Abstract: The invention relates to an anti-streaking method for liquid crystal display, comprising: generating a periodic pulse voltage signal; applying the periodic pulse voltage signal to a common electrode of liquid crystal display, periodically fully biasing all pixels during the pulse generation, to generate periodic black picture. All pixels are fully biased during the pulse generation, causing the light transmissivity to be nearly lowest, thus generating periodic black screen, by applying the periodic pulse voltage signal to the common electrode of LCD, thus effectively mitigates the streaking phenomena of moving image due to the persistence of vision. Meantime, since the periodic black screen intermittently damages the fixed voltage applied on the liquid crystal, the liquid crystal molecules are subject to a strong reordering process periodically, thus the appearance of remnant image can be mitigated.
