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. The data-line driving circuit outputs the potential so that the positive-polarity output potential corresponding to a smallest output grayscale value becomes lower than a positive-polarity grayscale potential indicated by a smallest one of the display grayscale values and that the negative-polarity output potential corresponding to the smallest output grayscale value becomes higher than a negative-polarity grayscale potential indicated by the smallest one of the display grayscale values.

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.

In the case where the relative brightness of the video data of one or two of the three primary colors RGB changes from between 0 and 0.5 inclusive for the previous frame to between 0 and 0.5 inclusive for the present frame, the video image of the one or two colors is delayed by one frame and displayed.

摘要： A display device and system are disclosed, wherein the display system is so configured that an n-fold rate increasing circuit is arranged with a signal generating device instead of with the display device to realize a low-cost n-fold rate impulse-type drive. The n-fold rate display data is output to the display device from the signal generating device, and the display device includes a circuit to subject the input n-fold rate display data to the data conversion process for the n-fold rate impulse drive. In addition to the n-fold rate display data, an identification signal for identifying the position of the turn of the frames of the original video signal is input to the display device to prevent the erroneous data conversion operation.
