    • Disclosed are a liquid crystal display device and a method and a circuit for driving the same. A gradation difference between the image data to be supplied to the picture elements of the same color of two pixels adjacent in a horizontal direction is detected in a gradation difference judging section, and when the gradation difference is larger than a predetermined gradation difference, it is judged in the same pattern of a size relationship detecting section and a horizontal pattern counting section whether the size relationship between the gradations of the picture elements of the same color of the two pixels repeats in the horizontal direction at least a certain number of times or not. And hence, when the size relationship repeats at least a certain number of times, it is compared with those of a plurality of lines continuously arranged in a vertical direction, and it is judged on the basis of the result of the comparisons whether a flicker occurs or not. And hence, when the flicker may occur over a plurality of frames, a polarity pattern switching signal is changed, whereby a polarity pattern which determines the polarities of the image data to be supplied from a data driver to a liquid crystal display panel is switched.
    • 公开了一种液晶显示装置及其驱动方法和电路。在灰度差中检测要提供给与水平方向相邻的两个像素的相同颜色的像素的图像数据之间的灰度差 判断部分,并且当灰度差大于预定灰度差时,以与尺寸关系检测部分和水平图案计数部分相同的图案判断相同颜色的图像元素的灰度之间的尺寸关系 的两个像素在水平方向上重复至少一定次数。 因此,当尺寸关系至少重复一定次数时,将其与在垂直方向上连续布置的多条线的那些进行比较,并且基于比较的结果来判断是否发生闪烁 或不。 因此,当在多个帧上发生闪烁时,极性图案切换信号被改变,从而切换将从数据驱动器提供给液晶显示面板的图像数据的极性确定的极性图案。

    • In a case where each of pixels of a liquid-crystal display panel is divided into two subpixels, the drive levels of the subpixels with respect to the gradation of an input video signal can be selected from among a plurality of drive levels while an increase in the circuit scale is suppressed.Thus, in the present invention, a first subpixel driving level converter for, on the basis of the gradation value of each pixel of the input video signal, obtaining a first gradation value for driving a first subpixel is provided, and the first subpixel is driven and controlled on the basis of the first gradation value. Then, the first gradation value obtained by the first subpixel driving level converter is converted into a luminance value, and a difference with the luminance value such that the gradation values of the whole pixels are converted is obtained. The obtained difference is converted into a gradation value, and a second gradation value for driving a second subpixel is obtained. The second subpixel is driven and controlled on the basis of the second gradation value.
