    • An LUT fixedly stores correction values to compensate for a pull-in voltage in pixels in a liquid crystal panel. In at least one example embodiment, the display control unit outputs an input video signal Xa, a video signal Xp of a previous frame read from a frame memory, and a pixel polarity indicating a polarity of a pixel applied voltage on the pixel basis, and outputs a correction value read from the LUT to a data line driving circuit as a video signal Xb after correction. The data line driving circuit performs alternate current driving, based on the video signal Xb after correction. The LUT stores different correction values between when a positive polarity voltage is applied and when a negative polarity voltage is applied, for at least a part of combinations of values of the input video signal Xa and the video signal Xp of the previous frame. This can reduce a difference in response speed between when the positive polarity voltage is applied and when the negative polarity voltage is applied, thereby enhancing display quality.
    • LUT固定地存储校正值以补偿液晶面板中的以像素为单位的拉入电压。 在至少一个示例性实施例中,显示控制单元输出输入视频信号Xa,从帧存储器读取的先前帧的视频信号Xp和表示像素基础上的像素施加电压的极性的像素极性,以及 在校正之后将从LUT读取的校正值作为视频信号Xb输出到数据线驱动电路。 数据线驱动电路根据校正后的视频信号Xb进行交流驱动。 对于输入视频信号Xa和前一帧的视频信号Xp的值的组合的至少一部分,LUT存储施加正极性电压和施加负极性电压之间的不同校正值。 这可以减小施加正极性电压时和施加负极性电压之间的响应速度差,从而提高显示质量。
