connected to an LED chain having a small voltage drop. With this configuration, the power, which has been wasted otherwise as heat in the backlight driver IC, may be dispersed to the resistive elements.

    摘要: In the case where the gray-scale value of the pixel X is the minimum gray-scale value, the data line driving circuit (4) outputs a video signal having a voltage obtained by correcting the positive polarity minimum gray-scale voltage corresponding to the minimum gray-scale value only when outputting a positive polarity video signal. In the above, the data line driving circuit (4) outputs the video signal having the voltage obtained by correcting the positive polarity minimum gray-scale voltage, using a voltage correction amount larger than that which is used in outputting the video signal having the voltage obtained by correcting the positive polarity gray-scale voltage corresponding to the intermediate gray-scale value.

    摘要: A push button-type switch device includes a pair of fixed contacts, an operable member to be pushed, an actuating member elastically deformable upon the operable member being pushed, a movable contact which short-circuits the pair of fixed contacts due to elastic deformation of the actuating member, and a limiting part arranged to limit a direction in which the operable member moves and making the operable member move in a fixed orientation. The limiting part includes a pair of link members that engage with each other, one ends of the link members rotatably supported by the base portion, and the other ends thereof slidably supported by the operable member. This produces a good click irrespective of a position where the operable member is operated.
