    • A liquid crystal apparatus includes a liquid crystal device formed by a pair of substrates having thereon a group of scanning electrodes and a group of data electrodes intersecting the scanning electrodes so as to form an electrode matrix, and a liquid crystal disposed between the substrates so as to form a pixel at each intersection of the scanning electrodes and the data electrodes; and temperature-detection means for detecting a temperature of the liquid crystal device. The liquid crystal device is driven by applying a scanning signal comprising a clear pulse, a write pulse and a correction pulse to the scanning electrodes and for applying data signals to the data electrodes in synchronism with the scanning signal, while changing a voltage level of the correction pulse based on temperature data from the temperature-detection means. As a result, the liquid crystal device can effect a stable display over the entire area even if it has a temperature distribution therealong.
    • 液晶装置包括由一对基板形成的液晶装置,该基板具有扫描电极组和与扫描电极交叉的一组数据电极,以形成电极矩阵,以及设置在基板之间的液晶,以便 以在扫描电极和数据电极的每个交叉处形成像素; 以及用于检测液晶装置的温度的温度检测装置。 通过向扫描电极施加包括清除脉冲,写入脉冲和校正脉冲的扫描信号并且与扫描信号同步地将数据信号施加到数据电极来驱动液晶器件,同时改变扫描信号的电压电平 基于来自温度检测装置的温度数据的校正脉冲。 结果,即使液晶装置具有温度分布,也可以在整个区域上实现稳定的显示。
