Description
Technical field
The present invention relates to display technique field, particularly liquid crystal display drive circuit, Liquid Crystal Display And Method For Driving.
Background technology
Traditional liquid crystal display comprises the liquid crystal layer between array base palte and the color membrane substrates being oppositely arranged and the color membrane substrates that is filled in array base palte, wherein, on array base palte, be provided with pixel electrode, on array base palte or color membrane substrates, be provided with public electrode, by controlling the electric field level between pixel electrode and public electrode, thereby control liquid crystal deflecting element, and then pixel picture.
Characteristic for fear of liquid crystal molecule is destroyed, liquid crystal molecule can not be fixed on always some turn to constant.Voltage between pixel electrode and public electrode in liquid crystal display is just divided into two kinds of polarity, and one is positive polarity, and one is negative polarity.When the voltage of pixel electrode is during higher than the voltage of public electrode, be referred to as positive polarity, otherwise, be negative polarity.No matter the voltage between pixel electrode and public electrode is positive polarity or negative polarity, all can there is the GTG of one group of identical brightness.So when the pressure reduction absolute value between pixel electrode and public electrode is while being fixing, no matter be that pixel electrode voltage is high or public electrode voltages is high, shown GTG is out the same, and the switched in opposite of liquid crystal molecule is fixed on thereby avoid liquid crystal molecule to turn to the characteristic destruction that a direction causes always.
Conventionally, liquid crystal display mainly has four kinds of opposed polarity inversion modes, frame reversion (frame inversion), row reversion (row inversion), row reversions (column inversion) and some reversion (dot inversion), the type of drive of its corresponding public electrode comprises two kinds: fixed voltage drives and demodulating voltage drives.In the prior art, fixed voltage driving can be reversed, go and reverse, be listed as and reverse and put and reverse by achieve frame, and demodulating voltage driving can only be reversed and go and reverse by achieve frame.
