    • In order to display an image on a liquid crystal display at a constant image quality independently of a change of the length of the period for applying voltages with the same polarity to the liquid crystal, the length of one cycle of a horizontal synchronizing signal inputted to an LCD unit from an information processor is counted and the amplitude of data voltage and the center of the amplitude are corrected so that the amplitude of the data voltage to be applied to the liquid crystal increases and a correction value for the center of the amplitude increases as the length of the period for applying data voltages with the same polarity to the liquid crystal decreases in accordance with the length of one cycle of the horizontal synchronizing signal and whether to perform gate overlap scan. Thereby, the absolute values (V) of inter-electrode voltages after the TFT is turned off are equalized independently of the polarity of data voltage to be applied to the liquid crystal both for a relatively long period and for a relatively short period.
    • 为了在液晶显示器上以与液晶相同的极性施加电压的周期的长度变化的方式以恒定的图像质量显示图像,输入到水平同步信号的一个周期的长度被输入到 对来自信息处理器的LCD单元进行计数,并且校正数据电压的幅度和幅度的中心,使得施加到液晶的数据电压的幅度增加,并且振幅中心的校正值增加 由于根据水平同步信号的一个周期的长度以及是否执行栅极重叠扫描,用于向液晶施加具有相同极性的数据电压的周期的长度减小。 由此,关闭TFT之后的电极间电压的绝对值(V)与在液晶上施加的数据电压的极性相比相当长而相当短。
