摘要： A liquid crystal display device includes a plurality of pixel circuits, data lines, and a data-line driving circuit connected to the data lines. Each of the pixel circuits includes a pixel capacitance having one end provided with a common potential. In accordance with a grayscale value for one of the plurality of pixel circuits, the data-line driving circuit selectively outputs a positive-polarity signal and a negative-polarity signal to the one pixel circuit. The data-line driving circuit outputs the positive-polarity signal and the negative-polarity signal so that an average of a potential of the positive-polarity signal and a potential of the negative-polarity signal corresponding to the grayscale value changes in accordance with the grayscale value, a temperature, and a position of the one pixel circuit.

摘要： Provided is a liquid crystal display device, including: a data line; a plurality of pixel circuits; an output grayscale value generating circuit for outputting an output grayscale value obtained by correcting a display grayscale value indicating a grayscale potential having one of positive polarity and negative polarity; and a data-line driving circuit for selectively outputting an output potential having one of positive polarity and negative polarity corresponding to the output grayscale value to the data line.

摘要： A data line driving section (6) outputs a video signal voltage for each pixel to a data line (DL) for each predetermined period in order. In outputting a video signal voltage for a pixel, the data line driving section (6) outputs a gradation signal voltage having a voltage corresponding to a gradation value of the pixel as the video signal voltage during a second part of the predetermined period, and outputs a correction gradation signal voltage different from the gradation signal voltage as the video signal voltage during a first part of the predetermined period. A control section (4) changes a relationship between the correction gradation signal voltage and the gradation signal voltage based on a combination of the gradation value of the pixel and a gradation value of a pixel preceding the pixel.

摘要： A resistive element (115) 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 (116), and the resistive element (115) 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 resistive element connected to an LED chain having a large voltage drop has a small resistance value while a resistive element connected to an LED chain having a small voltage drop has a large resistance value. With this configuration, the power, which has been wasted otherwise as heat in the backlight driver IC, may be dispersed to the resistive elements.
