    Abstract: A driving method for a liquid crystal display element including L row electrodes and K column electrodes in which two kinds of data, data corresponding to a logical "0" and data corresponding to a logical "1", are used to display gray shades. The row electrodes are divided into row electrode subgroups which are selected as a batch. When the row electrode subgroups are selected, they have a positive voltage level with respect to a non-election voltage and a negative voltage level with respect to a selection voltage. A matrix of column vector components in which row voltages are time-sequentially arranged form a display cycle in each of the row electrode subgroups, and such a matrix has orthogonality. Row voltages are dispersively applied in a display cycle in each of the row electrode subgroups. Further, a number of column vector components K is related to a number of row electrodes L such that K is a minimum value satisfying the orthogonality and L is.ltoreq.2.sup.P =K, where K, L and P are integers. A gray shade is then effectuated by displaying a plural number of ON and OFF signs at a specified ratio.

    Abstract translation: 用于包括L行电极和K列电极的液晶显示元件的驱动方法,其中两种数据,对应于逻辑“0”的数据和对应于逻辑“1”的数据用于显示灰度阴影。 行电极被分成选择为批次的行电极子组。 当选择行电极子组时,它们相对于选择电压具有相对于非选择电压和负电压电平的正电压电平。 在每个行电极子组中,行电压按时间顺序排列的列矢量分量的矩阵形成显示周期,并且这样的矩阵具有正交性。 行电压分散地施加在每个行电极子组中的显示周期中。 此外,多个列向量分量K与行电极L的数量相关联,使得K是满足正交性的最小值,并且L是<= 2P = K,其中K,L和P是整数。 然后通过以指定的比例显示多个ON和OFF标志来实现灰色阴影。
