    • The generation of flicker is prevented when the contrast of a displayed image is changed. The amplitude of the data voltage whose polarity is inverted at a timing synchronized with the display cycle of an image is changed based on the tone and the designed contrast. At the same time, the position (center) of 0 V relative to the amplitude of the data voltage is offset a larger amount as the contrast increases. This corrects a change V in voltage between the electrodes under the influence of the parasitic capacity of a TFT when the TFT is turned off, so that the voltage between the electrodes is also turned off despite the polarity of the data voltage applied to the liquid crystal, even when the designated contrast is relatively high and the amplitude of the data voltage is relatively small, and even when the designated contrast is relatively low and the amplitude of the data voltage is relatively large.
    • 当显示的图像的对比度改变时,防止产生闪烁。 在与图像的显示周期同步的定时,极性反转的数据电压的幅度根据色调和设计的对比度而改变。 同时,相对于数据电压的振幅,0V的位置(中心)随着对比度的增加而偏移较大的量。 这在TFT关闭时在TFT的寄生电容的影响下校正电极之间的电压变化V,尽管施加到液晶的数据电压的极性,电极之间的电压也被截止 即使当指定的对比度相对较高并且数据电压的幅度相对较小时,并且即使当指定的对比度相对较低并且数据电压的幅度相对较大时。
