    • A liquid crystal display is provided which has low power consumption, and which prevents horizontal stripes from occurring without the circuitry becoming more complex. When the write voltage polarity is inverted every plurality of lines, in the n line where the polarity is inverted, the rise in the drain line waveform dulls due to the charging of the drain line. In the n+1 line, because the drain line has been charged by the writing of the n line, waveform dullness does not occur. A difference between the write states in the two lines causes horizontal stripes. Consequently, the output enable signal is activated at the rise of the clock signal, and the gate line is activated after a predetermined time to start the writing. Therefore, writing is not performed during the period of waveform dullness, and the write state is the same across all scan lines.
    • 提供了具有低功耗的液晶显示器,并且防止水平条纹发生,而电路变得更加复杂。 当写入电压极性每多行反转时,在极性反转的n行中,由于漏极线的充电,漏极线波形的上升变钝。 在n + 1行中,由于通过n行的写入对漏极线进行了充电,因此不会发生波形钝化。 两行之间写入状态之间的差异会导致水平条纹。 因此,在时钟信号的上升时,输出使能信号被激活,并且在开始写入的预定时间之后激活栅极线。 因此,在波形迟钝期间不进行写入,写入状态在所有扫描线上相同。
